My friend introduced this term/phrase to me a couple of months ago: “psychological allergies.” Basically, these are “allergies” we have against certain foods for psychological reasons, i.e., the taste of certain foods makes us feel sick, etc. We are not really allergic–just have an aversion against the food.
Recently, I have developed a psychological allergy against oranges. Why? I received too many oranges during Chinese New Year and became sick of eating them day in, day out. I had way too many and had to give away some oranges to friends and homeless people. Granted, I can still eat oranges, but I feel sick when I eat them now. Something about the texture makes me feel queasy these days.
