In fact, cancer is a long process, and it will always occur for certain reasons and hints. Cancer prevention is never a matter of one person and never only benefits oneself, but the whole family should mobilize and live a long life, so let your family and friends learn it together! I. Authoritative research says that fruits can indeed prevent cancer In May 2016, the Harvard School of Public Health published a study in the top British medical journal: young girls who consumed 2.9 servings of fruit per day during adolescence had a 25% lower risk of breast cancer compared to their peers who consumed 0.5 servings of fruit per day. Another study published in September 2015 in the journal Annals of Oncology said that fruits and vegetables contain carotenoids and other antioxidants, and that consuming more fruits and vegetables can reduce the risk of lung cancer by 8 to 18 percent. In fact, there have been numerous studies that have confirmed that fruits can protect against cancer. A diet structured with fruits and vegetables can reduce cancer in several areas, especially in the digestive and respiratory systems. II. Why fruits can reduce the incidence of cancer People may be particularly curious as to why fruits can reduce the incidence of cancer. Some studies say that fruits mainly rely on antioxidants and dietary fiber to prevent cancer: antioxidants: antioxidants include familiar vitamins, such as vitamin C, which may have certain inhibitory effects on breast cancer and colorectal cancer; they also include flavonoid compounds, organic sulfides, etc. Food fiber: fruits are rich in food fiber, which can stimulate intestinal peristalsis and accelerate the excretion of toxic substances. And food fiber can also combine with some potential carcinogens, secondary bile acids and other harmful substances, thus reducing the absorption of these substances in the intestine. However, the anti-cancer mechanism of fruits is not very clear. There are some such nutritional supplements on the market, and the ingredients inside are taken out separately to sell …… Taking these supplements is not as good as eating fruits directly. There are many star fruits in the anti-cancer world, such as these: apple: rich in vitamin C, anthocyanin, dietary fiber, etc.; blueberry: rich in vitamin C, vitamin K, manganese and dietary fiber, etc.; cherry: rich in vitamin C, vitamin A, anthocyanin, potassium and dietary fiber, etc. These fruits can reduce the risk of colorectal cancer and have a role in defending against lung cancer, oropharyngeal cancer and laryngeal cancer. There is a common saying: golden apple in the morning, silver apple at noon and poisonous apple at night. In fact, this is a complete rumor. No matter when you eat apples, they will go through the same digestion process. Remember the following three points, you can eat fruit scientifically! 1.Choose a good time difference It is best to eat between Chinese food and lunch, or between lunch and dinner, so that it will not hold up …… 2, choose a good way It is best to choose fresh fruit in season. If the teeth can eat fruit directly, try not to beat into juice. Because a study shows that eating squeezed fruit juice can not reduce the incidence of cancer. 3. Diabetes eating fruit should be noted Sugar lovers should eat fruit only after blood sugar is stable and fasting blood sugar is controlled below 7.8 mmol/L. To choose fruits with lower sugar content, such as apples, oranges, pears and kiwis have lower sugar content; while bananas, lychees, red dates, grapes and sugar cane have higher sugar content. The last point, pay attention to control the amount of fruit. Generally choose about 200g (four or two) of low-sugar fruit, while reducing the corresponding 25g of staple food in order to ensure that the daily calorie remains unchanged.
