"Popular Science Nutrition" Intestinal Polyp: Have you eaten the right diet?

When people reach middle age, about 10-30% will develop intestinal polyps. Most intestinal polyps are asymptomatic and may never be found without colonoscopy. When abdominal pain, diarrhea or intestinal bleeding occur, it is lucky to be found during colonoscopy. Although it grows slowly, it is an important source of colorectal cancer, and it should be removed as much as possible once it is found.

Why are there intestinal polyps? It's not clear yet. Studies have shown that people who are overweight, obese, smoking and have a family history are at higher risk of developing polyps, and diet is also a factor that cannot be ignored. Improper diet will increase the risk of intestinal polyps, while proper food can prevent the occurrence of polyps, prevent development and reduce the chance of recurrence and canceration.

The effect of food on intestinal polyps is not clear. It doesn't appear immediately after eating a meal or a kind of food, and not everyone has a role. It is a process of habit and accumulation. Good food choices and eating habits are definitely beneficial to the prevention and treatment of intestinal polyps. The author collected the literature in recent years for readers.

1

Eat less red meat.

Adults need about 50g of protein every day, most of which can be obtained from plant food. However, people are omnivores. In recent years, commercially produced red meat, such as pork, beef and mutton, is nothing to eat. Various local flavors give red meat a unique taste. If there is a choice, most people will definitely choose delicious and oily red meat, which is one of the reasons for the increase of intestinal polyps and intestinal tumors in recent years. The culprit is heme and nitrite contained in red meat.

2

Eat less animal fat.

Overweight and obesity are the chief culprit of almost all diseases, and they are also risk factors for colon polyps and colon cancer. The fatter, the higher the risk. There are too many saturated fatty acids in red meat and white meat of animals, and excessive intake stimulates the production of too much bile, which is turned into valeric acid in the large intestine and has been proved to be a carcinogen. Saturated fat contains more arachidonic acid, which can promote the abnormal growth of intestinal epithelium into polyps and even cancer. These saturated fatty acids are collectively called bad fats. It is wise to reduce the intake and limit the total amount of fat to about 20-25 grams per day.

In contrast, foods rich in omega-3 unsaturated fatty acids have low arachidonic acid content, which is considered to have protective effects on colon polyps and cancer and is beneficial to human health, so it is called good fat. Omega-3 can only be ingested from food, such as salmon, sardines, mackerel and other fish, walnuts, wax gourd, tofu and other foods; Vegetable oils such as linseed oil, olive oil, rapeseed oil and peanut oil can be used for cooking.

Eat more foods rich in prebiotics.

Oligosaccharides are soluble fibers and elements beneficial to the growth of intestinal flora, so they are called prebiotics. After entering the intestine, they provide growth fuel for normal bacteria such as Bifidobacterium and lactic acid bacteria, produce acetic acid and lactic acid to acidify the intestine, inhibit the growth of harmful microorganisms, and provide a healthy environment for the growth of intestinal cells. The advantage is to reduce the possibility of intestinal cells transforming into polyps and canceration and prevent the growth of polyps. Bacteria living in the colon rely on the prebiotics we eat to make substances that maintain intestinal health. Scientists call these bacteria probiotics, which is a mutually beneficial phenomenon. Foods such as wheat, onion and garlic are rich in soluble fiber oligosaccharides, and bananas are considered as one of the most convenient sources of oligosaccharides.

four

Eat more foods rich in dietary fiber

Dietary fiber is not absorbed by human body, which promotes intestinal peristalsis after entering the large intestine, reduces the residence time of food and potential carcinogens in the intestine, and greatly shortens the contact time between carcinogens and intestinal wall. Dietary fiber is fermented by bacteria in the large intestine, which preserves the moisture in the stool, softens the stool, produces laxative effect and protects the intestinal ecology. Although clinical research is controversial, most scholars believe that it is beneficial to prevent intestinal polyps and intestinal cancer. More than 25g should be added every day. Foods rich in dietary fiber include figs, beans, barley, eggplant, pears and green leafy vegetables. The dietary fiber content of coarse grains is the highest, and the content of beans is the highest, while there is no dietary fiber in meat, eggs and milk. Chewy vegetables, wild vegetables and dark vegetables have high dietary fiber content, and the fiber content will not change after careful cutting.

five

Eat more foods rich in curcumin

Curcumin extracted from Curcuma longa, a traditional Chinese medicine, is a spice that yellows curry and food, and is one of the natural food additives allowed by the state. Medically, it has the functions of reducing blood fat, anti-inflammatory, anti-oxidation, anti-tumor and cholagogic. A study on familial polyposis found that after taking 480 mg curcumin and 20 mg quercetin every day for 6 months, the number of polyps decreased by 60% and the number of polyps decreased by half. There are many foods such as onion, mustard, ginger and curry, among which the content of curry is as high as 60%. It is beneficial to eat more onions and use mustard, ginger and curry as seasoning.

six

Eat more foods rich in quercetin.

Quercetin is a natural plant flavonoid with antitussive, expectorant, antioxidant and antitumor effects. Clinical research shows that it has the potential to prevent and control the formation of intestinal polyps. Apple, onion, wine and green tea are the best natural sources of bioflavonoid quercetin. Onion is one of the best natural sources of quercetin in vegetables, and it is also the least likely to contain pesticides and other potentially carcinogenic chemicals.

seven

Eat more foods rich in radish sulfur.

Nutritional superstars broccoli and cabbage are classified as cruciferous vegetables, which are rich in glucosinolates and converted into isothiocyanates and sulforaphane after chewing and digestion. Studies have found that sulforaphane can protect animal intestines, slow down the growth of polyps and induce the self-destruction of harmful cells, which is called apoptosis. If you want to find a powerful food to reduce the risk of intestinal polyps, broccoli, cauliflower, carrots and white radish are the best natural sources of radish sulfur. Studies have found that sulforaphane will be destroyed up to 90% after cooking, so you should try to eat it raw or slightly cooked to maximize its efficacy in preventing and treating intestinal polyps.

eight

Eat more foods rich in folic acid.

Folic acid, also known as vitamin B9, is an important essential vitamin to maintain life. 14 a study by nurses and health experts shows that taking more than 400 micrograms of folic acid every day has a protective effect on the formation of polyps, and the probability of developing colon cancer is small. Foods rich in folic acid can be obtained from cereals such as rice, wheat and corn. , but also from beans, lentils, asparagus, spinach, lettuce, avocado, broccoli, mango, oranges and other foods containing more folic acid.

nine

Eat more garlic and ginger.

Allicin is a compound with the unique taste of garlic. Studies have shown that allicin can effectively reduce the risk of colon cancer and colon polyps. Before eating or cooking, let the chopped garlic contact the air for 10 minute to release more allicin. Gingerol is the main active compound of ginger, which has been proved to reduce the size and number of tumors in experimental animals.

10

Eat more colorful vegetables.

Colored vegetables are rich in vitamins and minerals, and contain more antioxidant and antitumor plant active ingredients. Green vegetables such as spinach, green pepper and broccoli contain more chlorophyll and lutein; Red vegetables such as tomatoes, peppers and red bell peppers contain lycopene and capsanthin; Orange vegetables such as carrots, pumpkins and yellow peppers contain β-carotene, which can be converted into vitamin A in human body. Purple vegetables such as purple cabbage, beet and purple potato contain anthocyanin and betanin. Studies have found that lycopene and capsaicin may help reduce the risk of intestinal polyps and colon cancer. A study on 62 cases of intestinal polyps after resection found that taking 800 mg of n- acetylcysteine with anticancer properties of red pepper every day can reduce the recurrence rate of polyps. The deep red soup made of beet and carrot is the best collocation to prevent colon polyps.

Eat more foods rich in calcium, magnesium and vitamin D.

The strong bone function of calcium is well known, and calcium can also regulate the growth of human cells. Animal studies have found that calcium deficiency leads to the overgrowth of colon cells; Clinical studies have found that calcium supplementation 1200mg per day can reduce the risk of intestinal proliferative polyp by 14-35%, but it can increase the risk of serrated polyps. It is generally believed that calcium intake from diet is beneficial and safe to prevent intestinal polyps. Adults need to consume 1000mg every day, and a bottle of milk can provide enough calcium. People who don't drink milk and yogurt can supplement calcium through shellfish, seafood and green leafy vegetables. Calcium in green leafy vegetables will be affected by oxalic acid, which is not as easily absorbed by human body as calcium in milk. Arugula contains a lot of calcium, and oxalate is less absorbed. Foods rich in calcium should be matched with foods rich in magnesium and vitamin D to ensure the absorption of calcium.

A study found that taking 645 international units of vitamin D every day can reduce the risk of dangerous colon polyps by one third. Vitamin D can control the proliferation rate of intestinal polyp cells and promote the absorption of calcium. The best sources of vitamin D include liver, fish and vitamin D fortified dairy products, and more sun exposure can also produce vitamin D. ..

The absorption of calcium needs magnesium. It is found that the perfect ratio of these two minerals is 2: 1, which can better prevent the growth of polyps. Mild magnesium deficiency is common in people. Green leafy vegetables are natural sources of magnesium, but they will lose a lot of magnesium in the process of greenhouse growth and food processing. Spinach is rich in magnesium, which is one of the most valuable vegetables for anyone who cares about colon polyps. It is very effective in cleaning and protecting the intestines.

12

Eat more foods rich in vitamin e.

Vitamin E plays an important role in human antioxidant system, which has been proved to prevent cancer, and it has been reported that it is beneficial to prevent intestinal polyps. Wheat germ Wheat germ is one of the most concentrated natural sources of vitamin E. Lettuce, tomato, carrot, green leafy vegetables, egg yolk, nuts, meat and dairy products are all rich in vitamin E, so the processing temperature should not be too high to avoid being destroyed.

13

Eat more foods rich in selenium.

Population studies show that people with high selenium intake have a lower risk of death from colon polyps and colorectal cancer. Seafood shrimp, edible fungi, broccoli, purple potato, black bean, black sesame and garlic all contain more natural selenium.

conclusion

Food has a certain preventive and therapeutic effect on intestinal polyps. Choosing the above foods is definitely beneficial. As long as you develop good eating habits, it will gradually show its preventive and therapeutic effects. Eat less animal meat, eat more plants and vegetables, eat less meat and eat more vegetarian food. The more kinds of food you choose, the simpler the processing process.

Broccoli, the king of preventing intestinal polyps in food.
