vitamin D is involved in calcium and phosphorus metabolism, promote bone growth. The level of "D 25" (25-OH-D) in human plasma can well reflect the status of vitamin D in the body. This newly published by the nutrition science research of Shanghai Institute of Life Sciences Institute of Chinese (referred to as the Shanghai Institute of life science nutrition) in a China women’s studies conducted jointly with the Tumour Hospital Affiliated to Fudan University, Xuhui District Central Hospital showed that vitamin D supplementation can prevent breast cancer.
investigated by monitoring the vitamin D levels in serum of patients with breast cancer and 593 cases of females in Shanghai area and 580 healthy women showed that vitamin D deficiency is common phenomenon, only 4.8% healthy women and 0.7% breast cancer patients with vitamin D is sufficient. Breast cancer patients with a severe lack of vitamin D are as high as 96.1%, and vitamin D deficiency is significantly associated with the incidence of breast cancer in china.
in the study population, the plasma level of 25-OH-D increased by 1 ng / ml, the risk of breast cancer decreased by 16%. Therefore, vitamin D supplementation to premenopausal women with normal weight may reduce the risk of breast cancer. To this end, we believe that the lack of vitamin D to maintain the status quo, maintaining a suitable level of vitamin D, help prevent breast cancer.
