Black Beans Packed with both #folate and soluble fiber, black beans should be a staple in your diet. But because black beans also contain more than 15 grams of #protein per one-cup serving, they are especially filling and may even help balance blood sugar. These legumes are also a good source of magnesium – one cup contains more than 30% of #women’s daily requirements – which can improve circulation. #LinaRammal
