I was watching a show about the human body on tv last night and there was one segment on asthma. Now they were talking about the extremely high rate of asthma in children in 'developed countries'. That's the term they used.

Now I'm wondering whether that is caused by the types of foods we eat and general diet which include foods which are not good for us generally but also foods to which we too often become allergic. Does it mean that the children in the "undeveloped" countries don't have asthma for that reason or what?

There's also been a lot in our news in Australia this past week about our trend towards over cleanliness and how that's actually seriously impacting the health of our children.

Any thoughts from you all about this trend regarding cleanliness and the asthma rates in some of our nations? Are the two connected and what else is there in the mix (like immunisations or other things) to make our rate of asthma so high.

thanks...
