For those who may not be aware, there are many people who have wheat allergies (gluten allergy) with the most severe cases being those with Celiac Disease.
As someone with a severe wheat allergy and eating gluten can and has put me in the hospital.
A gluten free diet does tend to me much more of a bland diet but luckily many restaurants offer gluten free foods. Even Olive Garden has a gluten free menu.....
It's more common than people think but some only have mild symptoms. If you have acid reflux, dysphagia (difficulty swallowing), or chronic cough ask your doctor to get an allergy panel.
