Vitamin B6 May Slash Lung Cancer Risk
A new analysis found that vitamin B6 may significantly reduce the risk of developing lung cancer.
The analysis was conducted by the International Agency for Research on Cancer in France and published in the June 2010 issue of the Journal of the American Medical Association.
The researchers used the data of nearly 400,000 people who donated blood for the European Prospective Investigation into Cancer and Nutrition study.
The researchers took 899 participants with lung cancer and compared them to 1,770 cancer free participants.
The researchers found that higher blood levels of vitamin B6 were associated with a 50% overall reduction in lung cancer risk. The link between B6 and lung cancer risk was apparent among smokers and non-smokers alike.
The researchers also found that the amino acid methionine, which is found in most protein and B12 may also be beneficial. High levels of B12 combined with methionine and B6 were associated with a 66% reduction in lung cancer risk.
Previous research has shown that B vitamins may have a number of other potential health benefits beyond cancer prevention. These benefits include reducing the risk of Alzheimer’s and Parkinson’s disease as well as promoting cell growth and supporting metabolism.
Our bodies do not naturally synthesize vitamin B6 so the only way to get it is from a supplement or through dietary sources. Some foods rich in B vitamins include broccoli, asparagus, potatoes, tuna and salmon. Many milk and flour products are also fortified with B vitamins.
