To prevent colon cancer, stay away from high-fat diet

The main physiological function of the colon is to absorb water and store food residues to form feces. The glands of the colon mucosa can secrete thick mucus, which is alkaline and can neutralize the fermentation products of feces. When the colon is suffering from cancer, the physiological function is damaged, and the defecation function and the whole body condition are affected, such as diarrhea, difficulty in defecation, and weight loss. If you still don't pay attention to your diet and eat some indigestible foods and cancer-promoting foods, it will aggravate the progression of colon cancer and cause systemic failure. Patients with colon cancer must pay attention to their daily diet.

Studies have shown that high-fat diets promote the occurrence of intestinal tumors, especially polyunsaturated fatty acids, which can reduce blood lipids but promote cancer. Cholesterol itself is not carcinogenic, but it reacts with cholelithic acid and has a carcinogenic effect, indicating that cholelithic acid is a carcinogenic factor. Therefore, patients with colon cancer should not eat too much fat, the total amount of fat should account for less than 30% of the total energy, and the proportion of animal and vegetable oils should be appropriate. In other words, in a day's diet, including the amount of fat in the food itself and the oil used in cooking, the daily fat should be less than 50 grams. Some friends are afraid of coronary heart disease and control animal fat very strictly. They often eat vegetable oil as the main food, or even do not eat animal oil, which will cause excessive peroxides in the body. Because the carbon chain in vegetable oil is unstable and easy to oxidize, if you eat some animal fat appropriately, the carbon chain will be stable and not easy to oxidize, and the formation of free radicals in the body will be reduced. Therefore, you must eat scientifically and pay attention to the reasonable ratio of oils and fats. It is recommended that the ratio of saturated fatty acids to polyunsaturated fatty acids and monounsaturated fatty acids is 1:1:1.

In the diet, you should pay attention to eating more vegetables rich in dietary fiber, such as celery, leeks, cabbage, radish and other green leafy vegetables. Vegetables rich in dietary fiber can stimulate intestinal peristalsis, increase the frequency of bowel movements, and remove carcinogenic and toxic substances from the feces. If colon cancer bulges into the intestinal cavity and the intestinal cavity becomes narrow, you should control the intake of dietary fiber, because excessive intake of dietary fiber can cause intestinal obstruction. At this time, you should give easily digestible, soft semi-liquid foods, such as millet porridge, thick lotus root soup, rice soup, porridge, cornmeal porridge, egg custard, tofu brain, etc. These foods can reduce the stimulation to the intestines, pass through the intestinal cavity more smoothly, and prevent the occurrence of intestinal obstruction.
