Vitamin D is not one more reason to consider cholesterol good for the body. The days when vitamin D is seen as a unifunctional vitamin reponsible simply for calcium metabolism and bone health are quickly disappearing into the annals of history.ther sources of vitamin D include fatty fish, some shellfish, egg yolks, and butter -- foods selected almost entirely from the list of those richest in cholesterol. The table below shows the overlap between foods' status as cholesterol-rich and vitamin D-rich.
Vitamin D is the name given to a group of fat-soluble prohormones (substances that usually have little hormonal activity by themselves but that the body can turn into hormones). Vitamin D helps the body use calcium and phosphorus to make strong bones and teeth. Skin exposed to sunshine can make vitamin D, and vitamin D can also be obtained from certain foods. Vitamin D deficiency can cause a weakening of the bones that is called rickets in children and osteomalacia in adults. Two major forms of vitamin D that are important to humans are vitamin D2, or ergocalciferol, and vitamin D3, or cholecalciferol.
