I too am a member of the growing ranks of asthmatics in our country. I still take my meds, but since being paleo I've found that I can greatly decrease them...I take half the steroids I used to and I've reduced having to use a rescue inhaler by around two thirds. It takes time though. I didn't notice a big change until a couple of months of following the paleo lifestyle rigorously. Avoiding all those alien proteins I think pays off and reduces the "toxic overhead" so the body can get to work healing and rebalancing. My body lets me know in no uncertain terms when I've fallen off the wagon...the asthma comes back almost overnight with a vengance. My experience of course is purely anecdotal.
