The Japanese diet from 1975 delays senescence and prolongs life span in SAMP8 mice

Identification of Characteristic Components and Foodstuffs in Healthy Japanese Diet and the Health Effects of a Diet with Increased Use Frequency of these Foodstuffs

“…In contrast to the effect on cholesterol, the test diet had no effect on white adipose tissue weight. Our previous study suggested that diversity of foodstuffs has a major influence on visceral fat accumulation, whereas in the current study, the type of each foodstuff was almost the same in the 1975 and test diets. This may explain the absence of a difference in white adipose tissue weight between the two diets.…”

“…The contents of the Japanese diet have been greatly altered by Western influence in the last 50 years . In comparisons of representative freeze‐dried and powdered Japanese diets from 1960, 1975, 1990 and 2005 (based on National Health and Nutrition Research (NHNR) data) fed to mice, we found that the 1975 diet gave the strongest suppression of visceral fat accumulation and the greatest overall health benefits. We also investigated whether this effect of the 1975 diet depends on the macronutrient ratio; i.e., the ratio of proteins, lipids, and carbohydrates.…”

Fermented Soybean Suppresses Visceral Fat Accumulation in Mice

“…As the Japanese diet has become more westernized in the past 50 years, the prevalence of lifestyle diseases has increased . Therefore, we also examined the contents of Japanese diets from different years to determine which was most effective for maintaining good health . The Japanese diet from 2005 was defined as the modern Japanese diet.…”

Comparison of the Effects of the 1975 Japanese Diet and the Modern Mediterranean Diet on Lipid Metabolism in Mice

“…Therefore, the 1975 Japanese diet appears to limit accumulation of visceral fat and is the least likely to cause obesity among Japanese diets from different eras. In subsequent studies, the 1975 Japanese diet has been shown to have beneficial effects on diabetes, fatty liver, dementia and lifespan 8,10 .…”
