Not all smokers develop lung cancer. One possible reason may be their nutrient consumption. The EPIC study, which stands for European Prospective Investigation into Cancer and Nutrition, includes more than 500,000 participants. Investigators found that people with higher blood levels of vitamin B6 and the amino acid methionine were less likely to be diagnosed with lung cancer. The researchers were quick to point out that changing diet or taking supplements could not adequately counteract the dangers of smoking. Nevertheless, eating a diet high in beans, grains, meat, poultry, fish along with some fruits, vegetables and nuts may be wise, along with quitting or not taking up smoking.
