How to prevent colorectal cancer

Cancer, I believe many people shudder when hearing this word. Yes, cancer is an incurable disease, such as colorectal cancer. Some people believe that carcinogens in nitrosamine compounds are an important cause of human esophageal cancer and gastric cancer, and are also one of the causes of colorectal cancer. Although the reason is not very clear, a large amount of research data shows that the occurrence of colorectal cancer is closely related to eating habits and lifestyle. So, how can we prevent it?

1. Primary prevention

(1) Adjusting dietary habits and lifestyle: Dietary habits and lifestyle are closely related to the occurrence of colorectal cancer due to high protein, high fat, lack of vitamin A and low fiber. Therefore, in terms of dietary habits and lifestyle, it is recommended to increase the proportion of crude carbohydrates from high-fiber fruits such as bananas, green leafy vegetables (cabbage, greens, potatoes, sweet potatoes, etc.), and cereals (such as corn), reduce the proportion of fat and animal protein (such as beef) and refined carbohydrates, increase stool volume and intestinal excretion rate. In this way, on the one hand, the concentration of neutral sterols and bile acids in the intestine can be reduced, which also reduces the carcinogens or co-carcinogens degraded by intestinal bacteria. On the other hand, due to the increase in stool volume, the excretion rate is accelerated, so that the above-mentioned carcinogens or co-carcinogens are in contact with the colon mucosa for a shorter time, which can reduce the incidence of colorectal cancer.

①Energy intake Energy intake is related to the occurrence of colorectal cancer. Most studies have shown that total energy intake is related to the risk of colorectal cancer, regardless of whether the energy intake is protein, fat or carbohydrates. Reducing energy intake may reduce the incidence of colorectal cancer.

②Fat and red meat The occurrence of colorectal cancer is closely related to animal fat and meat. Studies have shown that women with a high-fat diet have a 32% higher risk of colorectal cancer than women with a low-fat diet. The intake of red meat is a strong risk factor for colorectal cancer. Reducing the fat content in food, especially eating less brown meat after frying or grilling, can contribute to the occurrence of colorectal cancer.

③Fruits, vegetables and dietary fiber cellulose can increase stool volume, dilute carcinogens in the colon, and absorb bile salts, thereby reducing the occurrence of colorectal cancer. Therefore, in daily diet, you should try to consume more vegetables, fruits, and cellulose, eat a reasonable diet, and reduce the occurrence of colorectal cancer.

In short, a healthy lifestyle can help prevent the occurrence of colorectal cancer. People with abdominal obesity are more likely to be at risk of colorectal cancer. Physical activity can affect large intestine peristalsis and facilitate the excretion of feces, which can prevent colorectal cancer. Smoking and drinking can induce the occurrence of colorectal cancer.
