Dietary habits of first-year medical students assessed during clinical nutrition course.

To enhance the Introduction to Clinical Nutrition course at the University of Alabama at Birmingham, medical students taking the course from 1989 to 1992 (n = 616) were required to analyze by computer the nutrient composition of their own diets for a 24-h period. In 1991 and 1992, they were required to repeat the analysis at the completion of the course. Overall, fat comprised 30% of energy intake, and along with saturated fat and the cholesterol-saturated fat index, it declined virtually each year compared with the previous year. Significant changes were noted by the end of the course in 1991 and 1992 compared with the beginning, when fat comprised 26% of energy, and more students adhered to recommendations for dietary fat, saturated fat, and fiber. Vitamin C intakes exceeded the recommended dietary allowance by more than twofold and increased further by the end of the course in 1991 and 1992, probably indicating an increase in fruit and vegetable intake. Each year, most students rated the dietary assessment as moderately or very useful. These data suggest that dietary self-assessment is a useful tool for teaching clinical nutrition in medical schools and that, even before instruction in clinical nutrition, medical students are favorably altering their dietary patterns to a greater extent than the general population.
