Throughout this century food guide systems (Five Food Groups, Basic Seven, Basic Four, Food Guide Pyramid) have dramatically changed and with the changes the need for adequate assessment measures has changed as well. The objective of the study was to develop and validate two such rapid assessment methods that could possibly be employed as educational devices in nutrition education programs while taking away the need for expensive computer analysis and/or the time consuming, inefficient, and often tedious job of nutrient assessment through various tables of food analysis and composition.

College students aged 18-24 served as the sample population and their three-day dietary recalls the data for this study. Each diet was compared to the Food Guide Pyramid (FGP) by using one rapid assessment method scored in two ways (FGP₁ and FGP₂). FGP₁ is a simple point-far-point method based on minimum recommended servings from the Food Guide Pyramid and the FGP₂ score is a weighted method of food groups based on the same criteria. All diets were evaluated in terms of nutrient quantity by computer analysis and translated into mean adequacy ratios for fourteen nutrients (MAR₁) and for seven problem nutrients (MAR₂). The FGP scores (FGP₁ and FGP₂) were then compared to each of the MAR scores (MAR₁ and MAR₂) to test validity by correlation analysis. Results indicate both rapid assessment tools maintain significant correlation (p<000.1) with actual nutrient intakes. A mean FGP₁ score of 10.8 (max. = 15) correlated significantly with a mean MAR₁ score of 0.88 (max. = 1.00)(r = 0.68) and with the MAR₂ score for problem nutrients of 0.83 (max. = 1.00)(r = 0.66). A mean FGP₂ score of 21.3 (max. = 30) correlated significantly with a mean MAR₁ score of 0.88 (max. = 1.00)(r = 0.65) and with the MAR₂ score for problem nutrients of 0.83 (max. = 1.00)(r = 0.63). Results illustrate that the FGP₁ score could be used by the general public individually and in nutrition education programs to help assess diets based on nutrient adequacy.
