For years, we’ve been warned that exposure to sunlight is prescription for skin cancer. Now, though, some physicians are saying that limited amounts of sunshine can help prevent breast, endometrial and other serious cancers.
Why the change? Sunshine is the best source of vitamin D, the nutrient that researchers believe helps protect against cancer, and possibly heart attack and multiple sclerosis.
For example, a study of 1,200 Nebraska women found those who took regular doses of vitamin D had a 60 percent lower incidence of breast, lung and colon cancers when compared to women who didn’t. Other research, while not completely supporting this finding, does suggest that vitamin D can help prevent colon-rectal cancer.
Here’s the problem, though. Ultraviolet B rays that help produce vitamin D can also cause skin cancer. That’s why many dermatologists advocate wearing sunscreen, which limits the body’s ability to produce Vitamin D.
There is a solution. Take an oral supplement. Dr. Jeanine Downie, a dermatologist from Montclair, N.J. says it’s the safest way to get vitamin D.
“Melanoma is now increasing at an alarming rate,” she says, adding that by 2010, an estimated 1 out of 50 people will have skin cancer. “The safer and effective way of getting Vitamin D is through vitamins, food and milk.”
How much should you take? Right now, the recommended daily dose is between 200 to 800 international units, depending on your age. But some researchers are saying that dose is too low now that we are decreasing our time in the sun. Taking more than 2,000 IU can be dangerous.
