I began the elimination diet after reading Fed Up with Asthma [now out of print, the asthma information from this book has been incorporated into the 2008 edition of Fed Up]. I was pregnant with our second child. My first pregnancy was fraught with pain from aching joints, hips especially, from which I d never suffered before. The pain was very great and continued after childbirth, though not troubling me much, just now and then. My joint movement continued to be impaired. In this pregnancy the pain began in the first trimester, whereas it had begun late in the previous pregnancy. I suffered much sleeplessness and worried how I would last 9 months like this. After 2-3 weeks on the diet (dairy and gluten-free as well) I no longer needed ventolin at all, just one puff daily of my preventer (I'd been using ventolin up to 8 times daily with little effect and 4 puffs of the preventer). Also, no joint pain at all, and the return of a normal range of joint motion. - Elizabeth, by email
