It is all so stupid. I almost never got sugar fill stuff like this when I was a kid. Mom and dad knew better. They didn't have to toss us outside. We wanted to go out. We knew if we stayed in they would put us to work cleaning something.
When I had kids we got some of these sweets stuff for them but it was not for breakfast it was used as a snack. My wife set a standard for how much sugar it could contain and how much they little nippers could get in one sitting. When i was at the store with the kids I couldn't remember what the cutoff was. (12 grams of sugar I think.) But the kids knew and if I was looking at the wrong box of stuff they pointed it out and showed me what they could have.
And they played a lot outside. If not we put them to work cleaning something. They only got to watch tv or play video games after they did something to offset it. (Homework, play, so on.)
There is no need for the government to regulate us to death.
