My son began getting diarrhoea and severe stomach pains from tomatoes and other high salicylate foods upon introduction of these foods from 6 months. My GP wasn’t concerned about my son having constant foaming revolting smelling poo for three months but I certainly was! Thank you for your wonderful website which helped us to sort out this problem. He has shown similar reactions to salicylates in foods as he has to Nurofen – stomach pain that makes him scream for hours in agony and diarrhoea within 24 hours. This was when he was quite younger and we now know better than to give it to him. – Kate, by email
