Consuming 28 grams per day costs roughly 200–300 yuan annually. It’s easy to fit into your routine without taking extra time.
People who regularly eat nuts have roughly 20% lower mortality rates than those who don’t. Even eating nuts just once a week yields a 10% reduction in risk. The greatest benefit is seen when intake reaches a daily handful.

22. Eating a small handful of nuts daily
Cost: Consuming 28 grams per day costs roughly 200–300 yuan annually. It’s easy to fit into your routine without taking extra time.
In plain terms: People who regularly eat nuts have roughly 20% lower mortality rates than those who don’t. Even eating nuts just once a week yields a 10% reduction in risk. The greatest benefit is seen when intake reaches a daily handful.
Benefit: Two U.S.-based longitudinal studies tracked 119,000 participants over more than 3 million person-years. Compared to non-nut eaters: individuals consuming nuts less than once a week saw a 7% lower mortality risk (hazard ratio 0.93, 95% CI 0.90–0.96). Those eating nuts once a week had a 11% lower risk (0.89, 0.86–0.93). For intake of 2–4 times weekly, the reduction was 13% (0.87, 0.83–0.90); for 5–6 times weekly, 15% (0.85, 0.79–0.91). Daily consumption resulted in a 20% lower risk (0.80, 0.73–0.86).

Notes: Choose unsalted, unflavored varieties. Nuts are calorie-dense, so avoid eating them in excess as a snack. Keep in mind these studies only track long-term trends — nut eaters generally maintain healthier lifestyles overall, so these figures should be interpreted with some caution.

22. 每天吃一小把坚果
成本: 每天吃 28 克，一年约两三百元。顺手就吃，不占时间。
说人话: 常吃坚果的人，同期死亡的概率比不吃的人低约两成。一周吃一次就能看出差别，低约一成。吃到每天一把，差别最明显。
收益: 两项美国跟踪研究，11.9 万人，300 多万人年。人年就是人数乘以各自跟踪的年数。和不吃坚果的人比：每周吃不到 1 次的人死亡风险低约 7%（风险比 0.93，95% CI 0.90–0.96，这是可信范围）。每周吃 1 次的低约 11%（0.89，0.86–0.93）。每周 2–4 次的低约 13%（0.87，0.83–0.90）。每周 5–6 次的低约 15%（0.85，0.79–0.91）。每周 7 次以上的低约 20%（0.80，0.73–0.86）

备注: 买原味不加盐的。坚果热量不低，别当零食敞开吃。要注意这类研究只是长期跟踪一群人，吃坚果的人整体生活方式更好，所以数字要打个折
