Modern nutrition research has found that after eating too much, the substance called' fibroblast growth factor' in the brain will increase significantly. If you are full for a long time, it will inevitably lead to cerebral arteriosclerosis, premature aging of the brain and mental retardation.
Cause of injury:
First, it causes stomach problems.
People's digestive system needs regular rest to keep normal work. If you are full, the food of the last meal has not been digested, and the food of the next meal fills your stomach, the digestive system will not get the rest it deserves.
Human gastric mucosal epithelial cells have a short life span and need to be repaired every 2-3 days. Eating midnight snack outside three meals a day often hinders the repair of gastric mucosa. Because food stays in the stomach for a long time, it forces the stomach to secrete a lot of gastric juice, destroys the gastric mucosa, and is prone to gastric erosion and gastric ulcer, thus inducing gastric cancer.
The second is abnormal development.
Overnutrition will also increase the burden and abnormal development of various organs in the body. Cardiovascular and cerebrovascular diseases, diabetes, fatty liver, obesity and other "rich diseases" are all caused by greed. In addition, the amount of parathyroid hormone in the body is directly proportional to the usual diet. Long-term satiety will increase parathyroid hormone in human body, which will easily lead to excessive decalcification of bones and osteoporosis. From people who are often full when they are young to old age, due to the obvious increase of parathyroid hormone content in the body, it is difficult to settle in the bones even if they take in more calcium, so the probability of osteoporosis will increase obviously.
Step 2 despise breakfast
Skipping breakfast makes people's blood sugar lower than the normal supply, which is insufficient for the nutrition supply of the brain and harmful to the brain for a long time. In addition, the quality of breakfast is also closely related to intellectual development. According to research, children who eat high-protein breakfast in class generally have a relatively long thinking time, while vegetarian children's mood and energy decline relatively quickly. Excessive sweets: Children with excessive sweets tend to have lower IQs.
As we all know, physical exercise can enhance physical fitness, and nutrition is the material basis of physical fitness. Therefore, sports nutrition must be balanced. In a day, getting up early to exercise pays the most energy. From the physiological needs, breakfast is the most important thing in a day. But many people ignore the function of breakfast. Breakfast is very simple, and some even go to work without breakfast. A person has not eaten for at least 12 hours from dinner on the first day to breakfast on the second day, and his stomach is empty. Breakfast determines the sugar level in the blood. If you eat breakfast and work or study at 10 in the morning, your blood sugar will be low, which will seriously affect the functional activities of the five permanent members of the brain. Yes People will feel flustered, dizzy, dizzy and even faint. So, not only eat breakfast, but also eat well. Foreign nutritionists disapprove of eating starchy food for breakfast. They think there should be enough protein and fat to achieve a balance between import and export. Only in this way can health be guaranteed.
3. Long-term smoking
German medical scientists' research shows that smoking all the year round causes brain tissue to shrink to varying degrees, and it is easy to get Alzheimer's disease. Because long-term smoking can cause cerebral arteriosclerosis, leading to long-term blood supply deficiency in the brain, pathological changes in nerve cells, and then brain atrophy.
Smoking has become an urgent problem that seriously endangers the health of our people.
Smoking may cause the following diseases:
I. Carcinogenesis
Second, the impact on cardiovascular and cerebrovascular diseases.
Third, the impact on the respiratory tract
Fourth, the impact on the digestive tract.
Verb (short for verb) others
Sixth, passive smoking.
4, lack of sleep
The main way for the brain to eliminate fatigue is sleep. Long-term lack of sleep or poor quality will only accelerate the decline of brain cells, and smart people will become confused.
Four major influences
1. Affect the creative thinking of the brain
A researcher once divided 24 college students into two groups and asked them to take a test first. Results The test scores of the two groups were the same. Then, let one group of students stay up late, the other group sleep normally, and then take the exam. Results The test scores of students without sleep were much lower than those of students with normal sleep. Therefore, researchers believe that a person's brain must have enough sleep to think clearly and react sensitively. If the brain does not get enough rest for a long time, it will affect its creative thinking and ability to deal with things.
2. Affect the growth and development of teenagers.
Modern research believes that the growth and development of adolescents is related to the secretion of auxin in addition to genetic, nutritional and sports factors. Auxin is a hormone secreted by hypothalamus, which can promote the development of bones, muscles and organs. Because the secretion of auxin is closely related to sleep, that is, there is a big secretion peak after people fall asleep, and then there are several small secretion peaks, while in the non-sleep state, the secretion of auxin decreases. Therefore, teenagers should develop well, grow tall and get enough sleep.
3. Affect skin health
The reason why human skin is soft and shiny is that it relies on the capillaries of subcutaneous tissue to provide sufficient nutrition. Lack of sleep will cause blood stasis in skin capillaries, and the circulation will be blocked, so that skin cells can't get enough nutrition, which will affect skin metabolism, accelerate skin aging and make skin look dull. Especially the eyes are black and prone to wrinkles.
4. cause disease.
Frequent lack of sleep can make people feel anxious and reduce their immunity, which can lead to various diseases, such as neurasthenia, colds, gastrointestinal diseases and so on. A Swedish medical researcher found that lack of sleep can also increase the cholesterol content in the blood, thus increasing the risk of heart disease. An Australian research society suggested that cell division in the human body is mostly carried out during sleep, and lack of sleep or sleep disorder will affect the normal division of cells, which may lead to the mutation of cancer cells and lead to cancer. Generally speaking, people of different ages need sleep every day. Middle school students should sleep 8-9 hours a day, and adults should sleep 7-8 hours a day.
5, few words and few words
There is a leaf area in the brain dedicated to language. Talking often can also promote the development of the brain and exercise its function. Say something rich in content, philosophical or logical. People who are silent and unsmiling all day are not necessarily smart.
6. Air pollution
The brain is the organ that consumes the most oxygen in the whole body, with an average consumption of 500-600 liters per minute. Only adequate oxygen supply can improve the working efficiency of the brain. When using the brain, it is especially necessary to pay attention to the air hygiene in the working environment.
What we usually call "air pollutants" are nitrogen dioxide and ozone. The content of sulfur dioxide, carbon monoxide and other substances in clean air is very small; But in the case of pollution, some kinds of these specific substances will increase greatly. In other words, the abnormal increase of some substances in the air will produce air pollution.
Air pollutants include smoke, steam, carbonized paper, dust, soot, coal dust, carbon dust, gas, mist, dust, particulate matter and radioactive substances.
Step 7 sleep with your head covered
With the increase of carbon dioxide concentration in the quilt, the oxygen concentration decreases continuously, and inhaling humid air for a long time is very harmful to the brain.
Some people have the habit of covering their heads with quilts, which will seriously affect their breathing. Because the head space becomes smaller after covering the head, the air is difficult to circulate, and the amount of oxygen is gradually reduced by breathing; At the same time, because the exhaled carbon dioxide is difficult to escape, the carbon dioxide around the head is getting thicker and thicker. In this way, the breathing gas can not make the lungs and blood vessels fully exchange gas, which leads to the loss of good regulation of various parts of the body and the decline of metabolic rate.
8. Harmful food
At present, some foods have negative effects on brain memory, such as potato chips, hamburgers, instant noodles and other fast food. This kind of food is easy to produce lipid peroxide, which can produce free radicals in the body and promote the decline of brain function. Lipid peroxides and free radicals are the basic substances to accelerate human aging, brain functional aging and arteriosclerosis. Medical research has proved that people begin to suffer from arteriosclerosis after entering the age of 30, but the initial symptoms are not obvious. As soon as cerebral arteriosclerosis occurs, the blood circulation in the brain will be hindered, showing amnesia or dementia. Eating high-fat, low-carbohydrate foods regularly will damage brain function and weaken memory. Because high-fat foods can affect brain function by promoting resistance to insulin, a hormone that controls blood sugar. Insulin resistance refers to the loss of sensitivity of the body to insulin, which will lead to obesity and diabetes, as well as the decline of brain function and memory. Foods lacking carbohydrates will also cut off the supply of energy glucose to the brain, hinder the transmission of nerve signals in the brain, and eventually lead to the decline of brain function.
9. Be lazy and use your head less
There is a saying that "the more you use your brain, the more sensitive you are." Using the brain scientifically and reasonably can delay the aging of the nervous system and regulate the body function through the nervous system, thus achieving the purpose of strengthening the brain and prolonging life. If you idle your brain, it will be bad for your brain and your health.
10, use your head if you are sick.
When you are in poor health or sick, you can barely persist in studying or working, which not only reduces efficiency, but also easily causes brain damage, which is not conducive to physical recovery.
