Researchers found that each daily glass of red wine afforded 13% protection against lung cancer while rosé appeared to have no protective effect and white wine appeared to increase the risk.

Red wine is thought to owe its health benefits to tannins—plant chemicals that bind protein in plants—and resveratrol—a substance found in the skin of red grapes that’s thought to activate cell defenses that promote longevity by mimicking the body’s starvation mode.

Last year, a similar study on lung disease by the National Heart and Lung Institute at London’s Imperial College examined the role of these compounds in stopping chronic obstructive pulmonary disease (COPD), another lung disease caused by smoking.

One of the hallmarks of this illness is a slow deterioration of the lungs caused by the inflammation of immune cells, but researchers found that the antioxidant properties of tannins and resveratrol neutralized cell-damaging oxidants and slowed inflammation.
