In the face of delicious food, people will inevitably have the urge to eat a big meal, and some people will not even eat chopsticks. However, a recent study by scientists found that long-term satiation of the human brain is more prone to premature aging. It is said that long-term satiety can cause excessive calorie intake, excess fat, and elevated blood lipids in the body, causing an increase in a substance called "fibroblast growth factor," which leads to atherosclerosis in the cerebral arteries and supplies oxygen to the brain. Reduced nutrients cause people's memory to decline, premature brain aging and mental retardation. Then, where does the hunger and fullness of people come from, and what other harms do they have for long-term satiety? What kind of dietary approach do we really need to make? Modern medical research has found that there are so-called hunger centers and satiety centers in the human brain. Together with the cerebral cortex, they effectively control human food intake through the gastrointestinal tract reaction. When the blood sugar falls and the stomach emptys, the cerebral cortex receives a hunger signal, and the nerve center of the cerebral cortex sends a command to the hungry center in the hypothalamus and sends a command to suppress the satiety center, so that the person becomes conscious. Eat. When a person eats a certain amount of food and the gastrointestinal tract feels bloated, he sends the satiety signal back through reflection, and the cerebral cortex sends a “satisfaction†to the hunger center and the satiety center respectively. The instructions thus stop eating. Once researchers had done related animal experiments, they discovered that after destroying the satiety center in the animal's brain, the animals consumed more food, their food intake increased significantly, and their weight increased significantly. When energy reached a new balance, stop. On the contrary, the hunger center is destroyed, and animals do not eat, resist food for a long time, and die due to failure. However, the amount of food consumed is also related to people’s eating habits. Some people are always greedy and eat more often than not because of hunger. They are long-established habits. When people are eating, if they eat too fast or take too long, they may over-eating. It is also an important reason that it is difficult to control appetite in the face of favorite foods. When people eat or eat while they want to think of something else, they often spend a long time, an hour, two hours or even longer, so that they constantly eat, and because attention is often focused on chatting or thinking about something else. Go up, so the reaction to satiety is relatively slow, resulting in excessive food intake and over-eating. In addition, if you devour when eating, eat faster than the speed of the signal of satiety, obviously the amount of food you eat is enough, but the brain has not yet received a signal, it will continue to eat, food over- Ingestion. In daily life, we can still have this kind of experience. We obviously do not feel hungry, but because we have delicious food in front of us, we can’t help but want to eat a little. This can easily make people overeat. The large amount of food does not mean that there is a lot of nutrient intake, and long-term satiety may cause a series of reactions in the body and bring about various diseases. A person who is full does not necessarily mean that he needs enough nutrients, such as eating a meal with an unbalanced diet. The food is large and fat, but the intake of trace elements or vitamins may not be enough. It can also be called hunger. It is called hidden hunger. The most direct consequence of overeating is the increased burden on the gastrointestinal tract. If the stomach is always in a state of fullness, the capacity of the stomach will be too large, the digestion and absorption function will decline, and it will cause indigestion. However, large amounts of fats and proteins that are ingested cannot be used effectively, and they will be stored in large amounts, resulting in excess nutrients and causing diseases such as obesity, diabetes, and hyperlipidemia. Some studies also believe that the more energy the human body ingests, the more reactive oxygen species (free radicals) that are harmful to the human body and the more quickly people age. Eating less can reduce the production of reactive oxygen species and protect cells from their harmful effects, thus delaying aging. In addition, because modern people generally love to eat acidic foods such as meats and refined cereals, if they are consumed excessively, it will cause the body's internal environment to become acidic and form acidic bodies, providing a breeding ground for various diseases. There are also scientific standards for how much to eat each day, but it is necessary to combine different people's specific circumstances. For a 1.70-meter middle-aged man, who has normal weight and physical labor is not very heavy, then his daily energy needs is about 2200 kcal, of which food should account for about 50%, and the number is about 300-350 grams. Around, 150 grams of meat, including all the meat, plus an egg and 250 milliliters of milk, there should be an appropriate amount of soy products, and other such as mushrooms, fungus, kelp, seaweed, shrimp, etc. should always eat. As for oils and fats (including seeds of oil and plants), it is recommended that you do not eat fried foods, and the amount of oil you eat should not exceed 30 g/day, ie 3%. With respect to vegetables and fruits, it should be the most in terms of weight, and it must reach 750 to 1000 grams. In addition, such things as snacks, desserts, and wine should be appropriate. If physical labor is a bit heavy, then these things can also be increased in moderation. From an age point of view, the food intake of children in puberty will definitely be higher than this, because they will have to grow up and have a larger amount of activity than adult men. Older people will have to reduce it. Of course, each person's physical condition is different, and the amount of food they eat will vary, mainly depending on their specific circumstances.
