A recent study published in the British Journal of Nutrition looked at how different foods affect the risk of chronic kidney disease, a condition that gradually reduces kidney function.
In this meta-analysis of prospective cohort studies, researchers combined data from multiple observational studies that followed people over time to see how diet relates to disease risk.
The results showed that nuts may help protect kidney health. Eating about 28 grams (roughly a handful) of nuts per day was linked to a 21% lower risk of developing chronic kidney disease. Other foods associated with reduced risk included legumes, grains, and fish, while high red meat intake increased the risk.
These findings suggest that including nuts in the daily diet could be a simple way to support long-term kidney health.
