Vitamin D could help delay aging and reduce cancer risk

Researchers in the US have discovered a way of involving vitamin D to protect healthy prostate cells from damage that can result in cancer.

A study conducted by a team of researchers at the University of Rochester Medical Center found that vitamin D induces a gene known as G6PD to increase the production of the enzyme glucose-6-phosphate dehydrogenase, which protects cells from oxidative stress.

Experts say that exposure to some chemicals or forms of radiation can produce high levels of free radicals that can damage DNA and play a significant role in speeding aging or causing cancer.

Lead researcher Yi-Fen Lee, associate professor of urology at the Medical Center, said: "Many epidemiological studies have suggested the beneficial properties of vitamin D.

"Our findings reflect what we see in those studies and demonstrate that vitamin D not only can be used as a therapy for prostate cancer, it can prevent prostate cancer from happening."

Reducing DNA damage in turn lowers the risk of developing cancer and slows down the aging process.

Professor Lee added: "Taking a supplement is especially important for senior citizens and others who might have less circulation of vitamin D, and for people who live and work areas where there is less sunshine."
