This is a bit of a TAAT so apologies!
A very beleaguered OP currently has a thread running about her fussy-eating husband. Loads of posters have piled on to proclaim they are emphatically 'Not Fussy Eaters', but wouldn't eat pulses, most vegetables, vegetarian food, etc.
To me they are fussy eaters. I understand about conditions involving anxiety around certain foods and sometimes the need for limited diets, but to me, 'non-fussy' eaters eat pretty much anything (barring vegetarianism or religious constraints).
Having said that, I'll eat any food, as long as it's well cooked, I've had some dreadful meals that I really didn't want to eat. I'm not a human dustbin!
