Almonds are one of the most nutritious nuts, and are a rich source of protein, fiber, vitamin E, omega-3 and omega-6 fatty acids, calcium, magnesium and zinc. Today this was one of my snacks, 25 nuts equal one serving, 160 calories, 14g fat, 210mg potassium, 3g fiber, and 6g protein. I had 2 servings, or about 50 almonds.
