reported by Zhang Chu.com on March 6, 2019 that after Mr. Zhang was eating noodles and running, his skin was chewed, and large red "blubbers" appeared and gradually spread. He also had a rapid heartbeat, dizziness, difficulty breathing, and was unstable. He was sent to the first aid agent to escape from danger. The doctor initially diagnosed Mr. Zhang suffering from food-dependent exercise-induced allergic reaction. We don’t care about what the professional term “food depends on exercise-induced allergic reaction” is, and whether you can eat before exercise and how to eat this is a very important thing to pay attention to. One of the suggestions Mr. Zhang's doctors gave him was to avoid exercising within 2-3 hours after eating.
In fact, everyone should be clear that it is not advisable to eat too much food before running. Because under normal circumstances, after too much food is injected, a large amount of blood will flow to the stomach, providing the stomach with enough oxygen and energy to digest food. And when exercise, blood flows to the limbs. If you move immediately after eating, the blood must not only flow to the stomach to ensure digestion needs, but also flow to the limbs, which will cause you to lose sight of one thing and make your body at a loss. In addition, after eating, the stomach becomes thinner, which greatly exerts a lot of movement, causing the stomach to become unbalanced in the abdominal cavity, which can easily cause stomach pain, stomach sagging, and other diseases.
Is the consequence of eating too much before exercise so severe? So, can you not eat before exercise? The answer is no. Eat a little before exercising, which has something to do with blood sugar. During intense exercise, the body will consume a large amount of glycogen (the most important energy-supplying substance in the human body) in a short period of time. If the carbohydrate in the body cannot be replenished in time, people will feel weak, anxious, and palpitations, and their blood sugar index will decrease. In addition to the above symptoms, people with hypoglycemia may also cause convulsions, coma, etc.
The consequences of not eating are also quite serious. So what can not only replenish energy for the body, but also avoid abdominal exercise? The first choice is to remove fat milk. Fat milk does not increase fat and can also provide a large amount of sugar. The second is banana. Bananas can fill their stomachs and have high heat content, and are also relatively high in sugar and debris, making them ideal for sports food. If you are a person with hypoglycemia, you can also bring a few sugars to prepare for timely needs.
