Potential chronic (14-d average) and acute (single-day) estimated daily intakes (EDI) were computed for olestra, a fat replacement intended for use in preparing savory snacks. The EDI were computed from eating occasions reported during a 14-d Menu Census survey among 4741 consumers; values were increased by 10% for conservatism. The eating occasions included all meals and in-between meal occasions eaten at home or away. Data from only those individuals who ate savory snacks at least once during the 14 d were used; this included 3820 individuals (81% of the sample) and represented a total of 16,067 eating days (24% frequency). The estimated mean chronic intake ranged from 1.8 to 4.7 g/d, depending on age and gender; at the 90th percentile, the range was 4.1-11.0 g/d. For all ages and both genders, the estimated mean intake was 3.1 g/d. Estimated acute intakes at the mean and 90th percentile ranged from 5.5 to 16.5 g/d and from 10.2 to 24.0 g/d, respectively, depending on age and gender. For all ages and both genders, the estimated mean intake was 10.2 g/d. The lack of parity in the chronic and acute intake estimates indicates that savory snacks are not eaten on a daily basis by the majority of snack eaters. The survey data were analyzed to understand the potential temporal eating patterns of olestra from savory snacks. When snacks were consumed, on average, 69% of the eating occasions were with main meals and 31% were between meals. Savory snacks did not contribute a major fraction of total food to the diet; only 7 and 18% of main meals contained a savory snack food at the 50th and 90th percentile, respectively. For the 50th-percentile consumer (all ages, both genders), savory snacks were eaten four times during the 14-d survey period, and the eating occasions occurred on 3 d. Comparable results for 90th-percentile consumers were 10 eating occasions and 8 eating days.

The purpose of this study was to identify the effectiveness of a nutrition education program of reducing children's sugar intake based on social cognitive theory. This education program composed of 6 units was conducted in discretional activity class of the 3 rd and 4 th grade elementary school students. The results are as follows: First, the rate of correct answers and score of nutrition knowledge significantly increased after nutrition education. The scores of nutrition education in male students, students whose mothers have no job, and students with skinny physiques were much improved after nutrition education(p<0.05, p<0.01, p<0.001, respectively). Second, the dietary attitudes toward reducing sugar intake and checking nutrition labels significantly improved(p<0.05). And also, it tended to decrease in preference and intake of sweet foods. Third, the consumption of candy․caramel․jelly(p<0.05), yogurt(p<0.05), jam․honey(p<0.05), and ice cream(p<0.001) were reduced after nutrition education. Besides, obese students' consumption of isotonic beverages, carbonated beverages, and fruit juice was reduced. Therefore, a positive change in dietary behavior appeared. Based on the above results, we confirmed that the nutrition education program focusing on reducing sugar intake applied with social cognitive theory was effective for improving the nutrition knowledge, dietary attitude and dietary behavior in sugar intake in elementary school students. Especially, this program showed the improvement in nutrition knowledge as well as dietary attitude and behavior in sugar intake among obese children. Since nutrition education during childhood significantly influences lifetime-health and disease prevention, it is necessary to develop theory-based nutrition education program and practice systematic and constant nutrition education in elementary schools.

In this study, the soy food intake behaviors including perception and intake frequency of soybean foods by sociodemographic variables were analyzed in housewives. The perception of housewives for soy foods showed that soybean paste, soybean curd, and Dambuk were high in the descending order for nutritional quality and health promotion effect, and soybean paste received the highest score in taste and flavor. Soybean sprouts received the highest evaluation score in the economic aspect. In the aspect of safe food, soybean paste received the highest evaluation score, as mush as a traditional food. The analysis of perception by sociodemographic variables showed that soybean curd, Dambuk, and soybean sprouts had higher perceptions as education level increased, and soy milk had higher perceptions in subjects with younger age and with employment. In the intake frequency, more than 50% of the subjects had soybean curd, soybean sprouts, and soybean paste more than once a week. The analysis for correlation between the intake frequency of soy foods and the degree of perception showed that taste and flavor had high correlation with the intake frequency of soy foods except soybean sprouts. The intake frequency of soybean paste, Dambuk, and soy milk had positive correlations to familiarity and that of soy milk had positive correlations to nutrition and health perception, and those of soybeam paste, soybean sprouts, and soy milk had positive correlations to safe food perception. From the above results, housewives in Korea had very high perceptions to nutritional quality and health promotion effect of soy foods and the degree of perception and accompanied intake frequency had significant differences by age, education level, and economic level among sociodemographic variables.
