4. Mushrooms
Mushrooms have proteins which can easily be destroyed by enzymes and microorganisms, according to the European Food Information Council.
If they are not stored properly, mushrooms can deteriorate quickly and cause an upset stomach after reheating.
However, says the council: “If they are stored in a fridge and for not more 24 hours, it is in general no problem to reheat mushrooms again at recommended temperatures of 70 C.”
