Nutritional supplements abound. Still, if you want to improve and protect your health, think real food. If you depend on supplements rather than eating a variety of foods, you miss the potential benefits of antioxidants, fiber and other nutrients that only whole, unprocessed foods can provide. For example, you can get vitamin C from a pill or from an orange. But the orange is the better choice because it also provides some fiber, beta carotene, calcium and other nutrients.
