Perhaps not helping a child learn? Not providing good moral guidance? Perhaps even letting a television or video game be the parent?
It is not processed sugars or corn syrups, or some genetically modified potato starch that lowers IQ, it is the lack of homelife that lets a child turn off their mind, rather than stretching it to see the limitless horizons that are out there.
Precisely! If the parents aren't interested enough to occasionally feed their children something other than junk and fast food, they are probably also not interested enough to read to the children, play with them, make sure that they have toys that encourage the use of imagination, etc.
It's also quite likely that the parents may not be the sharpest tools in the shed themselves and that they have passed that along to their children.
This "study" seems very poorly designed and pretty much useless.
This study brought to you by the letters Huge and Ass
It's extremely well designed for what it is, a piece of political propaganda. Fat kids didn't do it, poor health didn't do it, now they're trying to demonize 'fast food' by saying your kids will be stupid.
Honestly, I've always had a hard time trying to figure out who they're propping up with these studies. Global warming frauds are easy: corn, solar, other scammers. I have to assume that these studies are being funded by more 'nutritious' junk food, the 'healthy alternatives' that address none of the core issues.
Or, well, it could just be normal liberal wastes of time, making people feel guilty without offering the slightest bit of a solution, which is far more likely than any conspiracy.
