What are the dietary protections against colon cancer?

Colon cancer is the most common cancer in Western Europe and the United States, second only to lung cancer. Western diets are mainly meat and animal fat, which can easily stimulate the intestines to produce carcinogenic substances. Studies by scientists in Western countries have shown that if the diet is rich in fiber, the incidence of colorectal cancer will be greatly reduced. Some studies believe that the substances produced by the fermentation of cellulose in vegetables in the intestine can promote cell differentiation and prevent colon cancer. Other studies believe that fiber can protect intestinal cells and reduce the stimulation of bile on intestinal wall cells, thereby reducing the incidence of colon cancer. High-fiber foods contain not only fiber, but also many other healthy ingredients. Studies have shown that other ingredients in high-fiber foods can also effectively prevent cancer. Phytohemagglutinin in broad beans can promote the differentiation of intestinal wall cancer cells, prevent or even reverse the development of colon cancer. Oranges are rich in antioxidants, which can remove free radicals in the body and enhance the activity of the immune system, thereby improving the body's anti-cancer ability. Fiber can prevent constipation, promote metabolism, lower cholesterol, and reduce the occurrence of cholelithiasis. Fiber can also reduce the body's absorption of fat, which is of great benefit to patients with heart disease and hypertension. Other studies have found that fiber can reduce the body's need for insulin and is helpful in preventing and treating

Eat enough to prevent colon cancer

Why do high-fiber foods have the effect of preventing colorectal cancer? First, fiber cannot be digested in the intestines, which can stimulate the gastrointestinal tract to accelerate peristalsis, increase the volume of the gastrointestinal tract, and soften the stool, so it can speed up the excretion of feces. Secondly, fiber in the gastrointestinal tract can be reflected to the brain through nerves, giving the brain enough time to realize that the body is no longer hungry, thereby preventing overeating and reducing the burden on the gastrointestinal tract.

In addition, undigested fiber can also absorb carcinogens in food residues in the gastrointestinal tract, such as nitrosamines and polycyclic aromatic hydrocarbons, so that these carcinogens are excreted from the body with feces. In addition, fiber can reduce fat intake and prevent the body from becoming too obese, which is also a risk factor for colorectal cancer.

A study conducted by American researchers once concluded that high-fiber foods do not reduce the incidence of colorectal cancer. However, the American respondents did not meet the standard of consuming 35 grams of high-fiber foods per day. In contrast, the European survey covered 10 countries and more than 500,000 people, and the data calculation was more rigorous. The report clearly pointed out that consuming enough high-fiber foods every day can indeed reduce the incidence of colorectal cancer.

It is effective only if you take more than 35 grams a day

British nutritionists recommend that people should consume at least 35 grams of fiber every day to play a preventive and health-care role. According to rough calculations, a bowl of cereal contains 15 grams of fiber, a slice of whole-wheat bread contains 2 grams of fiber, a banana contains 3 grams of fiber, and an apple contains 3.5 grams of fiber. People can adjust their three meals according to their needs to ensure that they consume enough fiber.

The above is a brief introduction to colorectal cancer. For people who are related to the pathogenic factors of colorectal cancer, it is recommended to take preventive measures against colorectal cancer and receive specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about colorectal cancer, please consult our experts online or call for consultation.
