Boosting your vitamin D intake can dramatically reduce your risk of breast and other cancers, a new study found. The research adds to growing evidence that vitamin D can help protect against many forms of cancer as well as other diseases, Creighton University researchers said. But an American Cancer Society spokeswoman urged caution in interpreting the findings, saying it was premature to recommend taking vitamins to reduce cancer risk. Joan Lappe, a Creighton University professor of medicine and nursing and lead author of the study, said, ‘What we can say from our study is that 1,100 international units (IUs) a day of vitamin D definitely decreased the incidence of cancer.’ That amount of the vitamin is nearly triple the recommended intake for the age group studied — women who were 55 and older when the four-year study started. Lappe’s team followed 1,179 study participants who were all postmenopausal and lived in rural Nebraska. The women were free of known cancers for the 10 years before entering the study. They were assigned to one of three groups and followed for four years. One group took 1,400 to 1,500 milligrams of supplementary calcium a day, another […]
