Sometimes referred to as “the poor man’s meat,” legumes are an excellent source of soluble fiber, which can help keep blood sugar and energy levels stable. As far as plant foods go, most legumes are relatively high in protein and are a good source of slowly assimilating complex carbohydrates. This is great for providing a more stable and longer lasting supply of energy to working muscles. Add them to chilis, stews, and soups, or have them in your salad at lunch to stay full and satisfied well past the three-o’clock slump. Try kidney beans, chickpeas, black beans, lentils, and any of the other varieties you see on grocery store shelves.
