Abstract :

T he very nature of food imparts its unique chemical composition. The majority of these chemical compositions have yet to be characterized. This is especially difficult since food is heterogeneous or varies in its natural state and simply cannot meet the same rigorous standards for uniformity and purity as other manufactured items. Nutritional research has focused for years on understanding the effects of vitamins and minerals (micronutrients) found in foods and needed by our bodies for survival. A micronutrient deficiency can and will lead to a loss of partial or total function of one or more bodily processes, organs or systems. Eventually, when our body can no longer make up for the deficiency, disease will develop. Since deficiency of the required micronutrients will lead to toxic effects or disease, it is significant to nutritional toxicologists, food scientists and clinicians to gain an understanding of how these micronutrients play a part in the thousands of processes in our body. There are very few nutrients that are found in natural food sources that will cause significant toxicity, with the exception of Vitamin A, Vitamin D and some other minerals. Potential sources of toxicity from nutrients generally come from dietary supplements. While dietary supplementation has long been used clinically, particularly with blood anemia and pre-natal patients, if these supplements are taken in too high doses, toxic effects can occur
