Based on the results of a previous WHO-CARDIAC study, this study was designed to test the effect of the daily consumption of a diet rich in potassium with optimal salt content, rich in fish meat and soy isoflavones, corresponding to the ingredients of a traditional Japanese diet. The test meals were a Balanced Lunch (BL) with chicken as the main dish and a Fortified Lunch (FL) with fish and soy as the main dish, which appeared the same. A double-blind, randomized controlled trial was conducted in 64 relatively obese men (47.2 ± 5.5 years old) who consumed the lunch at their work site for 4 weeks. All participants underwent fasting blood sampling, 24-h urine collection, as well as measurements of height, weight, and blood pressure before and after the intervention. Body mass index, blood pressure, and HbA1c were significantly improved and a 3-g reduction of salt intake was proven by 24-h urine collection in both groups. Moreover, HDL cholesterol and the Atherogenic Index (AI) were significantly improved in the FL group. In conclusion, the risks of lifestyle-related diseases in working men were reduced by one meal per day intervention of optimally-salted traditional Japanese diets containing soy and fish nutrients with high vegetable ingredients.
基于世界卫生组织心脏病学研究的结果，本研究旨在测试富含钾、适量盐、富含鱼肉和大豆异黄酮的饮食，即传统日本饮食的成分，对日常消费的影响。测试餐是均衡午餐（BL），以鸡肉为主菜，强化午餐（FL），以鱼和大豆为主菜，外观相同。在 64 名相对肥胖的男性（47.2±5.5 岁）中进行了一项双盲、随机对照试验，这些男性在工作地点食用午餐，持续 4 周。所有参与者在干预前后均进行空腹采血、24 小时尿液收集以及身高、体重和血压测量。两组的体重指数、血压和 HbA1c 均显著改善，24 小时尿液收集显示盐摄入量减少 3 克。此外，FL 组的高密度脂蛋白胆固醇和致动脉粥样硬化指数（AI）显著改善。总之，每天摄入一顿含有高蔬菜成分的大豆和鱼肉营养的传统日本饮食，可以降低工作男性患与生活方式相关疾病的风险。
