非洲马赛部落：为何长期低脂饮食 + 大量步行，能预防代谢疾病？

Maasai tribe, Africa: Why can long-term low-fat diet + lots of walking prevent metabolic diseases?

马赛人以牛肉、牛奶和血为主要食物（几乎无精制糖和加工食品，碳水化合物摄入仅占 20%）。

The Maasai mainly eat beef, milk, and blood (almost no refined sugar or processed food; carbohydrates account for only 20% of intake).

每日步行 15-20 公里（放牧、迁徙），相当于中等强度运动 3-4 小时（肌肉持续消耗葡萄糖，提高胰岛素敏感性）。

They walk 15-20 km daily (herding, migrating), equivalent to 3-4 hours of moderate exercise (muscles continuously consume glucose, improving insulin sensitivity).

饮食中的共轭亚油酸（来自牛肉）可调节脂肪代谢（减少腹部脂肪堆积），与运动协同维持体重稳定。

Conjugated linoleic acid in their diet (from beef) regulates fat metabolism (reducing abdominal fat accumulation), working with exercise to maintain stable weight.

尽管摄入大量动物脂肪，但因能量消耗与摄入平衡，马赛人糖尿病发病率仅为发达国家的 1/10。

Despite high animal fat intake, due to balanced energy consumption and intake, the Maasai have 1/10 the diabetes rate of developed countries.
