Cancer is the second biggest killer of people, after cardiovascular and cerebrovascular diseases. Currently, there is no specific cure for cancer. Therefore, cancer prevention is more important than cancer treatment. Research has found that improper diet can cause cancer, and proper diet can prevent cancer and cancer. So, which foods can prevent cancer?
Animal anti-cancer food
1. Fish oil: research has found that the eicosapentaenoic acid contained in fish oil has anticancer effect. This substance is a polypolyunsaturated fatty acid. It mainly exists in the oily fish oil, such as sardine oil, herring oil, salmon oil and so on. Studies have shown that when tumor cells break down the body’s fat tissue and proteins, they produce a tumor factor that promotes tumor growth. And the eicosapentaenoic acid in fish oil can stop the activity of this tumor factor, thus preventing tumor growth.
Fish scales: immunologists have shown that fish scales play an important role in cancer. If the white blood cells in fish phosphorus were implanted into the mice with cancer, the tumor cells would disappear. The cancer drug, guanine sulfide, is made from fish scales, and is more than 70 percent effective in treating leukemia.
Beef: a team of microbiologists has found that beef contains an ingredient that inhibits the mutagenesis of carcinogens. Therefore, beef has anticancer effect. The team is trying to extract new anti-cancer drugs from beef.
Sheep foetuses: scientists have found that liver cells in sheep foetuses contain cancer-fighting substances that activate the body’s immune system. The scientists injected human cancer cells into the mice, and then purified sheep embryo essence into the mice. The results showed that sheep embryo essence can inhibit the growth of cancer cells. Scientists believe that sheep embryo essence will open a new way to treat lung cancer, liver cancer, leukemia and other diseases.
Mulberry silkworm: studies have found that using one silkworm can produce hundreds of medical doses of experimental anticancer agents. A Japanese company claims that by swapping a gene in a silkworm, it produces interferon, which is identical to the interferon produced in humans. Therefore, it is possible to extract new anticancer drugs from silkworm.
Plant-based cancer-fighting foods
1. Date: in recent years, hot water extract of date has been found to have an inhibitory effect on tumor cells cultured in vitro, with a inhibition rate of up to 90%. But the extract also has a slight inhibitory effect on normal cells. This inhibition is related to the dose of the extract. The anticancer effect of jujube is related to the abundance of cyclic adenosine phosphate and vitamin in jujube.
2. Sour plum: the fruit of sour plum contains effective substances such as malic acid, citric acid, succinic acid, quercetin, waxy alcohol and triterpene. Animal experiments have shown that these components can enhance the ability of white blood cells to ingest toxic substances in mice, improve the immune function of mice, and have a certain inhibitory effect on subcutaneous sarcoma of mice. Therefore, it can be used as an adjunct to the treatment of diseases such as cervical cancer.
Tomatoes: the lycopene found in tomatoes has an anticancer effect. Lycopene is an antioxidant. It’s found in tomatoes, watermelon and almonds, and it fights off cancer-causing oxygen radicals in the body. People who have too little lycopene in their blood can greatly increase their risk of developing pancreatic cancer. The study found that people with low levels of lycopene in their blood were five times more likely to develop pancreatic cancer.
Garlic: garlic contains many anti-cancer compounds. Animal studies have shown that these anticancer substances can inhibit carcinogens linked to organs such as the colon, stomach, liver and lungs. A study at the university of Pennsylvania found that mice fed garlic extract reduced their risk of breast cancer by 71 percent. Not long ago, German scientists found that garlic contains allicin that is toxic to malignant tumors. Garlic also inhibits the growth of cancer cells by increasing the body’s immune function. Studies have also shown that sulphide in garlic enhances the anticancer activity of macrophages and T lymphocytes.
Radish: radishes contain mustard oil. Mustard oil is the source of its pungent flavor. The enzyme in mustard oil and radish can interact with each other, which can promote gastrointestinal peristalsis, increase appetite and help digestion. In recent years, studies have found that radishes can fight cancer. The reason is that radishes contain many enzymes which can eliminate the carcinogenic nitrosamine in human body. The lignin in turnip can improve the vitality of macrophages, so that macrophages can phagocytosis cancer cells.
Rice bran: rice bran contains a polysaccharide called RBS. It could become an immune drug to prevent cancer cells from proliferating. The new substance, RBS, was extracted from rice bran by Japanese scientists using boiled water. They remove fat, starch and protein from rice bran and then precipitate “RBS” with alcohol. The researchers gave the new drug to mice with lung and skin cancer, and found that “RBS” improved the immune system of mice, which was better than existing cancer drugs.
Wheat bran: eating wheat bran can reduce your risk of colon cancer. A New York study showed that people with precancerous colon polyps who ate 2 ounces (1 ounce =28.3495 grams) of wheat gluten a day for six months reduced their precancerous colon polyps. Such a small amount of wheat gluten could play such a prominent role in such a short period of time, suggesting that wheat gluten has a better role in preventing cancer development.
8. Soya beans: more and more research results show that soya beans have an anti-cancer effect, especially for the prevention of breast, colon, rectal and esophageal cancer. An animal experiment at Alabama state university in the United States found that as little as 5 percent of soy in the diet significantly inhibited the risk of breast cancer in rats. A study by Cincinnati children’s hospital found that post-menopausal women who ate soy and its products had a beneficial effect on their endocrine systems, which may help prevent breast cancer. A harvard study found that regular tofu consumption reduces a person’s risk of colon cancer by 50 percent. The national cancer institute is looking for cancer-fighting factors in soy. They have found five anti-cancer compounds in soy in animal studies. In addition, the fermentation preparation of soybean dregs, compound riboflavin (vitamin c), can prevent and treat esophageal epithelial hyperplasia and reduce the incidence of esophageal cancer.

Vegetable anti-cancer food
The national institute of cancer prevention in Japan recently conducted a statistical survey on the relationship between the dietary habits of 260,000 people and cancer. Through the analysis of anti-cancer components and anti-cancer experiments on more than 40 vegetables, the results confirmed that 20 vegetables had significant inhibitory effect on tumor cells. They are: cooked sweet potatoes, raw sweet potatoes, asparagus, broccoli, cabbage, celery, celery, eggplant skin, sweet pepper, carrot, yellow cabbage, mustard, pie (sound) blue, mustard, tomato, garlic, green onion, cucumber, cabbage, etc.
In conclusion, reasonable diet, attention to nutrition match, eat less Fried food, smoked and baked food, salted food, moldy food and food containing additives, coupled with smoking alcohol, regular exercise, can certainly prevent the occurrence of cancer or prevent the development of cancer.
