Beans have long been known as a delicious, excellent source of protein and fiber, and have lately come to the fore as good sources for thiamin, iron, folate and potassium. Recent studies have found that they're also a great source of antioxidants! And they're great for weight-conscious!
So when looking for protein-rich foods, watch what comes along with the protein. Vegetable sources such as beans, nuts, and whole grains are excellent choices and include healthy fiber, vitamins and minerals! The healthiest animal protein sources are fish and poultry. If you're an eater of red meat, choose the leanest cuts and moderate portion sizes.
