Sunflower seeds have the power to nourish the entire body. They are a rich source of easily digestible and assimilable protein which is essential for the repair of tissues, nerves, and cells. Sunflower seeds are an excellent source of Vitamin D, B-complex, Vitamin K, and Vitamin E. Vitamin E, also known as tocopherol, is an antioxidant that can protect cells from free-radical damage and aid in preventing heart disease, cancer, and eye degeneration such as cataracts.
