Vegans get protein by incorporating healthy foods like nuts, seeds, beans, oatmeal, and green vegetables into their diet. Consuming protein on a vegetarian diet is essential because it provides energy, builds healthy muscle mass, and supports your body function properly. Other good sources of protein for vegans include seitan, tofu, lentils, chickpeas, edamame, teff, green peas, and of course, our delicious vegan protein bars.
