Wow. Never heard that term. I was always just a "picky eater" as a kid.
Spinach and some other veggies - I'm fine with almost everything raw. Can't stand it cooked. Yet people complain about that. WTF? I'm asking you to NOT do any food prep - no energy to cook/heat it up - there's no wasted effort, and it's good for you. I'd still get push back from family over the years as a "picky eater".
My brother got us a juicer, and I'm juicing up loads of carrots, spinach, celery, beans, greens (collard/turnip), etc. Yeah, that definitely doesn't taste awesome, but in some ways, because of the mix, it doesn't taste strongly of anyone type of food - they sort of cancel each other out a bit. It's not a great taste, but doable, and it's healthy.
Coffee - that took a while to be an acquired taste. Why do this but not beer? A) cheaper. B) caffeine kick is more useful to my daily life. I'm not a coffee addict - 2-3 per week is a lot - but generally cheaper to add on to a breakfast meal than a beer is with a dinner. I prefer flavored coffees/mochas/etc, but coffee with enough cream/sugar is workable.
