huh? I said nothing of the sort. They're hunches.

Like: for example, it seems fairly obvious that some societal-level change happened around the 70s or 80s that triggered our modern obesity epidemics. My personal best guess is that it was the rise of processed foods messing up people's gut bacteria, but I have no actual idea. Nonetheless: you can spend as much time and energy (as a society) as you want curing obesity, but if ultimately the cause is in our food quality, then the "right" fix is obviously to fix that. The same claim applies to skin cancer and dietary connections: if the Mediterranean diet or general food quality is responsible for lower incidence of cancers in those places, then ... food quality should be fixed, right? (and sun exposure, of course, is another variable that you can just do things about).

You don't have to be an expert to think that has some validity. It's obvious. I am just quoting the expert theories, anyway.

The point really is: interventions like 'change the quality of food in America' are not things doctors can, like, prescribe to people. But they are things we can aspire to do. They will just take social movements instead of medical treatments to pull off.
