Hidden Sources of Gluten

Hidden gluten sources are everywhere and unless you're aware of these gluten containing items, whether their food or other types of things we are in contact with daily, you'll be leaving yourself open to lots of potential gluten symptoms without knowing where you've picked the gluten up from. I've made a point of seeking out some of these gluten sources because it seemed that I would many times find myself experiencing gluten symptoms without knowing why. I hadn't eaten anything that would cause it, and was bewildered so here's some of the gluten sources I found out about over the years and try to avoid.

Vegetable Protein and Food Starch

Vegetable protein and food starch seem like o.k. ingredients for those of us with celiac or gluten intolerance right? Wrong. Those are actually hidden sources of gluten with those seemingly harmless names on it. If you find those two names on a food label, avoid it to prevent any potential gluten reactions. These are the types of ingredients that the gluten communities are putting pressure on the FDA with for more reliable and strict labeling laws. Until then, those of us that need to be gluten free should be aware of what these ingredients really are.

Toasters

Also be aware that your toaster is a hidden gluten source too. If you're toasting your bread in a toaster that others are toasting gluten breads in, you'll be open to a lot of gluten that you didn't realize was there. Avoid that situation by purchasing a exclusively gluten free toaster for anyone in the house that has gluten intolerance issues.

Baking

I was surprised to find out that wheat flour dust particles can stay in the air for up to 24 hours after it's used. That being the case when the holidays roll around, and you need to make gluten baked goods as well as gluten free baked goods be sure to bake the gluten free batches first. In this way when you bake with gluten you'll be able to avoid the dust for some time after baking.

Double-dipping

Be aware of peanut butter or jelly and other types of food items in jars that are spread on gluten bread and then double dipped back into that same jar of food after the knife being used has spread the jam, peanut butter other food onto that gluten containing bread. It's best to purchase your own foods that are packaged in jars for this reason.
