The biggest shift in taste (for the worse) due to sweeteners was coco pops. My grandmother used to feed me these for breakfast in the 80s and the chocolate taste was nothing short of magical. I can’t begin to describe it but imagining it actually places me back in that time. Wind forward to the mid 90s and the “great new taste” as it was marketed as had ruined a childhood staple forever more. I feel sorry for today’s kids because they will never know what it was like to eat coco pops on the 80s.
