In the dead of winter, we don't typically think about spending time outdoors, but according to many physicians we should. The sun is our greatest source of a vitamin that is essential for good health-Vitamin D.  This important vitamin strengthens bones and teeth and is linked to the prevention of heart disease, cancer and many other life-threatening diseases. The recommended daily requirement is 400-600 International Units (IU). In summer, people with dark brown eyes and darker skin turn sunlight from just 15 minutes outside without sunscreen into adequate amounts of Vitamin D.  Even during winter, just a 10-minute walk midday can keep the body's Vitamin D at healthy levels. During brief winter walks, we receive the greatest benefits when we wear no sunscreen and expose as much skin to the sun as possible. Vitamin D can also be obtained from foods. Salmon is one of the best sources of the Vitamin. Egg yolks, cheese, mushrooms and some animals organs contain smaller quantities of it.  To attract consumers, food companies add Vitamin D to some of their milk products. The practice of putting the Vitamin into milk began in the 1930s.At that time, many children were suffering from rickets, an illness that is caused by a Vitamin D deficiency. It made the children's bones soft and weak. Adding Vitamin D to milk helped to solve the problem, and it has been available ever since.  For people who still need more Vitamin D, there is another option: take Vitamin D supplements. These products are widely sold in stores. However, anyone considering taking supplements should consult a physician first.
