- Four Kinds of Anti-cancer Fruits
According to the researches on cancer, the World Health Organization and the United States Department of Agriculture have pointed out that, eating at least five kinds of vegetables and fruits every day can reduce the risk of cancer by 20%. Research shows that there are more than ten kinds of fruits which can effectively reduce the risk of suffering from cancer. These fruits include strawberry, orange, apple, honeydew, kiwi, watermelon, lemon, grapes, pineapple, etc. Some special ingredients contained in these fruits play an indispensable role in preventing colon cancer, breast cancer, prostate cancer, stomach cancer, and so on. In the following passage, we will introduce four kinds of anti-cancer fruits for you.
Among all the anti-cancer fruits, strawberry plays the best effect. Strawberry contains a kind of magic tannic acid substance, which can play an anti-toxic effect in the body, so as to prevent the formation of cancer cells. In addition, strawberry also contains a kind of amine substance, which has good effect in the prevention of leukemia and other diseases related with blood.
Citrus fruits include orange, lemon, grapefruit, etc. This kind of fruits contains a large number of bioflavonoids, which can enhance the activity of certain enzymes in human skin, lung, stomach and liver, and change the fat-soluble carcinogenic substance into water-soluble, so as to make them not easy to be absorbed and can be expelled out of the body. At the same time, they can enhance the absorptive capacity of vitamin C by the human body. Vitamin C is an important cancer substance, which can enhance human immunity, prevent the formation of nitrosamines--a strong carcinogen. What's more, it also has certain effect in the prevention and treatment of gastrointestinal cancer.
Kiwi contains plenty of vitamins, especially vitamin C, the content of which is 4 to 12 times as that of orange. Through the researches in recent years, it is confirmed that kiwi contains a kind of active ingredient, which can block the formation of carcinogenic "nitrosamines" in the human body. As a result, it has a good effect in preventing cancer.
Pear has a lot of effects on human body, such as promoting the secretion of saliva or body fluid, quenching one's thirst, clearing heat, eliminating phlegm, etc. In the traditional Chinese medicine, it is always used to cure esophagus, cardia cancer and stomach cancer. Because pear contains a lot of carotene, vitamin B2 (riboflavin) and vitamin C, all of which have certain effect in the prevention and treatment of cancer, so it is suitable for the patients who suffer from laryngeal cancer and lung cancer.
