Lung cancer risk 'cut by B vitamin' - BBC

People with plenty of a B-vitamin in their blood appear to be at a reduced risk of lung cancer, even if they smoke, a European study suggests.

High levels of Vitamin B6 and the amino acid methionine cut the risk by half, a study of 400,000 people suggested. These occur naturally in nuts, fish and meat or can be taken as supplements.

But experts told the Journal of the American Medical Association that stopping smoking remained the best way of reducing lung cancer risk. - B vitamin 'cuts lung cancer risk'
