Swap some refined rice and flour for whole grains
People who eat an extra 90 g of whole grains daily have a roughly 17% lower risk of dying over the same period. That amount equals about three servings. The risk continues to drop when intake rises to around 200 g per day.

Whole grain options like brown rice, oats, and whole wheat flour cost slightly more than refined varieties and require no extra prep time. The main challenge is adjusting to their different taste and texture.
Pooled data from multiple observational studies (no participant grouping used) shows that adding 90 g of whole grains daily cuts mortality risk by roughly 17% (RR 0.83). This effect holds true up to 210–225 g per day. Another pooled analysis found an 8% lower risk per extra daily serving (RR 0.92).

Open source linkYou do not need to replace all refined grains with whole grains — swapping just half delivers the bulk of these benefits. Keep in mind these studies are observational, so participants eating more whole grains tend to be healthier overall, which may inflate the reported effect sizes. Results across individual studies also vary widely (I² 83%, a high value indicating substantial inconsistency between study conclusions).
