What is a good low-carb, vegetarian diet?
Vegetarian sources of protein include eggs and milk products, depending upon the exact type of vegetarianism followed. For vegans, soy milk, walnuts, sunflower seeds, almonds and pumpkin seeds fulfill protein requirements. Tofu is another good source of protein, as it contains approximately 10 grams of protein per 3-ounce serving, while seitan, which is derived from wheat, contains 20 grams of protein for every 3 ounces.
