We used to occasionally have to put our kids on “sugar fast” when they ate too much sweet stuff because they then couldn’t taste sweet in lightly sweet stuff. So their palate needed to be recalibrated. I’ve had to do the same with salt before.

And I am desensitized to spicy things but like that because I can appreciate more foods that way, or more of the ones I tend to like. But surely it’s a form of damage.
