Is Diet Dr Pepper Gluten-Free? Your Comprehensive Guide
If you’re wondering whether Diet Dr Pepper is gluten-free, the answer is a definitive yes! This popular soft drink is free from any gluten-containing ingredients and is safe for individuals with gluten sensitivities.
The Ingredient Breakdown
To determine if Diet Dr Pepper is gluten-free, we need to analyze its ingredients: carbonated water, caramel color, aspartame, phosphoric acid, natural and artificial flavors, sodium benzoate (preservative), and caffeine. None of these ingredients contain gluten.
Carbonated water is simply water infused with carbon dioxide; it’s gluten-free by nature. Caramel color may sometimes raise eyebrows, but it is derived from sugar and does not contain gluten unless it’s mixed with wheat-based products, which is not the case here. Aspartame, a low-calorie sweetener, is also gluten-free and has no connection to gluten production.
Phosphoric acid is a mineral acid and is generally regarded as gluten-free. Next comes natural and artificial flavors – these can be derived from various sources but are typically gluten-free unless specified otherwise. Lastly, sodium benzoate is used as a preservative and is considered safe for gluten-sensitive individuals.
