According to Traditional Chinese Medicine, the kidneys are the fountain of youth, the foundation for a healthy, vital life and for graceful longevity. Caring for your kidneys is important because they regulate fluid metabolism; supports keen hearing, healthy hair, and strong sexual function; and supplies us with willpower and motivation. Healthy kidneys filter out toxic waste products from your blood caused by environmental toxins and promote biochemical reactions inside your body. Eating the right foods and avoiding excess salt can help support good kidney energy. Foods helpful for your kidneys are those rich in antioxidants, healthy proteins and low in phosphorous.The kidneys also secrete hormones which stimulate red blood cell production in the bone marrow and Calcitriol, an active form of vitamin D, which is now recognized as essential to a myriad of body functions such as immune and cognitive function, healthy fertility, weight regulation, and of course, bone health.
