A Study Evaluating Nutrient Intake and Diet Quality in Female College Students According to Coffee Consumption

ABSTRACT

The purpose of this study was to assess nutrient intake and dietary quality in female college students according to their coffee consumption. The survey was conducted through questionnaires and 3-day dietary records with 353 students. The subjects were divided into three groups students who didn't consume coffee (non-coffee group, N=119), students who consumed or = 250 ml coffee (moderate-coffee group, N=94). There were no significant differences in age, weight, height, and BMI among the three groups. The mean daily energy intake was 1800.8 kcal in the non-coffee group, 1724.9 kcal in the light-coffee group, and 1729.7 kcal in the moderate-coffee group. The moderate-coffee group consumed a significantly higher amount of alcohol than the light-coffee group (p <0.05). The average intakes of dietary fiber, vitamin A, beta-carotene, and folate in the non-coffee group were significantly higher than those in the light-coffee and moderate-coffee groups. Indexes of Nutritional Quality (INQ) for vitamin A, niacin, and vitamin B6 were significantly higher in the non-coffee group than in the light-coffee group. Also the non-coffee group consumed a significantly higher amount of vegetables compared to the light-coffee group. There was no significant difference in the Dietary Diversity Scores (DDS) among the three groups. These results suggest that coffee consumption affects food and nutrient intake in female college students.
