Whole food sources refer to unprocessed or minimally processed foods that are as close to their natural state as possible. These types of foods provide more nutrients, vitamins and minerals than highly refined or processed foods because they retain most of their original components such as fiber, antioxidants, and other beneficial compounds. Whole food sources are typically plant-based but can also include lean meats, poultry, fish, eggs, dairy products, nuts, seeds, and healthy oils. Consuming whole foods is important for maintaining good health because they provide essential nutrients that our bodies need to function properly while reducing the risk of chronic diseases such as heart disease, diabetes, and cancer.
