Taking about three times as much vitamin D as the norm may lower an individual's risk of developing colon, breast or ovarian cancer, a study says.
Americans typically take 320 units a day of the vitamin£¬consisting of 200 from food and 120 from supplements. Daily intake of about 1 £¬ 000 units may cut the odds of getting colon cancer by about half,and the chances of getting breast or ovarian cancer by about a third, ac?cording to the researchers.
Vitamin D supplementation could reduce cancer incidence " at low cost£¬with few or no side effects¡±£¬the researchers said in an article appearing in the February 2006 issue of the American Journal of Public Health.
"The strongest effect is for colorectal cancer,¡±said lead author Cedric Garland, 59, a pro?fessor of family and preventive medicine at University of California-San Diego, in a telephone interview Tuesday. Garland said.
The U. S. National Academy of Sciences recommends daily vitamin D intake of at least 200 units for adults 50 or younger; 400 units at ages 51 to 70 £¬and 600 units for people 71 or older. The upper limit for safe intake is 2£¬ 000 units daily. Thus,the dose recommended by the re?searchers is beyond what most people now get and what the government recommends.
A glass of milk contains about 100 units of the vitamin, Garland said. While cod liver oil is rich in vitamin D£¬it also contains a lot of vitamin A and the two vitamins compete for reception by the body,Garland said. He doesn't recommend cod liver oil as a source of vitamin D.
To ensure getting 1 £¬ 000 units of vitamin D, most people probably can take two 400-unit tablets£¬with the other 200 units coming from foods such as salmon£¬orange juice£¬yogurt and cheese, Garland said. Getting enough vitamin D through supplements would cost less than 5 cents a day£¬he said.
Although sunlight helps the body produce natural vitamin D£¬the researchers urged getting the minimum of 1£¬ 000 units through food and supplements. Dark-skinned people, who need more sunlight to make vitamin D.are at increased risk of vitamin D deficiency£¬the scientists said.
