What are the disadvantages of overeating?

1, stomach trouble. The direct harm caused by overeating is increased gastrointestinal burden and indigestion. In addition, human gastric mucosal epithelial cells have a short life span and need to be repaired every 2-3 days. If the last meal has not been digested, the stomach will be full at the next meal, and the stomach will always be full, so the gastric mucosa will not be easily repaired. The stomach will secrete a lot of gastric juice, destroy the gastric mucosal barrier, produce gastric inflammation, and have indigestion symptoms. In the long run, diseases such as gastric ulcer may occur.

2. Intestinal diseases. Some scientists have found that fat blocking in the intestine can cause intestinal obstruction, melena and bloody stool.

3. Obesity. The high-fat and high-protein foods that modern people often eat are more difficult to digest. Too many "nutrients" accumulate in the body, and the consequence is obesity and a series of diseases of wealth. Hong Zhaoguang, chief health expert of the Ministry of Health, said: A large number of scientific studies have confirmed that obesity will bring cardiovascular diseases, hypertension, diabetes, fatty liver, arteriosclerosis and cholecystitis. And the resulting complications may reach hundreds, which is very terrible.

4, kidney disease. Eating too much will harm people's urinary system, because too much non-protein nitrogen will be discharged from the kidneys, which will inevitably increase the burden on the kidneys.

5. Acute pancreatitis. Eating too much and drinking too much at dinner can easily induce acute pancreatitis.

6. Fatigue. After people are full, the blood goes to the gastrointestinal system to "work", which makes people feel tired and sleepy for a long time.

7. Affect the brain and accelerate aging. Eating too much will lead to brain dullness and accelerate brain aging. In particular, overeating at dinner will affect brain energy metabolism, which in turn will affect brain function. [1] After years of experiments and observations on mice, Mr. Masaki Guada, a lecturer in the Department of Microbiology, Faculty of Medicine, Tokai University, Japan, came to a convincing conclusion: mice whose food is controlled at eight live longer than those whose food is too full. [2]

8. cancer Eating too much will reduce the activity of factors that inhibit cell canceration and increase the risk of cancer.

9. osteoporosis. Long-term satiety can easily lead to excessive decalcification of bones, and the probability of osteoporosis will be greatly improved.

10, neurasthenia. If you eat too much at dinner, the swollen gastrointestinal tract will oppress the surrounding organs, so that the excited "electric waves" will spread to other parts of the cerebral cortex and induce neurasthenia.

Alzheimer's disease 1 1. Some scholars have confirmed that satiety can induce a substance called fibroblast growth factor in the human brain. After a full meal, its content in the brain is tens of thousands of times higher than that before eating, and its increase is directly proportional to the amount of food eaten. It has been proved to be the culprit of cerebral arteriosclerosis. Cerebral arteriosclerosis is closely related to Alzheimer's disease. Scholars have also found that about 20% of Alzheimer's patients are full-fledged "gourmets" when they are young.

In a word, satiety is very harmful. Health education experts said: "In ancient times, in addition to digestion, the stomach also played a reserve function, so it was no problem to be hungry for three days;" Nowadays, people eat well every day. If a person's stomach can hold 1 kg of food every day, then only half a day is enough. Otherwise, it will only overload the body and cause a series of health problems. "In order to make us healthier and live longer, don't eat too much.
