Most people don't find refined foods tasty. In blind taste tests, people vastly prefer the old McDonalds fries back when they used actual potatoes and fried them in lard. Then the American Government said it was illegal to use lard for "health reasons" and they need to use vegetable oil instead. As it turns out, vegetable oils are considerably more pro-inflammatory than lard and, as a result, are extremely unhealthy compared to lard.
> OK, but only in the sense that a car crash is a mechanical problem (there may be repairs to make).
You're making a category error. Self-stimulating activities and inflammation are orthogonal. Mechanical problems don't always cause accidents and accidents aren't always the result of mechanical problems. Similarly, not all self-stimulating activities contribute to chronic inflammation. Eating better will absolutely help decrease chronic inflammation, but smoking pot is anti-inflammatory.
