A. Drink plenty of water: food poisoning generally causes vomiting, and gastric juice will be spit out when vomiting, resulting in water loss or dehydration. Drinking water also helps to alleviate the acid-base imbalance.

B. Vomiting: It will cause more water loss or dehydration and acid-base imbalance (gastric acid ~ ~). Therefore, vomiting is not the way.

C taking laxatives: it will cause more water loss or dehydration.

D. Detoxification: It would be nice to have a universal antidote, but the cause of poisoning is generally unknown (it may be that the food itself is toxic, or it may be caused by bacteria or viruses).

E. keep warm: it helps to recover.
