Taking Charge: 饮食、生活方式和癌症
Scientists are still learning about the relationship between diet and lifestyle factors and the development of many types of cancers. For some cancers, such as colon cancer, there appear to be clear links to diet and activity.
At this time, less is known about the effects of diet and lifestyle factors on ovarian cancer. 在乳腺癌中, it appears that consumption of just a few alcoholic beverages per week may increase the risk of developing the disease. There is some evidence that diets high in fruits and vegetables decrease the risk for breast cancer, but the link is weaker than it is for other types of cancers.
为什么饮食很重要
Certain fruits and vegetables contain substances that appear to protect the body against the development of cancers. Some of these substances are called antioxidants, because they fight the oxygen-induced damage to body tissues that occurs as a result of normal body processes. Antioxidants include vitamins C and E, 硒, carotenoids and some other plant substances called phytochemicals.
Although researchers have shown that antioxidants in foods can help lower your risk of some cancers, artificial supplements do not seem to have this benefit.
