The "Green" Protein Diet

Vegetable sources of protein, such as beans, nuts, and whole grains, are excellent choices for your protein diet, and they offer healthy fiber, vitamins and minerals.

Eat soy in moderation. Tofu and other soy foods are an excellent red meat alternative. But don't go overboard; 2 to 4 servings a week is a good target. And stay away from supplements that contain concentrated soy protein or extracts, such as isoflavones, as we just don't know the long term effects.
