idiosyncrasy 

an abnormal physical reaction by an individual to a food or drug.

The term "idiosyncrasy" typically refers to a personal habit or quirk, not a medical reaction. However, there are some related terms you could use:

Hypersensitivity: This describes an abnormal sensitivity to a substance, including food or drugs.
Adverse reaction: This is a more general term for any negative response to a substance.
Idiosyncratic reaction: This combines the idea of an individual reaction ("idiosyncratic") with the general concept of a response ("reaction"). It's not as common as hypersensitivity, but it conveys the same meaning.
Here's an example sentence using "hypersensitivity":

John suffered from a peanut hypersensitivity, causing him to break out in hives whenever he ate peanuts.
