22/10/1910 Two new studies from the University of Rochester Medical Center suggest links between vitamin D deficiency and cancer of colon and breast, especially African American women.

Scientists at the University of Rochester, to analyze 224 women treated for breast cancer, they found that 66% of them had moderate and severe deficiency of vitamin D. This deficiency was particularly high among women of color and those who were in an advanced stage of disease.

Although the sample was small, African American women had lower levels of vitamin D. "The information we collect tells us it is important to measure vitamin D levels in patients, and if necessary, address this deficiency with the disease, "said a statement Alissa Huston, assistant professor of the U. of Rochester, who led the research. ...

Although scientists believe it is possible that some of the benefits attributed to vitamin D are more related to body mass index and levels of activity, the investigation showed that several tissues and human cells have receptors for vitamin D, making it a potent regulator of cell growth and activity. The researchers found that vitamin D could improve DNA repair, reducing stimulate inflammation and death of malignant cells.

In another investigation led by Kevin Fiscella and published in the journal Cancer, researchers found that vitamin D deficiency in African Americans may explain the recurrent colorectal cancers and the reason why more blacks die of this disease than whites.

Through an epidemiological study in 91 U.S. adults, the scientists found that just because they are African Americans, the chances of dying from colorectal cancer increased twofold.

In another study that made this year, Fiscella also found that vitamin D deficiency could contribute to African-Americans suffer a greater number of deaths from cardiac arrest.

Many people around the world have low levels of vitamin D. Genetic factors common in black people, such as darker skin, reduce the synthesis of vitamin D. Also, some foods can be rich in vitamin D such as milk, yogourth, eggs and fish, but the high lactose intolerance sufferers mostly blacks may contribute to low vitamin D.
