I have been diagnosed with celiac disease by blood test and biopsy.
The two reasons would be Celiac disease, or pseudoscience. Since there is no reason that someone with Celiac couldn’t also be lactose, nut and legume intolerant, it could be that.
I assumed thay given they called our lactose nut and legume allergies that if they were celiac,they would have mentioned.
I was just being unclear, sorry.
Lactose intolerance isn't an allergy. It's lack of an enzyme, so microorganisms end up breaking down the sugar, leading to the gas and other symptoms.
