I think they’re asking because you can develop taste aversion by eating something and getting sick (even if the sickness is completely unrelated).
My sister got H1N1 when it was proliferating, and she had a box of nilla wafers before the symptoms started hitting hard. Now she inexplicably can’t eat a single nilla wafer.
How do you find out if you are a supertaster? I’m curious because growing up I couldn’t stomach any vegetable that was bitter. Broccoli, brussel sprouts, celery, etc. were enough to make me gag just from the flavor. Nowadays, I can cope with the bitterness by focusing on other flavors and textures but I’ve definitely been in positions where I have a single bite of celery and then can’t muster up the courage to eat for a solid hour.
