When you stop eating sugar for a while, food like fruit starts to taste delicious, and when you go back and try to eat sugar again, you find that everything is way over sugared. It is actually distasteful. Uncomfortably sugary.
Totally agreed. Same with salt.
But that means that we have to learn to be happy with existing in the middle of our taste spectrum rather than at the edge, and to learn to see extremes as problematic rather than delicious ;-)
But the edge is in constant motion! You adapt to the sweetness and then you crave more. Just human nature I guess.
Yes, that's how neurons work. We crave the edge, but the edge is bad for us!
