Three bad eating habits that may cause colon cancer

Colon cancer is a common malignant tumor of the digestive tract. The specific cause of the disease is not yet fully understood. Current research shows that bad eating habits are an important predisposing factor for colon cancer. The main bad habits that induce colon cancer are:

1. Low dietary fiber diet

Dietary fiber can resist degradation by digestive enzymes in the body. It is mainly divided into non-polysaccharides and exists in vegetables, fruits, grains, etc. Fiber increases bowel movements and dilutes carcinogens in the colon; fiber can absorb bile salts (promoters of colorectal cancer); fiber is fermented by bacteria to produce broken-chain fatty acids and lower pH, which is not conducive to the growth of cancer cells. In other words, a high-fiber diet can prevent colon cancer.

2. High-fat, high-protein diet

A high-fat diet is a risk factor for colorectal cancer. A survey shows that people who eat a high-fat diet have a colorectal cancer incidence rate that is twice as high as those who eat a low-fat diet. Protein itself is not carcinogenic, but there is evidence that some potential carcinogens come from dietary protein.

3. Trace elements and vitamins

Calcium and selenium are two trace elements that have been studied more in colorectal cancer. Calcium ions combine with lipids to form insoluble calcium soaps, inhibit fatty acids and bile acids, and protect the intestinal epithelium. Epidemiology also suggests that calcium has a protective effect on preventing colorectal cancer. Selenium can inhibit cell proliferation and inhibit tumor promotion.
