日本 VS 米国、どちらの食事が健康的？ー1975年の日本の食事が一番健康的

Japan vs. USA, which diet is healthier? – 1975 Japanese food is the healthiest 

東北大学、都築先生が食事に関する研究を発表。驚くことに、炭水化物、脂質、タンパク質の量（バランス）は日本食と米国食で顕著な差はなかったが、日本食群はエネルギー・糖質・脂質代謝系の遺伝子発現が全体的に高く、ストレス応答遺伝子の発現が低かった。さらに、内臓脂肪量が少なく、血中脂質濃度は低かった。さらに現在の日本の食生活では長寿化にブレーキがかかることを懸念。1975年の日本の食事が健康長寿に貢献していることを示唆した（1975年の具体的なメニュー付）。

Tohoku University and Prof. Tsuzuki presented research on diet. Surprisingly, the amount (balance) of carbohydrates, lipids, and proteins was not significantly different between Japanese and US diet, however, the Japanese food group generally had high gene expression of energy, carbohydrate, and lipid metabolism systems, and the stress response of gene expression was low. Furthermore, the amount of visceral fat was small and the blood lipid concentration was low. Studies indicated some concerns that there will be a brake on longevity among Japanese with their current diet. This suggests that Japanese diet in 1975 contributed to healthy longevity (specific menu from 1975 in Japan is available in this article).
