When you have certain food poisonings why does it cause throwing-up or stomach pains?

The body tries to get rid of anything that could be harmful. Humans, like animals, will through up anything that the stomach does not like. It is a response to limit the damage by toxins and micro-organisms.

Biologists have studied the eating habits of scavengers, like hyena's, who often eat dead animals in various degrees of decay. These animals are probably more tolerant to bacterial toxins, but an important safety feature is that they will nibble at something, and very rapidly will through up anything that does not go down well. In this way they prevent being poisoned.

Unfortunately, this biological response is not as strong in humans, so that we may eat something that really makes us sick and it is normally digested. But in most cases where you feel sick, be glad to be rid of the stomach content that otherwise would cause you even more trouble!
