High Levels of Vitamin D may Lower Risk of Cancer
Research reveals that high levels of vitamin D might lower the risk of cancer, according to a study conducted on March 7, 2018.
Vitamin D, apart from having benefits on bone diseases, are found to be useful in lowering the risk of chronic diseases such as cancer. There are only limited number of studies conducted based on Asian population. Japan based researchers carried out studies to understand how vitamin D helps in lowering the risk of total and site specific cancer. Data from the Japan Public Health Center-based Prospective (JPHC) Study, which involved 33,736 male and female participants, was analyzed by the researchers.
A detailed information about diet, medical history and lifestyle were provided by the participants. To measure level of vitamin D, blood samples of the participants were also collected. On the basis of level of vitamin D, samples were split into four different groups. Then, for 16 years, participants were monitored. After analyzing many cancer risk factors, a high level of vitamin D was found to lower the risk of cancer. There was no link found for lung or prostate cancer. There are few limitations to this study, as few factors that may have effects on the results are unmeasured.
However, large sample size for overall cancer, long follow-up period and many blood samples that were analyzed are the strengths of this study. According to the researchers, beyond a certain level of vitamin D, there are no extra benefits to it. Researchers said, “Further studies are needed to clarify the optimal concentrations [of vitamin D] for cancer prevention.”
This study is expected to increase the growth of targeted cancer therapies market, as elaborated in the targeted cancer therapies market report published by Coherent Market Insights.
