What Are Whole Food Sources?
Whole foods include fruits, vegetables, whole grains, nuts, seeds, legumes, and animal products that are free from artificial additives, preservatives, and refined ingredients. Unlike processed foods, whole foods are closer to their natural form and provide a rich array of vitamins, minerals, antioxidants, and fiber.
