Vitamin B6, Amino Acid Tied To Reduced Lung Cancer Risk

Smokers with higher levels of vitamin B6 and a certain essential amino acid have less risk of developing lung cancer than those lacking the nutrients, cancer experts said Tuesday. A study of nearly 400,000 participants that included current and former smokers in 10 European countries found that people with high levels of vitamin B6 and the essential amino acid methionine -- found in most protein -- were at least half as likely of getting lung cancer.
