Expressing the nutrient composition of foods and diets, and the human dietary allowances for individual nutrients, on the same basis--nutrients per 1,000 kcal--allows direct comparisons and quality judgments. A 1,000 kcal portion of whole milk contains 54 grams of protein, whereas 25 grams is the suggested allowance per 1,000 kcal. An "Index of Nutritional Quality" can be derived from the ratio; for milk protein it would be 54/25 or 2.2. This ratio, which is dependent of serving size, allows easy assessment of food supplies or combinations vis-a-vis dietary allowances and calories provided. First, the Recommended Dietary Allowance must be converted into an allowance per 1,000 kcal to obtain a single-value allowance for each nutrient. The method is described and a table is presented of the converted figures by age and sex group for energy, fat-soluble vitamins, water-soluble vitamins, and minerals. Wide use of this approach is recommended
