When doing long-distance running, weightlifting and other sports with a large amount of exercise, the human body consumes a lot of energy, while the energy and nutrition in chocolate are relatively dense, which can meet the energy of the human body in the shortest time and make the blood sugar in the muscles and liver in the most saturated state.

The ingredient that gives chocolate its unique charm is polyphenol, which is a natural ingredient in cocoa beans and a strong antioxidant. It can inhibit "impurities" in blood, prolong the action time of other antioxidants in human body, such as vitamin E and vitamin (vitamin food) C, and promote vasodilation. Polyphenol is a compound with potential health care (health food) function.

Therefore, before doing physical exercise, people had better eat some chocolate, especially dark chocolate. When people don't eat before exercise, eating some chocolate is a good choice. Of course, this is not to encourage people not to eat before exercise.
