Remarks by President Obama in Address to the United Nations General Assembly. United Nations. New York, New York. 10:12 A.M. EDT. PRESIDENT OBAMA: Mr. President, Mr. Secretary General, fellow delegates, ladies and gentlemen: It is a great honor for me to be here today. I would like to talk to you about a subject that is at the heart of the United Nations -- the pursuit of peace in an imperfect world.
Ultraviolet (UV) Exposure Is Not the Answer. Our bodies manufacture vitamin D when the sun's ultraviolet B (UVB) rays interact with 7-dehydrocholesterol (7-DHC) present in the skin. However, we can produce only a limited amount of vitamin D from UVB.
Vitamin D is a fat-soluble vitamin, which means it's stored in fatty tissue. It's often known as the sunshine vitamin, because your body can make vitamin D on its own after exposure to sunlight. You can also take supplements of vitamin D, but very few foods contain this vitamin. Vitamin D helps your body absorb calcium and phosphorous, which are both needed for bone formation. It also assists in muscle, heart, lung, and brain function.
