What is gluten?
Gluten is a protein found in most wheat products, and acts as the “glue” that helps to hold wheat, barley, kamut, spelt, farro, durum, bulgur, rye, and semolina together to maintain their shape.
You can find gluten in whole grains, but also in many processed foods as well. If you purchase wheat bread, there will be gluten in it, because wheat by nature has gluten.
Many processed foods have hidden gluten in them in the form of gluten or wheat derivatives. These are also in the form of flavorings, binders to keep ingredients together, or other additives.
Is oat flour gluten-free?
Oat flour may or may not be gluten-free, depending on the oats that are used to create the flour.

Many oats are processed in the same facilities and on the same equipment as wheat and other gluten-containing grains.
If you follow a gluten-free diet, you will want to be sure that any oat flour you purchase has a gluten-free label, otherwise anticipate there is a risk of gluten cross contamination within that product.
