Is Chunk Light Tuna in Water Gluten Free?

The Ingredient Breakdown

When evaluating any processed food for gluten, we must look beyond the main protein source and inspect the flavor enhancers. For Chunk Light Tuna in Water, the ingredient list is remarkably short, which works in its favor for gluten-free certification.

The primary ingredient is SKIPJACK TUNA (KATSUWONUS PELAMIS). As a fresh fish, tuna is naturally gluten-free. There is no risk of gluten inherent to the fish itself. The second ingredient is simply WATER, which acts as the packing medium and introduces no allergens or gluten.

The potential risk in canned fish usually lies in the flavoring agents. Here, the product uses VEGETABLE BROTH and SALT. Vegetable broth is typically a blend of carrots, onions, and celery. Unlike yeast extract, which can sometimes be derived from barley (a gluten grain), vegetable broth is derived from safe, gluten-free vegetables. Finally, SALT is a mineral and is naturally gluten-free. There are no hydrolyzed wheat protein, modified food starch (unless specified as corn), or malt vinegar used in this formulation.

Nutritional Value

Chunk Light Tuna in Water is widely considered a 'clean' protein source. Because it is packed in water rather than oil, it maintains a low fat and calorie profile. A standard serving typically contains approximately 100 calories, with the vast majority coming from high-quality protein (roughly 22 grams per serving).

Regarding carbohydrates and sugar, this product is an excellent choice for low-carb diets like Keto or Paleo. It contains 0 grams of carbohydrates and 0 grams of sugar. The sodium content usually hovers around 200-300mg per serving, which is moderate.
