Colon cancer is a common malignant tumor. It can be without symptoms in the early stage. Patients in the middle and advanced stages often have the symptoms of abdominal distension, indigestion, abdominal pain, mucus, and blood in the stool, and have 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. Proper intake of dietary fiber in life has the effect of preventing 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, which are water-soluble dietary fiber and non-water-soluble dietary fiber. The representative foods of water-soluble dietary fiber are vegetables, fruits, barley, oats, citrus, carrots, whole grains or beans, etc., which are stable. Blood sugar and cholesterol control.
The representative foods of non-water-soluble dietary fiber are cereals, beans, root vegetables, peels, corn, celery, broccoli, etc. Non-water-soluble dietary fiber can absorb water, can help stool formation, stimulate gastrointestinal peristalsis, and strengthen defecation. Play a role in preventing constipation.
The reason why scientists believe that dietary fiber can effectively prevent colorectal cancer is because dietary fiber has strong water absorption. It can absorb harmful substances in our intestines like sponges. It can increase the volume of feces and make the feces formed to facilitate discharge. Shorten the residence time of feces in the intestine, accelerate the excretion of carcinogens, reduce the contact between carcinogens and the intestinal wall, reduce the concentration of carcinogens in the intestine, and reduce the risk of colon cancer.
