The program of the recent IX International Congress of Nutrition held
in Mexico City, September 3-9, 1972 provides a vivid illustration of the
progress and ever-expanding scope of nutrition as a basic science and an
invaluable instrument for social betterment. It has now become increasingly
evident that progress in the development of new foods for the battle
against hunger depends in large measure on new concepts of nutritional
biochemistry. Namely, the practical and basic problems should be considered
and explored in terms of molecular nutrition. The biological contributions
of each nutrient must now be evaluated in reference not only
in terms of its own biochemical interactions but also in relation to its
effects on the metabolites of all other nutrients and daily biological
rhythms. In this volume an effort has been made to review some recently
developed methods—method defined as a manner or mode of procedure—
that may be expected to have a telling impact on the future progress of
the science of nutrition.
