2. 核桃

In a study out of Marshall University School of Medicine in West Virginia, researchers substituted the equivalent of two ounces of walnuts per day into the diet of one group of mice; the other group was fed a calorically equivalent, but walnut-free, diet.

西弗吉尼亚马歇尔大学医学院的一项研究显示每天把相当于2盎司的核桃放到一组老鼠的食物里，另一组老鼠用同样的食物，但是核桃用相当热量的其他食物代替。

After 34 days, the growth rate of tumors in the walnut eaters was half that of the mice who ate no walnuts. Experts think walnuts' anti-inflammatory properties—may give them their tumor-fighting potential. Still, "walnuts can be part of a healthy diet that can reduce your risk for cancer," says lead researcher Elaine Hardman, Ph. D.

34天后，吃核桃的一组老鼠的肿瘤生长速度比不吃核桃那一组的老鼠慢一倍。专家认为核桃含有抗炎作用——能够抑制肿瘤生长。该实验组组长Elaine Hardman博士说：“核桃是能够降低罹患癌症风险的健康食品。”
