A group of scientists from the International Agency for Research on Cancer recently tested whether B vitamins,affected cancer risk. Paul Brennan and friends analyzed data on men and women from 13 countries in this study, looking for incidences of lung cancer and testing blood for serum levels of carbon metabolism. The group located a lower risk for lung cancer among patients with high levels of vitamin B6 . As well, less of a risk was also seen for increasing methionine levels. writing that consistent decreases in risk were observed in current smokers, indicating that test results were not due to scientific factors, the researchers conclude that: “Serum levels of vitamin B6 and methionine were inversely associated with risk of lung cancer.”
