Quick answer: Yes, most plain ketchup is naturally gluten-free. But not all brands are certified gluten-free, and some contain additives that may pose a risk of cross-contamination or hidden gluten.
Does Ketchup Contain Gluten?
Traditional ketchup is made from:
- Tomatoes
- Vinegar
- Sugar or sweeteners
- Salt
- Spices and natural flavors
None of these core ingredients contain gluten. However, issues arise with added flavorings, thickeners, and processing methods, which can introduce gluten into the product.
Is Ketchup Safe for People with Celiac Disease?
Yes—if it’s certified gluten-free or labeled gluten-free. For people with celiac disease, even small traces of gluten can trigger symptoms, so it’s important to check for:
- A “Gluten-Free” label (meets FDA’s <20 ppm requirement)
- No wheat, barley, or rye ingredients
- No cross-contamination risks during manufacturing
Some brands test their ketchup for gluten and label it accordingly. Others may not contain gluten ingredients but cannot guarantee a gluten-free environment.
Hidden Sources of Gluten in Ketchup
While rare, certain ketchup formulations may include:
- Malt vinegar (derived from barley)
- Natural flavors (if derived from wheat)
- Modified food starch (source may be wheat)
- Shared equipment with gluten-containing products
If you have celiac disease or high sensitivity, avoid ketchups that don’t clearly disclose their gluten-free status.

Can Ketchup Cause Symptoms in Gluten-Sensitive Individuals?
If a gluten-sensitive person reacts to ketchup, it’s often due to:
- Trace gluten contamination
- Unlabeled wheat-based additives
- Cross-contact during processing
- Sensitivity to corn syrup, vinegar, or other additives (not gluten-related)
If you experience symptoms after eating ketchup, try a certified brand like Heinz Gluten-Free or Primal Kitchen and observe whether symptoms improve.
Are Restaurant Ketchup Packets Gluten-Free?
It depends. Many fast food chains use ketchup from major brands like Heinz, which is gluten-free. However:
- Packets may not be labeled clearly
- Shared dispensers and bulk containers can lead to cross-contact
- Always ask staff or bring your own if you have celiac disease
