Last night I made a beef casserole which I now realise was probably very high in salicylates. There were no additives but I used a base of one tablespoon of tomato paste and about a tablespoon of fresh herbs from my garden and about 100mls of red wine, cornflour and just carrots and celery with gravy beef. Of this casserole my son would have had about two tablespoons (with some basmati rice). I wasn't sure if this quantity would be is sufficient to cause a behavioural reaction but within about one hour my food sensitive son was headbutting my husband and just couldn't calm down. My youngest son who ate the same quantity had zero reaction. – Courtney, by email
