So all this talk lately about vitamin A and D, diet, too much of A, etc, got me thinking.
Now, I have done a cursory overview of the literature on vitamin D, and have not found much, so if anyone has studies either backing up or refuting this theory I would appreciate it.
So this Grant guy goes on a low vitamin A diet and does super well for maybe not those reasons. Many people have pointed out his probable low vitamin D status. Not only that, the claims that high vitamin A causing autoimmune could be flipped and said that autoimmune is caused by low vitamin D. I know type 1 diabetes occurs more in northern climates like Finland, somewhat supporting this through correlation.
Now, my theory goes like this. Our body regulates the amount of vitamin D we intake. This is why you cannot get hypercalcemia by sitting out in the sun. In fact our body seems to work hard to NOT get too much vitamin D(tanning).
What if staring at computer screens tells our body that it is at risk of getting too much vitamin D, and to lower the absorption. You can see that their spectrum of light is entirely different.
Vitamin D abosrption spectrum:
Computer screen spectrum:
What I would need to find, which I have been looking for, is some kind of connection of vitamin D absorption and light exposure from the eye. If this theory were true, going to the movies would be the worst thing for your vitamin D levels, while laying out in the sun with your eyes in total darkness would be the best thing.
My personal experience backs this up in some ways. I remember trying out haidut's vitamin A years ago and it made me feel a lot like I do if I stare at a computer screen all day. Kind of this shakey, burnt out feeling all over my body.
This would also explain ALOT of anecdotal observations.
Thoughts?
