Use of the food guide pyramid to improve dietary intake and reduce cardiovascular risk in active duty air force members

Abstract

Abstract : The goal of this study was to determine if adherence to the Food Guide Pyramid guidelines, when combined with exercise, results in significant reductions in cardiovascular risk and enhancement in aerobic capacity (VO2 max) when compared to a regimen of exercise therapy alone. Twenty men and twelve women, mean age=32, with similar baseline V02max, total cholesterol (TC), low density lipoprotein (LDL), body mass index (BMI), and dietary fat intakes were randomized into two groups. All subjects participated in a 90-day fitness improvement program. One-half of the subjects (treatment group), received weekly, individualized dietary counseling using the Food Guide Pyramid as an educational tool. All participants completed a food frequency questionnaire at baseline and post-treatment.
