How is it like to look at a strawberry tray knowing that it could kill you? All right, there are also less serious food intolerances: you may as well be scratching your kin for 23 minutes because you ate a cherry. You can live with it. But food intolerance is also when you cannot stand the person sitting next to you because he is eating its soup loudly. Or when at the Easter lunch with your family you are always sitting in front of the same uncle whose mere presence makes you uncomfortable. It is an intolerance which reveals itself while eating, so it can be considered a food intolerance.
