A new study shows that vitamin B6 might play a role in preventing cancer. The study is published in the Journal of the American Medical Association.

It found that adults with higher levels of vitamin B6 in their bloodstreams were half as likely to develop lung cancer as those who had low B6 levels.  The study was based on nearly 400,000 adults from 10 European countries who were current smokers, former smokers or had never smoked.

Doctors advocate that healthy B vitamin levels help to both make and maintain healthy DNA, an important factor in the prevention of cancer. Smoking is responsible for 8 out of 10 cases of lung cancer. Cancer experts, however, says that until these findings are replicated, more research needs to be done.

B6 can be found in a variety of foods. They include: meats, poultry, fish, grains, beans, and certain vegetables and fruits like broccoli and bananas.
