How does the human body perceive being full? Is it affected by the speed of eating?

Scientists from the agency, as well as the French Institute of Agronomic Research and other institutions, have studied people's physical reactions when they eat and noted that the common feeling of "fullness" is that the intestinal tissue senses the body's "fullness" by absorbing glucose from food, the other national scientific research center said in a communiqué. When glucose is released into the blood vessels of the intestinal tissue, special cells in the blood vessel wall of the intestinal tissue can sense this phenomenon, and these special cells are connected to the nervous system and transmit glucose information to the brain through them. After sensing glucose information, the brain sends out instructions to gradually reduce the feeling of hunger.

I remember watching the American TV series "CSI", in which there was a person's nerves who couldn't transmit the message of fullness, and he forgot what he was called sick, but he felt hungry, but he died!

What the stomach senses, the speed is slower than the actual fullness, so it is easy to eat more, so it is better to eat slowly.

When you can't eat, you know if you're full. The speed of eating is taken by the individual.

After eating, walk a hundred steps and live to ninety-nine.

People who are full have less blood in the gastrointestinal tract, which affects the decomposition, digestion and absorption of food in the gastrointestinal tract.

Of course, as the saying goes, the plan of the day lies in the morning, the morning is the beginning of the day, you have to eat well, and you have to eat enough at noon because the workload in the afternoon is very large, and the night is mainly sleeping, so you should eat less.

The scientific basis for this is that the exercise consumption during the day is relatively large, but at night and less.

This is based on science, breakfast should be nutritious, lunch needs to be full, and dinner is too much to digest.

He should eat nutritious, have a full lunch, and eat a little less for dinner, which is good for his health.

This is because generally speaking, we have a large amount of body in the morning and afternoon, but we consume less in the evening.

This is scientifically based and is determined according to the different digestive abilities of people in each time period.

Yes, it's based on the science that our bodies change over time.

This should be stated according to the body's digestive capacity as well as the time period.

This is based on science, and it is determined by experts according to the person's ability to digest.

Will be thirsty, close to the brink of death, the limit of hunger is 6-7 days.

If it is a shower, there is nothing bad, and the others may have more or less effects on the stomach and intestines, which will cause indigestion.

Wow!! The Yan family is a class of scientists, oh, and if you are weak, you are a Gangara!! You Sichuan is weak and blown by the wind!!

It is not advisable to take a bath immediately after a full meal: Bathing immediately after a full meal can affect digestive function.

When bathing, ** blood vessels dilate, blood flow is vigorous, if you take a bath immediately after a full meal, the blood flow of the digestive tract is relatively reduced, and the secretion of digestive juices is reduced, so that the digestive function is low.

Therefore, it is not advisable to take a bath immediately after a full meal.

However, it is not advisable to take a bath on an empty stomach, because it is easy to cause hypoglycemia and shock.

Therefore, it is best to take a bath when you are not full or hungry.

When a person has just finished eating, a large amount of blood flows into the stomach, and other parts will be ischemia, and when washing the hair, the head should be lowered, which will cause the head ischemia to be more serious. If you take a bath on an empty stomach, it will also cause adverse effects on the stomach. On the contrary, if you go to take a bath just after eating, the hot water will cause a large amount of blood to flow to **, and it will also cause ischemia in the stomach that needs blood, resulting in indigestion.

The correct way is to take a shower half an hour to two hours after eating.

Physical effects: The increase in fat content will increase the burden on the body, walking and exercising will make you gasp and not move as flexibly as before, and it is also easy to produce high blood pressure, diabetes and fatty liver, and will also increase the burden on the heart. Psychological Effects:

Weight skyrocketing and fat appearance are likely to lead to a temporary inability to accept the change in one's image, resulting in low mood and low self-esteem.

We all know that proper obesity is good for our body, but when the weight skyrockets, our heart and stomach will be affected, and the sudden surge will put more pressure on our hearts, so when we eat, we can not let ourselves eat too much.

Weight gain can be said to be wearing clothes, which has a special impact. It may be a good-looking dress, but it can't be worn like this, and it looks very strange.

I often feel sleepy after lunch, is it because the blood is concentrated in the stomach and away from the brain?

Not really. Many people think that after eating, the blood of the whole body is concentrated in the digestive system to help gastrointestinal peristalsis and digestion, which will cause insufficient blood supply to the brain and make the brain lack oxygen, and people will feel sleepy, but this is not scientific.

As the most important organ of the human body, the human body will give priority to ensuring the blood of the brain**, if it is really as many people think that the brain is short of oxygen due to the reduction of blood supply, then the person should feel dizzy instead of simply sleepy. Foreign studies have indeed found that the blood flow to the brain not only does not decrease but increases after meals.

So why is there "food sleepiness"?

This is mostly related to the endocrine status of the human body after meals. When a person eats a high-carbohydrate food, the blood sugar rises, which inhibits the hypothalamus from secreting an appetite hormone, which is low in protein hormones, making the person feel tired and drowsy.

In addition, researchers in the United States found that the secretion of cholecystokinin may be related to drowsiness after meals, and the researchers tested the amount of cholecystokinin secretion and drowsiness scale scores of the subjects before and after meals, and found that there was a positive correlation between the two, that is, the more cholecystokinin secretion, the more sleepy people were. If the food you eat is too greasy, you will secrete a lot of cholecystokinin, which may also be the reason for feeling "sleepy" after eating.

Frequent malaise after meals is likely to be caused by hormones in the bodyCholecystokinin, a study from Stanford University found that cholecystokinin secreted in the human body usually rises within two hours of eating, and after two hours, the amount of this contractile secretion decreases. The higher the cholecystokinin level, the more likely it is to get tired.

In addition, the higher the fat content, the higher the cholecystokinin level and the more likely it is to be drowsy.

Orexin, after the human body eats, in the process of digestion and absorption, blood sugar will increase after eating, and at the same time inhibit the secretion of orexin in the body. When the orexin content is reduced, the human body is prone to drowsiness and does not want to move. With a high orexin content, the human body is more awake and active.

As a result, especially when eating foods with more digestible starches, blood sugar rises relatively quickly and drowsiness is more likely.

Insulin, after a meal, the glucose in the food is absorbed by the body, and insulin is secreted to help control blood sugar. Insulin promotes protein synthesis and tryptophan in the human body increases. Serotonin is formed in the brain and can further form a fade.

Melanin, which makes people feel drowsy.

In addition, insulin can also promote the body's potassium ions from the blood into the cells, and if the body is in a mildly low blood potassium state, the body can also experience fatigue and drowsiness.

How can I alleviate food troubles? control the "quantity" of eating "seven" meals per meal; Replace white foods with whole grains, beans and potatoes. It is recommended that whole grains account for about 1 3 of all staple foods.

Increase foods that are high in dietary fiber, such as green leafy vegetables, and cut back on high fat. High-sugar food intake. At noon, after lunch, you can spend about 15 minutes, which not only effectively relieves the state of sleep, but also reduces the secretion of stress hormones in the body and improves the efficiency of afternoon work.

Generally speaking, this is because people will have a feeling of fullness after they are full, and then they will feel very sleepy and want to rest.

That's because the brain starts to digest food at this time, so it gets sleepy.

Because after people are full, they will feel very comfortable, and the body will also take in nutrients.

In fact, it's normal to be full and sleepy, after all, you eat carbohydrates.

There are limitations, just like the liver hangover, too much alcohol will not work.

It will not be excreted, but will remain on the body as fat.
