High-fat diet can easily induce colorectal cancer

Colorectal cancer is the most common digestive tract tumor, and has a high mortality rate among various malignant tumors. It is caused by one's own genetic factors and external influences. Among them, unscientific eating habits in daily life are also one of the causes of colorectal cancer . In particular, long-term consumption of high-fat foods is one of the main causes of colorectal cancer.

A high-fat diet, especially one containing saturated fatty acids, can promote the production of cholesterol metabolites and secondary bile acids, which can cause cancer. Insufficient dietary fiber can increase the chance of carcinogens coming into contact with the colon mucosa.

The so-called Western diet of high fat, high protein and low fiber is believed to be related to the occurrence of colorectal cancer. The most typical dietary structure of modern people is the "three highs and one low" phenomenon, that is, high calories, high fat, high protein and low fiber. High-fat and high-protein foods can increase the amount of methylcholanthracene in feces, which can lead to increased bile acid secretion and be decomposed into unsaturated polyhydrocarbons by anaerobic bacteria in the intestines. Both of these substances are carcinogens. At the same time, the reduction of fiber in food slows down the speed of feces passing through the intestines, increasing the contact time between these carcinogens and the intestinal conjunctiva, resulting in an increase in the chance of canceration, which plays a role in fueling the occurrence of colorectal cancer.

The causes of colorectal cancer are mostly closely related to environmental factors, especially dietary factors. With the increasing intake of refined foods, animal fats and proteins, the intake of vegetable, fruit and other plant foods has been relatively reduced. In addition, irregular diet, reduced exercise, smoking, drinking and other bad living habits lead to the body's inability to absorb enough dietary fiber, and toxic substances accumulate in the large intestine for a long time, thus leading to the occurrence of colorectal cancer.

To prevent colorectal cancer, we should not only eat less high-fat foods, but also develop good eating habits in daily life. I hope that readers can effectively apply disease knowledge in daily life and actively and effectively prevent colorectal cancer.
