Smokers need more fruits, veggies, tea

What smokers really need is to quit smoking. Well, if better health is a goal, anyway. Short of kicking the habit, though, there is something smokers can do to protect themselves against lung cancer: Eat three servings of fruits and vegetables per day and drink green or black tea.

That's what UCLA cancer researchers say now that they've completed their first-of-its-kind study. They found that high levels of natural chemicals called flavonoids in smokers' diets translated into a lower risk of lung cancer. This is a promising finding since 90 percent of lung cancers are caused by tobacco smoking.

Smokers most protected from the disease are those who ate catechin, found in strawberries and green and black teas, kaempferol, found in Brussels sprouts and apples, and quercetin, found in beans, onions, and apples.

Since this study is the first of its type, researchers hesitate to make any official diet recommendations. And yet, at the same time, they encourage everyone to eat more fruits and vegetables and drink more tea -- because these practices are good for all people, smokers and non-smokers alike.
