  • Yeah sailors had jerky, smoked meats, and dried meats and still got scurvy. Hudson Bay colony had pemmican and still had scurvy outbreaks. The problem is most of the sources you noted destroy much of the vitamin c. Pemmican is a super food for macros but sucks for micros and still needed some forage to supplement. Famously the Iroquois would use tea made from eastern white cedar to do so.

    On your glut-4 note: glut-4 is important for cellular transportation and diabetes can harm it’s use leading to oxidative stress but it’s not significant in uptake from food to serum which is the important part when we’re talking about dietary vitamin c. It’s also really incorrect to say glucose wasn’t a factor in ancient diets. The Romans marched on porridge and bread. High carb diets are a defining feature of the neolithic and beyond.


  • Drying can work to a degree if it’s cold, but it really depends on how you dry it since vitamin c is water soluble. Anything heat dried(including sun dried, which over temp and time will oxidize the vitamin C) is out and osmosis like salt drying can bring the vitamin C along with the water into the salt. Modern sauerkraut is often pasturized so that’s pretty useless for vitamin C. Finally canned preserves are canned under high heat. These industrial processes are a major reason why scurvy was so hard to treat at the beginning of the industrial revolution. Nobody could figure it out because they kept heat treating potential solutions. The British pasturized the lime juice at one point, for example.


  • Vitamin C is heat sensitive but fermentation is fine and a good reason why fermented cabbage is popular in places with cold winter. See kimchi and sauerkraut, as rice or rye alone would kill you over a long winter. Similar mechanics going on for andean freeze dried potatoes to a lesser extent. Beyond that, it’s straight up foraging for greens and berries but that only really works if you’re moving a small enough group of people to allow forage to be an option. Plenty of leafy greens from forage allowed enough vitamin c to stave off scurvy for many ancient armies and sailors(though not all). Cook notably would beat sailors who wouldn’t eat foraged greens. The other option was uncooked organ meats.


  • Activated carbon does absorb lead because it has a variety of binding sites that will bind to lead ions. The problem is, those binding sites are limited and will get quickly used up if you’re having to actually deal with any significant amount of lead and if you have other metal ions (like copper) trying to compete for binding sites the whole profile looks worse. This means if you’ve got hard water with a ton of competing ions, the filter will likely do dick for lead. So the Brita filters do do something, but if there’s an actual utility to what they do in regards to heavy metals depends on the water.








  • Pre print journalism fucking bugs me because the journalists themselves can’t actually judge if anything is worth discussing so they just look for click bait shit.

    This methodology to discover what interventions do in human environments seems particularly deranged to me though:

    We address this question using a novel method – generative social simulation – that embeds Large Language Models within Agent-Based Models to create socially rich synthetic platforms.

    LLM agents trained on social media dysfunction recreate it unfailingly. No shit. I understand they gave them personas to adopt as prompts, but prompts cannot and do not override training data. As we’ve seen multiple times over and over. LLMs fundamentally cannot maintain an identity from a prompt. They are context engines.

    Particularly concerning sf the silo claims. LLMs riffing on a theme over extended interactions because the tokens keep coming up that way is expected behavior. LLMs are fundamentally incurious and even more prone to locking into one line of text than humans as the longer conversation reinforces it.

    Determining the functionality of what the authors describe as a novel approach might be more warranted than making conclusions on it.

    I don’t really know how I feel to see charting at day cares. I guess it does solve a liability need just as much as charting in nursing homes and hospitals do. But we’re not usually even this detailed.

    Edit: detailed on this like exact diaper changes. We’re actually much much much more detailed on falls. Like holy shit the paperwork for a fall.
