Ultra processed foods is not a well defined category, so saying avoid UPFs is meaningless.

There are several “UPFs” that have better health outcomes than NOVA 1 “unprocessed” foods, because the NOVA system was never developed to categorize foods by how healthy they were but instead how closely they matched a fairly regional Brazilian diet.

There is no evidence that “seed oils” are bad beyond their caloric density, and seed oils like Canola oil are some of the healthiest fats we have, far more than the lard they’ve been encouraging people to consume instead (which is almost certainly worse than most seed oils, except possibly rhe single scenario where a fast food chain may be heating and reheating the same fat source many times over).

No one is buying and consuming oesticides, so that’s in actionable advice for people.

There is absolutely no evidence fluoride levels in US water are anywhere near dangerous levels. Having people buy and maintain expensive filters simply to keep fluoride out of their water likely won’t help with anything, and will likely displace some other more healthful actions they could be taking, like spending the money on buying berries for their kids.
