1, vegetables rich in vitamin C: Vitamin C also receives ascorbic acid, which is closely related to human health, especially its anticancer effect is well known. Vitamin C can prevent the formation of carcinogenic nitrosamines and inhibit the proliferation of cancer cells.
Vegetables rich in vitamin C include tomatoes, Chinese cabbage, Chinese cabbage, rape, cabbage, amaranth, spinach, celery, garlic sprouts and green onions.
2. Vegetables rich in vitamin A: Carrots are the most striking anti-cancer vegetables. Carrots are rich in anti-cancer substance carotene. Carotene is a natural nontoxic anticancer substance. Carotene can reduce inflammation of epithelial tissues such as throat, esophagus and gastrointestinal tract, prevent cell mutation caused by carcinogens, and thus inhibit precancerous lesions of some tissues. Carotene is the main component of vitamin A,
Dried pepper, Chinese cabbage, pumpkin, rape, cocoon, spinach, leek and celery leaves rich in vitamin A have anti-cancer effects.
3, cauliflower, cabbage, lettuce, radish: According to the American Cancer Society, cauliflower and cabbage can prevent cancer, and eating these vegetables often can reduce the chance of some cancers. Cauliflower and cabbage are rich in dithizone, which can prevent cancer. These two kinds of vegetables also contain trace amounts of molybdenum, which can block the synthesis of oxynitramine, so they have anti-cancer effects.
Lettuce and radish contain an enzyme that can decompose ammonium nitrite and prevent the action of carcinogens.
4. Garlic: "Study on garlic blocking nitrosamine synthesis" proves that garlic can block nitrosamine synthesis in many ways; At the same time, direct contact between garlic and garlic can also kill gastric cancer cells, which shows its anticancer effect.
5. Kelp: Kelp is also called kelp. Kelp has anticancer effect, probably because it contains more fiber, which promotes the excretion of carcinogens in the intestine. In addition, kelp contains high calcium content (1000g kelp contains 1000 ~ 3000 mg). According to epidemiological investigation, the incidence of colorectal cancer is obviously reduced by eating foods rich in calcium.
Which vegetables have anti-cancer effects?
garlic
Garlic contains protein, fat, sugar, calcium, phosphorus, iron, zinc, selenium, copper, magnesium, vitamin C, B 1, B2 and so on. In addition, there are allicin (also known as plant bacteriocin) and germanium. According to the analysis, the content of germanium in garlic is higher than that of any plants containing germanium, and the content of selenium is also higher. Germanium and selenium are both indispensable substances for human anti-cancer, especially for digestive tract cancer, garlic is their nemesis.
onion
Scientists have found that onion contains a substance-selenium, which is an antioxidant. It has a special function, that is, it can make the human body produce a lot of glutathione. Glutathione is composed of glutamic acid, methionine and glycine, and its main function is to transport oxygen for cells to breathe. When the concentration of this substance increases, the incidence of cancer will be greatly reduced.
cabbage
Modern medicine has found that cabbage contains vitamin U-like factor, which is found in all green vegetables, but it is the most abundant in cabbage, and its effect is better than that of synthetic vitamin U. Therefore, fresh cabbage juice has analgesic and healing effects on gastric and duodenal ulcers. Scientists believe that cabbage contains enzymes that can decompose nitrosamines and can eliminate the mutation of nitrosamines. Therefore, Chinese cabbage has a certain anti-cancer effect.
sweet potato
Sweet potato is rich in dietary fiber, which is beneficial to excretion and has the function of detoxification and beauty. Foreign research results also show that a substance called "dehydroepiandrosterone" contained in sweet potato has a certain effect on preventing cancer.
Leaf mustard
Although mustard has never been to Yatang, its value is not low. It contains provitamin A, which people attach great importance to. Therefore, adding a plate of mustard to every meal can not only adjust the taste and help people supplement vitamin A, but also help treat diseases caused by vitamin A deficiency and prevent cancer.
carrot
Carrots contain a lot of provitamin A. The research results at home and abroad indicate that vitamin A may indeed become an effective anticancer substance, which has a preventive effect on esophageal cancer, lung cancer and uterine cancer.
soybean sprout
After soybean germination, many original nutrients increased greatly, such as vitamin B2 increased by 2-4 times, carotene increased by 2-3 times, and vitamin B 12 increased by more than 10 times. More ideally, bean sprouts do not contain cholesterol, and chlorophyll in bean sprouts can prevent and treat cancers such as rectal cancer. Eating bean sprouts regularly can eliminate carcinogens in the body and prevent cancer.
tomato
Lycopene in tomato is an antioxidant, which can eliminate some carcinogenic oxygen free radicals. Researchers at Johns Hopkins University pointed out that if the body lacks lycopene, it is easy to get pancreatic cancer. People with extremely low levels of lycopene in their blood have more than five times the risk of pancreatic cancer.
