Higher adherence to plant-based dietary patterns is associated with significantly lower risks of type 2 diabetes, cardiovascular disease, cancer, and all-cause mortality.
Adopting a diet rich in vegetables, fruits, whole grains, and legumes while reducing animal products is associated with a lower risk of type 2 diabetes, heart disease, cancer, and early death. Focus on 'healthy' plant foods rather than refined carbohydrates for the best results.
A greater adherence to plant-based dietary patterns was consistently associated with lower risks of T2D, CVD, cancer, and mortality. The random-effects pooled RR was 0.82 (95% CI: 0.77–0.86), 0.90 (95% CI: 0.85–0.94), 0.88 (95% CI: 0.84–0.92), and 0.84 (95% CI: 0.78–0.92), respectively.
Why this rating
Large-scale meta-analysis of prospective observational studies (n=2.2M), though heterogeneity is noted.
