The Solid White Albacore: A Safe Option
Plain canned tuna can be a safe protein source for those on a gluten-free diet. Chicken of the Sea's Solid White Albacore Tuna in water or oil is generally considered gluten-free. The basic varieties contain tuna, water, salt, and often vegetable broth. While vegetable broth in water-packed tuna is regulated by the FDA and typically made from gluten-free sources, it's always best to check the label.
Chicken of the Sea states that many, but not all, of its products are gluten-free, emphasizing the need to check each product label as ingredients can change. Sticking to unflavored, basic varieties is recommended unless a clear "gluten-free" certification is present.
Understanding Vegetable Broth
In canned tuna, vegetable broth is usually derived from gluten-free vegetables. However, some broths in other products may contain gluten sources like hydrolyzed wheat protein. Relying on certified gluten-free labels or simple ingredient lists provides the most assurance.
The Gluten-Free Risks: Flavored and Enhanced Tuna
Flavored tuna products often pose a gluten risk due to added ingredients. Chicken of the Sea has identified some products that are not gluten-free because they contain ingredients like bread crumbs or crackers.
Common sources of hidden gluten in tuna products:
- Marinades and Sauces: Teriyaki sauce may contain wheat-based soy sauce.
- Meal Kits: These often include wheat-based crackers.
- Thickeners and Additives: Modified food starch can be wheat-derived, and hydrolyzed wheat protein is a gluten indicator.

Navigating Labels for Safe Choices

A Quick Note on Mercury and Tuna Selection
Albacore tuna, used in solid white varieties, generally has higher mercury levels than light tuna. The FDA advises limiting albacore consumption to about one serving (4 ounces) per week. Light tuna is a safer choice for more frequent consumption. Tuna provides protein and omega-3s, making it a nutritious option in moderation.
Conclusion: A Clear Path for Gluten-Free Tuna Lovers
To summarize, plain Chicken of the Sea solid white tuna is generally gluten-free and a nutritious option. However, flavored varieties and meal kits often contain gluten, so vigilance is necessary. Always read labels, seek gluten-free certifications, and contact the manufacturer if unsure to ensure safe consumption.
