If the creeping cauliflower insects are not cleaned up, they will hide inside and be invisible. Whether there is something wrong with your stomach after eating it is another matter, but don't you feel sick? Also, there are many pesticides in vegetables now, so not every cauliflower is organic. So for the sake of health, it's better to cook before eating. In addition, if it is soaked in salt water and effectively sterilized, it is edible, but it is limited to fresh cauliflower. Old cauliflower can't be chewed, which easily leads to indigestion.

Common vegetables to be blanched before eating are: spinach, bamboo shoots, broccoli, cauliflower and so on. (Spinach and bamboo shoots contain oxalic acid, which combines with calcium in the stomach to form calcium oxalate, which will interfere with the body's absorption of calcium; Broccoli and cauliflower are easy to digest because of their rich cellulose after blanching. If you eat vegetables raw, you must disinfect them first. Rinse the vegetables with water, soak them in a small amount of salt or vinegar for 10~20 minutes, then drain the water and plate them. When it is cold, add vinegar, garlic, salt, Jiang Mo, mustard, etc. Used for seasoning and sterilization.

Which vegetables should be cooked?

1. Green beans. If the green beans are not cooked, the saponins in the beans will stimulate the digestive tract, and the beans contain thrombin, which has a clotting effect. Mung beans contain nitrite and trypsin. Raw food can stimulate the human stomach, causing food poisoning and gastroenteritis. So the green beans should be cooked thoroughly.

2. Day lily. Day lily is also called day lily. Fresh daylily contains colchicine, which will be oxidized into diclofenac in human tissues. Diccolchicine is a highly toxic substance, which can poison the gastrointestinal tract and urinary system of human body and seriously threaten health. So you can't eat it raw, you must process it and dry it. Blanch with boiling water before eating, and then soak in cold water for more than 2 hours. Heat it thoroughly when eating, and don't eat too much at a time.

3. Ginkgo biloba. Ginkgo biloba may contain cyanosides, so be careful when eating. Cyanide itself is non-toxic, but when the structure of plant cells is destroyed, β -glucosidase in cells will hydrolyze cyanide to produce toxic hydrocyanic acid, which will cause acute poisoning. Cyanoside is afraid of heat, and it will be destroyed once it encounters high temperature. Thorough heating is the most effective way to remove cyanosides. It is found that boiling can remove more than 90% cyanosides. Therefore, in order to prevent ginkgo poisoning, it should be fully heated before eating. The heated ginkgo biloba is not only safe and secure, but also tastes better.
