Is Legumes good for longevity?

The evidence points that way, though it's not yet conclusive. Direct evidence specifically isolating legumes is limited in this dataset; most supporting studies address broader dietary patterns, such as the Mediterranean diet and general heart-healthy eating, in which legumes are one of several recommended components alongside vegetables, whole grains, and healthy fats. That's reflected in an evidence score of 45/100 for its role in longevity, drawn from 3 studies, with an estimated impact on longevity rated moderate (40/100).
