  • Title: Nutritional implications of dietary phytochemicals.
    Author: Messina M, Messina V.
    Journal: Adv Exp Med Biol; 1996; 401():207-12. PubMed ID: 8886139.
    Abstract:
    Although increasing the levels of phytochemicals in foods via traditional breeding or genetic engineering would appear to pose less of a risk, there is still the possibility of over consumption given the ease with which phytochemical content can be increased. According to the recent position paper by the American Dietetic Association on phytochemicals, "the dietetics professional ... is the specialist who should make recommendations concerning appropriate dietary intake to optimize the potential benefits of phytochemical-rich or functional foods in overall health." For dietitians to make these recommendations, it will be necessary for the nutrition community to make a concerted effort to incorporate information on phytochemicals into nutrition manuals and professional resources. As it is, most of the research and discussion of phytochemicals is conducted by professionals not related or only peripherally related to the field of nutrition. This is truly an exciting time to be involved in the nutrition field. We have moved a head from thinking that only a relatively small number of dietary factors possess biological activity to recognizing that there are hundreds and perhaps thousands of such factors. It will be many years before our understanding of phytochemicals approaches our knowledge of vitamins and minerals- and it is worth nothing that our knowledge of vitamins and minerals is still incomplete. But it does appear that the phytochemicals help explain why plant-based diets, in general, are associated with a reduced risk of many chronic diseases. And in fact, his may be the most important outcome from use of phytochemicals. The nutrition community now has more reasons for encouraging consumers to eat plant-based diets.
