To ensure a good breakfast, generally choose light and nutritious food, such as soybean milk, eggs, steamed bread, fruit and so on.

You can't eat breakfast before running in the morning because food needs to be digested in your stomach. After breakfast, the whole body's blood will be concentrated in the limbs, and the blood in the stomach is almost zero, so only the stomach wall will directly rub the food in the stomach, and then the symptoms of stomach pain will appear after running in the morning, and gastritis and even gastric ulcer will appear after a long time.

After meals: At this time, more blood flows to the gastrointestinal department to help food digest and absorb. At this time, exercise will hinder the digestion of food, and over time, it will lead to diseases of the gastrointestinal system and affect health. Therefore, it is best to sit still or lie down for 30 ~ 45 minutes after meals and exercise.

Extended data:

The intensity of exercise in the morning is generally not too great, nor too great. Most of them keep exercising for about an hour or two, and their heart rate varies from 120 to 180 times per minute. At this time, you have to wait 15 to 30 minutes after your morning run before you can have breakfast. If the intensity increases, you need to extend the rest time.

Because the cerebral cortex center responsible for skeletal muscle and myocardial movement is in a relatively excited state during exercise, while other parts are in a relatively inhibited state, gastrointestinal peristalsis is weakened and digestive juice secretion is reduced.

Eat some carbohydrates such as bananas and steamed buns and drink light salt water before running in the morning. On the one hand, it ensures the adequate supply of blood sugar; On the other hand, the decomposition of sugar can promote the burning of fat; But also can prevent dehydration in the morning run.
