Higher Vitamin E Levels are Associated With Lung Health

In an ongoing study of 1,088 incident lung cancer cases and 1,414 healthy controls, researchers studied the associations between four tocopherols (alpha-, beta-, gamma-, and delta-tocopherol) in the diet and lung cancer risk. Higher intakes of alpha, beta and gamma-tocopherols were found to be associated with a reduced risk of lung cancer. When groups with the highest and lowest alpha-tocopherol levels were compared, those with intakes in the highest 25 percent showed a 61 percent reduction in lung cancer risk. For both beta-tocopherol and gamma-tocopherol, subjects whose intake was highest experienced a 44 percent lower risk compared to the lowest intake groups. No significant association was observed between delta-tocopherol and lung cancer risk.
