This survey was conducted to evaluate with 457 health professionals from July, 1999 to September, 1999 the awareness of and satisfaction with the nutrition labeling system in Korea and to determine a desirable labeling system. Professors of food and nutrition and nutrition researchers in the food industry had the hightest scores on awareness of the nutrition labeling system(75.6% and 73.4%, respectively), which was significantly different from each other by occupation(p < 0.01). Frequently checked labeling information were expiration date, production date, price, and company respectively. Special nutrient food producers(56.9%), dietitians(49.3%), nurses(48.1%), researchers(42.3%) answered moderately on satisfaction with nutrition information for products, which was statistically significant(p < 0.01). This suggests that health professionals were unsatisfied with the present nutrition labeling system. In nutrition focusing statements, nutrient content claims, health claims, and working periods were significantly related with nutrition focusing statements and health claims, but not with nutrient content claims : the subject who had been working for more than 10 years and less than 5 years had positive thoughts or those matters while the subjects whose working periods were between 10 and 5 years had the lowest score. The most desirable labeling units were serving size(65.1%). Ninety two percent of the subjects wanted absolute nutrient contents in food and their percentage of the KRDA. Eight nine percent of health professionals agreed that the health claims should be used only with scientific approval by the government or food research institutions. Only 4.4% of subjects were satisfied with current regulations of health claims(p < 0.001). More studies regarding labeling units, their range and nutrient reference values are needed. The opinions of health professionals in nutrition labeling system should discussed to establish a desirable nutrition labeling system.
