If you truly mean tolerate, then your sensitivity might be a bit in the extreme. I wouldn't expect anyone to be bothered by eating a bit of pure sugar or honey even if they prefer their food unsweetened.

But yes, a lot of food is excessively oversweetened (it's a cheap way to win kids and therefore long-term habits), and you become desensitized to anything you constantly taste and will notice differences when you stop.

However, everyone has different taste, both genetically and because of whatever else they eat and is more or less sensitive to, so there's no such thing as "flavor perfectly enhanced", only your own particular preference for a particular dish. Someone eating less sour or being genetically predisposed to bitter might violently disagree with your flavoring for example.
