You eat a new food and that night become ill with nausea and vomiting. Later, you experience nausea whenever you taste or smell the new food. Why did you not associate your nausea with the cues of the room, the people present, the bathroom, and so on

You were biologically predisposed to associate taste and nausea.

Explanation:

The nausea and vomiting was caused by the new food ingested. It has nothing to do with the environment. The food isn’t compatible with the body system. This is the reason for the vomiting and when such individual tastes or smells the food, a signal is sent and the body reacts the same way as in the first encounter.
