I have a nine-and-half-year-old daughter who has a day and night time bladder problem (urinary urgency) since the age of 3. I have seen all the specialists, psychologists, and natural helpers available. By the age of 8 she was, as it seemed, growing out of it. But after reading your book, Fed up, I linked it to preservatives, flavours and colours. Coincidently I was cutting down after our son had behavioural problems, and I heard you speak around that time. I took your advice and cut out the bread preservative first and then other things, but I didn't take salicylates seriously yet, especially with our daughter because she is so thin and a fussy eater. Her bladder problem seemed to creep back when Grandma was buying strawberries for her alone, as she knows our son could not have them.

Then when her brother was doing the salicylate challenge she was indulging in all these foods too, and of course her bladder problem is so evident now. – by email.
