Lung cancer is known to be the most common cancer around the world. Tobacco avoidance is one of the best ways to prevent lung cancer but researchers investigated other ways to prevent lung cancer, including dietary factors. The study, performed in 2010 showed how improving intake of vitamin B could lessen the risk of developing this disease by 50 percent or more.
The study, published in the Journal of the American Association revealed individuals with high blood levels of vitamin B6 may be less likely to develop lung cancer compared with their contemporaries with lower vitamin B6 levels.
Between 1992 and 2000, the European Prospective Investigation into Cancer and Nutrition (EPIC) obtained blood samples from 380,000 participants from 10 countries; 899 of these subjects developed lung cancer during a 12-year follow-up period. These participants were matched to a control group of 1,770 by age, gender, country, and date of blood collection. Blood samples were analyzed for vitamin B levels and related biochemicals, such as methionine, an essential amino acid our body do not produce on its own. Methionine must be consumed in our diet.
It was found vitamin B6 and methionine both appear to lessen lung cancer risk in both smokers and nonsmokers alike. However, researchers highlighted even though vitamin B6 reduce the risk of lung cancer for smokers, it is to be kept in the mind that tobacco use should be reduced since smoking is the leading cause of lung cancer.
It was also noted that long term consumption of adequate B vitamins appears to provide the most benefit and protection against cancer. There is no evidence that short-term doses of B vitamins would be protective.
Sources of vitamin B6 are beans, grains, meat, poultry, fish, starchy vegetables and fruits( other than citrus). Chickpeas are also a great source of B6. Methionine is found in sesame seeds, soy products, peanuts and lentils. Smaller amounts are found in many fruits and vegetables, such as broccoli, spinach, sweet corn cauliflower and asparagus.
The amino acid methionine is available as a supplement. In food, it is primarily found in animal products like fish and red meats, as well as dairy and eggs.
