i read some research from australia saying that there was no proven link between dairy and asthma.

There are however a lot of anecdotal tales of people responding well to low/no dairy diets. it could be worth a week or two's trial to see if it makes a difference for you personally. (I tried very briefly but i love cheese - arg).

I've been having a real issue with a mucousy kind of asthma (where if i breathe out in a huff i tend to have a tail end rattly wheeze, and often cough up sticky/lumpy white phlegm, but i don't really wheeze all the time). My doctor recommended going to three puffs of seretide (purple) twice a day. it seems to be improving. so although my lungs are"feeling" the cold air and take a while to warm up i'm hoping to stay infection free this winter!! (one plan towards this for me is to try to take it a bit easier while its cold and the bugs are doing the rounds).

more bad news on boozing:

but if you are still having the odd drink might be worth checking out the sulphite content (as these preservatives, use in foods and drinks, can trigger allergic response in some people).

less negative opinion
