Tobacco smokers who eat three servings of fruits and vegetables a day and drink green or black tea may be protecting themselves from lung cancer, according to a recent UCLA study that appears in the journal Cancer.
Smokers who ingested high levels of flavonoids had a lower risk of developing lung cancer. The flavonoids that appeared to be the most protective included catechin, found in strawberries and green and black teas; kaempferol, found in Brussels sprouts and apples; and quercetin, found in beans, onions, and apples.
Zuo-Feng Zhang, MD, PhD, a UCLA Jonsson Cancer Center researcher and public health and epidemiology professor, said in a press release that flavonoids block the growth and spreading of tumors and stop the growth of cancer cells, which brings on naturally programmed cell death.
