First, skipping breakfast will cause hypoglycemia and make people depressed. After a night's sleep, the nutrients in the human body have been exhausted. At this time, the blood sugar concentration is in a low state. If you don't eat breakfast, the blood sugar concentration will continue to drop, leading to pallor, weakness of limbs, listlessness, and sometimes even hypoglycemia shock. Second, it will seriously affect memory. According to experts, the energy of the brain comes from glucose, which can only be accumulated in the liver and kidneys and can only be stored for 8 hours. If you don't eat in the morning, your brain is short of energy, resulting in memory loss. Third, it is easy to get chronic diseases such as gastritis and ulcer if you don't eat breakfast. Fourth, induce gallstones. When people are on an empty stomach in the morning, the saturation of cholesterol in bile in the body is high, so eating breakfast is beneficial to the discharge of bile in the gallbladder; On the contrary, it is easy to precipitate cholesterol in bile and produce stones. A survey of women with gallstones by British scholars found that people with gallstones are related to not eating breakfast for a long time. Therefore, we should not only eat breakfast, but also attach great importance to the quality of breakfast. Some people think that "breakfast is gold, lunch is silver and dinner is copper". Eating breakfast every day is one of the elements to prolong life. Harm of skipping breakfast 1, easy to suffer from digestive tract diseases: skipping breakfast affects gastric acid secretion and bile excretion, which will weaken the function of digestive system and induce digestive system diseases such as gastritis, gastric ulcer and gallstones. 2, increase the risk of chronic diseases: start a day's work without breakfast. In order to gain motivation, an empty stomach will use thyroid gland, parathyroid gland, pituitary gland and other glands to burn tissues, which will not only cause hyperthyroidism, but also make the constitution sour and increase the chance of suffering from chronic diseases. 3, decreased resistance: malnutrition caused by not eating breakfast will lead to decreased body resistance and increase the incidence of colds, cardiovascular diseases and other diseases. 4. Accelerating aging: skipping breakfast means using glycogen and protein stored in the body, which will lead to dry skin, wrinkles and anemia in the long run, thus accelerating aging. 5, easy to get fat: Japanese sumo wrestlers are the best example. The fasting state caused by high-intensity training without breakfast will reduce the sugar in the blood, and hypoglycemia will promote the secretion of growth hormone; Eating a lot after training will make the secretion of growth hormone more vigorous and tissue fat increase continuously. If you continue this lifestyle, fat will continue to accumulate. 6, affecting learning and working ability: brain operation needs to call glucose in the blood, that is, blood sugar, which is also the only energy reserve that the brain can use. If you don't eat breakfast or the nutrition of breakfast is insufficient, the blood sugar level will be relatively reduced, and you can't deliver enough energy for the normal work of the nervous system in time. 7, easy to cause constipation: if you don't eat breakfast often, the role of gastrocolon reflex will gradually weaken, and finally cause constipation. 8, leading to malnutrition in children: children who do not eat breakfast, the whole day nutrient intake is lower than that of children who eat breakfast, and the nutrients provided by breakfast are difficult to be supplemented from lunch or dinner. What's the harm of skipping breakfast? Hu Peijin, a researcher at Peking University Institute of Child and Adolescent Health, said: First of all, after a night of digestion and absorption after dinner the day before, people must be on an empty stomach in the morning, and they need enough energy to work the next morning. At this time, breakfast is a very necessary step to provide energy. . In the morning, gastrointestinal peristalsis increases, and the secretion of various digestive glands is strengthened to welcome breakfast. If you don't eat breakfast at this time, the digestive organs will be worn out because of "idling", which is the root cause of premature aging and illness. Modern nutrition believes that breakfast should account for at least 30% of the whole day's food intake. According to research, skipping breakfast will increase the risk of ischemic stroke and heart attack. Early morning is the time of day when ischemic stroke and heart disease are most likely to occur. This is because after a night of fasting, the serum marker protein P- thromboglobulin (P-TG) increases exponentially, which can increase the activity of platelets in the blood, enhance their cohesion or adhesion, lead to increased blood viscosity and slow blood flow, and greatly increase the risk of ischemic stroke and heart attack. The average concentration of P-TG is 30mg/ml, but it is 7 times higher without breakfast. It is necessary to reduce the incidence of stroke and heart disease through diet to normal levels. Middle-aged people don't eat fried food in the morning. Cheng Bo, a nutritionist at the Nutrition Department of Beijing Medical Hospital of the Ministry of Health, told the reporter that the digestive system of middle-aged people began to decline, so we must pay attention to the quality of breakfast. It is best not to eat fried, hard and greasy food for breakfast, otherwise it will cause indigestion. Breakfast should choose foods that are nutritious and easy to digest and absorb, such as milk, rice porridge and cereal. You can also eat some eggs, preferably boiled eggs or steamed egg soup, instead of fried eggs. After getting up in the morning, get into the habit of drinking a cup of boiled water or light salt water first, which can replenish water and dilute the concentration of blood and stomach acid. It is best to have breakfast half an hour after getting up. If you eat as soon as you get up and have a bad appetite, it will directly stimulate the stomach. If you don't eat breakfast, you will easily get gallstones. Scientists study gallstones and find that it has something to do with skipping breakfast. Because the fasting time is too long, the cholic acid content in bile decreases, while the cholesterol content remains unchanged, thus forming high cholesterol bile, which leads to the deposition of cholesterol in the gallbladder and the formation of the core substance of stones. Scientists believe that people who skip breakfast for a long time and have insufficient cholic acid secretion and high cholesterol are more likely to suffer from lithiasis.
