Abstract

We examined the protective efficacy of Dietary Education Lunch menus: DEL against metabolic syndrome (Mets) which are served at worksite cafeterias. We have conducted a questionnaire survey on 692 subjects from 5 sites at 3 companies who had DEL for lunch and compared them by their answers for the eating frequency and term. Also implemented a comparative program on 16 entries (men) replacing their lunch with DEL for 3 months (5 work days a week), along with physical examinations, blood tests and questionnaires on dietary habits before and after the intervention. The results of the multiple site questionnaire survey indicated that significant changes in conscious weight loss (p<0.01) and improvement of eating consciousness (p<0.01) were seen in groups with eating frequency of more than 4 times a week. As for the intervention study, the entries showed decrease in abdominal circumference, weight and body fat in 3 month and the blood test results improved significantly in HOMA-R (p<0.001), and γ-GTP, AST, ALT, LDL cholesterol (p<0.05). Concurrently, significant change in dietary habits as “how to eat” and “meal contents” (p<0.01), were seen. The meaningful physical change and laboratory value improvement showed by the continuous eating of DEL are attributed not only to the decreased calorie intake but to the subjects’ alteration of their eating behaviors. It is conceivable that DEL supported the reform of dietary habits only by once a day approach at lunch. The results above leads to the suggestion that DEL can be an effective tool for the prevention of MetS.
