Invention studies using high dose vitamin K2 show about half of what you're describing with simply sunlight. I know I've also seen a study (I don't collect nutrition studies like I collect research for my work!) that showed a significant gap... (more)

Now that winter is almost upon us ... Is getting sun exposure through glass (e.g. sitting by a window in my warm home) as beneficial as sitting outdoors in the sun? I know that in winter the sun is low, so I'm not getting *that* much... (more)

According to this lady http://www.ancestralizeme.com/2011/11/27/paleo-hacks-keratosis-pillaris/ Vitamin D can lower Vitamin A? So say I was already a bit deficient, being in the sun without getting enough would make it so much worse? I am really... (more)

Liver. Don't rely on carrots for your vitamin A. Beta carotene might protect against the worst forms of vitamin A deficiency, but it doesn't help clear up KP if you are prone (though KP is likely multifaceted in cause, I don't think mine responds... (more)

Hi everyone, What is your take on sunscreen? Is it harmful? Is it necessary? If you use it, which brand do you use? What SPF? How often do you reapply? If you go without it, what do you use in place? Coconut oil? Hats and long sleeves? Stay... (more)

I spend the first 15-25 minutes without Sunscreen (except for face, plus a hat), to maximize vitamin D. Then I either cover up or apply a 15 SPF. I'm pale so I don't need long unprotected for D, and will burn to a crisp with any extended exposure ... (more)

Is sun exposure good for anything other than vitamin D?

Is the impact of "cheat meals" lower on sunny days (assuming you get some sunlight)? Had some nasty meals (gluten, [hydrogenated] vegetable oils, loads of sugar, soy, etc...) over the past two days and surprisingly I don't feel like crap nor am I... (more)

I think it's pretty hard to draw any definitive line between the sun and feeling better after cheats. I'd bet it's the carbs. I still get an endorphin rush when I eat more carbs than I'm used to, like an addict going back to a drug.
