I think of it similarly to the "fish in water" story - there's a lot of things about your perception that you won't can't really realize until they're changed - like how your nose is visible to your eyes and each eye has a blind spot - your brain filters out anything that's always there because it's not important to survival A sugar high does reveal a deeper truth about the way we enjoy sweet things, that you would never even know you're missing if you never had sugar. This is also kinda why people react so dramatically when they try a new food or see colors in different ways - it's a wild experience to find out that the way you've been perceiving the world isn't the way it actually is, it's just a narrow slice of reality. "Narrow slice" is a phrase you could look up to read more about this idea, the book Flatland also does a great job of explaining it, or thinking about how other organisms only see infrared light and we can't see it at all
