I'm with Nelie here - focus on whole foods and you won't have to worry. The secret to beans for me is good spicing - garlic, cilantro, curry, other indian spicing, hot peppers, you name it. Whole grains are a good idea, too. I also like tempeh. I eat all my carbs in veggies or whole grains to the best of my ability. I really like beans and greens together.
