It’s not bad to have a fear of certain things. But if you are afraid of certain food items, it is something that you might want to analyse. While it’s hard to digest the fact that people can be afraid of food, there are even names for these phobias.
One such phobia is brumotactillophobia. People who get irritated when two different food items on the plate touch each other are probably suffering from this.
Meanwhile, thermophobia is the fear of getting your mouth burned with hot food. The exact opposite of this is frigophobia which is the fear of cold things. And yes, this also includes fearing ice creams.
