βKey Takeaways
You finally found a restaurant with a dedicated gluten-free fryer. Your safe French fries arrive. You grab the bottle of ketchup on the table and squirt it over your meal.
Did you just gluten yourself?
The short answer is: Most commercial ketchup is naturally gluten-free, but the bottle on a restaurant table might not be safe. Here is everything celiacs need to know about ketchup.
Is Ketchup Made with Wheat?
No. The standard ingredients for ketchup are:
* Tomato concentrate
* Distilled vinegar
* High fructose corn syrup (or sugar)
* Salt
* Spices / Onion powder
None of these ingredients inherently contain gluten. The vinegar used in American ketchup is almost always distilled white vinegar (which is GF, even if originally sourced from wheat, due to the distillation process).

The Hidden Danger: Restaurant Ketchup Bottles
If ketchup is naturally gluten-free, why do celiacs get sick from eating it at restaurants?
The danger is Cross-Contamination via "Double Dipping" and Bottle Touching.
Picture this: The customer before you at the diner is eating a massive wheat-bun hamburger and onion rings.
The "Dip" Danger: Even worse is when restaurants serve ketchup in a small communal ramekin or pump station. If someone dips their wheat-battered onion ring into the communal ketchup pump area, it's contaminated.
The Celiac Restaurant Strategy for Ketchup:
* Ask for packets: Always ask the server for sealed, single-serve ketchup packets instead of using the table bottle.
* Use wipes: If packets aren't available, wipe down the outside of the table bottle with a wet wipe before touching it, and wash your hands before eating.
* Scan specialty ketchups: If a trendy restaurant boasts a "house-made artisan ketchup," be extremely careful. They may use malt vinegar, soy sauce, or beer in the recipe. Scan it with the Check Gluten web app if it's bottled, or ask the chef directly.
Is Ketchup Safe in the UK & Australia?
* UK: Heinz ketchup in the UK uses "spirit vinegar" and is considered gluten-free. However, beware of generic chip shop ketchups, which occasionally use malt vinegar. Always check.
* Australia: Heinz and most major brands are GF, but always read the label to ensure malt vinegar isn't used as a cheap alternative.
Bottom Line: Buy Heinz for your fridge, but demand packets at the restaurant.

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.
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
