We’ve all heard the saying that breakfast is the most important meal of the day. If that’s true, then it is a good thing eggs are gluten free? Or are they? If you happen to have celiac disease or a gluten sensitivity, you may find yourself questioning the safety of foods you never gave a second thought to before.

That brings the question; do eggs have gluten? Fret not since eggs are one of the many foods that are naturally gluten free. This doesn’t imply that commercial egg products and all foods made with eggs are gluten free. You still have to be careful when shopping at the grocery store or cooking at home.

It is easy to assume that an egg is an egg, but that isn’t necessarily true. The eggs you probably know about come from chicken but you may notice that they are available in different colors and sizes. You’d be surprised to learn that eggs come in different grades as well. These include Grade AA, Grade A, and Grade B.

Grade AA have the best appearance with firm, thick whites and round yolks. They tend to have little to no visible defect. Grade A eggs are the same as AA eggs, but the whites may only be ‘reasonably firm.’ Things tend to be different Grade B eggs since it is mostly used in liquid egg products since they don’t look as presentable.

Even though you may not pay close attention to the grades of the eggs you buy at the store, you certainly factor in the size. Egg sizes range from small to jumbo and the size typically refers to the amount of the liquid the egg contains.

A jumbo egg contains about 2.5 ounces while a small egg contains about 1.5 ounces of liquid. It may not make much of a difference if you use a large egg or a small egg in a recipe, but if your dish calls multiple eggs, it might. When it comes to egg color, it mostly depends on the type of chicken. Be sure to also factor this in before buying an egg.
