How many studies support Legumes?

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 backed by 3 published studies in Vitaebase's database, including 2 meta-analyses, the most recent from 2023 -- a modest but real research base.
