Yellowish-white mayo with a thick texture is one of the most versatile spreads for some foods around the world. Usually, they’re served with sandwiches or used as the basic ingredients of salad dressings out there. Although mayo is made from simple ingredients that look healthy, you may be wondering if it’s safe to consume on a gluten-free diet?

Is Mayo Gluten-Free?

Before concluding your mayo is gluten-free or not, you need to know the basic ingredients of mayo first. Generally, mayo is a blended emulsion of egg yolk, oil, flavored vinegar, or pure vinegar and some additional ingredients like sea salt, Dijon mustard, or white pepper.

In addition, the types of oils used to make mayo can also vary like canola, grape seeds, avocados, or olive oil. These ingredients look healthy, but you can’t assume your mayo is safe to eat.

So when it comes to Gluten, it’s a protein found in wheat, rye, barley, and triticale. They act as glues that help food stick and maintain the texture of the food. When you mix flour with water, gluten protein forms sticky tissues like glue.

This glue-like property makes the dough elastic, makes the bread expand when baked, and gives it a chewy texture. Most people may not have problems when digesting gluten. But for some people, gluten can cause a variety of health problems.

In fact, there are many wheat-free mayo, rye, or barley because they’re usually made from egg yolks or whole eggs, oils, and vinegar. Eggs or oils may not cause problems for a gluten-free diet, but you should be wary of flavored vinegar as it may contain malt. It’s a barley-derived ingredient that’s not gluten-free.
