Q: Why can I NOT tolerate GF oats? The reaction I have is not as severe like when I've inadvertently gotten into gluten in the past but I still react w/mild GI symptoms. Mainly gas and bloating. I REALLY miss eating oats and they are not considered an allergen so I have to check the ingredients even when it's labeled gluten free.
There can be several reasons for your GI symptoms with oats. A small number of celiac patients react to the protein called avenin in oats. Another issue can be the high levels of soluble fiber in oats. Soluble fiber can cause gas and bloating in some individuals depending on the amount they are consuming.
However, one of the biggest issues with oats is that a lot of sources of oats have had cross-contact with gluten-containing grains - even some that are labeled gluten-free.

Always discuss with your doctor or dietitian before introducing gluten-free oats into your diet.
