Three groups of subjects--49 dietitians, 44 university nutrition students and 67 of the general public— were surveyed by questionnaire to determine if a relationship existed between use of food supplements and level of nutrition knowledge. The questionnaire contained a 40-question nutrition knowledge test. Dietitians received a mean score of 33.1, followed by the students with a mean of 26.2 and the general public at 24.7. Use of supplements within the last two years was reported by 39 (79.6%) of the dietitians, 34 (77.3%) of the nutrition students and 60 (89.5%) of the geneal public. Calcium was the most frequently consumed supplement among the dietitians and the general public. Multivitamins were favored by the students. Dietitians consumed supplements mainly for nutritional insurance. Student practices and attitudes were similar to those of the general public rather than to those of the dietitians. Both groups consumed supplements for "nutritional insurance," but also "to prevent colds and illness." "For energy" was also a popular reason for supplement use with general public sujects.
