Vitamin D may halve the risk of cancer

Scientists in the US have confirmed that vitamin D reduces the risk of developing some common cancers by 50%, such as breast, colon, ovary, etc., not just at supporting the body Calcium collection.

California University has reviewed more than 60 studies on the relationship between vitamin D and cancer published between 1966 and 2004, including 30 colon cancer reports, 13 on cancer. breast, 26 pancreatic cancer and 7 ovarian cancer.

The results showed that the role of vitamin D cannot be ignored in some forms of cancer. Specifically, taking 1,000 IU (international units) of vitamin D, equivalent to 25 mg daily, can reduce the risk of developing colon cancer by 30%, breast and ovarian cancer.

The "natural" form of vitamin D is D3, produced under the skin after absorbing the sun. However, it can be added from oily fish (salmon, tuna .), vegetable oil and meat.

Survey results may help explain why the survival rate of African-American Caribbean has lower rates of breast, colon, pancreas and ovarian cancer than Caucasians. "Maybe because black skin doesn't synthesize vitamin D as well as white," Cedric Garland, the team leader, said.

However, caution should be taken when taking vitamin D because more than 2,000 IU (50 mg) each day can cause the body to absorb too much calcium, threatening to damage the liver and kidneys.
