anti-cancer ingredients of vegetables: Vegetables with high sulfur compounds:
vegetables with high sulfur compounds: green onion, onion, garlic of Liliaceae, white radish, cabbage and turnip of Cruciferae, etc. For example, cruciferous vegetables contain indole compounds and aromatic thiocyanate and other natural inhibitors of cancer cells. According to the experimental research of American scientists, dithiolone, which is rich in cruciferous vegetables, has anticancer effect. It was confirmed by animal experiments that taking thiophene thioketone compound could significantly reduce the incidence of gastric cancer and lung cancer induced by benzopyrene. According to the American Institute of hormone research, Chinese cabbage contains indole -3- formaldehyde compounds, which can break down the estrogen associated with breast cancer, so eating Chinese cabbage frequently can prevent breast cancer. The experts also suggested that women should eat more cruciferous vegetables, which has a certain preventive and therapeutic effect on the prevention of cancer diseases unique to women.
: contains & beta- Sitosterol
according to the research of a cancer research center, beta is a major component in vegetables- Sitosterol has the function of preventing and treating tumor formation. When the animals were fed with & beta containing 0.2%- The growth of colonic epithelial cells in rats fed with sitosterol was 50% lower than that in the control group. In addition, according to the experiment, the animals were fed with carcinogen nitrosamines first, and then with & beta- Among them, only one third of the animals developed cancer, while more than half of the animals in the control group developed cancer.
anti cancer ingredients of vegetables: abundant chlorophyll has anti mutation effect
recently, researchers at home and abroad used advanced SOS color test to study anti mutation food. SOS reaction is a kind of repair function with error tendency when RNA is damaged or DNA replication is blocked in cells. SOS color reaction test can quickly and effectively detect the degree of mutation or anti mutation of food. More than 30 kinds of fresh vegetables, such as ginger, green pepper, onion, potato, celery, carrot, spinach, cauliflower, white radish, mushroom, lettuce, broad bean, leek, soybean sprout, Chinese toon, shepherd’s purse, tomato, bamboo shoot and garlic, were selected for SOS test. The results showed that the acetone extracts of most vegetables had anti SOS reaction, It may be related to chlorophyll; The water-soluble extracts of garlic, leek, leek, soybean sprout, tomato and other 10 kinds of vegetables can inhibit the SOS reaction, among which leek, garlic and leek have the strongest effect, and the SOS reaction is inhibited, suggesting that these vegetables have anti mutation effect, and the water-soluble extracts are closer to the living conditions, so the anti-cancer significance is greater.
anti cancer ingredients in vegetables: containing amylase and lycopene; Amylase;, It can relieve the toxicity of strong carcinogens such as nitrosamine and benzopyrene, and make them lose the carcinogenic effect. In addition, lettuce, peas, bean sprouts, pumpkins and so on also contain a & lt; Enzymes;, It can decompose strong carcinogen nitrosamine and effectively prevent canceration. In addition, according to American scientific research, eating more tomatoes can reduce the incidence rate of prostate cancer and pancreatic cancer in men. The results showed that people who ate tomatoes more than 10 times a week had a 45% lower risk of prostate cancer than those who did not. Lycopene is the main anti-cancer component of tomato. It interferes with the molecules that destroy DNA (deoxyribonucleic acid) and lead to cancer.
anti cancer ingredients of vegetables: containing interferon inducer
experts from the Institute of Virology, Chinese Academy of preventive medical sciences have finally uncovered the mystery of anti-cancer of vegetables in six years& mdash; Containing interferon inducer. Interferon inducers can induce and stimulate cells to produce interferon, enhance the body’s resistance to antiviral infection and inhibit the proliferation of cancer cells. From Luffa, snakegour and bottle gourd of Cucurbitaceae, carrot, white radish and green radish of radish genus to carrot of Umbelliferae, all contain interferon inducer. In order to prevent oral cancer, esophageal cancer, gastric cancer and nasopharyngeal cancer, we can eat the above vegetables rich in interferon inducer raw as far as possible.
: B vitamins
in B vitamins, B2, B6, B12 and folic acid have anti-cancer effect. Vitamin B2 is necessary to reduce the toxicity of chemical carcinogens in vivo. According to experimental studies, eating more food containing vitamin B2 can prevent and treat liver cancer. Vegetables containing vitamin B2 include: fresh green leafy vegetables, laver, mushrooms and fresh beans. Folic acid and vitamin B12 deficiency are important factors of high incidence of esophageal cancer. For example, Yangcheng County in Shanxi Province is a high incidence area of esophageal cancer. According to a large number of investigations and tests by experts of Shanxi Medical College, the overall levels of serum folate and vitamin B12 in the population of this county are obviously low. Therefore, prevention of folic acid and vitamin B12 deficiency is one of the measures to prevent esophageal cancer. In addition, according to epidemiological investigation, lack of folic acid can also lead to cervical cancer, colon cancer, rectal cancer and brain cancer. The main vegetables containing folic acid are spinach, celery, cowhide, leek, cabbage, cauliflower, lettuce, etc.
: contains & beta- Carotene
, under the leadership of Professor Bu Jin of cancer inhibition Laboratory of Russian cancer research center, has been studying & beta- The effect of carotene on cancer was studied. The results confirmed that taking & beta- Carotene preparation can reduce the incidence rate of cancer, such as stomach cancer, lung cancer, breast cancer and brain tumor, from 1/2 to 2/3. If the body lacks beta- Carotene or vitamin A can cause esophageal cancer, gastric cancer, lung cancer and other cancers. According to the epidemiological survey in the United States, Japan, Iran and North China, the incidence of esophageal cancer is related to insufficient intake of vitamin A, and the patients with low vitamin a content have a higher risk of cancer. Rich in & beta- Carotene vegetables include carrot, pepper, spinach, leek, rape, cabbage, celery, tomato, bamboo shoot, alfalfa and coriander.
anti cancer ingredients of vegetables: cellulose
the rich fiber in vegetables is a kind of carbohydrate that can not be absorbed by human body. It is mainly composed of plant fiber, pectin, mucilage and lignin. According to the analysis of 13 cases of colon cancer and rectal cancer, the researchers found that cellulose in vegetables has a significant role in preventing colon cancer and rectal cancer. The reason is that the existence of cellulose induces a large number of beneficial bacteria in the intestine, which can be combined with toxic substances in the intestine to promote their excretion, thus shortening the toxicity of toxic substances to the intestine and lignin in cellulose, It can increase the activity of macrophage phagocytizing bacteria and cancer cells by 2-3 times, so as to effectively prevent the occurrence of cancer.
vegetable anti cancer ingredient: vitamin C
according to epidemiological investigation, the intake of vitamin C in residents with high incidence of esophageal cancer and gastric cancer is relatively low. If vitamin C intake is high, the incidence rate of esophageal cancer and gastric cancer is low. Vitamin C can improve the immune function, fight against and eliminate cancer cells. By promoting the synthesis of interferon, it can inhibit cancer cells and cancer viruses, eliminate the synthesis of foreign carcinogens in the body, and effectively prevent the occurrence of laryngeal cancer, esophageal cancer, gastric cancer, liver cancer and cervical cancer. Vegetables containing vitamin C mainly include: pakchoi, rape, amaranth, green garlic, alfalfa, cauliflower, balsam pear, pepper, soybean, carrot, white radish, lettuce, etc.
anti cancer ingredients of vegetables: vitamin d
researchers from the University of Pittsburgh found that a large amount of vitamin D supplementation can inhibit metastatic prostate cancer in experimental mice. This discovery provides a new way for the prevention and treatment of human prostate cancer. Professor Ben Wright of the University of Pittsburgh Center said in the research report that he and his colleagues transplanted highly metastatic prostate cancer cells into some experimental mice and then divided them into two groups. One group received vitamin D for three weeks and the other group received no treatment. The results showed that the volume of tumor in one group of mice injected with vitamin D was 88% smaller than that in the other group, the number of tumor transferred to the lung was 75% less, and the volume of lung tumor was 85% smaller. Previous studies by scientists have found that vitamin D in the blood of some patients with prostate cancer is low, which indicates that vitamin D has a certain relationship with prostate cancer. However, it is the first time that vitamin D has a certain inhibitory effect on the proliferation of prostate cancer. The varieties with high vitamin D content in vegetables are leek, garlic, onion, soybean, coriander, white radish, celery, seaweed, potato and so on.
