For a long time, vegetables have been considered as an important source of vitamins and trace elements. In recent five years, scientists have been surprised to find that the compounds previously considered harmful in vegetables have anti-cancer properties. Subsequently, medical experts advised people to eat more vegetables rich in carotene, such as carrots, broccoli, broccoli and spinach.
1995 American biologists found that sweet potato contains a chemical called hydroepiandrosterone, which can be used to prevent colon cancer and breast cancer; From 65438 to 0996, the National Anti-Cancer Institute of Japan investigated the relationship between diet and cancer of 260,000 people, which proved the anti-cancer effect of vegetables. According to the analysis of anti-cancer components of more than 40 kinds of vegetables and the results of anti-cancer experiments, 20 kinds of vegetables with significant anti-cancer effects were arranged from high to low, in the order of cooked sweet potato 98.7%, raw sweet potato 94.4%, asparagus 93.7%, cauliflower 92.8%, Chinese cabbage 9 1.4%, cauliflower 90.8% and coriander 83.7%. Cauliflower 37.6%, shepherd's purse 35.4%, kohlrabi 34.7%, mustard 32.4%, potherb mustard 29.8%, tomato 23.8%, onion 16.3%, garlic 15.9%, cucumber 65433.
A study on anti-cancer vegetables conducted by British scientists at the beginning of 1997 showed that broccoli and Brussels sprouts are rich in auxiliary compounds of glucose isothiocyanate, and radish has been decomposed from glucose isothiocyanate, and DNA substances with radish growth genes have been isolated from broccoli. Transplanting this substance into various cabbages and radishes (hope to succeed soon) will help to enhance people's resistance to cancer cells and reduce the risk of cancer. However, Brussels sprouts have different anticancer functions from radish. The anticancer effect of sprouts is glucosinolates, which can hinder the growth of early cancer cells.
Scientific experimental analysis shows that the anticancer activity of cooked sweet potato ranks first in vegetables, surpassing that of ginseng. Among vegetables that people often eat, lycopene contained in tomatoes is an antioxidant, which can inhibit some carcinogenic oxygen free radicals. Dark green vegetables such as spinach and celery are rich in antioxidants. The deeper the green, the stronger the anti-cancer effect. Irritating vegetables such as onions and garlic contain a lot of chemicals that inhibit the growth of cancer.
Japanese scholars have found that the spicy ingredients of ginger have a strong antioxidant effect on fatty foods such as meat and fish. Compared with the antioxidants BHA, BHT and vitamin E currently used, the spicy components of ginger have more effective antioxidant effects. Analysis shows that capsaicin in spicy vegetables can inactivate a chemical called "DMN", which can prevent the canceration process of related cells. It is a potential anticancer substance, so it has great temptation. Vegetables such as water bamboo and celery are rich in fiber, which can speed up the emptying of chyme in the intestine, shorten the residence time of toxic substances in food in the intestine, promote bile acid excretion, and keep feces acidic, which is very beneficial to prevent colorectal cancer. Eating carrots, carrots, amaranth and other red vegetables can increase coronary blood flow, reduce blood lipids and enhance human resistance.
Returning to nature and being green and pollution-free have become the remarkable characteristics of vegetable production in 2 1 century. After quick-frozen vegetables, canned vegetables and dehydrated vegetables, new varieties such as pink vegetables, juice vegetables, beauty vegetables, spicy vegetables, instant vegetables and vegetable vaccines have appeared, among which anti-cancer vegetables developed and produced are favored by people.
"Hearing cancer" should be "pancreatic cancer".
Please develop good living habits to prevent pancreatic cancer.
Pancreatic cancer has a great relationship with lifestyle, and it is also a kind of "lifestyle cancer". The so-called "lifestyle cancer" is the cancer caused by unhealthy food, clothing, housing and transportation: smoking, drinking late at night, breathing the exhaust of cars in busy streets and even inhaling fumes and fog when cooking at home are all likely to cause cancer. Work pressure, irregular life, long-term entertainment will damage people's health. The incidence of pancreatic cancer in people with high-fat diet and diabetes is significantly higher than that in other people. Eating smoked, fried and pickled foods at home will increase the risk of pancreatic cancer; The increase in the consumption of edible oil and high-salt food will not only lead to hypertension and cardiovascular diseases, but also easily lead to the hidden danger of pancreatic cancer.
The key to prevent pancreatic cancer is to develop good living habits;
First of all, we should adjust the diet structure to prevent cancer. If you don't eat burnt and charred food, try to eat less foods with high fat, oil and salt, which can reduce the incidence of pancreatic cancer by more than two thirds. To prevent cancer, coarse grains such as cereals, beans and sweet potatoes should be the main body of the diet. Fresh vegetables and fruits are essential every day, and fiber, carotene, vitamin E and essential minerals are added to the diet.
Secondly, take part in appropriate sports activities, avoid overweight and obesity, and control the intake of animal foods and oils such as meat. Drink alcohol in moderation, control salt intake, pay attention to the law of life, greatly reduce entertainment, and resolutely put an end to overeating. Eat lightly, don't overeat.
Third, life should be regular. Some people are busy with work, eat three meals a day casually and overeat on holidays. In this way, it will cause indigestion, abdominal distension, acute pancreatitis and even life-threatening, which also lays a hidden danger for pancreatic cancer. It is believed that overeating in early life will promote development and maturity, and overeating after maturity will increase the occurrence of some degenerative diseases, thus shortening life expectancy. Therefore, limiting diet in moderation throughout life is the secret of longevity and the fundamental method to prevent "eating cancer".
Self-monitoring of pancreatic cancer
Patients aged 40 or above should be suspected of having pancreatic cancer if they have any of the following clinical manifestations:
① Obstructive jaundice.
② The recent unexplained weight loss exceeded 10%.
③ Recent unexplained upper abdominal or lower back pain.
④ recent unexplained dyspepsia and normal digestive tract.
⑤ Sudden onset of diabetes without family history, obesity and other factors.
⑥ Sudden unexplained fatty diarrhea.
All landowners spontaneous pancreatitis attack. If the patient is a smoker, he should be more suspicious.
