First, don't smoke or give up smoking. Half of smokers will die of smoking-related diseases, many of which are cancer. In the United States, 90% of lung cancer is directly caused by smoking, and another 3% is caused by inhaling second-hand smoke. Ferri said: "I don't know why people spend three to five dollars a day to help them live 8 to 12 years."
Second, pay attention to what you eat. The American Cancer Society suggests that people should eat at least five different vegetables and fruits every day, which is an effective way to help fight cancer. Nutrition and Cancer magazine also announced that people who seldom eat fruits and vegetables are twice as likely to get cancer as those who eat more fruits and vegetables. The American Cancer Society also suggests: choose whole wheat flour instead of refined wheat flour, limit the consumption of red meat, especially eat less processed and high-fat meat, limit alcoholic beverages, and so on.
Third, do more exercise. Moderate exercise is the exercise mode recommended by scientists. According to research, walking for an hour every day can reduce the possibility of colon cancer by 46%. The American Cancer Society advises people to do at least 60 minutes of moderate or slightly intense exercise every day and exercise more than five times a week. Ferri added that obesity can also increase the possibility of cancer.
Fourth, understand the family history. Family history is the biggest cause of fatal cancer, and heredity may lead to carcinogenic factors in genes. If immediate family members (parents, siblings, children) have had cancer, then you may need to have regular checkups at a younger age.
But in any case, people should not be afraid, but should take a positive attitude to prevent cancer.
Food for preventing cancer
1) Milk and yogurt milk contain calcium and vitamin D, which can combine with carcinogens in the intestine to eliminate their harmful effects. Yogurt can inhibit the growth of tumor cells.
2) Honey and bee milk honey can promote metabolism, enhance the body's resistance, improve hematopoietic function and tissue repair. In recent years, it has been found that bee milk contains special bee lactic acid, which is effective in preventing and treating malignant tumors.
3) Tea contains catechins, which can remove radioactive substances from the body. Regular drinking tea for radiotherapy patients is beneficial to their recovery. Tea can also prevent dental caries.
4) The effect of pollen food is to improve intelligence, promote development, enrich blood, increase endurance, delay aging, have hormone-like effects and enhance disease resistance.
5) Vegetables Fresh vegetables, such as carrots, radishes, preserved fruits, eggplants and cabbages, contain interferon inducers, which can stimulate cells to produce interferon. This substance can enhance patients' resistance to diseases and cancers. But it is easily damaged by heating, so the above. Food should be eaten raw. Many studies have confirmed that garlic has anti-cancer ability, and the fat-soluble volatile oil in garlic can activate macrophages and improve the anti-cancer ability of the body. It also contains a sulfur-containing compound, which also has the effect of killing tumor cells. Onion can also resist cancer, probably because it contains glutathione and various vitamins. It has defensive effects on lymphoma, bladder cancer, lung cancer and skin cancer.
6) Seafood can be used as therapeutic food for patients with malignant tumor. The effective components of seaweed are mainly polysaccharide and sodium alginate. Sodium alginate can combine with radioactive strontium and be excreted. Eating kelp, seaweed and other foods often is good for your health. Shark cartilage can inhibit tumor growth, and shark fin has the ability to inhibit tumor infiltration around. Fish is rich in inorganic salts such as selenium, zinc, calcium and iodine, which is also beneficial to anti-cancer.
7) Fungal food contains polysaccharide and interferon inducer, which can inhibit tumor. Mushrooms have certain curative effects on gastric cancer, esophageal cancer, lung cancer and cervical cancer. Flammulina velutipes also has the same effect and has an inhibitory effect on tumors. Hericium erinaceus has curative effect on gastric cancer, which can prolong the survival time of patients and improve immunity. Tremella fuciformis has inhibitory effect on cancer. In recent years, it has been found that 90% of B-pachyman in Poria cocos can enhance immune function and has anti-cancer effect.
8) Fruit almond can improve the immune function of the body and inhibit cell canceration. It can relieve symptoms such as xerostomia, but it is not suitable for patients with inflammation, ulcer and nosebleed. Mume also has anti-cancer effect, and jujube can inhibit the growth of tumor cells. Fig extract can be used to treat gastric cancer, throat cancer, cervical cancer, bladder cancer, etc. Apple contains a lot of pectin, which can be combined with radioactive elements to promote its discharge. Papaya can prevent the spread and development of cancer.
9) Steroids extracted from other sweet potatoes can inhibit the development of breast cancer. Corn flour can inhibit tumor growth and reduce the side effects of anticancer drugs. The polysaccharide and coix lachryma-jobi fat in coix lachryma-jobi seed can enhance immune function and inhibit tumor cells.
Prevention of cancer, how to eat?
(1) Food diversification: A wide range of recipes can not only meet various nutrients needed by the body, but also inhibit harmful carcinogens.
(2) Drinking alcoholic beverages must be moderate: drinking more is harmful to health, and cancers of the mouth, throat, esophagus and liver are related to excessive drinking. People who drink too much and smoke at the same time are at greater risk of cancer.
(3) Avoid excessive cholesterol intake: A low-fat diet can reduce the risk of breast cancer, prostate cancer, colon cancer and rectal cancer.
(4) Eat foods containing enough starch and cellulose: you should eat more fruits, vegetables, dried beans, whole grains, beans and their products. To increase the intake of starch and cellulose, which can reduce colon cancer and rectal cancer.
(5) Keep the balance of nutrition and maintain the ideal weight. Avoid eating too much sugar.
Diet to prevent cancer 14 method
Cancer is the biggest enemy of human health at present. Every year, about 6 million people in the world are killed by cancer, of which about1300,000 people in China die of cancer. However, cancer can be controlled. The World Cancer Research Foundation has devoted itself to the basic, clinical and cancer prevention research of cancer for many years, summed up the research results in the field of cancer all over the world, and put forward 14 suggestions for preventing cancer from diet and health with broad scientific basis. Excerpts are as follows:
Suggestion 1: Arrange your diet reasonably. Plant foods, such as vegetables, fruits, cereals and beans, should account for more than 2/3 in the daily diet.
Recommendation 2: Control your weight and avoid being too light or too heavy. Weight gain in adulthood should not exceed 5 kg. Measured by the body mass index (BMI) formula. (see formula)
Weight (kg)
BMI＝——————————————
Height (m) × height (m)
BMI less than 20, underweight; BMI is 20 ~ 25, which is the ideal weight; BMI is 25 ~ 30, slightly overweight; BMI greater than 30, seriously overweight.
Recommendation 3: Stick to physical exercise. If you have little or only light activity at work, you should have a brisk walk or similar exercise every day for about 1 hour. Do at least 1 hour strenuous activity of sweating every week.
Recommendation 4: Eat more vegetables and fruits. You should eat 400 ~ 800 grams of fruits and vegetables every day. Green leafy vegetables, carrots, potatoes and citrus fruits have the strongest anti-cancer effect. Eat more than five kinds of fruits and vegetables every day, and stick to it all the year round, so as to have a continuous anti-cancer effect.
Recommendation 5: Eat 600 ~ 800g of all kinds of cereals, beans and plant roots every day, and the less processed food, the better. Eat less refined sugar.
