The U.S. Department of Agriculture lists calcium as one of the four nutrients most missing in the American diet. While calcium is important, there are many other minerals and vitamins that are also vitally essential for a healthy structural system. The skin is the largest organ of the body and the most exposed. It is a supple, elastic tissue that conserves heat and moisture. It is the first organ to respond to pain or touch.
Skin also functions as a cooling system and helps regulate internal body temperature.
There are 100,000 strands of hair on the average head. The root is the only living part of the hair. Hair is kept in good condition by the secretions of the sebaceous glands. Internal skin and hair care begins with good nutrition. This includes drinking plenty of pure water, which helps to hydrate the skin from the inside out and also helps flush toxins out of the body.
