Nothing is killing off fast food except actual knowledge of what it does to people. And the reason they emphasize carbs is that it's cheap as dirt and endlessly maleable.

If grains were all mueslix/granola it would be different. Instead, it can be made into a myriad of things, from shape to texture, that hits the brain like a runaway train.

We have never been good at avoiding THAT. People still in the hunter-gatherer stage brew intoxicating beverages. With pre-fire techniques.

We can't eradicate that effect. We can stop the lies that call it "harmless." When people are more aware of harm, they do shift their behavior.

Remember when Atkins became so popular the cereal and donut people were worried? They attacked Atkins, but then co-opted keto... and made it not-keto with their additives and green drinks and I don't know how many MLM products.

Get them out of science. Or this won't stop. Everything just becomes PRODUCT to them, with no nutritional value.

Like the movies, lately. Fortunately, those are all flopping. If junk food is as bad as smoking, we can say so and do something.
