Test Shows Junk Food’s Alarming Impact on Human Cognition

So this is why I’m dumb.

The article doesn't mention anything about testing the same people over a period of time. So, is the junk food reducing people's cognition, or is it simply more likely to be eaten by people who already have low cognition?

When I do keto there's a striking change in clarity. Most people I talk to that also do keto experience the same thing.

When I'm driving, I notice dents and cars and abnormalities in road lines that I normally would just filter out and ignore.

If I jump back in and eat a bunch of carbs it goes away pretty quickly. It's not to say that I can't see the things if I were looking for them but it's like my brain just goes yeah whatever.

I wonder If they tried controls on overeating versus under eating instead of just healthy versus unhealthy.

While the result fits my priors, I don't think the study is worth much, since it relies on self-reported diet, and relies on WEIRD test subjects.

Maybe they should have put the hamburger and fries in the chest.
