DS1 hasn't been well for a while and the GP has just diagnosed him as having coeliac disease (his blood tests levels were really high apparantly) and has referred him to the gastroenterologists for an endoscopy.

I've been researching the type of diet that he'd need to follow once he's had his endoscopy and my head is spinning!

We're on a seriously limited budget as I'm a student so I don't have any spare money to make mistakes with dodgy food - are there any brands etc that should be avoided? We've got a big freezer and I love cooking so I'm happy to batch cook. Are there any companies that I can buy in bulk from? Are supermarkets cost effective?

Thanks
