Then you should have a basic understanding of food allergies?
Trying to find a suitable meal for 2 year old dd the other day.
She is allergic to wheat. Not gluten. Wheat.
Quite often, GF products are ok for her, as they are wheat free too.
But there are a couple of companies, mostly catering for coeliacs, that use modified wheat in their products. These are no good for my dd.
I understand that most people don't know the difference, or have no reason to investigate this. It's the first time I have had to deal with it myself.
But if you are the so-called allergy expert, you would know the difference? Or at least listen when the customer explains what the poor child can eat?
