Switching to nuts is also associated with lower risk of type 2 diabetes and all-cause mortality

In a recent systematic review and meta-analysis published in BMC Medicine, researchers summarized and evaluated the evidence for associations between replacing animal-based foods with plant-based foods and cardiometabolic health and all-cause mortality.

The study included 37 prospective cohort studies based on data from 24 cohorts in the United States, Europe and Asia. The results showed that replacing 50 grams/day of processed meat with 28-50 grams/day of nuts was associated with a 27% reduction in the risk of cardiovascular disease. Replacing 50 grams/day of red or processed meat with 10-28 grams/day of nuts was associated with an 8% and 22% lower risk, respectively, of type 2 diabetes incidence. Moreover, replacing 50 grams/day of red meat with 10-50 grams/day of nuts was associated with a 7% lower risk of all-cause mortality, while replacing 50 grams/day of processed meat with 28-50 grams/day of nuts reduced all-cause mortality by 21%.

These findings suggest that a shift in dietary habits away from animal-based foods —especially red and processed meat— and towards nuts would have an important impact on cardiometabolic health.
