Often skipping meals will bring a lot of harm to human body. (a), often do not eat easy to suffer from digestive tract diseases. After a night's sleep and a hard day's work, the food in the intestines has been digested and needs to be supplemented urgently. If the diet is regular and irregular, today's food intake will inevitably increase greatly, resulting in excessive gastrointestinal burden, leading to gastric ulcer, gastritis, indigestion and other diseases. (2) Frequent skipping meals will reduce brain function and affect brain development. When you are hungry, your blood sugar will drop, which will cause brain disorder, dizziness, inattention, memory loss, fatigue, and even affect your brain function, leading to mental decline. (3), often do not eat food with high cholesterol in the body. Cholesterol is 33% higher than normal diet, and all children with high cholesterol have fat lines in their blood vessels, which is an early sign of atherosclerosis. (4) Long-term irregular diet is also prone to gallstones. When people are on an empty stomach, the cholesterol concentration in bile is particularly high. Under a normal diet, the gallbladder contracts and cholesterol is excreted with bile. If you don't eat it often, your gallbladder won't contract, and it will be easy to get gallstones after a long time.
