Importance of Nutrient Bioavailability to Human Nutrition

Assessment of bioavailability of nutrients is an essential component of deriving dietary reference intakes (DRIs), guidelines for optimal intake of individual nutrients established for North American populations. Many DRIs are based on evaluation of available physiological data to determine the obligatory daily needs for a nutrient to replace losses, or the amount needed for optimal growth of tissues, and an estimate of overall dietary bioavailability of the nutrient in question. In many populations, the content of a nutrient in the diet (e.g., iron or zinc) may be sufficient to meet recommended intake, but bioavailability is suboptimal due to the presence of high levels of inhibitory substances (such as phytate) in the diet leading to a high risk of developing this nutrient deficiency.
