Man-Sundown-SweaterETH Health and WellnessVitamin D may reduce prostate cancer risk by acting on a gene that lowers inflammation, according to a study conducted by researchers from the University of Colorado Cancer Center and published in the journal Prostate. Back in 1990, scientists first suggested that vitamin D might be the common variable linking a number of known prostate cancer risk factors, including older age (associated with reduced vitamin D synthesis), living at a northern latitude (where people are more likely to be vitamin D-deficient due to lower levels of the sunlight that stimulates synthesis of the vitamin) and African descent (because darker skin leads to reduced vitamin D synthesis). In addition, studies had shown that prostate cancers diagnosed in the summer or autumn, when vitamin D levels in the body tend to be highest, were less deadly than those diagnosed in the winter or spring.
