I interpret this to mean that most of their thoughts are about eating junk because that's how junk food works. I appreciate the glimmer of how these are emotionally driven decisions.

If all one's emotional handling is dependent on this dangerous method, it would be bad enough. Without adding the fake food onto it.

Lately, some articles have the caveat "this is only a mouse model" which they used to not even say in the capsule version for the public. I don't pay any attention because a grain eating animal is probably not a good food model for ME.

Calianna rightly pointed out the emotions involved shaped the brain. The brain reward from junk grows the appetite center because if we are eating food that is poor in nutrients, we must eat more of this low quality food.

A "malnutrition model" makes much more sense, because if we meet hunger with the Frankenfoods, that only increases our body's alarms. And now the organ we do our thinking with doesn't have the right stuff to do any thinking with.
