Anyway, downvotes most likely were for how strangely arguments were lined up by GP..
1. there is a large healthy range between unhealthy lack of enough sun and unhealthy sun exposure (and you can shift that with sunscreen).
2. Lack of sun has not much to do with obesity.
Saying between the lines that suncreen is unhealthy and makes you fat.. yeah I know he didn't say, but..
I think based on the studies linked in the source above quite a lot of what you've stated as plain fact is easily debatable.
1. Does not seem like Vitamin D supplementation provides any of the benefits that are linked to Vitamin D from sun exposure.
2. The maladies strongly linked to being combatted by said Vitamin D kill far, far more Americans (700,000) than melanoma (7,000) a year.
3. Obesity and vitamin D have a pretty strong experimental link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5691711/
This is a great example of why correlation does not imply causation.
Because no thanks on that. I'll keep wearing the sunscreen.
Let's not pretend it never existed just because people historically didn't know what it was or how to document it.
