Is 'meat' an 'accelerator' for polyps? If you don’t want polyps to become cancerous, stick to these 4 things or it may be effective

Big Brother Tian likes fitness very much. Every day after get off work, he has to practice in the gym for a while. In order to get in shape, Brother Tian has put a lot of effort into his diet in the past year. The coach suggested that he should eat a lot of meat at every meal, so Brother Tian basically eats meat every day, plus a little protein powder, and hardly eats it. green vegetables.

But Big Brother Tian found that his bowel habits had changed. The coach said that this was a normal performance caused by the ratio of meat to vegetables, and Big Brother Tian didn't care too much.

But from the last two months, Big Brother Tian found that he also had blood in the stool , and later he was often accompanied by abdominal pain, constipation and diarrhea alternately.

Worrying about gastroenteritis, Big Brother Tian planned to go to the hospital for a gastroenteroscopy, but after an examination, he found that the colon was full of large and small polyps! The doctor analyzed that it may be that Brother Tian often eats high-protein foods and eats less vegetables and fruits, thus stimulating the growth of intestinal polyps.

1. Is "meat" the "catalyst" of polyps?

Eating red meat is closely related to polyps and rectal cancer, so how does meat cause polyps?

According to Dr. Li Jingnan, Department of Gastroenterology, Peking Union Medical College Hospital, after eating meat, it is thoroughly chewed in the mouth, and then enters the stomach, becomes a paste under the action of the stomach, absorbs part of the fat, and then enters the small intestine.

Because meat contains saturated fatty acids, the small intestine makes the gallbladder secrete bile for digestion, and bile acids and cholesterol enter the large intestine together with the food, because the large intestine has a large number of bacterial flora, which combine with bile acids and cholesterol. May produce carcinogens and irritate the intestines. Under long-term stimulation, polyps may develop, and if polyps continue to develop, they may increase the chance of cancer.

Of course, in addition to eating meat, the occurrence of polyps may also be related to the following factors:

Long-term unbalanced diet, long-term consumption of high-fat, high-protein, and low-fiber diets will increase the burden of intestinal digestion due to the high fat content in the diet, thereby increasing the incidence of polyps;

In addition, it may also be a genetic factor. Among patients with colorectal cancer, about 10%-27% of the patient's family has a member who has suffered from the cancer. If you have familial adenomatous polyps, other people in the family are more likely to have colorectal polyps.

Intestinal inflammatory stimulation is common in patients with chronic ulcerative colitis, intestinal schistosomiasis, intestinal tuberculosis, etc. Because the intestinal tract is in a state of inflammation for a long time, it is also more likely to cause inflammatory polyps.

2. These 3 kinds of meat on the body may have the risk of cancer

Many people have found polyps in physical examinations. Are polyps dangerous and how far is it from cancer?

Polyps are actually raised lumps on the surface of the mucous membrane, not only the intestines, but wherever there are mucous membranes, such as the cervix, gallbladder, etc., polyps can appear, but not every polyp becomes cancerous.

The vast majority of polyps are benign and do not pose a threat to life. Even if they become cancerous, they need to go through a relatively long process. Therefore, through regular inspection, early detection of polyps, and timely treatment, is an effective way to prevent the occurrence of cancer.

When it is found that these three types of polyps in the body have a higher risk of cancer, it is necessary to pay attention:

1. Intestinal polyps

Intestinal polyps are "time bombs" in the intestine, especially the long-villiform polyps have a cancer risk of nearly 30%, and multiple polyps are often more dangerous.

For single polyps found in the intestine, small in size and smooth surface, they are generally benign and can be temporarily observed or surgically removed to reduce the risk of canceration, while for polyps that are large (greater than 2 cm), multiple, and irregular in shape Yes, the malignant transformation may be larger, and excision is recommended.

2. Stomach polyps

Gastric polyps generally do not cause discomfort, but some patients also occur at the gastric pylorus, which may cause nausea and vomiting.

Gastric polyps are classified as inflammatory or hyperplastic polyps or adenomatous polyps, with the latter having a higher risk of becoming cancerous. For single, less than 1 cm in diameter polyps, can be temporarily observed. If the polyp volume is greater than 2 cm and the number is large, it is multiple polyps, and it is recommended to deal with it in time.

3. Gallbladder polyps

In the case of the gallbladder, gallbladder polyps may indicate inflammation or stones not detected by ultrasound, and the larger the polyp, the higher the risk of cancer. Generally, if it is less than 1CM, it can be reviewed regularly. For polyps with large diameter or small diameter, but the short-term growth rate is too fast, timely treatment is also recommended.

3. If you don’t want polyps to recur, eat 4 more foods

The occurrence of polyps is an accumulation process, and good food choices and eating habits are intentional for the prevention and treatment of polyps. So what adjustments should you pay attention to in your daily diet?

· Rich in dietary fiber

These foods include beans, wheat, eggplant, green leafy vegetables, etc. Dietary fiber cannot be absorbed by the human body, which can promote intestinal peristalsis, reduce the time that food and potential carcinogens stay in the intestine, and reduce the chance of the large intestine being exposed to harmful substances.

Foods rich in folic acid

Folic acid, or vitamin B9, is an essential vitamin for sustaining life. Studies have found that a daily intake of 400 micrograms of folic acid has a good effect on preventing polyps. Folic acid can be obtained in foods such as rice, wheat, corn, beans, spinach, lettuce, oranges, mangoes, etc.

· Rich in sulforaphane

Sulforaphane is most commonly found in cruciferous vegetables, such as radishes, broccoli, and cabbage. Studies have found that sulforaphane can protect the intestines of animals, slow down the occurrence of polyps, and induce the self-destruction of harmful cells, helping to reduce the production of harmful substances in intestinal polyps.

· Colorful vegetables

Vegetables with rich colors are not only rich in minerals, but also contain more antioxidant and anti-tumor plant active ingredients. Regular consumption can also help alleviate the risk of intestinal lesions.

Polyps are not cancer, but when polyps are found, they cannot be ignored. You must follow the doctor's orders, review them regularly, or deal with those that need to be removed to cut off the possibility of further development.
