TO DETERMINE SATIETY INDEX OF LOW-FAT YOGURT COMPARED TO BREAD IN HEALTHY ADULTS

Background and Aim: The aim of this study was to determine satiety index of low-fat yogurt (1/5%) in healthy adults with normal body mass index.Methods: This semi-experimental study was conducted on 30 healthy adults with normal body mass index for two consecutive days. In the first day, each participant consumed 90 grams white bread and in the second day 526 grams 1/5% low-fat yogurt within 15 minutes. We evaluated the satiety of low-fat yogurt and white bread based on VAS and LIKERT scales. Anthropometric indices were measured. We evaluated food intakes by food record and physical activity by physical activity record in night before each test. Cronbach s alpha was 0.98 for satiety of white bread and 0.947 for low-fat yogurtResults: Satiety index (SI) of low-fat yogurt was 136/66 ± 1/46 compared to white bread (with SI of 100). The changes of satiety 120 minutes after consumption of white bread and low-fat yogurt were not significant based on the VAS scale, but according to the LIKERT scale low-fat yogurt changes showed significant increase (mean ± SD) (changes=1/60 ± 0/43) (p=0/03). The hungry of people was equal 1/66 units. Conclusion: The satiety index of low-fat yogurt in adults with normal body weight was 136/66 % compared to white bread that showed higher satiety of low-fat yogurt compared to white bread. Amount of satiety according to the LIKERT scale 120 minutes after consumption of low-fat yogurt than the beginning showed significant increase. This suggested method can be used for determination of SI of other foods in Iranian population.
