Extract: For 13 weeks, 20 men (aged 23 to 56), 19 premenopausal (aged 21 to 48), and 14 postmenopausal women (aged 49 to 65) consumed a 7-day rotation menu conforming to dietary recommendations of several research and health organizations. The diets were designed to make minimal changes in the standard American diet by the use of well-accepted normal foods. The average daily composition of the diet was 50% carbohydrate (complex 35%, simple 15%), 35% fat (P:S 0.7), and 15% protein; it contained 100 mg cholesterol, 1 gm sodium, and 14.5 gm neutral detergent fiber per 1,000 kcal. The acceptability of the menus was examined through questionnaires administered after the experimental diet period. Subjects rated the menus and individual foods and made recommendations for improvement of the menus. Most subjects (33 of 41 responding) rated the menu better than or almost as good as their usual diet. Few (9) were ever hungry during the 13-week period. During the study, a number of biochemical parameters were measured; the measurements indicated beneficial results. Blood pressure, cholesterol levels, and glucose responses were all improved after consumption of the menu. The results indicate that with minimal changes in the normal U.S. diet, acceptable menus that have beneficial effects on risk factors for heart disease and diabetes can be developed. (author)
