Don’t eat immediately after exercise, usually eat again after an interval of more than half an hour. Blood is often distributed to the body surface and muscles after exercise, and the blood supply in the stomach and intestines is relatively small. If you eat too quickly, due to the relative lack of blood supply, resulting in insufficient secretion of digestive juices and a lack of digestive enzymes, it is easy to have indigestion, food accumulation and other problems, which will also affect the absorption of nutrients. Therefore, you should rest sufficiently after exercise, usually for more than half an hour, and eat only after your digestive function has returned to normal. It is recommended that when eating after exercise, try to choose foods that are easy to digest, avoid foods with too low a temperature, such as ice cream and cold drinks, and avoid spicy and irritating foods, such as barbecue and chili peppers, in order to protect the health of the digestive system.
