Almonds are prevalent tree nuts. Almonds are high in healthy monounsaturated fats, fiber, protein, and various important nutrients. Almonds are high in antioxidants that can protect your cells from oxidative damage, a major contributor to aging and disease. Almonds contain vitamins, minerals, protein, and fiber, so they may offer a number of health benefits. Just a handful of almonds — approximately 1 ounce — contains one-eighth of a person’s daily protein needs.
