perception or even in the head ..maybe it stems from what you are fed as a kid ??
I'm reliably informed that if you eat something your taste buds will adapt to it so something that you hate , like celery ,will as you get used to it become OK and palatable for you ... of course the drawback is that most people if they don't like something won't keep eating it That's what my wife keeps telling me, but it's simply not true. At BEST I find I can get to tolerate something, but never to actively enjoy it. This is what's happened for me with most green veg outside of the aforementioned spinach and spring greens (which are utterly beyond redemption) - I've learned to eat stuff like broad beans, runner beans, broccoli, courgettes, lettuce - as a sort of medicine, because I know they're good for me, but I make sure I get them out of the way first, before tucking into the only NICE part of a meal, i.e. the meat and potatoes.
But she actually finds that stuff mouthwatering, as I would only for a steak, a chip butty or a big bar of Dairy Milk. It just baffles me how this can be so.
