High levels of amino acid methionine also seem to help, study finds
While it may be a bit early to start popping supplements, a new study finds that people with high levels of vitamin B6 may be less likely to develop lung cancer than those with low concentrations. Reporting in the June 16 Journal of the American Medical Association, researchers also note a seemingly protective effect from high levels of the essential amino acid methionine and a weaker healthful effect from high levels of folate, another B vitamin.
It’s not yet established how high amounts of these compounds might protect the body from lung cancer, but all three are involved in the maintenance of DNA. In the vast majority of lung cancer cases, toxic smoke causes the DNA damage and aberrant cell growth that marks the disease.
Researchers tapped into a massive database of medical information and blood test results obtained from more than 380,000 Europeans in the 1990s. Using medical registries, the researchers identified 899 people in the study who had
