Spinach We all know that spinach is rich in vitamins, so many adults will cook spinach porridge or vegetable juice for their children to supplement vitamins. However, although spinach has vitamins, it must not be eaten raw, because raw spinach is rich in nitrate. Although the amount is small, it will produce nitrite after entering the human body. If this nitrite is attached to the intestine for a long time, it will become cancerous. So spinach should be cooked thoroughly before eating.

Some people have a strong smell of black fungus and eat it cold after scalding with boiling water. This cold way is very undesirable, because eating raw auricularia auricula is the most likely to cause skin allergies, and eating raw auricularia auricula for a long time can also cause gastrointestinal diseases, so when eating auricularia auricula, even if it is cold, it must be cooked in water to cool it. Like auricularia auricula, the vegetables that can induce allergies and affect the intestines are yellow flowers, so people with stingy skin and easy allergies must not eat these two vegetables raw.

Zizania latifolia contains a lot of oxalic acid.
