26 of the Best High Protein Foods

19. Peanut Butter

One serving of peanut butter, two tablespoons, provides seven grams of protein. While eating too much processed peanut butter results in an over-abundance of saturated fat, sticking to the natural varieties provides a high percentage of unsaturated fats; as always, moderation is key. Beyond protein, peanut butter delivers fiber, vitamin E, magnesium, potassium, and zinc. Magnesium is an important one: the mineral is used by every cell and is involved in more than 600 reactions in the body. Despite this, many Americans consume barely 50% of the recommended daily amount.
