People who regularly consume olive oil have a significantly lower chance of developing colorectal cancer, while people who eat more meat and less vegetables, not surprisingly, have the highest chance of developing colorectal cancer. People living in the Mediterranean region have a significant preventive effect on colorectal cancer because of the high amount of olive oil in their food. The researchers conducted a total of 28 dietary surveys in different regions of the world before reaching this conclusion, and there are no conclusive studies on the cause, but they speculate that it is related to the metabolism of certain enzymes in the intestine, which are closely related to colorectal cancer. Experts suggest three requirements for the prevention of colorectal cancer: (1) rationalize the diet, eat more fruits, fresh vegetables and other foods rich in carbohydrates and coarse fibers, and reduce the intake of high-fat and high-protein foods. (2) Actively treat colorectal diseases such as ulcerative colitis, intestinal adenoma, etc. (3) If there are high-risk factors for colorectal cancer, such as familial colon cancer or polyposis, familial polyposis, ulcerative colitis, you should go to the hospital for consultation or examination regularly in order to keep track of your health condition.
