A research group at Nagoya University has revealed the possibility that extreme intake of carbohydrates and fats affects the "long-term life expectancy (life expectancy)" of Japanese people.
A low-carbohydrate diet and a low-lipid diet promote weight loss and improvement of blood sugar levels in the short term, and are thought to be useful in preventing lifestyle-related diseases.On the other hand, in other countries, recent epidemiological studies suggest that extreme carbohydrate and fat intake habits increase the risk of death.Therefore, in this study, we investigated the effects of low-carbohydrate and low-fat diets on long-term prognosis in Japanese.
Using 8.1-year follow-up data of about 9 people from a Japanese multicenter cohort study, we evaluated the relationship between carbohydrate and lipid intake and mortality risk in Japanese people.As a result, when the group with a carbohydrate energy intake ratio of 50-<55% of the total energy intake was taken as the reference group, the overall mortality risk in the low carbohydrate intake group (<40% group) was lower than that of the reference group. increased by 1.59 times and cancer mortality risk by 1.48 times.Among women, the risk of all-cause mortality in the high-carbohydrate group (≥5% group) was 65 times higher than that in the reference group, with a similar trend for cancer mortality after a follow-up period of at least 1.71 years.Regarding lipids, when the group with a lipid energy intake ratio of 20-<25% of the total energy intake was taken as the reference group, the cancer mortality risk of the high-fat intake group (≥35% group) was taken as the reference group in men. The risk of death from cardiovascular disease also tended to increase with lipid intake, 1.79 times that of the group.On the other hand, increased fat intake in women tended to lower all-cause mortality risk and cancer mortality risk.The results of this study indicate that extreme carbohydrate and lipid intake in the Japanese population can affect long-term prognosis, suggesting that low-carbohydrate and low-fat diets may not always be good. pointed out.It can be said that a balanced diet is important when considering future mortality risk.Paper information:[The Journal of Nutrition] Dietary Carbohydrate and Fat Intakes and Risk of Mortality in the Japanese Population: the Japan Multi-Institutional Collaborative Cohort Study
