Regulation of Dietary Supplements

Congress passed the Dietary Supplement Health and Education Act (DSHEA), which President Bill Clinton signed into law the same year. One provision of DSHEA clarified the definition for dietary supplements outlined above. DSHEA also mandated the establishment of the Office of Dietary Supplements (ODS) within the National Institutes of Health. The ODS coordinates research on dietary supplements and acts as a clearinghouse for regulatory issues. It also maintains an excellent resource for consumers, the International Bibliographic Information on Dietary Supplements (IBIDS), which is a database that contains citations published in scientific journals on the topic of dietary supplements. The public can access IBIDS on the ODS website. DSHEA established a new regulatory framework for supplement safety and for the labeling of dietary supplements by the U.S. Food and Drug Administration (FDA). Dietary supplements are regulated under food law, but with certain provisions that...

Controversies Surrounding the Use of Dietary Supplements

Public Health and School of Medicine, writes that DSHEA modifies the regulatory environment so that it becomes possible, even likely, that products will be marketed that inadvertently harm people (Zeisel, p. 1855). Zeisel believes that the DSHEA legislation makes it easy for small enterprises to market products without investing the time and money needed to prove their product's safety and efficacy. He contrasts the development of a new dietary supplement to that of a new drug or food additive, for which there is a formal process to evaluate safety. A manufacturer developing a new drug or food additive must conduct safety studies following FDA procedures. Results must be submitted to the FDA for review and approval before the ingredient or drug can be sold to the public. This is not the case for dietary supplements, however, because under DSHEA they are legally in a class by themselves. The FDA must simply be notified of the new product, and the notification must provide information...

Oral Nutritional Supplements

Mixed macro- and micronutrient liquid sip feeds and other oral nutritional supplements (bars, powders, and puddings) are widely used in the treatment of malnutrition in the community setting. A systematic review of 78 randomized controlled trials (RCTs) (including 44 RCTs from the community setting) suggests oral nutritional supplements can improve energy and nutrient intakes, improve body weight (or attenuate weight loss), and improve a number of functional and clinical outcomes in various patient groups (Table 2). Meta-analysis of RCTs from both hospital and community settings suggests significantly lower mortality (odds ratio, 0.62 95 confidence interval, 0.49-0.78) and complication rates (infections and postoperative complications) (odds ratio, 0.29 95 confidence interval, 0.18-0.47) in patients given oral nutritional supplements (typically 1.05-2.5 MJ (250-600 kcal) daily).

What about nutritional supplements

If it's not possible to get this help, many people benefit (quite safely) from taking a good-quality multivitamin and mineral supplement. Regularly taking a fish oil and or linseed (flax) oil supplement containing essential fatty acids is also often found to be beneficial. Health food shops or pharmacists sell nutritional supplements or you may get some supplements on prescription.

Potential Benefits of Dietary Supplements

The 2000 Dietary Guidelines for Americans (new release due 2005) emphasizes choosing foods sensibly, maintaining a healthy weight, and exercising regularly. It acknowledges that some people may need a vitamin-mineral supplement to meet specific needs. Similarly, the Food and Nutrition Board and the American Dietetic Association also recognize that dietary supplements may be desirable for some nutrients and for some individuals. The following is a compilation of recommendations by these groups

The Dietary Supplement Health and Education Act of 1994

Dietary supplement usage in the United States has increased significantly since the passage in 1994 of the Dietary Supplement Health and Education Act (DSHEA, pronounced Dee-shay). This legislation defined dietary supplements as distinct from food and drugs, and it allowed them to be sold without a prescription. The passage of DSHEA provided consumers with the right to purchase dietary supplements that they felt would help them attain their personal health goals. At the same time, DSHEA transferred to consumers the responsibility for making informed choices about the supplements that they used. In contrast to prescription and over-the-counter drugs, where effectiveness and safety must be demonstrated prior to marketing of the drugs, premarket approval is not required of manufacturers of dietary supplements. As a result, there is a greater potential risk that dietary supplements may be ineffective, or even harmful, as compared with drugs. The dietary supplements industry is not...

The Dietary Supplement Health And Education Act Dshea Of 1994

The current U.S. approach to the regulation of herbal products is rather complex and generally considered to be unsatisfactory. Until 1994, the FDA classified most herbal remedies as either food additives or drugs, and manufacturers had to meet strict FDA standards before placing their products on the U.S. market. This changed in 1994 when Congress enacted the Dietary Supplement Health and Education Act (DSHEA), which placed herbs together with vitamins and minerals in a category know as dietary supplements. DSHEA defines a dietary supplement as follows

What Is a Dietary Supplement How Are They Regulated in Different Countries

Each country has developed regulatory definitions and systems that place dietary supplements, particularly botanicals, into categories of drugs, traditional medicines, or foods. However, in the late 1980s, many countries launched major changes in regulations that may or may not have been approved at the time of this writing. Many regulations are still in draft form. The US Congress defined the term 'dietary supplement' in the Dietary Supplement Health and Education Act (DSHEA) of 1994. A dietary supplement is a product, taken orally, that contains a 'dietary ingredient' that is intended to supplement the diet. The dietary ingredient includes vitamins, minerals, herbs or other botanicals, amino acids, a dietary substance for use by man to supplement the diet by increasing the total dietary intake (e.g., enzymes or tissues from organs or glands), or a concentrate, metabolite, constituent, or extract. Dietary supplements may be found in many forms, such as tablets, capsules, softgels,...

Uicnih Center for Botanical Dietary Supplements Research University of Illinois at Chicago College of Pharmacy

The UIC NIH Center for Botanical Dietary Supplement Research is a new initiative, designed to employ a multidisciplinary approach in studies involving the clinical safety and efficacy of botanicals. One initial focus will be on herbs used to treat women's health, such as black cohosh (Cimicifuga racemosa) and red clover (Trifolium pratense), which show promise in the relief of symptoms associated with menopause.

Compilations of Composition Data for Dietary Supplements

As the use of dietary supplements increases worldwide, there is an increasing need to quantify intakes of nutrients and botanical products from these sources. Compiling nutrient profiles of such products into tables can be very time-consuming because the number of products continues to grow and formulations of existing products often change over time. Furthermore, average analytic data are seldom available from the supplement manufacturers, and thus database compilers must rely on whatever information is available from the product label. In many countries, a label showing the amount of each nutrient in the product is required.

Dietary Supplementation for Active Individuals

The use of nutritional supplements in athletes and in the health-conscious recreationally active population is widespread, as it is in the general population. A very large number of surveys have been published. A meta-analysis of 51 published surveys involving 10 274 male and female athletes of varying levels of ability showed an overall prevalence of supplement use of 46 , but the prevalence varies widely in different sports, at different levels of age, performance etc., and in different cultural backgrounds.

Dietary Supplements An Advertising Guide for Industry

The Federal Trade Commission (FTC) has responsibility for monitoring the advertising of dietary supplements in print and broadcast advertisements, infomercials, catalogs, and similar direct marketing materials. Such advertising must be truthful, substantiated, and not misleading. The FTC has taken action against supplement manufacturers, advertising agencies, distributors, retailers, catalog companies, and others involved in the deceptive promotion of herbal products. (See Chapter 11 for more information on the role of the FTC.)

Vitamin Supplementation

Currently, several large-scale intervention trials are underway to determine if B vitamin supplements (folic acid, B12, B6), which effectively lower blood homocysteine levels, reduce the incidence of vascular disease (Table 3). If proven effective, such supplements would be an inexpensive and relatively Table 3 Intervention trials to determine the effect of B vitamin supplements on homocysteine and the risk of vascular disease innocuous means by which the risk of vascular disease may be reduced. However, it must be recognized that if these trials are successful, they will not serve as definitive proof that homocysteine is a vascular toxin. It may be the case that one or more of the B vitamins influences vascular disease risk through separate mechanisms. For example, several studies have shown that low B6 status has an association with vascular disease independent of homo-cysteine. The uncertain relationship between hyperhomocysteinemia, B vitamins, and vascular disease is summarized...

Dietary Supplements

The demand for dietary supplements in the United States catapulted what was once a cottage industry into a 14 billion per year business in the year 2000. In 1994, the U.S. Congress formally defined the term dietary supplement as a product taken by mouth that contains a dietary ingredient intended to supplement the diet. The dietary ingredients in these products may include vitamins, minerals, herbs, amino acids, enzymes, organ tissues, glandulars, and metabolites. Dietary supplements can also be extracts or concentrates, and may be found in many forms, such as tablets, capsules, liquids, or powders. The use of dietary supplements is widespread they are taken by half of American adults. But the use of supplements is not limited to adults. A study published in the November 2001 Journal of the American Dietetic Association showed that dietary supplement use is prevalent among students as well, with 17.6 percent of 1,532 eighth-graders reporting the use of a vitamin-mineral supplement....

Background And Relevant Pharmacokinetics

Unfortunately L-GIn is not very soluble or stable in solution, especially upon heating for sterilisation, and as a result, until recently, was not included in TPN. The more soluble and stable giutamine dipeptides are now commonly used as the delivery forms in TPN solutions and some nutritional supplements (Kohlmeier 2003,

Agerelated Cataract Prevention

A large cross-sectional survey of 2873 volunteers aged 49-97 years detected a link between dietary vitamin supplement and a lower incidence of both nuclear and cortical cataract. Vitamin A, niacin, riboflavin, thiamine, folate and vitamin B12 all appeared to be protective, either in isolation or as constituents of multivitamin preparations (Kuzniarz et al 2001).

Anticancer

Twenty patients with various end-stage cancers were given 500 mg twice daily for 6 months. After 6 months 16 patients were still alive with a statistically significant increase in both NK function and TNF-alpha levels. Haemoglobin, haematocrit and glutathione levels were all greatly increased (See et al 2002). Although these results are interesting it is difficult to examine the direct effect of Andrographis paniculata as many other nutritional supplements were given concurrently.

Resistance Training

Studies in female athletes have shown no effect on body composition or muscle strength following supplementation of 500 fjg chromium picolinate daily during 6 weeks of resistance training (Livolsi et al 2001). In a clinical trial of older women a high-dose chromium picolinate supplement did not affect body composition, skeletal muscle size or maximal strength above that of resistance training alone (Campbell et al 2002). A meta-analysis of trials of dietary supplements for enhancing lean muscle mass and strength during resistance training did not support the use of chromium for this purpose (Nissen & Sharp 2002).

Multivitamins

Overall, acute toxicity is unlikely with combination vitamin supplements unless huge amounts have been ingested. In the case of toxicity or side-effects, signs and symptoms will relate to the individual nutrient ingested. In general, gastrointestinal symptoms such as discomfort, nausea and diarrhoea are the most frequent adverse effects.

Migraine

Gamma-linolenic acid may be beneficial in the prevention of migraine headache when used in combination with other nutritional supplements and as part of an overall management plan, according to an open, prospective, uncontrolled trial involving 168 migraine patients. In the study, patients took a combination of GLA and alpha-LA (1800 mg day), other vitamins, coenzymes and antioxidants, and were instructed to lower their arachidonic acid intake. They were also instructed on correct techniques of self-medication and in stress-reduction and progressive relaxation techniques. Of the 129 patients who were evaluated after 6 months, 86 reported an improvement, with 22 of the total being free from migraine, while 14 were not able to implement the self-management of progressive relaxation and stress reduction techniques. Severity and frequency of attacks were decreased in patients reporting a positive response. Significant reduction in nausea and vomiting was reported in all groups except the...

The Need for Nutrients

The needs for your particular lifestyle must be adequately covered, preferably through eating more of the appropriate kinds of foods, but also in cases where nutritional deficiencies are causing health problems, the use of nutritional supplements may also be helpful. For example, if you smoke and drink alcohol frequently your nutritional needs will be higher. If you are pregnant, if you

Determination of Requirements

Having decided an appropriate criterion of adequacy, which will differ from one vitamin to another, the problem is to determine what are adequate intakes to meet those criteria. Studies of vitamin requirements can be divided into the following four groups. 1.2.3.2 Depletion Repletion Studies There have been a number of studies to determine vitamin requirements by deliberate depletion of initially healthy subjects, following the development of biochemical and clinical signs of deficiency, then determining the intake required to reverse those signs. Such studies permit reasonably precise estimation of requirements to meet different criteria of adequacy and give some indication of the extent of individual variation. The number of subjects studied in this way has been relatively small, and estimation of requirements has generally been by interpolation into the results of experiments using a relatively wide range of intakes and is thus subject to considerable possible error. Such studies,...

Total Amounts Of Antioxidants In Foods

Referred to the antioxidant food table published as an electronic supplement to the paper by Carlsen et al. (2010) for the FRAP results on all 3139 products analyzed. The updated database is available online at www.blomhoff.no (link to Scientific Online Material). The categories Spices and herbs, Herbal traditional plant medicine, and Vitamin and dietary supplements include the most antioxidant-rich products analyzed in the study. The categories Berries and berry products, Fruit and fruit juices, Nuts and seeds, Breakfast cereals, Chocolate and sweets, Beverages, and Vegetables and vegetable products include most of the common foods and beverages which have medium to high antioxidant values. We find that plant-based foods are generally higher in antioxidant content than animal-based and mixed food products, with median antioxidant values of 0.88, 0.10, and 0.31 mmol 100 g, respectively. Furthermore, the 75th percentile of plant-based foods is 4.11 mmol 100 g, compared to 0.21 and 0.68...

An Optimum Nutrition Formula

Vitamins and minerals are essential for almost every function of the body. They are vital for energy and they protect you from premature ageing and degenerative diseases. And because they work together they are best digested and absorbed as natural and wholesome foods, in the context of a balanced and varied diet, not just in isolation in the form of nutritional supplements (except for the purpose of remedial therapy under the guidance of a professional nutritionist).

Treatment of Folate Deficiency

If the deficiency is nutritional it is usually treated in the first instance with dietary supplements. In the past, daily supplements of 5.0mgday_1 have been used but more recent evidence suggests that such high levels would only be appropriate for the immediate treatment of an overt deficiency. More long-term treatment would recommend dietary changes to improve folate intake. In practice, to achieve effective changes is very difficult so the recommendation might be to improve intake through foods fortified with the synthetic form of the vitamin, namely folic acid, or the use of supplements of folic acid. In both of these instances the aim is to achieve a maximum increased intake via folic acid of 400 mgday-1. Long-term ingestion of larger amounts are not recommended because of their ability to mask the diagnosis of vitamin B12 deficiencies (discussed above). Other causes of folate deficiency are treated by removing the cause, e.g., alcohol abuse.

Fluid Retention Dropsy Kidney Failure

Increasing protein consumption often relieves the body of extra fluid. Fresh parsley is an excellent kidney purifying herb. Try adding it to your salads or make parsley tea with hot water. We support heart function with low dosage, cold-processed nutritional supplements and see reduced swelling as a result. I check all patients for proper alignment of the spinal segments associated with heart and kidney function. Correction aids restoration.

Digestion and Metabolism

In achlorhydric elderly persons the absorption of calcium carbonate from a dietary supplement after an overnight fast is very poor, presumably because calcium carbonate is a relatively insoluble calcium salt and needs gastric acid to be solubilized. Again, these subjects have normal calcium absorption if the calcium is delivered in a more soluble form, such as calcium citrate. In addition to elderly persons who develop achlorhydria, a large number of people regularly use gastric acid-lowering medications, such as the gastric proton pump inhibitor omeprazole, for antiulcer therapy. These medications can reduce zinc absorption and presumably may affect the absorption of other divalent minerals. Acidification of the gastric contents and solu-bilization of minerals in the gastric juice is important because many mineral nutrients are preferentially absorbed in the duodenum (upper small intestine) and need to be available in free or low-molecular-weight complexes when they leave the stomach...

Measuring Nutrient Bioavailability in Humans

A large and growing number of people are consuming dietary supplements. However, due to the relative difficulty of labeling these supplements, in most cases, little information on the bioavailability of the nutrients in the supplements is available. A study of vitamin and mineral bioavailability from a popular multinutrient supplement found good absorption of the water-soluble vitamins (B vitamins and vitamin C) from the tablet but relatively poor absorption of copper and zinc.

Applications To Health Promotion And Disease Prevention

Generally, the nutrient and antinutritional factor (ANF) composition of seeds plays a crucial role in defining the beneficial and potentially beneficial effects of the given plant seed in human nutrition and health. Little has been published regarding the nutrient and ANF composition of DSM seeds. The proximate composition, soluble sugars, and starch contents of the seeds are summarized in Table 16.2. The seed has a high carbohydrate concentration but low protein content. As a human food resource, the soluble sugars and starch (both highly metabolizable energy sources) make DSM seeds a potential source of dietary energy. In drought years when conventional crops (cereals) fail to thrive, the highly energy dense seeds could be used to replace calories that would otherwise be derived from cereal grain. However, from a nutritional quality standpoint, the low protein content in the seed means that if there is a dependence on the seed as the staple food calorie source then supplementation...

Supplement Facts Label

To help consumers make informed choices, dietary supplements now contain a supplement facts panel that clearly labels the product as a dietary supplement and gives information such as the amount of a standard dose, the number of recommended doses per day, the list of components (and how much of each is present in a standard dose), and, if the product is a botanical, the Latin name of the plant and the part of the plant used to prepare the product. This latter information is important because the components responsible for a certain health effect may be in one part of the plant but In addition, DSHEA established standards for terms, such as high potency and antioxidant, and for the types of claims that could be made for a product. Claims that a dietary supplement may help to prevent or cure a disease cannot be made. Such claims are considered health claims and must be reviewed by the Food and Drug Administration for scientific accuracy prior to approval for use on a product label....

Selecting a CAM Modality

Selecting quality dietary supplements can be a bit more challenging. Both the natural products industry and the Food and Drug Administration are working to develop uniform standards of quality for dietary supplements. Until these standards are in place, however, consumers must be proactive in determining for themselves what supplements are consistent with their health goals and what manufacturers offer quality products. It is important not to be fooled by hype. Be wary of supplements that sound too good to be true or that promise to cure a medical condition. Quality natural ingredients and responsible product testing can add significantly to the cost of a dietary supplement. The cheapest supplement is not always the best buy, though a high price does not necessarily guarantee high quality. It is important to investigate the supplement manufacturer whose products are being considered. Manufacturer contact information appears on the supplement facts label. One should inquire whether the...

Michael Murray suggests a basic supplementation program for thyroid health. He writes I am a firm believer in building a strong foundation. In that goal, there are three key dietary supplements that I recommend to provide a strong foundation for a proper nutritional supplement plan

The American Herbal Products Association AHPA

The Botanical Safety Handbook provides safety data for more than 600 commonly sold herbs, including international regulatory status, standard dosage, and common toxicity problems. Herbs of Commerce, a reference text designed to address confusion about the common names of botanical ingredients, attempts to standardize botanical and common names for herbs. The original edition was adopted as the FDA's standard source for naming botanical ingredients on dietary supplement labels.

Biologically Based Therapies

Botanicals, Dietary Supplements, and Herbal Products. Herbs are a subset of botanicals, a term meaning plants or plant parts that are valued for their medicinal properties. Any herbal or botanical products, or phytomedicines, may be considered botanicals. In the 1994 Dietary Supplement Health and Education Act (DSHEA), Congress defined a dietary supplement as a product (other than tobacco) taken by mouth that contains a dietary ingredient, which is intended to supplement the diet. Dietary ingredients may include vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, and metabolites. Under the DSHEA, dietary supplements are considered food, not drugs, and therefore are not subject to the same oversight by the FDA that occurs with prescription drugs. Before marketing a prescription drug, manufacturers must provide the FDA with convincing evidence that the drug is safe and effective. Botanical manufacturers are not under this...

Adverse Effects And Reactions Allergies And Toxicity

Although the use of LC extracts has been documented in Chinese folk medicine, it has not been evaluated in clinical trials in an evidence-based, rigorous way. The research reports about LC are focused solely on the cell culture and mice models. The toxicity of LC extracts in mice was not found to be significantly different when using the micronucleus assay at the doses of 1.375, 2.75, 5.5, and 11 g kg, respectively (Zhong et al., 2009). Some research has indicated that LC extracts can be used as a dietary supplement without the need for establishing toxicity data in humans. For rigorous qualitative and quantitative control in modern medicine, it is apparent that we have to clarify the CMC (chemical, manufacture, and control) and toxicity data of LC extracts before the official use as a botanical drug.

Plant ingredients interfering with the sympathoadrenal system

Caffeine (and other methylxanthines, abundant in coffee and teas) inhibits cAMP phosphodiesterases, thus prolonging the half-life of cAMP, which is a critical intracellular mediator for the lipolytic and thermogenic effects of catecholamines. Ephedrine, the principle alkaloid found in shrubs of plants of the genus Ephedra, and other Ephedra alkaloids, promote the release of noradrenaline from SNS terminals and possess adrenoceptor agonist activity, thus favoring thermogenesis, vasoconstriction and increased blood pressure in addition, Ephedra alkaloids have amphetamine-like effects in the central nervous system, promoting appetite suppression, mood elevation and resistance to fatigue (reviewed in reference 162). Combinations of ephedrine and caffeine are marketed both as pure compounds in capsular form and as herbal preparations sold under the category of dietary supplements. Ephedrine and Ephedra alkaloids, alone and especially when combined with caffeine or caffeine-containing...

Other Cancer Treatments

Although there are other new and potentially helpful treatments being studied by researchers, in general, doctors and cancer treatment facilities do not accept alternative treatments. These treatments include special diets, medicines made from various plants, and vitamin supplements. The National Cancer Institute is constantly reviewing and testing alternative treatments to weigh their possible benefits against the possibility of their doing harm. Most doctors agree that trying to cure cancer with alternative therapies alone may keep patients from receiving standard treatments that have been proven effective.

Future Work Conclusions and Recommendations

N-3 fatty acids should be added to foods rather than be used solely as dietary supplements, which is a quasi-pharmaceutical approach. Furthermore, the development of a variety of n-3-rich foodstuffs would allow increased n-3 dietary intakes with little change of dietary habits. n-3 fatty acids maintain their preventative and therapeutic properties when packaged in foods other than fish. Efficient use of dietary n-3 fatty acids will require the simultaneous reduction in the food content of n-6 fatty acids and their substitution with monounsaturated oils. Dietary n-3 fats give rise to higher tissue levels of EPA when the 'background' diet is low in n-6 fats. Compared to n-6 fatty acids, olive oil increases the incorporation of n-3 fatty acids into tissues.

Folate and Neural Tube Defects

And, most importantly, the incidence of NTD by about 20 over the first years of universal fortification. Because 30 of the population takes vitamin supplements and presumably would not be expected to derive significant benefit from fortification, the actual effect may be closer to a 30 decrease due to fortification. Recent calculations suggest that, for a variety of reasons, the overall fortification amount was about twice the mandatory amount.

Relationship to HHS Common Rule and US Food and Drug Administration Human Subjects Regulations

The FDA is responsible for protecting the rights of human subjects enrolled in certain studies that investigate the use of drugs, biologics, and medical devices, as well as those that investigate foods and dietary supplements. The relevant FDA regulations require researchers to obtain informed consent from all research participants and for all research (unless otherwise exempted) to be reviewed and approved by an IRB.72 Researchers who fail to follow these requirements risk having the agency terminate the study or withhold the approval of new studies, which may ultimately result in the agency not approving the relevant drug, device, or food application.73 Moreover, an IRB or institution that fails to follow these regulations may be subject to civil or criminal proceedings and any other appropriate regulatory action.74 HIPAA's Privacy Rule does not replace the HHS or FDA regulations that is, the Common Rule applies to certain federally funded research involving living persons.

Isnt it true that the whole supplements industry is all about money

The manufacturers of nutrient supplements are no doubt in the business of making money. However, I do not believe that the motivation for the industry as a whole is entirely financial. It is clear that the nutritional supplements industry provides products to the public which often have very significant health-giving properties.

Inappropriate Nutrient Forms and Expressions

Composition tables and also on nutrition labels for both foods and dietary supplements. A more relevant unit of activity, micrograms of retinol equivalents (REs), was adopted in 1967 and has been used to set recommended nutrient intake levels. A lower relative pro-vitamin A activity of carotenoids was assumed, and thus it is not possible to directly convert IUs into REs, unless both the retinol and the carotenoid levels of a food are given. Recently, the estimated pro-vitamin activity of carotenoids has been further reduced and a newer unit proposed micrograms of retinol activity equivalents (RAEs). Again, it is not possible to convert between REs and RAEs (or between IUs and RAEs), unless the retinol and carotenoid components of a food are available. Increasingly, food composition tables are carrying separate variables for the specific forms of nutrients such as vitamin A and iron, but this is not the case for many of the older tables. Such disaggrega-tion is an obvious advantage...

Concept and Definition

The concept of functional foods derives from the observation that certain foods and beverages exert beneficial effects on human health that are not explained by their nutritional content (i.e., macronu-trients, vitamins, and minerals). The definition of functional foods varies among countries for reasons that are historical, cultural, and regulatory. In its broadest use, functional foods are food-derived products that, in addition to their nutritional value, enhance normal physiological or cognitive functions or prevent the abnormal function that underlies disease. A hierarchy of restrictions narrows the definition. In most countries, a functional food must take the form of a food or beverage, not a medication, and should be consumed the way a conventional food or beverage is consumed. If the ingredients are incorporated into pills, sachets, or other dosage forms they are considered dietary supplements or nutraceuticals, not functional foods. In Japan and Australia, the functional...

European Regulations for Functional Foods

The concept of functional foods was first evaluated in Europe in the 1990s when the International Life Sciences Institute in Europe (ILSI Europe) developed a project on functional foods that became a European Commission (EC) concerted action, Functional Food Science in Europe. Approximately 100 experts in nutrition and medicine in Europe reviewed the scientific literature about foods and food components and their effects on body functions, and they developed a global framework that included a framework for the identification and development of functional foods and for the scientific substantiation of their health-related effects. From this evaluation, two types of claims for functional foods were suggested enhanced function claims and reduction of disease risk claims. From this evaluation, the ''Concepts of Functional Foods'' was produced by ILSI followed by publication of ''Scientific Concepts of Functional Foods in Europe Consensus Document.'' According to this concept document, ''a...

Other Causes of Hyperhomocysteinemia

Other pathophysiological causes of hyperhomocys-teinemia include renal dysfunction and hypothyroid-ism. The kidney is a major site of homocysteine metabolism and renal disease leads to a significant reduction in the body's overall capacity to metabolize this amino acid. The resulting moderate to severe hyperhomocysteinemia can be attenuated, in part, by high-dose B vitamin supplements, which putatively maximize the residual renal metabolism, as well as the metabolic capacities of the extrarenal organs. Mild elevations in homocysteine occur in patients with hypothyroidism, which resolve to normal with thyroid replacement therapy. This observation implies that thyroxine and or thyroid-stimulating hormone influence homocysteine metabolism directly, perhaps through up- or downregulation of key homocysteine-metabolizing enzymes. Alternatively, homocysteine may become elevated in hypothyroid patients secondary to mild impairment of renal function that may accompany the disorder.

Introduction of Dietary Therapy

For regular infant formula or breast milk. In some clinics, only phenylalanine-free formula is given for a few days so that blood phenylalanine will quickly decrease to an acceptable level. A prescribed amount of breast milk or standard infant formula, however, should be shortly introduced into the diet. Whole protein is needed to meet phenylalanine requirements and prevent phenylalanine deficiency, which will lead to muscle protein catabolism and inadequate weight gain. For formula-fed infants, both standard infant formulas and PKU medical foods are used in prescribed amounts and are bottle fed. Breast-feeding of an infant with PKU is possible and, as with all infants, should be encouraged whenever possible. Mature breast milk contains approximately 46 mg 100ml-1of phenylalanine compared to approximately 59 mg 100 ml-1 in cows' milk protein-based formula and approximately 88 mg 100 ml-1 in soy-based formulas. Therefore, breast-fed infants may initially have slightly lower plasma...

Bone mineral density

Osteopenia may be an accumulated result of lifelong diet treatment or poor diet compliance at vulnerable stages of bone development. Compliant patients tend to have low variation in their lifelong intake of whole protein, as controlled amounts of whole protein are required to maintain good metabolic control. Compliant patients tend to have similar trends in overall intakes. Lack of adequate trace elements, whole protein, vitamins, and or minerals may be culprits. Impaired absorption of the synthetic diet or the type of medical food used (hydro-lysate versus elemental formulation) may exert an independent effect. Inadequate intakes of calcium and phosphorous are known risk factors for the development of osteoporosis in nonaffected persons. Tailoring medical foods to specifically deliver the amounts of calcium and phosphorous recommended in the new RDIs may help to prevent osteopenia.

Bioavailability Of Fortified Wheat Flour

Trace element interactions are generally antagonistic, and when two chemically similar ions are present in the intestinal lumen, the one with a greater ratio tends to exclude the other. The ingestion of excess amounts of zinc induces anemia and depresses tissue iron levels in rats and chicks (Bafundo et al., 1984), but this interaction has received little attention with regard to humans. Previous studies have reported a variety of results concerning the interactive effect of dietary minerals on the iron content of organs and tissues. NaFeEDTA is thought to be highly bioavailable, and iron in it is chelated with EDTA, a commonly used food additive that prevents the iron from being bound with phytic acid. NaFeEDTA is better absorbed and not sensitive to many food iron inhibitors compared with other iron fortificants. The lower bioavailability of elemental iron compared to that of NaFeEDTA has been confirmed (Hurrell, 2002 Viteri etal., 1995).

Type of Nutritional Support

Production (VCO2) is higher when carbohydrates are the main energy sources and lower when fat is mainly oxidised. However, patients with COPD who are in a stable clinical state usually appear to tolerate carbohydrates without difficulty. Respiratory failure has not been reported in studies of patients with COPD receiving nutritional support with enteral feeds and nutritional supplements containing up to 54 carbohydrate, but further work is needed to determine the optimal and safest feeding regimens for these patients.

Nutritional Support

Dietary supplements Although almost half of adult patients take dietary supplements, there are few published data to demonstrate their efficacy in CF. One study was unable to show any improvement in height and weight z scores when up to 30 of energy requirements were supplied by a supplement for 3 months. As a consequence, dietary supplements should be reserved for weight loss, any decline in height z score, if intake of a range of nutrients does not meet dietary reference values, or during acute chest infections. They should complement normal food intake and not replace food. In order to avoid reducing the intake of normal food, the recommended quantities are age dependent and are given in Table 3. Table 3 Recommended dosage of dietary supplements in cystic fibrosis Table 3 Recommended dosage of dietary supplements in cystic fibrosis

Dose Response Assessment

Although the data appear to indicate minimal effects from arginine supplementation at intakes up to 24.8 g d of free arginine base, the unconfirmed finding that 30 g d of arginine for 3 days resulted in a stimulation of tumor growth in breast cancer patients (Park et al., 1992) indicates that dietary supplementation with arginine is not advisable other than in at-risk children with congenital defects of argininosuccinic acid synthetase or argininosuccinase. Therefore, since neither a NOAEL nor LOAEL can be identified for intake of L-arginine from dietary supplements in healthy individuals, a UL could not be determined.

Complementary and Alternative Medicine Pain Therapies

Frequently available to people undergoing cancer treatment. Be aware that neither of these treatments should cause pain. If they do, either the person performing the treatment is not skilled enough, or the person receiving the treatment is hypersensitive and this form of therapy is not a good option for him or her. Mind-body therapies (for example meditation and hypnosis) are also often available in cancer centers. If you are considering taking dietary supplements or botanicals for any reason, including pain relief, talk to your doctor about possible side effects and drug interactions.

US Department of Commerce DOC

The DOC is the federal government department charged with promoting U.S. economic development and technological advancement. The DOC impacts the herbal industry in the United States through its involvement in international trade, import export control, and promoting access to the international pharmaceutical and nutritional supplements markets. It produces a variety of reports on the economic and business aspects of herbal commerce. Many of these are evaluations of the herbal product markets in a wide range of foreign countries, with valuable information on those countries' regulatory frameworks.

Application of Risk Assessment Methodology to Nutrients

Recent increases in demand for nutrients as a result of consumer interest in self-management of health, and provocative findings relating specific dietary constituents to possible health benefits, have provided incentives for industry to increase the availability and use of nutrients and food components in dietary supplements and for the voluntary fortification of foods. Thus, the need for science-based reviews of data on the potential for increased risk of serious adverse effects that may result from chronic consumption of individual nutrients in higher amounts than typically encountered with foods has grown in importance. Such reviews have been conducted by Canadian and US scientists through the Food and Nutrition Board, by the United Kingdom's Expert Group on Vitamins and Minerals, and by the Scientific Committee on Food of the European Commission, among others. Each has worked on developing approaches to evaluating reports of adverse effects and establishing, if possible, upper...

Evidencebased Medicine

The current trend toward EMB has ramifications for complementary and alternative medicine (CAM) remedies and techniques. Critics of CAM insist that an evidence-based medicine approach be used to establish that these therapies actually work. Federal agencies such as the National Center for Complementary and Alternative Medicine (NCCAM) and the Office of Dietary Supplements (ODS) are thus spending large sums of money to conduct clinical trials for herbal therapies, and corporate sponsorship of research is on the rise. The Cochrane Collaboration, serving as a major resource for EMB, has even established a special complementary medicine group to locate and analyze clinical trail data for CAM therapies (see entry in this chapter).

Natural Compounds Antioxidant and Antiandrogens in the Prevention of Prostate Cancer In vivo Evidences from Murine

Mouse models have significantly contributed to our understanding of PCa biology through their identification of new cancer genes and biomarkers, and their illustration of the molecular and cellular mechanisms underlying tumor initiation and progression. They have also been employed in a preclinical setting to test novel preventive and or therapeutic strategies 5,6,8-12,80 . Mice, in fact, offer several advantages. They are small, relatively inexpensive, and reproduce rapidly with large litters. More importantly, technical advances have facilitated the generation of defined genetic modifications that can also be spatially controlled, to mimic human prostate carcinogenesis. In general, and perhaps not surprisingly, a variety of phenotypes are obtained depending on the specific genetically engineered mouse model, but none exactly mimics the human disease. Although preclinical studies and the epidemiological evidence suggest that specific dietary components or nutritional supplements...

Target Nutrient Intake Possibly Achievable

The nutritionist discusses with the patient alternatives to dietary intake and the use of oral nutritional supplements that may include enteral diets taken by mouth. These supplements include liquid formula diets as well as specific supplements (e.g., potassium, magnesium, calcium, zinc, and vitamins). If during a trial period there is progressive improvement in intake or the patient meets the target, this process is continued. If the patient cannot meet the target or is clearly unable to progress toward it, then formal EN is started.

Hydroxycitric acid 1031 Background

Wild but is also cultivated in some areas. The fruits of G. cambogia are about the size of an orange but resemble a small yellowish or reddish pumpkin. The dried rinds of the fruit are used in food preparation in several Southeast Asian countries where, amongst other attributes, they are said to be effective in making meals 'more filling' (FDA, 2005a). Good use of this feature of G. cambogia has been made by the dietary supplement industry, particularly in the USA where supplements containing Garcinia extract have been promoted for appetite suppression for many years.

Risk Characterization

Since there is no evidence that amino acids derived from usual or even high intakes of protein from food present any risk, attention was focused on intakes of the L-form of the amino acid found in dietary protein and amino acid supplements. Even from well-studied amino acids, adequate dose-response data from human or animal studies on which to base a UL were not available, but this does not mean that there is no potential for adverse effects resulting from high intakes of amino acids from dietary supplements. Since data on the adverse effects of high levels of amino acids intakes from dietary supplements are limited, caution may be warranted.

Summary and Recommendations

Across the literature reviewed, adherence has emerged as an issue taking predominance over dietary content itself. Regardless of diet, the greatest weight loss is associated with duration of and adherence to the protocol. If adherence is the key factor, then Bal diets seem to be the best recommendation. In addition, these appear to produce no adverse effects and, unlike both Low-Cho and Low-Fat diets, require no extraneous vitamin supplements. Bal diets seem to constitute a moderate and healthful approach in which all food groups are represented and nutritional adequacy is met. A self-help book that encompasses this approach is Brownell's (2004) LEARN program. Interestingly enough, it ranks 285,607th among sales on Amazon.com. Clearly it is not the first choice of consumers looking for a way to lose weight.

Safety and regulatory status

As noted above, G. cambogia extract HCA has been a component of dietary supplements in the USA for some years. In 2003 InterHealth announced that a panel of scientific experts had affirmed Super CitriMax as GRAS (generally recognized as safe) for use in functional beverages in the USA (Interhealth website, GRAS affirmation). This is the first step towards more general food application of HCA. It seems likely that if HCA becomes a mainstream ingredient raw material supply might become an issue. This has obviously been predicted by the Ireland-based Company, Shannon Minerals Ltd, who recently submitted a premarket notification of intention to market synthetic HCA as a new dietary ingredient for dietary supplement applications. The FDA rejected this application, unconvinced of equivalence to the currently marketed HCA extracted from G. cambogia.

Dietary Guidelines for Health Function and Disease Prevention

Robert Russell and colleagues constructed a food guidelines pyramid, which specifically focused on the health of the elderly. Among the elements and tenets that differed from the standard US pyramid are the following recommendations to drink additional water and liquid to increase consumption of dietary fiber and to consider dietary supplements such as calcium and vitamin E. Otherwise, selecting the same requisite serving portions of the specific food groups, and avoiding excess sugar, salt, and separated fats as indicated by the conventional guidelines emblem is recommended for the older population as well.

The FTC Bureau of Consumer Protection

The FTC is the U.S. government agency responsible for monitoring business practices in the United States. Its duties include enforcing antitrust laws to ensure that competition is fair, preventing false and deceptive advertising, regulating labeling and packaging, and gathering data concerning business conditions. In addition to its enforcement responsibilities, it is also mandated to advance congressional policies through cost-effective nonenforcement activities, such as consumer education. The FDA and the FTC share jurisdiction over the regulation of dietary supplements whereas the FDA oversees labeling requirements, the FTC regulates other aspects of advertising and has the power to order a business to cease and desist using an advertisement found to be deceptive.

Dietary Sources and High Intakes

Pantothenate is widely distributed in food rich sources include animal tissues, especially liver, and yeast, with moderate amounts occurring in whole grain cereals and legumes (see Table 1). It is fairly stable during cooking and storage, although some destruction occurs at high temperatures and at pH values below 5 or above 7. Highly processed foods have lower contents than fresh foods. Commercial vitamin supplements containing pantothenate usually contain the calcium salt, which is crystalline and more stable than the acid.

Metabolicthermogenic Effects

Ephedra is promoted as a ''fat burner'' or thermogenic agent because of its reported effectiveness in increasing basal metabolic rate and contributing to weight loss. Several small studies have documented that the combination of ephedrine and caffeine increases oxygen consumption and lipid oxidation, raises resting energy expenditure (REE), and promotes weight loss (51-54). In contrast, there is no experimental evidence that caffeine or ephedrine alone is more effective than placebo in producing weight loss, despite demonstrated increased thermogenesis of the individual agents (55,56). Studies involving ephedra- and caffeine-containing dietary supplements have also shown modest weight loss compared to placebo (30,31).

Impact of Supplementation

Numerous investigators have explored the benefits of energy and or protein supplementation for pregnancy weight gain and other outcomes. However, relatively few trials have randomly assigned these supplements and used control diets. A statistical analysis was conducted of the 10 such studies that met this criterion in 1995. Most, but not all, of these studies were performed in developing countries. A 5-year controlled trial in The Gambia provided daily prenatal dietary supplements (two biscuits) that contained 4250 kJ energy and 22 g protein. This supplement increased pregnancy weight gain and birth weight during the hungry and harvest seasons. There was a significant but very small increase in head circumference and a significant reduction in perinatal mortality.

Regulations Related to Functional Foods

Functional foods are regulated by the United States Food and Drug Administration (FDA) under the authority of two laws. The Federal Food, Drug, and Cosmetic Act (FD& C) of 1938 provides for the regulation of all foods and food additives. The Dietary Supplement Health and Education Act (DSHEA) of 1994 amended the FD& C Act to cover dietary supplements and ingredients of dietary supplements. Functional foods may be categorized as whole foods, enriched foods, fortified foods, or enhanced foods. Labeling claims that are used on functional foods are of two types (1) Structure and function claims, which describe effects on normal functioning of the body, but not claims that the food can treat, diagnose, prevent, or cure a disease

Read The Label Carefully And Dont Believe Everything You Hear

Many people assume that physicians are automatically against anything they did not prescribe. Literature on alternative medicine may even contain a statement such as Doctors are not going to give you this because it will cure you. Then you will not have to go back and they will not make any money. Nothing could be further from the truth. If peanut butter from the supermarket cured arthritis, I'd be thrilled to send my patients straight to the checkout counter. In the sections that follow, I discuss vitamin and mineral supplementation, alternative diets, dietary supplements, and herbal cures. Some I favor others I oppose.

Dietary Selenium Absorption and Mechanisms of Incorporation of Selenium into Selenoproteins

Figure 1 summarizes the main pathways of interconversion of selenium in mammalian tissues. Selenium appears not to be an essential element for plants, but it is normally taken up readily into their tissues and is substituted in place of sulfur, forming the seleno-amino acids selenomethionine and selenocysteine, which are then incorporated at random in place of the corresponding sulfur amino acids into plant proteins. All branches of the animal kingdom handle selenium in essentially similar ways. When ingested, plant selenium-containing proteins liberate free seleno-methionine and selenocysteine, either for incorporation at random into animal proteins or for metabolic turnover, to liberate inorganic selenide, which is the precursor of active selenium to be inserted at the active site(s) of the selenoproteins. Selenide is also supplied by the reduction of selenite and selenate that enters the diet from nonorganic sources (i.e., from the environment) or from dietary supplements of...

Cocaine Behavioral Approaches No

Consensus exists about how to treat Cocaine dependence. This statement is particularly alarming given that in 1998 it was estimated that 1.8 million persons in the United States were dependent on cocaine. The abuse of cocaine was first recognized in the medical literature in the late 1800s. Early proposed treatments included various herbal and medical potions, nutritional supplements, hot baths, substitution of Morphine, long stays in sanatoriums, education, and psychotherapy. Systematic evaluation of the effectiveness of these early treatments did not occur.

Omega3 and other polyunsaturated fatty acids in functional food products

Functional foods are food products that have beneficial effects on physiology and or have the ability to reduce the risk of a disease. Functional foods may be conventional food or foods that have been enriched with functional components to provide greater health benefits, but they do not include purified substances provided in pills or capsules. Since omega-3 PUFAs have been shown to have beneficial effects in several health conditions they are considered to be a functional food. The positive effects of omega-3 PUFAs in different diseases have been established and these fatty acids have been particularly interesting in coronary heart disease but also in several other conditions such as arteriosclerosis, type 2 diabetes, cancer, depression and asthma (de Lorgeril et al., 1994 Simopoulos, 1999 Ruxton et al., 2004 Nettleton and Katz, 2005). The beneficial effects of omega-3 PUFAs on health have resulted in the production of dietary supplements becoming a large industry. There is also a...

How Is the Sales Data Derived

Global sales have been estimated to be between 70 billion and 250 billion. This approximately 3-fold difference in estimates is due to the variation in what products are actually included in product sales results. As will be discussed, the definition of dietary supplements varies greatly from country to country therefore, deriving sales data is complex. Another difficulty in assessing sales of dietary supplements is the source from which sales data are gathered. Many business surveys rely on only one or two of the following sales outlets to derive their results

Prevalence of Micronutrient Supplement

In the United States, vitamins and minerals are the most widely used dietary supplements. Between 1993 and 2003, total retail sales of vitamins and minerals more than doubled, increasing from approximately 3 billion to 6.7 billion for vitamins and from approximately 0.6 billion to 1.8 billion for minerals. These figures include sales of multivitamin and multimineral combinations as well as individual vitamins and minerals. Multivitamin mineral preparations, accounting for almost half of micronutrient purchases, consistently have been the best-selling micronutrient supplements, with sales increasing from 2.64 billion in 1997 to 3.68 billion in 2003. Findings by several research groups show that micronutrient supplement use generally is more common among people with higher education levels, higher incomes, and better diets. Survey results in The Netherlands indicate that micronutrient supplements are used by approximately 20 of adults in that country, fewer than in the United States....

Research Approach for Determining the Health Impact of Micronutrient Supplements

Clinical trial, which is designed to eliminate all possible bias, is considered to be the gold standard of scientific intervention research. In such trials, some people receive the substance being tested (e.g., drug, micronutrient, or other dietary constituent) and some receive an inactive placebo. These trials may not be possible in all circumstances, however, because of ethical issues that make it inappropriate to withhold the substance being tested from any trial participants. For example, now that it is established that low periconceptual folate intake by women is linked to NTDs, a placebo-controlled intervention trial to test the minimum effective supplemental amount would be unethical. In such cases, all available evidence from in vitro laboratory research and in vivo animal studies, as well as epidemiologic studies and surveys, must be reviewed systematically and objectively to draw conclusions about the possible effectiveness and safety of the substance of interest and to make...

Vegetarian Eating Patterns

Numerous restrictions generally including avoidance of all meat, poultry, milk and eggs, but may consume fish in small amounts. Also avoid sugar and other refined sweeteners, foods that are members of the nightshade family (peppers, egg plant, tomatoes, and potatoes) and tropical fruits. Current variations of the diet are less restrictive than the versions of 30years ago, but deficiencies of energy, iron, calcium, vitamin B12, vitamin D, and other nutrients may still arise in weanlings, pregnant women, and young children if diets are nutritionally unplanned Avoidances include all animal products including meat, fish, poultry, eggs, and dairy products. Some vegans may also refuse to use any animal products in daily life. Without careful planning, energy, vitamins B12 and D, and bioavailable sources of iron may be low. Concentrated sources of energy-dense foods such as sugars and fats are helpful in increasing energy intakes. Vitamins B12 and D and calcium can be supplied from fortified...

Current Vegetarian Eating Patterns and Practices

At the same time, vegetarian eating patterns are much more heterogeneous today than in the past. The availability and variety of plant foods, as well as commercially available and tasty meat analogs has greatly increased. Fortified foods today include soy milks fortified with vitamins B12 and D and a highly bioavailable form of calcium, and highly fortified breakfast cereals. These foods and nutrient-containing dietary supplements make it easier for vegans and vegetarians to obtain nutrients that would otherwise be low or lacking.

Presentday Cultivation And Usage

Sunflower seeds are used for the production of SO, which is a very useful dietary supplement, being enriched in fatty acids and used as an ingredient in many pharmaceutical preparations. Seeds can be sprinkled over cereals, salads, and soups, and mixed with vegetables and snacks. The seeds are diuretic and expectorant, and are now highly valued for the treatment of bronchial, laryngeal and pulmonary infections, coughs, and colds. They are also used to reduce the risk of colon cancer, the severity of hot flushes in women going through menopause, and also diabetic complications. They are also prescribed for snake bite and scorpion sting. Sunflower seed oil is used internally to alleviate constipation, as a lubricant, and is used externally as a massage oil, an oil dressing, and in the treatment of skin lesions, psoriasis, and rheumatism. The oil-cake is a valuable food for cattle and poultry (Bruneton, 1999 The Wealth of India, 2001 LaGow, 2004 Chopra et al., 2006). The oil is used in...

Vitamin E Status and Requirements

It has been suggested that the optimum concentration of a-tocopherol in plasma for protection against cardiovascular disease and cancer is > 30 mmoll-1, given normal plasma lipid levels and in conjunction with a plasma vitamin C concentration > 50 mmoll-1 and a -carotene level > 0.4 mmoll-1. This has not been proven in large-scale human intervention trials, but even in the absence of conclusive evidence for a prophylactic effect of vitamin E on chronic disease prevention, some experts believe that a recommendation of a daily intake of 87-100 mg a-tocopherol is justifiable based on current evidence. Realistically, these levels can be achieved only by using nutritional supplements. The tolerable upper intake level for vitamin E is 1000 mg day-1, based on studies showing hemorrhagic toxicity in rats, in the absence of human dose-response data.

Antihypertensive Actions of Vitamin B6

A number of studies suggest that supplements of vitamin B6 may have a hypotensive action. Supplements of 300 mg of vitamin B6 per kg of body weight per day attenuated the hypertensive response of rats treated with deoxycor-ticosterone acetate (Fregly and Cade, 1995). At a more realistic level of supplementation (five times the usual amount provided in the diet), vitamin B6 prevented the development of hypertension in the Zucker (fa fa) obese rat. Withdrawal of the vitamin supplement led to the development of hypertension (Lalet al., 1996).

Hydroxymethylbutyrate

Beta-hydroxy-beta-methylbutyrate (HMB) is a leucine metabolite that has shown anticatabolic actions through inhibiting ubiquitin-proteosome-mediated protein breakdown216 and that may prevent exercise-induced muscle damage.217 It is primarily used by bodybuilders as a supportive measure to induce changes in body composition, and could be a potential dietary supplement for body weight reduction.182 Randomized clinical trials conducted to assess the potential for HMB as an ergogenic aid reported modest effects in reducing fat mass and increasing lean body mass, and no apparent adverse effects (reviewed in references 199 and 218).

Enzyme Induction by Biotin

Glucokinase is the high-_RTm isoenzyme of hexokinase found in liver and pancreatic f-islet cells. In the liver, its function is to permit rapid uptake and metabolism of glucose when the concentration of glucose in the portal blood is high after a meal. In the pancreas, the increased uptake and metabolism of glucose caused by glucokinase acts as the signal for insulin release. Children with a genetic lack of glucokinase suffer from what has been termed maturity-onset diabetes of the young (MODY) although they can synthesize and secrete normal basal amounts of insulin, they are unable to secrete additional insulin in response to glucose (Froguel et al., 1993). Presumably as a result of increased activity of glucokinase, high doses of biotin have a hypoglycemic effect in insulin-dependent diabetic patients. In non-insulin-dependent spontaneously diabetic mice, the administration of 2 mg of biotin per kg of body weight (considerably in excess of vitamin requirements) lowers blood glucose...

Europe And Germanys Commission E Monographs

Government agencies in North America and in several European countries are currently trying to develop a regulatory framework that would satisfy health professionals, consumers, and the herbal industry. Recent developments in North America include the establishment of the Office of Dietary Supplements (ODS) in the United States and the Office of Natural Health Products (ONHP) in Canada.

Hypervitaminosis A and Vitamin A Toxicity

Beta-carotene and other carotenoids in foods, even when consumed at high levels, are believed to be nontoxic, and therefore no UL was established for -carotene. Nonetheless, a 'safe range' of intracellular -carotene has yet to be determined. Individuals who have consumed large amounts of carotenoid-rich foods, juices, or extracts containing a large amount of -carotene over a prolonged period of time may show signs of carotene accumulation in fatty tissues, to the point where yellowing of the skin (caroteno-dermia) is apparent. This condition is not known to be harmful and the color subsides over time after carotene intake is reduced to normal levels. Nonetheless, epidemiological evidence suggests that the use of high-dose -carotene as a dietary supplement should not be regarded as safe because the current knowledge of the metabolism of high doses is inadequate, and some epidemiological studies have indicated that high doses of -carotene, at least in smokers, may be detrimental (see...

Toxicity of Vitamin B6

In 1983, sensory neuropathy was reported in seven patients who had been taking between 2,000 to 7,000 mg of pyridoxine day for several months (Schaumburg et al., 1983). On withdrawal of the vitamin supplements, there was considerable recovery of neuronal function, although there was residual nerve damage in some patients. 9.6.4.1 Upper Levels of Vitamin B6 Intake Although there is no doubt that vitamin B6 is neurotoxic in gross excess, there is considerable controversy over the way in which toxicological data have been translated into limits on the amounts that may be sold freely as nutritional supplements. This appears to have been achieved by the application of standard toxicology safety margins, and taking as the upper safe limit of intake 1 of the no adverse effect level. Whereas this is appropriate for setting limits on additives and contaminants, it can be argued that it is not appropriate as a basis for setting limits on a nutrient for many nutrients, an upper limit of intake...

Point by point how do you answer charges that

Vitamin E is a natural blood thinner, which in part accounts for its beneficial effect in the prevention and treatment of heart disease. Certain medications, notably warfarin, also thin the blood and this effect may be enhanced too far by the additional taking of vitamin E. For this reason it is generally advised that individuals on warfarin or other anti-coagulant medication do not take vitamin E. If you are receiving medication for any health problem you should always check with your doctor before taking nutritional supplements (or any other dietary change) in case there is such a contra-indication.

Neurocutaneous syndromes

Folic acid is found naturally in green, leafy vegetables and in orange juice. In 1998 the U.S. Food and Drug Administration required the addition of folic acid to enriched grain products (such as breakfast cereals, breads, pastas, and rice), designed to provide an additional 100 micrograms of folic acid to a woman's daily diet. Still, to reach the recommended level of 400 micrograms daily, a vitamin supplement is usually necessary.

Types of CAM Modalities

Mind-body interventions recognize the connection between the physical body and the spiritual self, and include practices such as meditation, prayer, and music therapy. Biologically-based modalities are primarily nutrition-related and vary from special diets such as the macrobiotic diet to the inclusion of dietary supplements in the diet. Body-based methods involve hands-on manipulation of the body, and include such modalities as massage and chiropractic. The energy therapies are based on the concept that the body has an energy field that can be manipulated to promote healing. Included among the nutrition approaches that make up the biologically-based modalities is the use of dietary supplements. Dietary supplements may be botanical (herbal) supplements or nutritional supplements, which include vitamins, minerals, antioxidants, enzymes, metabolites, nonpre-scription hormones, glandular extracts, and various amino acids, fatty acids, and other nutrients.

Dietary and Nutritional Management of Secondary Undernutrition

In juvenile cholestasis, large amounts of fat-soluble vitamin supplements and medium-chain triglycerides are usually required for optimum growth. With protracted secretory diarrheal diatheses, fluid and electrolyte balance may be the primary concern, followed by macro- and micronutrient nutriture, invoking the institution of parenteral feeding. Cancer cachexia is a major secondary consequence of disseminated neoplasms. It is tempting to prescribe aggressive nutritional support, but a caveat is that certain nutrients acting with certain neoplasms favor the tumor's growth and dissemination. To the extent that various forms of cachexia are partly driven by catabolic responses mediated by proinflammatory cytokines, antagonists directed at counteracting their action hold promise for retarding the nutrient-wasting in various forms of cachexia.

Tocopherols and Cardiovascular Disease Epidemiological Evidence

87245 women, showed a 34 reduction in CHD in women who had consumed vitamin E supplements containing more than 67 mg a-TE daily for more than 2 years. However, there was no significant effect of vitamin E obtained from food sources. The Established Populations for Epidemiolodic Studies of the Elderly (EPESE) trials showed that the use of vitamin E supplements significantly decreased risks for all-cause-mortality and mortality from heart disease. Another prospective study, performed in Canada, reported a consistent inverse association between CVD and vitamin E supplement usage. The Health Professionals Study, conducted on 39 910 men aged 40-75 years, also showed that dietary intakes of vitamin E were not significantly correlated with reduced risk of CHD or death. A protective effect was seen in those who took 67-160 mg supplemental a-TE daily for more than 2 years. In contrast, the Iowa Women's Health Study reported that dietary vitamin E (mainly 7-tocopherol) was inversely associated...

The Longwood Herbal Task Force LHTF

The LHTF was founded in the fall of 1998 by faculty, staff, and students from Children's Hospital, the Massachusetts College of Pharmacy and Health Sciences, and the Dana Farber Cancer Institute. Its mission is to help educate clinicians about the use of herbal remedies and other dietary supplements. The LHTF has comprehensive collections of fact sheets on herbs for both patients and their health care providers. Documents are available for the more popular herbs, such as echinacea and St. John's wort, but also for lesser-known herbs, such as rhubarb (Rheum officinale), dandelion (Taraxacum officinalis), and bearberry (Uva ursi). Information on herb-drug and herb-nutrient interactions is also available.

Toxins and Contaminants Phytic Acid
