I have been on the RPAH low salicylate diet for many years with tremendous success in controlling very severe asthma … My doctor … has been very interested and supportive of all the food intolerance information. He is quite a convert! As well as asthma, I also had very bad nasal polyps. Had two lots of very painful surgery to remove them. When I stopped using the nasal spray the specialist prescribed they went away and never came back. My GP was totally convinced!!! - Krys aged 78
