An index number that described the nutrient adequacy of a diet was estimated from a simple regression equation developed from dietary information provided by a group of pregnant women. A small number of foods provided sufficient information to estimate nutrient adequacy of diets with an efficiency of from 79 to 85 percent. The simple index number was generated by multiplying number of servings from either three or four food groups by appropriate regression coefficients. Equations generated for a specific population group were shown to have high reliability since similar index numbers (r = 0.962-0.992) were obtained when dietary data obtained during this study were inserted into an equation generated during a prior study. Results from this study suggest that simple regression equations can be generated from a specific population group and subse quently be used to assess nutrient adequacy of diets for comparable groups.
