Health preservation: anti cancer diet should be "mixed three times a day" with vegetables and fish for each meal

According to Kang Jingxuan, omega-3 can inhibit the growth of cancer cells There are two kinds of fatty acids in human body Omega-6 and omega-3 are not synthesized by the body and can only be taken from food Omega-6 mainly comes from eggs, meat and oil products Omega-3 is found in fish and some nut foods In the process of cancer cell incubation, Omega 6 fatty acids constantly "fan" the pathogenic factors and promote the expression of cancer genes; Omega 3 fatty acids mainly kill cancer cells in the bud Cancer cells like the metabolites of omega-6 unsaturated fatty acids most, but they are afraid of the metabolites of Omega-3 Countermeasures: the lack of omega-3 in human body caused by dietary structure of "green, water and fish" three times a day can be realized by adjusting diet Dr Kang Jingxuan said there was no clear figure for the amount of omega-3 supplementation On the diet, you can add more vegetables, fruits and fish, which is referred to as "green water fish" Green vegetables: the best choice is fresh, pollution-free vegetables Chlorophyll and other substances in green vegetables can effectively reduce the toxicity of carcinogenic aflatoxin If it is difficult to ensure pollution-free, you can also try to increase the variety of green vegetables, such as spinach, broccoli, cabbage, etc., are rich in chlorophyll and folic acid Fruit: try to diversify, keep 2-3 kinds every day, and keep changing Research shows that there are more than ten kinds of fruits that can effectively reduce the risk of cancer, such as strawberry, apple, kiwi fruit and so on Fish: meat is mainly fish, supplemented by white meat such as chicken and duck The American Heart Association recommends that healthy adults eat at least two meals of fatty fish a week (deep sea cold water fish is preferred), preferably four times a week What to eat: "four more, three less" principle "balanced diet is the basis of cancer prevention diet." Xun Xiaolin, a senior nutritionist at the General Hospital of the Beijing Military Region, said that although living conditions are good, you can't eat what you want At present, the reasonable diet structure advocated is "two highs and one low": high vitamin, high cellulose and low fat Vitamins mainly come from fresh fruits and vegetables Cellulose exists in fruits and vegetables and coarse grains To control fat, it is necessary to eat less red meat such as pigs, cows and sheep, and replace it with white meat such as chicken and fish On this basis, we should try our best to ensure a diversified diet The simplest way is to count the colors It is best to eat five to seven colors of food a day The white food represented by onion, garlic, cabbage and cauliflower has a good anti-cancer effect; pay attention to the combination of thickness, millet, corn, oats and so on It is appropriate to eat 100g / day There are more than one hundred common anti-cancer foods, which are mainly divided into four categories "Eating more anti-cancer food can add to the picture." Ma Guansheng, deputy director of the Institute of nutrition and food safety, China Center for Disease Control and prevention, told reporters Fresh fruits and vegetables The antioxidants, carotenoids, vitamin C, flavonoids and other active ingredients contained in it have anticancer effect Yang Binghui, a famous health education expert and chief physician of Zhongshan Hospital Affiliated to Fudan University, praised the cancer prevention effect of fruits and vegetables: "the daily vegetable intake per person increased from 50g to 300g, and the risk of gastric cancer can be reduced by 50%." Asparagus, cabbage, tomato, sweet potato, konjac, kiwi fruit, radish and carrot are all good anti-cancer foods Bean products Tofu and soy milk are rich in soy isoflavones Regular consumption of soy products can reduce the risk of breast cancer, colon cancer and prostate cancer Fungi About 96% of bacteria have anti-cancer effect, such as mushrooms, mushrooms, Flammulina velutipes, agaric and other polysaccharide rich substances, which can enhance human immunity and prevent gastric cancer and lung cancer At present, lentinan has been used as an anticancer drug in the treatment of cancer patients Green tea Green tea is rich in tea polyphenols, which can be combined with carcinogens to decompose and inhibit the growth of cancer cells To develop the habit of drinking 2-3 cups of green tea every day can prevent gastric cancer, liver cancer and lung cancer, but it must be noted that the tea is not too thick "On the contrary, some foods are not good for cancer prevention, so we should eat less." Ma pointed out that the China Cancer Foundation has issued 10 suggestions for cancer prevention, among which 3 types of food are listed as forbidden areas of cancer prevention diet High energy food leads to obesity Foreign fast food and sugar drinks are typical small but high calorie foods If you don't pay attention to exercise after eating, it is easy to induce obesity Clinical studies show that 33% of cancers occur in obese people Chen Junshi, academician of the Chinese Academy of engineering and researcher of the Institute of nutrition and food safety of the Chinese Center for Disease Control and prevention, said vividly, "for every inch increase in people's waistline, the risk of cancer will increase more than eight times." Processed meat products induce cancer of the digestive system Salted fish, ham, sausages and other foods often contain higher nitrite, which will react with protein under the action of gastric acid and generate carcinogen nitrosamine, thus increasing the risk of esophageal cancer, gastric cancer, liver cancer and colorectal cancer Excessive drinking is closely related to liver cancer The China Cancer Foundation recommends that men drink no more than 20 to 30 grams of alcohol a day and women no more than 10 to 15 grams If you drink too much for a long time, it will lead to alcoholic liver, cirrhosis, and then liver cancer will come to you.
