What to eat to prevent colon cancer

When treating rectal cancer, we often encounter various obstacles. For example, some people need to make money to support their families and do not have much money to treat rectal cancer, so they are caught in a dilemma. In fact, if we pay attention to our diet before rectal cancer occurs, it is equivalent to saving the cost of treating rectal cancer. What can we eat to prevent colon cancer?

The more starchy foods you eat, the lower the incidence of colorectal cancer. Many studies have found that the more starchy foods you eat, the lower the incidence of colon and rectal cancer. For example, the incidence of colon cancer in Australians, who eat meat as their staple food, is four times that of Chinese people, who eat starchy foods as their staple food.
Starchy foods can prevent colorectal cancer. Starchy foods mainly inhibit colorectal cancer in two ways: first, when starch enters the intestine, a series of reactions help increase feces, promote colon excretion, and accelerate the excretion of carcinogenic metabolites from the body; second, starch will produce a large amount of butyrate through the action of fermentation enzymes in the intestine. Experiments have shown that butyrate is an effective cancer cell growth inhibitor. It can directly inhibit the reproduction of colon bacteria and prevent the production of potentially carcinogenic cells in the inner wall of the colon.
How should we choose starchy foods in our daily life? The so-called starchy foods mainly refer to staple foods rich in carbohydrates, such as rice, corn, wheat, etc., and root vegetables such as potatoes, yams, potatoes, etc. In addition, they also include various beans and bananas and other fruits that are rich in starch.
