Why is a bad diet harmful to intestinal health? See what gastroenterologists say.
Take meat as an example. Why does meat destroy intestinal health? This is because meat has no dietary fiber and contains more fat and cholesterol. If you eat a lot of meat or processed meat, but seldom eat carbohydrates such as grains, beans and vegetables, the amount of defecation will decrease. In order to transport feces to the rectum, the large intestine needs to creep very hard, which leads to the thickening of most muscle layers in the intestinal wall.
In addition, due to the intake of a large amount of fat, not only the superficial subcutaneous fat thickens, but also the periintestinal fat layer thickens, the inner diameter becomes thinner, and the wrinkles on the intestinal wall increase, which is easy to cause spasm pain with a little stimulation.
Moreover, eating like this for a long time will obviously increase the intestinal pressure, which will not only cause digestive dysfunction, induce constipation and other problems, but also cause sudden rupture and perforation of the intestine. For a long time, intestinal epithelial cells (cells that are very prone to malignant transformation) will mutate under the cumulative stimulation of harmful substances, which will increase the chances of suffering from colorectal polyps and colorectal cancer.
As for the possible increase of cholesterol in the blood, it may lead to hypertension and arteriosclerosis, which may further lead to heart disease, kidney disease, myocardial infarction, stroke and other diseases, not to mention. Therefore, people who mainly eat meat can't see an unhealthy state except for the potbellied appearance of some people, but their inner intestines are suffering and miserable.
Therefore, through the above analysis, it is clear at a glance that the diet that is easy to harm intestinal health:
1, foods high in fat, cholesterol and trans fatty acids.
All kinds of fried foods with high oil content, such as fried food, fat, animal offal, cream products, etc. Various foods with high trans fatty acids, such as instant noodles, shortcakes, puffs, egg yolk pie, buttered bread, milk tea, ice cream, etc.
2. Barbecue food
High-temperature charcoal fire heating makes meat produce benzopyrene, nitrosamines and other substances harmful to the intestine. Long-term consumption will increase the risk of digestive tract tumors. It's not like you can't eat it, control? Quantity? This is very important. Not for a long time, but occasionally.
3. Spicy food
Satisfy your mouth, but work hard for your stomach. Spicy and irritating food, not only peppers, but also curries and peppers. Can induce gastroenteritis and even malignant lesions. For spicy food, everyone may be different. If you can't tolerate it well, or you don't have the habit of eating spicy food, you'd better eat less.
4. Alcohol, especially the inferior liquor with 40 degrees, is harmful to the intestines. There are also strong coffee, strong tea and so on. And long-term drinking will also damage the intestines.
How to eat the healthiest?
Share a nutritionist's opinion that we humans have 10 pairs of molars, 4 pairs of incisors and 2 pairs of canine teeth, with a ratio of 5:2: 1. Molar teeth are used to eat food and beans, front teeth are used to eat fruits and vegetables, and canine teeth are used to eat meat, and each has its own duties. In terms of diet, dividing the diet into plant food and animal food, that is, 7: 1, is the best scheme to maintain a balanced diet.
