水果和蔬菜为什么很重要

Fruits and vegetables may prevent many illnesses. Eating fruits and vegetables may reduce your risk of cardiovascular diseases, stroke, type 2 diabetes, and even some forms of cancer. The Nurses' Health study and Health Professionals Follow-up study examined nearly 110,000 people over the course of 14 years. Part of the study revealed that the more fruits and vegetables people ate daily, the less chance they would develop cardiovascular diseases.
水果和蔬菜可以预防疾病。吃水果和蔬菜可以减少患上心血管疾病，中风，第二型糖尿病，甚至一些癌症的风险。护理健康研究和健康专业随访研究观察了接近11万人超过14年里的进程。部分研究发现，人们每天吃越多水果和蔬菜，他们就越少机会患上心血管疾病。

The relationship between fruits and vegetables and cancer prevention has been more difficult to prove. However, recent studies show that some types of produce are associated with lower rates of some types of cancer. For example, the World Cancer Research Fund and the American Institute for Cancer Research suggest that mouth, stomach, and colorectal cancers are less likely with high intakes of non-starchy foods like leafy greens, broccoli, and cabbage. Though studies have been mixed, lycopene, a carotenoid that gives tomatoes their red color, may help stave off prostate cancer.
水果和蔬菜跟预防癌症之间的关系已经变得更难去证明了。然而，最近的研究表明，一些食物跟患上较少一些癌症有关。例如，世界癌症研究基金会和美国癌症研究院表明，高摄入无淀粉食物，如绿叶蔬菜，花椰菜和大白菜，那么患上口腔，胃部和结肠直肠癌症的几率就会减少。尽管研究已经混合在一起了，但是番茄红素，一种使番茄变红的类胡萝卜素也可以帮助预防前列腺癌。
