Folate
Cooked pinto beans are an excellent source of folate (vitamin B9), with 100 g providing a whooping 172 mcg of folate, which is 43% of daily dietary intake. Although folate content in black beans is appreciable, it is notably less as compared to pinto beans. 100 g of cooked black beans provide around 149 mcg of folate, which is 37% of recommended daily intake. Thus, among the two types of beans, pinto beans are a richer source of folate.
