The founder of modern medicine, Hippocrates, accentuated the natural healing powers of proper nutrition, rest, fresh air and hygiene. He was convinced that in nature we find a cure to all diseases. Some 2,500 years later, study after study by the most respected medical centers have linked a simple deficiency of specific nutritional substances to specific, often-debilitating diseases. For example researchers at the Columbia University College of Physicians and Surgeons associate osteoporosis with a deficiency of calcium and vitamin D. Modern medical research has echoed the fact that our body often has the natural power to heal itself but needs the correct balance of vital nutrients and a healthy lifestyle to function correctly.
