Breast Cancer: Vitamin D and calcium can reduce the risk of female breast cancer

October 23, breast cancer research professional journal "Breast Cancer Research and Treatment" (Breast Cancer Research and Treatment) of the Chinese Academy of Sciences published online nutrition, Shanghai Institutes for Biological Sciences such as Wang Hui, a researcher on vitamin D and calcium intake intake of female breast cancer risk between Meta-analysis of research results. Studies have shown that high levels of vitamin D and calcium intake can significantly reduce the risk of women with breast cancer, serum 25 - hydroxy vitamin D (25 (OH) D) levels and risk of breast cancer was significantly negatively correlated, while serum The active form of vitamin D in 1α, 25 - dihydroxy vitamin D (1α, 25 (OH) 2D) levels and risk of breast cancer has nothing to do.

The study found that nutritional supplements through diet or a high intake of vitamin D intake of population groups than the low risk of breast cancer significantly reduced 9% (RR = 0.91,95% CI = 0.85-0.97); serum 25 (OH) D at the highest level of women with breast cancer risk than the lowest serum 25 (OH) D levels of the female of nearly 45% (OR = 0.55, 95% CI = 0.38-0.80); while the serum 1α, 25 (OH) The level of 2D and not associated with risk of breast cancer (OR = 0.99,95% CI = 0.68-1.44). Also found that high calcium intake than women with low calcium intake lower the risk of breast cancer 19% (RR = 0.81,95% CI = 0.72-0.90). The study results indicate that vitamin D and calcium in the breast cancer prevention important role, suggesting that women should pay attention to their daily lives through nutrition, diet, sun exposure and other multi-channel multi-supplement of vitamin D and calcium sufficient to reduce the risk of breast cancer.
