According to new research in the Archives of Internal Medicine suggests that low levels of vitamin D are 'linked' to colds.

According to WebMD:

"The results showed those with the lowest vitamin D levels (less than 10 nanograms per milliliter of blood) were 36% more likely to report having a recent upper respiratory tract infection than those with higher levels (30 ng/mL or higher)." The data was gathered from 19,000 people enrolled on the NHANES III trial.

I can't find the original research yet on the AIM site, but i'll be interested to read it. I would imagine the sales of vitamin D tablets will sore [throat]!

Thanks! I try not to be too cynical of these discoveries, but I think I'm a bit of a grumpy old man really. I'll check out the Bad Science book - I do like his column.
