As the saying goes, a day's plan lies in the morning, and students' important courses are arranged in the morning, so breakfast becomes the energy guarantee for morning study. From dinner to the next morning, 7-8 hours have passed, food has already been emptied from the stomach, digested and absorbed by the small intestine, and blood sugar has also dropped to a lower level. At this time, the blood sugar level can no longer provide enough heat energy for intense study in the morning, nor can it ensure the brain's demand for sugar. People will be listless, weak, inefficient in learning, slow in thinking and poor in memory. Some people think that skipping breakfast does not affect learning efficiency. This is an illusion because the liver is working. When breakfast is not eaten and there is no supplement of calories and sugar, in order to ensure a certain blood sugar concentration, the body will use glycogen stored in the liver to decompose it into glucose and release it into the blood.
The glycogen stored in the liver is only enough for the body to use for 3 days under the condition of complete fasting. Because the liver lost its stored sugar, fat took advantage of it, fat deposition appeared in the liver, and fatty liver appeared for a long time. Because the liver loses sugar, it loses the protective effect of sugar on liver function and is easily infected by bacteria and viruses. Therefore, in the state of malnutrition, liver function is also easily damaged. So breakfast is very important!
The main component of China people's staple food is starch, which is characterized by rapid absorption and metabolism in the body, rapid increase of blood sugar and decomposition and utilization in the body. Simply eating staple food will soon make people feel hungry. At about 10 in the morning, there will be inattention, fatigue and even hunger in class. Therefore, in addition to the staple food, we should eat some milk, eggs or bean products for breakfast, and also eat a proper amount of vegetables. These foods not only provide a variety of nutrients, but also stay in the stomach for a long time and digest slowly, which can continuously maintain blood sugar levels.
