Even with a flawed messenger pointing the wrong tools at the wrong target, isn't "avoiding ultraprocessed foods, seed oils, pesticides, and fluoride" still fundamentally a step in the right direction, compared to previous politically-connected health campaigns, like the infamous one not so long ago to "get out and move", which placed blame on kids for being unable to out-exercise a bad diet, while doing absolutely nothing to criticize or curtail the industry that pumps carbonated water full of sugar and then deliberately markets it to impressionable, easily addicted, easily manipulated children?

All criticism levelled at the people loading obscene amounts of sugar into bread, tomato sauce, baby formula, water, and every other food under the sun is good criticism, even if it comes from a sometimes-problematic mouth.

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.

  • 1. The idea that UPFs being poorly defined == UPF is a meaningless designation has always sounded like absurd whataboutism that stops real progress to me.

    Surely you don't mean to suggest that just because UPFs aren't perfectly defined, that means there's no fundamental difference between a diet composed of skittles, donuts, and ice cream cookie sandwiches versus a diet composed of organic, plant-based whole foods, right?

    2. You say there is "no evidence" that seed oils are bad... yet when I search for "canola oil health hazards", the very first thing I see is "Canola oil has been associated with potential health hazards due to its high omega-6 fatty acid content, which may contribute to inflammation and chronic diseases when consumed in excess. Additionally, the refining process often involves chemicals like hexane, which raises concerns about the presence of harmful byproducts, although these are typically present in very low amounts in the final product."

    Am I crazy to prefer that the amount of hexane in my food be as close to absolutely none as possible? Am I crazy to not wanting to be loading myself up with something that's at least clearly associated with inflammation and chronic disease?

    3. Why do we have to assume that the optimal replacement for seed oils is lard? Is it possible to consider that maybe we'd all be better off if we stopped eating french fries, rather than merely switching what greasy junk we're frying them in?

    4. Plenty of non-organic foods have pesticides on them! https://www.ewg.org/foodnews/full-list.php

    Is EWG not a generally reliable and trustworthy source of information? Do you mean to suggest that no foods grown outside ever have any pesticides on them, or that the pesticides never follow the food all the way to the grocery store? Haven't plenty of agricultural products over the years, including Round Up, been linked with high probability to various cancers, neurodegenerative diseases, etc?

    5. Why do we assume that filtering water means taking away other healthy actions? Do we need to be giving kids MORE sugar just because it's natural (berries)? Is there not extensive scientific literature linking fluoride ingestion with decreased IQ?

    6. Why can't we have a open, good-faith conversation about these topics without engaging in tribal politics? Why do we get so emotionally attached to current narratives and beliefs about these kinds of things even when we know those beliefs are formed based on incomplete information and should be subject to change as we learn more over time, a standard exercise of basic epistemic humility?

I may have seen it here, but there's a new article out on childhood fluoride exposure: https://www.science.org/doi/10.1126/sciadv.adz0757

"Whereas most prior research has estimated effects of exposure to extremely high levels of fluoride, we consider exposure to levels of fluoride within the range typical in most places and of greatest relevance to policy debates about government water fluoridation. We use data from the nationally representative (United States) High School and Beyond cohort, characterize fluoride exposure from drinking water across adolescence, adjust for confounders, and observe cognitive test performance in both secondary school and at age ~60. We find that children exposed to recommended levels of fluoride in drinking water exhibit modestly better cognition in secondary school, an advantage that is smaller and no longer statistically significant at age ~60."

I'm very much overweight, though not morbidly obese. I have been at my best weight when I did "get out and move". The problem, of course, is that schools, jobs, and modern infrastructure don't make that as easy to do as in prior decades. You can't just tell people to do something that has been made difficult to do and expect them to do it.
