Swapping some red meat for fish or poultry
把一部分红肉换成鱼和禽肉
There’s no extra cost or time involved. You’re simply substituting one type of meat for another — no additional purchases needed. The real challenge is adjusting your taste preferences.
Eating two extra servings of processed or red meat each week raises the risk of death by roughly 3% compared to normal intake. Switching to the same amount of fish or poultry eliminates this increase. Within this section, this effect is relatively minor; it’s an easy swap worth making without much effort.

23. Swapping some red meat for fish or poultry
Cost: There’s no extra cost or time involved. You’re simply substituting one type of meat for another — no additional purchases needed. The real challenge is adjusting your taste preferences.
In plain terms: Eating two extra servings of processed or red meat each week raises the risk of death by roughly 3% compared to normal intake. Switching to the same amount of fish or poultry eliminates this increase. Within this section, this effect is relatively minor; it’s an easy swap worth making without much effort.
Benefit: This conclusion comes from pooling data across six U.S. studies involving nearly 30,000 participants. Consuming two extra servings of processed meat weekly raised mortality risk by about 3% (hazard ratio 1.03, 95% CI 1.02–1.05). The same increase applied to unprocessed red meat (1.03, 1.01–1.05). However, replacing those servings with poultry resulted in a ratio of 0.99 (0.97–1.02), and fish gave 0.99 (0.97–1.01); neither showed any statistically significant difference.
Evidence grade: A

Notes: The impact of swapping just two servings per week is quite small; don’t expect a major lifespan extension from this change. When spending money on meat, choosing fish or poultry is the wiser option.

23. 把一部分红肉换成鱼和禽肉
成本: 不花钱，也不占时间。这是把肉换一种，不是多买。难在要改点口味偏好。
说人话: 每周多吃两份加工肉或者红肉，同期死亡的概率高约 3%。换成同样份数的鱼或者禽肉，就看不出升高。这条的效应在本节里偏小，属于顺手就换、不必较劲的事。
收益: 把美国 6 项跟踪研究、近 3 万人合起来算。每周多吃两份加工肉，死亡风险高约 3%（风险比 1.03，95% CI 1.02–1.05，可信范围）。每周多吃两份没加工的红肉，也高约 3%（1.03，1.01–1.05）。同样的吃法换成禽肉，是 0.99（0.97–1.02）；换成鱼，是 0.99（0.97–1.01）。这两项都没看出统计上的差别

备注: 每周两份带来的差别很小，别指望靠换肉多活几年。同样花钱吃肉，可以优先挑鱼和禽肉
