New evidence shows that getting enough Vitamin D may be the most important thing you can do for your health．
You know the usual prescription for good health: a balanced diet with lots of fruits and vegetables, regular exercise, no smoking．Now add this: Spend a little more time in the sun．
Huh? That may sound like medical heresy （反面观点）．After all, we've been warned for decades about the dangers of the sun: wrinkles, age spots and the increasing threat of skin cancer．But new and impressive medical evidence suggests that sunlight is beneficial．The vitamin D it prompts our bodies to make may prevent cancer, protect against heart disease and ward off a long list of disorders such as multiple sclerosis, rheumatoid arthritis, diabetes and gum disease．It is even showing promise as a treatment for heart disease and some cancers．
Long recognized as vitally important for bone building （it's needed for calcium absorption）, vitamin D has now achieved superstar status among nutrients．While all doctors may not agree, many experts are confident enough of its wide-ranging powers to urge that we get much more of it, from the sun and from supplements, as even the best diet in the world may not give us enough．
