I discovered I have coeliac recently.
I never bought bread by my own initiative, I don't like any "whole grain" product and I hate beer flavour. I think there was self knowledge in the back of my head about the gluten happening to be a problem to me.
Now, I notice my daughter doesn't like to eat any bread, baking, pies, cakes.
And my son snacks all day, yes all day he is picking food: fruits, sausages, ham, cheese, yogurt; but he doesn't take bread neither.
My husband buys bread for the family and practically he is the only one that eats it by his own initiative.
I am doing a coeliac test to my kids soon.
But the doctor told me even when coeliac can be inherited, it may not be active until later in life, so these tests can be negative and my kids can eat gluten normally now and that doesn't mean they are free of risk in a future it becomes active.
No clue how to get the genetic test, must be expensive.
