There's widespread Vitamin D deficiency in the US that we should be taking much more seriously. From a 2022 review: "[Vitamin D] supplementation was associated with a significant lower risk of both Covid-19 severe disease and mortality". https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0268396 https://journals.plos.org/plosone/article?id=10.1371/journal...

I don't understand. Europe is pretty much the same latitudes, but people lived there for millennias.

  Maybe Europeans, on average, walk around more? In my experience, much of the North America is far too sprawled out to make walking viable for a vast majority of people.

  Most people worked outside in the fields for half the year and/or died in their 20s and 30s.

  Common misconception. In fact, the population barycenter of the US is further south than Athens, Greece, and lies about halfway between the Strait of Gibraltar and Lisbon, Portugal.

    Even more then.

  Possibly better food supply? They're also lighter skinned on average than the US. Your skin color makes a difference in absorption. Native European's skin evolved lighter for a reason, and that was to absorb more of the sun's benefits in a cloudier climate. The opposite is true for dark-skinned individuals; they do better in sunnier hot climates because their skin protects them from over-exposure.

  No? Madrid is about the same latitude as NYC. Paris is significally to the north of Montreal. London is about the same latitude as Calgary.

    Even more then. They should suffer from Vitamin D deficiency way more then, but we've been living there for tens of thousands of years.

Prevalence rates of severe vitamin D deficiency, defined as 25(OH)D <30 nmol/L (or 12 ng/ml), of 5.9% (US), 7.4% (Canada), and 13% (Europe) have been reported. https://www.nature.com/articles/s41430-020-0558-y https://www.nature.com/articles/s41430-020-0558-y Three-quarters of U.S. teens and adults are deficient in vitamin D, the so-called "sunshine vitamin" whose deficits are increasingly blamed for everything from cancer and heart disease to diabetes, according to new research. https://www.scientificamerican.com/article/vitamin-d-deficiency-united-states/ https://www.scientificamerican.com/article/vitamin-d-deficie... Okay, so the numbers aren't consistent. They're not even close. That and a lot of anecdotal evidence. I find it hard to take Vitamin D deficiency seriously. I am anecdotally not depressed about it.

  Maybe I'm misunderstanding your comment? You're comparing Vitamin D deficiency (< 50 nmol/L or 20 ng/ml) with severe Vitamin D deficiency (<30 nmol/L or 12 ng/ml) and saying the numbers aren't consistent?
