The spicy ingredient is organic sulfide, which is volatile and can irritate the nose and eyes, which is why people often "cry like rain" when cutting onions. Organic sulfide is soluble in water, so when cutting onions, dipping the knife in some water can alleviate the symptoms of "tears". Studies have shown that organic sulfides have antibacterial, anticancer and anti-inflammatory effects, and at the same time they can scavenge free radicals in the body and have antioxidant effects. The content of organic sulfide will decrease when onions and scallions are cut and dried for too long or cooked at high temperature. Therefore, the best way to eat onion vegetables is to eat them raw or stir-fry them for a short time.

It is usually stored in garlic cloves in the form of alliin, and it will be crushed to form allicin which can stimulate the gastrointestinal tract under the action of alliinase. Therefore, it is best not to eat garlic raw on an empty stomach, otherwise it will easily damage the gastric mucosa. Allicin can promote the absorption of vitamin B 1 in human body, and has the functions of sterilization, blood lipid reduction and anticancer. Garlicin heating will also fail, so try to eat garlic raw, and it is best to mash it for 10~ 15 minutes before eating, which is more conducive to the production of allicin.

The main pungent substance is capsaicin, which produces burning sensation by stimulating oral mucosa and trigeminal nerve. Sweetness can mask and interfere with spicy taste, acid can neutralize alkaline capsaicin, and casein in milk can combine with capsaicin. Therefore, it is very useful to dip in vinegar, drink a bowl of cold sweet drink, or drink a glass of milk when it is spicy. Capsaicin can help people resist cold and humidity, and also help reduce the risk of heart disease and atherosclerosis. Chili is best cooked, because raw Chili contains a lot of capsaicin, which may irritate the oral cavity and gastrointestinal mucosa. After heating, the irritation to the gastrointestinal tract will be reduced.

Some medical and nutrition experts in China investigated Hunan and Sichuan provinces and found that the incidence of gastric ulcer in these provinces and regions, which generally like to eat Chili, is much lower than that in other provinces and regions. This is because pepper can stimulate the release of prostaglandin E2, which is beneficial to promote the regeneration of gastric mucosa, maintain the function of gastrointestinal cells, and prevent and treat gastric ulcer.
