On a random but tangential subject to the elevit... I once saw a very convincing presentation on the rise of asthma, but this is a UK thing. You can track new homes and asthma increases really well. What basically happened is that we used to have cold, dry, draughty homes with rubbish windows. Now we have proper windows and blocked up chimneys and better heating and had warm damp houses as they aren't circulating air anymore, and this causes the massive rise in childhood asthma apparently. Not sure how that applies to Australia, but I suspect re-circulating air con is a culprit too.

I too am still taking elevit, but more for the vitamins than the folic acid. Being veg, thought I'd better cover my bases!
