Dietary fiber can prevent colon cancer. What can you eat to prevent colon cancer?

Colon cancer is a common malignant tumor that may not have any symptoms in the early stage. In the middle and late stages, patients often experience symptoms such as abdominal distension, indigestion, abdominal pain, mucus in stool, blood in stool, and systemic symptoms such as anemia, low fever, weight loss, and fatigue. Studies have shown that the occurrence of colon cancer is mainly related to a high-fat and low-fiber diet. Appropriate intake of dietary fiber in life can prevent colon cancer.

Why can dietary fiber prevent colon cancer?

The concept of dietary fiber was proposed in the 1970s. Some scientists believe that the occurrence of many human diseases is related to insufficient dietary fiber intake. Dietary fiber can be divided into two categories, namely water-soluble dietary fiber and water-insoluble dietary fiber. Representative foods of water-soluble dietary fiber include vegetables, fruits, barley, oats, citrus, carrots, whole grains or beans, etc., which have the effect of stabilizing blood sugar and controlling cholesterol.

Representative foods of insoluble dietary fiber include grains, beans, root vegetables, fruit peels, corn, celery, broccoli, etc. Insoluble dietary fiber can absorb water, help form stools, stimulate gastrointestinal motility, strengthen defecation, and prevent constipation.

Scientists believe that dietary fiber can effectively prevent colorectal cancer because dietary fiber has strong water absorption. It can absorb harmful substances in our intestines like a sponge, increase the volume of feces, and make feces shaped and easier to excrete. This can shorten the residence time of feces in the intestines, accelerate the excretion of carcinogens, and reduce the contact between carcinogens and the intestinal wall. It reduces the concentration of carcinogens in the intestines, thereby reducing the risk of colon cancer.

Therefore, to prevent colon cancer in life, it is recommended to eat more dietary fiber. Specific foods include vegetables, fruits, oats, corn, whole grains, beans and other foods. At the same time, it is also necessary to ensure a diversified diet, and take in fish, meat, milk and other foods appropriately to maintain a balanced nutrition. Eat less pickled, smoked, fried, and grilled foods, do not eat moldy foods, do not eat too much fat, do not eat overly hot and overheated foods, do not drink alcohol, and do not smoke. It is also necessary to strengthen physical exercise, maintain a standard weight, and maintain a good mood.
