But to tell the truth, it's hard to say clearly, the causes of cancer are too complicated, and the study of etiology is too time-consuming and labor-intensive, so it's hard to draw a clear conclusion … But at present, studies have proved that eating more fruits can prevent intestinal cancer!
As we all know, the basic foods we eat can be divided into five categories, namely, sweet potatoes, fruits and vegetables, animal foods, soybean nuts and oils, and there will be problems in eating more and less of each category.
Global disease burden research shows that unreasonable diet is the most important factor for the occurrence and death of diseases in China, while in 20 17, the main reason for the death of 3 10/00000 people in China was unreasonable diet, while the per capita fruit intake of Chinese residents was insufficient, as follows:
Long-term balanced diet can reduce the risk of chronic diseases. In view of the unreasonable long-term diet and unbalanced nutrition, China Nutrition Society organized the latest dietary guide for China residents (202 1), which provided a summary of the evaluation of different kinds of food intake and health. Details can be found in:
From the above picture, you can see that increasing fruit intake in the red areas can reduce the risk of digestive system tumors such as colorectal cancer, and the relevant literature evidence is listed later, so eating more fruits can effectively prevent colorectal cancer!
Of course, in addition to eating more fruits and having a balanced diet, the Dietary Guide for China Residents (202 1) also emphasizes "balanced nutrition" and "diversified food", and also has clear suggestions on the intake of eggs, viscera and fats, as follows:
1, eggs: it is recommended to eat 40 grams and 50 grams per day (about 1 egg), and eat eggs without discarding the yolk;
2, animal viscera: rich in fat-soluble vitamins and some trace elements, it is recommended to eat 2 times and 3 times a month, each time about 25 grams (half two);
3, fat: especially animal fat (animal oil, fat) intake, it is recommended to use vegetable oil for cooking every day, the intake is 25 grams and 30 grams per person (about half two).
In addition to the above, the guide also suggests eating less fat, smoking and curing meat products; Control the intake of added sugar and oil; Do not drink or drink less sugary drinks; Control salt intake.
Of course, the Dietary Guidelines for China Residents (202 1) guides most people, and everyone has different eating habits and physical conditions. For people with certain diseases (such as arteriosclerosis and hypercholesterolemia), the diet needs to be personalized.
In short, as long as you are not picky about food, eat vegetables, fruits, whole grains, fats, beans, nuts, dairy products, fish, etc. in a balanced way, and insist on daily exercise, you can effectively prevent intestinal cancer. At the same time, you should also do a regular physical examination. If you have defecation or abnormal intestinal discomfort, you should see a doctor in time.
