✔ Answers to the most common gluten and soda questions
By the end of this guide, you’ll be equipped with all the knowledge needed to enjoy fizzy drinks without gluten-related worries.
The Science of Gluten in Sodas
Why Most Sodas Are Naturally Gluten-Free
The basic formula for traditional sodas includes:
- Carbonated water
- Sweeteners (sugar or high-fructose corn syrup)
- Natural or artificial flavors
- Acidulants (like citric or phosphoric acid)
- Preservatives
- Caffeine (in some varieties)
None of these core ingredients typically contain gluten, which is why the majority of mainstream sodas are considered gluten-free by default. Gluten proteins come from wheat, barley, and rye – grains not normally used in soda production.
The Manufacturing Process Factor
Even when ingredients are gluten-free, cross-contamination can occur during:
- Shared production lines
- Flavoring preparation
- Packaging processes
Major soda manufacturers like Coca-Cola and PepsiCo have strict protocols to prevent cross-contamination, making their products generally safe for those with celiac disease.
