Nature has given us many weapons to fight against cancer. By using the foods that exist around us to fight against cancer, it is possible to reduce the incidence of cancer by 30-60%. The best foods to prevent and fight cancer are as follows: 1. Liver Liver is a treasure trove of vitamins, inorganic salts and other substances that can help inhibit cancer. In addition to a large amount of VB and nucleic acids, liver also contains a certain amount of selenium. In addition, liver contains a kind of substance called “anti-proliferator” which plays a special anti-cancer role and has the ability to hinder cell division and growth, which can have a significant inhibitory power on cancer. Therefore, liver is not only a kind of tonic but also a good anti-cancer food. 2.Food fiber Food fiber is the general name of some compounds in plant food, mainly including cellulose, hemicellulose, pectin, lignin and so on. Although it is not a human energy source, it is an essential functional component of human body. The metabolic properties of food fiber have significant effects on enhancing the function of the gastrointestinal tract, promoting the digestion and absorption of food and unblocking stools. Lignin can increase the viability of macrophages by 2 or 3 times, thus greatly enhancing their ability to engulf cancer cells. The role of consuming fiber to open the stool is to reduce the irritation and retention of certain ingested carcinogens and carcinogens caused by metabolites of food residues in the intestinal tract to avoid inducing digestive tract cancer. Eating drum sugar, for example, can prevent bacteria in the colon from turning bile salts into carcinogens. Recently, it has also been found that the metabolic payoffs of fiber-rich foods, namely fatty acids naturally produced during intestinal fermentation, can cause intestinal cancer cells to “kill themselves”. Investigation shows that people who often eat cereals, cruciferous vegetables and citrus, apples and other fiber-rich foods rarely suffer from colon and colorectal cancer, while those who specialize in eating refined rice, white flour, ignore fresh fruits and vegetables, and choose high protein and high fat as their food hobbies, are suffering from a “civilization disease” and are on a ” Food death” road. 3, yogurt and acetic acid drinks Yogurt or yogurt contains antiseptic and flavoring lactic acid and health benefits of lactic acid bacteria. On the one hand, lactic acid bacteria can inhibit intestinal corruption bacteria reproduction, stimulate gastric acid secretion, help digestion and lower blood lipids, can enhance the body’s resistance to infection and aging process, reduce blood cholesterol levels, help health care and longevity, on the other hand, especially valuable is the lactic acid bacteria in the rod-shaped lactobacillus culture synthesis of compounds have anti-cancer effects. Acetic acid drinks are now popular in various countries and have become the latest fourth generation of drinks after citric acid, cola and lactic acid types. The reason for this is that it is extremely rich in various nutrients such as amino acids, organic acids and trace elements. Since nitrogenous acid can act with nitrite as well as antioxidant ability, it has the effect of blocking nitrosylation and preventing and reducing lipid peroxidation in the body. It can detoxify and protect liver and avoid cancer. Shanghai people love vinegar and acetic acid drinks not without reason. 4.Sardines are rich in zinc and nucleic acid, and also contain inorganic salts with high nutritional value and favorable anti-cancer such as selenium and calcium. Regular consumption of seafood such as sardines rich in nucleic acid can stop the growth of cancer or make it smaller until it finally disappears by inducing cancer cells to reverse to normal cells through biologically active substances related to genetic information, such as normal information ribonucleic acid (mRNA). 5, asparagus is currently selling well in Europe and the United States market, known as a health food. Asparagus has special effect on high blood fat heart disease, high blood pressure arteriosclerosis and cancer. Taking asparagus is effective in treating eye cancer, lymphoma, bladder cancer, lung cancer, skin cancer and almost all cancers. This is because it is particularly rich in “histone”, which normalizes cells and effectively controls cell growth, as well as folic acid and nucleic acid, which have anti-cancer effects. Folic acid can normalize damaged DNA more quickly and also works in synergy with B12 to prevent DNA damage and help the bone marrow produce red blood cells. Garlic contains protein, fat, sugar, VB, VC and minerals such as calcium, phosphorus and iron, which are not only good for seasoning, but also have the most important pharmacological role in enhancing the body’s anti-cancer effect. It was found that the incidence of gastric cancer is low in regions and populations where garlic is a profession and vegetarian habit of eating garlic. This is because on the one hand, raw garlic can reduce the content of nitrite in the stomach, on the other hand, the allicin contained in garlic can stimulate gastric juice secretion, enhance appetite and help digestion, and also has a strong bactericidal effect. In particular, it has a certain inhibitory effect on the bacteria that produce nitrosamines, which can prevent the occurrence of stomach cancer and other cancers. In addition, garlic also contains the effective ingredient of fat-soluble volatile garlic essential oil that stimulates human macrophages to engulf cancer cells. This plant bactericidal element is effective in enhancing immunity and organism resistance, which can not only fight cancer but also make people live longer. 6, tea Contains nearly 40 kinds of chemical components, extremely rich in nutritional value, the components contained have very important physiological functions. In addition to anti-inflammatory and detoxification, tea contains vitamins A, B, C, E and trace elements key to interrupt the synthesis of nitrosamines in the body and prevent the occurrence and development of cancer cells, thereby reducing the incidence of esophageal cancer and stomach cancer. Therefore, regular consumption of tea can cure many diseases and prevent cell carcinogenesis in the whole body parts, and increase the function of white blood cells, which has a certain inhibitory effect on leukemia (blood cancer). The difference between cancer-causing and cancer-preventing is a million miles. Nutrition against cancer has a bright future. In order to prevent cancer, human beings still need to conduct more in-depth research on the mechanism of food anti-cancer, and constantly seek new and better anti-cancer foods.
