Current and former smokers who took multi-vitamins or had good levels of folate had less risk of lung cancer, a new study reveals.
Doctors in a lung cancer study measured the diets of 1,100 current and former smokers who also gave a sputum sample containing respiratory-tract cells. Researchers examined the cells for the irregularities in DNA that can trigger abnormal rapid growth of cancer cells.
Scientists found that those who took multi-vitamins were 43 percent less likely to have gene irregularities than those who did not.
Those who got at least 750 mcg of folate per day were 16 percent less likely to have gene irregularities compared to those who got less folate.
