The protein content of mutton is really unfavorable, but in terms of food properties, it belongs to "warm tonic" food and is suitable for "cold and cool" physique. If you exercise regularly and have blood in your stomach, it is a "hot and dry" type. Eating this after exercise is not good for your health. From the analysis of the gastrointestinal function of the human body, eating high-protein and high-calorie food will increase the burden on the stomach and require a lot of blood to flow through the stomach ... At this time, because the muscles are full of a lot of blood just after fitness, the blood circulation through the stomach will be blocked. Over time, it will definitely cause gastrointestinal diseases. After fitness, eat some foods rich in vitamins, such as fruits and vegetable juices.
