Scientifically speaking, pepper was introduced into China from abroad. It is said that the foreigners who brought Chili peppers to China were not kind, but I didn't expect China people to become addicted as soon as they ate them, so Chili peppers took root and sprouted in China. Pepper itself is tasteless, and taste buds perceive the heat released by pepper. The temperature of this heat is directly proportional to the spicy degree of pepper, that is, the hotter the pepper, the greater the stimulation to our taste buds, and it will make people feel pain when burned to a certain extent. The reason why people like to eat Chili peppers is not because they are too masochistic and like to make trouble, but because when stimulated, they will secrete some substances to protect themselves, that is, paralyze their nerves. This "self-paralysis" is similar to the feeling of drinking a little, and it is a small state of excitement between half dream and half waking. Pepper contains a substance called capsaicin, which acts on the central nervous system to make people excited, basically similar to drugs, because capsaicin can make people addicted and exercise people's resistance to peppers, that is, people who love peppers will get hotter and hotter and more addicted. From the perspective of health, according to relevant information; Pepper contains essential nutrients for human body, such as vitamin C 198 198mg per 100g pepper, and the content of vitamin C ranks first among all kinds of vegetables. Protein 1.6 g, 0.7 g more than tomato; Contains 0.2 grams of fat; Contains 4.5 grams of carbohydrates, 2 grams more than tomatoes; Calcium12mg; 40 mg of phosphorus; It contains carotene1.65g. Medical experts believe that pepper can relieve cold pain in chest and abdomen, stop dysentery, kill parasites in stomach and abdomen and control heart disease and coronary atherosclerosis. Pepper can also promote blood circulation, increase vascular elasticity, reduce the chance of arteriosclerosis, and help prevent cardiovascular diseases. Pepper is also rich in vitamin C, which has antioxidant effect, can enhance the body's resistance and delay aging. Eating Chili can stimulate appetite and help digestion. After eating pepper, capsaicin can stimulate oral mucosa, accelerate gastric peristalsis, promote saliva secretion, stimulate appetite and promote digestion. In terms of weather, it is cold and humid in winter in the south, and pepper can play a role in driving away cold and heating and preventing rheumatism. Another example is Sichuan, where the weather is humid, so Sichuanese like to eat spicy food. Pepper is also a kind of warm food. In traditional Chinese medicine, the classification of pepper is warmth. People in Guangdong, Fujian, Shanghai and Zhejiang don't like spicy food very much because they are close to the sea.
