βKey Takeaways
You're making a turkey sandwich with your expensive gluten-free bread. You reach into the fridge for the mayonnaise. Is it safe?
The great news is that traditional mayonnaise is naturally gluten-free. However, the moment you step outside of "traditional" mayoβinto low-fat versions, flavored aiolis, or restaurant kitchensβthe risk skyrockets.
Here is the complete celiac guide to mayonnaise.
What is Mayonnaise Made Of?
Real mayonnaise is incredibly simple. It is an emulsion of:
None of these base ingredients contain gluten. The vinegar used in commercial mayo is almost always distilled white vinegar or apple cider vinegar, both of which are gluten-free.

The Danger Zones: When Mayo is NOT Safe
While traditional mayo is safe, here is where celiacs get glutened:
1. "Light" or "Fat-Free" Mayonnaise
When food manufacturers remove the fat (oil and egg yolks) from mayo, they lose the thick, creamy texture. To fix this, they add thickeners.
The Risk: Sometimes, these thickeners are modified food starches derived from wheat. Always read the label on "Light" or "Fat-Free" mayo. If it doesn't explicitly say "Gluten-Free," do not buy it.
2. Flavored Mayonnaise (Aioli, Sriracha Mayo)
Pre-packaged flavored mayos introduce new ingredients. For example, a "teriyaki mayo" or some "spicy sriracha mayos" might contain soy sauce (wheat). Always scan flavored mayos with the Check Gluten web app.
3. The "Double-Dip" Kitchen Knife (Cross-Contamination)
This is the most common way celiacs get sick from mayo at home.
* Someone makes a sandwich with wheat bread.
* They dip the knife into the mayo jar.
* They spread it on their wheat bread.
* They dip the knife BACK into the mayo jar.
The jar is now permanently contaminated with wheat crumbs.
The Fix: Buy squeeze bottles of mayo for shared households, or maintain a dedicated "GF Only" jar.
4. Restaurant Mayonnaise
When eating out, plain mayo is usually safe. The danger comes from the prep area. The person making your GF burger is likely using a shared knife or spatula to spread mayo on both wheat buns and GF buns.
The Fix: Ask for mayo in sealed packets, or ask the kitchen to use a fresh knife from a fresh container.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten β a protein found in wheat, barley, and rye β triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces β such as shared cutting boards, toasters, fryers, or utensils β rendering otherwise safe food dangerous for people with celiac disease.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten β stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
