The new significance attached to food as an implement of war as well as peace has served to stress the fact that nutritional quality must be considered along with yield, appearance, and other factors in evaluating the importance of a food crop and its priority in a food production program. At a time when the food supplies for the armed forces, lend-lease shipments, and rehabilitation work are being allocated on the basis of their nutritive value, when nutrition programs for industrial workers are being established, and when throughout the country Victory Gardens are producing a variety of crops for home consumption, the conservation of nutritive values of foods assumes equal importance with the production of foods of the highest possible inherent nutritive value.
