Re: Re: Vitamin D Reduces Risk of Diabetes by 75%!!!!!

[Guest guest]

In the summer I use sunscreen. In the winter however when all skin is

covered and not exposed (even when you're in the sun), I don't use sunscreen

on my face (the only part exposed to the sun). The sun is much lower in the

sky and weaker during Nov, Dec, Jan, Feb.

Any comments about this???

Hi Francesca:I have serious doubts that sunshine in winter in northern latitudes, being filtered through much more of the atmosphere than in summer, even contains enough of the wavelength of light required to generate vitamin D, even if you were naked.I noted in the spring that my indoor tarragon plants, that had been in full sun all winter and been in hibernation, sprang to life as the sun got higher in the sky along with the plants outside. Since the indoor plants were still at the same temperature as they had been all winter it does seem that either the higher angle of the sun or the longer days are what causes plants to grow. Could it be a lack of important nutrients produced by leaves in insufficient quantities in reduced sunlight?This is speculation, of course. But whatever, it does seem clear that one should be ABSOLUTELY sure not to be on the low side in vitamin D intake. Of course it is toxic in high doses. I remember a discussion here with on this issue some months back. Can anyone remember what we concluded was the upper safe daily limit for vitamin D?(I VAGUELY remember it was 3000 I.U.. I believe it was suggested that you can get 10,000 a day from exposure to sunlight. But I do not want to get this statistic wrong. So, as always, caveat swallowor).This source says upper safe limit for vitamin D is 2000 IU, fwiw:http://www..net/info/vitamin_a_d.pdfRodney.
