Explain the Expanding Frontiers of Nutrition?
While the essential nutrients mentioned in Table are indispensable and our diets need to provide them all in adequate quantities, it has become clear that for healthy living they are not by themselves enough. Other dietary constituents, such as the phyto-chemicals and anti oxidant substances, are equally important. A deficiency of these may not produce overt recognizable symptoms but they are nevertheless known to play an important role in prevention of degenerative diseases, delaying the adverse and often considered as inevitable consequences of ageing like cataracts, blunted memory and in fie the detoxification of waste materials or environmental pollutants. Tile present data is sufficient to include these as essential dietary components but what is lacking is the information concerning the amounts of these compounds that we need to consume in our daily diet.
