Hi all, a while back i paid for a health download from an American nutritionist and now get bombarded with newsletters and sales pitches from various U.S. health practitioners. Besides trying to sell me stuff, they also send out useful info now and again and I just got one about Vit A and thought i'd post it, since we've had so much about the (supposed?) benefits of Vit A posted onto the site before.
Hope the link works but copy and paste if not.
Basically its a warning against taking too much since there's been new (I think) research that, unlike Vit D, Vitamin A can compromise your immune system. There is a link in the article to the National Institutes for Health which gives correct daily amount to take but advises to get as much as possible from your food. Don't know though whether as many of us are older folks we may have difficulty absorbing it from food.
