Eating as few ultra-processed foods as possible is a beneficial heuristic.

“If you said, "David, I just want something I can tell people so that when I tell them this, it has a beneficial effect." Does telling them not to eat ultrarocessed foods or to eat as few of them as possible? Defining ultrarocessed in this way help. The answer is might help a lot. Depends on how you, you know, might might vary a little bit depending on how you said it. We need more studies. We need to figure out. My guess is as with everything else, it won't last long, right?”
