Which vegetables can the elderly eat to fight cancer?

　　Vegetables are naturally indispensable in people's daily meals. They are not only an important source of nutrients needed by the human body, but also ensure that the human body healthy an indispensable and important material basis. This article introduces the anti-cancer ingredients in vegetables.

　　Rich in chlorophyll

　　Recently, domestic and foreign researchers have used the advanced SOS color test to conduct research on anti-mutation foods. Researchers tested more than 30 kinds of fresh vegetables, such as ginger, bamboo shoots, garlic, etc. Among them, leeks, garlic, and leeks had the strongest effect, and the SOS reaction was inhibited, indicating that these vegetables have anti-mutagenic effects, and the water-soluble extracts are closer to living conditions, so they have greater anti-cancer significance.

　　Interferon inducer

　　Experts from the Institute of Virology of the Chinese Academy of Preventive Medicine spent six years finally uncovering the secret of vegetables' anti-cancer properties - they contain interferon inducers. Luffa and raw melon from the Cucurbitaceae family ； Carrots, white radish, and green radish from the genus Radish to carrots from the family Umbelliferae all contain interferon inducers, which can prevent oral cancer, esophageal cancer, stomach cancer and nasopharyngeal cancer, the above-mentioned vegetables rich in interferon inducers can be eaten raw.

　　Large amounts of sulfur compounds

　　Vegetables rich in sulfur compounds include onions, onions, and garlic from the Liliaceae family, and radish, cabbage, cabbage, and turnips from the Cruciferous family. Cruciferous vegetables contain natural inhibitors of cancer cells such as indole compounds and aromatic thiocyanate. Consuming more cruciferous vegetables is helpful in preventing and treating cancers unique to women. disease It has certain preventive and therapeutic effects.

　　sitosterol

　　According to New York Sloan? Scientific experiments at the Kettering Memorial Cancer Research Center have proven that sitosterol, a major component in vegetables, has the effect of preventing and treating tumor formation.

　　amylase and tomato red pigment

　　Japanese scientists have discovered that radish contains an "amylase" that can detoxify strong carcinogens such as nitrosamines and benzopyrene, causing them to lose their carcinogenic effects and have a significant anti-cancer effect. In addition, lettuce, peas, bean sprouts, pumpkin, etc. also contain an "enzyme" that can decompose the strong carcinogen nitrosamines and effectively prevent cancer. According to scientific research in the United States, eating more tomatoes can reduce the incidence of prostate cancer and pancreatic cancer in men. The anti-cancer effect of tomatoes mainly contains lycopene, which interferes with molecules in the human body that damage the genetic material DNA and cause cancer.

　　carotene

　　Taking carotene preparations can prevent gastric cancer, lung cancer, breast cancer and brain swelling, etc. cancer The incidence rate dropped by 1/2 to 2/3. Lack of carotene or vitamin A in the body can cause esophageal cancer, gastric cancer, lung cancer and other cancers. Vegetables rich in carotene include carrots, large peppers, spinach, leeks, bamboo shoots, alfalfa, coriander, etc.

　　B vitamins

　　Among the B vitamins, vitamin B2, vitamin B6, vitamin B12 and folic acid all have anti-cancer effects. Reducing the toxicity of chemical carcinogens in the body requires the participation of vitamin B2. Eating more foods containing vitamin B2 can prevent and treat liver cancer. Vegetables containing vitamin B2 include fresh green leafy vegetables, seaweed, mushrooms and fresh beans. Folic acid and vitamin B12 deficiency are important factors in the high incidence of esophageal cancer. According to epidemiological surveys, folic acid deficiency can also lead to cervical cancer , colon cancer, rectal cancer, brain tumors and other cancers, the main vegetables containing folic acid are spinach, celery, cabbage, leeks, cabbage, cauliflower, lettuce, etc.

　　Vitamin C

　　Vitamin C can improve immune function, fight and eliminate cancer cells, inhibit cancer cells and cancer-causing viruses by promoting the synthesis of interferon, 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 cabbage, rape, alfalfa, cauliflower, bitter melon, pepper, edamame, lettuce, etc.

　　Vitamin D

　　Researchers at the University of Pittsburgh have found that supplementing large amounts of vitamin D can inhibit metastatic prostate cancer in experimental mice. This discovery provides a new way to prevent and treat human prostate cancer. Previous studies conducted by scientists have found a certain link between vitamin D and prostate cancer, but this is the first time that experiments have shown that vitamin D has a certain inhibitory effect on the spread of prostate cancer. Vegetables with higher vitamin D content include leeks, garlic, onions, soybeans, coriander, white radish, celery, seaweed, potatoes, as well as various animal livers and fish.

　　Cellulose

　　The rich cellulose contained in vegetables is a carbohydrate that cannot be absorbed by the human body. It is mainly composed of plant fiber, pectin, glue and lignin. Its existence induces the proliferation of beneficial bacteria in the intestines, can combine with toxic substances in the intestines to promote their elimination from the body, and shorten the poisoning of the intestines by toxic substances. The lignin in cellulose can increase the activity of macrophages that phagocytose bacteria and cancer cells in the body by 2 to 3 times, thereby effectively preventing the occurrence of cancer.

　　Allicin and polyacid ginsenotriol

　　Garlic has many anti-cancer ingredients. Garlic consumption is negatively correlated with gastric cancer mortality ； The sulfide compounds contained in garlic can competitively bind nitrite, block the synthesis of carcinogen nitrosamines, and have the effect of preventing and treating digestive tract cancer. ； Garlic extract boiled in hot water, right Uterus The suppression rate of neck cancer is 70% to 80%. According to Japanese scientific research, fresh ginger has anti-cancer effects. The reason is that fresh ginger contains the polybasic acid ginsenotriol, which can inhibit the spread of cancer cells.

　　polysaccharides

　　Research has confirmed that the bacteria in edible fungi Mushrooms , such as: white mushrooms, enoki mushrooms, straw mushrooms, white fungus and Hericium erinaceus, etc., all contain polysaccharides, which can inhibit the proliferation and division of human cancer cells, thus having obvious anti-cancer and anti-cancer effects.

　　Various trace elements

　　According to scientific research, trace elements such as selenium, molybdenum, iron, zinc and germanium all have the effect of preventing and treating cancer. Selenium can prevent carcinogens from combining with DNA in normal cells, inhibit the development of cancer lesions, and stimulate intracellular lysosome activity, so it can prevent cancer. Vegetables containing selenium include: garlic, Chinese cabbage, onions and pumpkins. If the human body is deficient in molybdenum for a long time, it is susceptible to esophageal cancer. When people ingest food, the carcinogen nitrosamines enter the human body. After long-term accumulation, it is easy to induce cancer. Molybdenum can block the production of nitrosamines in the body, inhibit the occurrence of esophageal cancer, reduce the absorption of carcinogens in the body and accelerate their excretion, and ensure that normal cell genetic factors are not invaded by carcinogens. Vegetables containing molybdenum include: Chinese cabbage, cabbage, radish greens, beef cabbage, etc.
