That's your problem: you are doing it as a "I'm righteous" thing rather than being externally considerate and just saying "don't like it... don't want to eat it..." and not passing judgment on them by your "diet crusade".

If you can eat eggs, why not make some scrambled eggs? Why don't you let people know you dislike cheese, bread gives you bloat, and you only like meat and limited veggies. Heck, create an OCD picky-eater persona and just get into the role?
