I'm Picky With Food. Deal With It

When it comes to food, my mother does not take "no" for an answer. It is her chief belief that I'm ridiculously fussy about my food, and it is her duty to (1) disseminate this information to anybody who mentions food preferences and (2) condition me to like them with repeated, forced exposure. (Well, not so much anymore, since the last repulsive food she exposed me to a few times caused severe allergic reactions for two nights in a row, a few months back). Obviously, the latter doesn't work, because I have not managed to like anything that I was repulsed by upon initial contact, but more annoyingly, everybody who has heard this now assumes that I was spoilt rotten as a child, and am now insufferably, reprehensibly picky.

( I choose to believe that there is an in-built biological reason why people like or dislike certain foods. )
