What Types of Tuna Fish Are There?

There are several species of tuna fish consumed around the world. The most common ones are:

• Albacore (white tuna) This is usually sold as canned white tuna It has a milder flavor and lighter color

• Yellowfin: Known for its signature steak-like texture. Often used for tuna steaks and sushi.

• Bigeye: Similar to yellowfin but tends to be oilier with a stronger flavor. Used for sashimi and sushi.

• Bluefin: The most prized and expensive tuna. Ideal for sashimi and high-end sushi. At risk of being overfished.

• Skipjack: Smaller tuna often sold as “chunk light” canned tuna. It has a stronger taste than albacore. Good for tuna salads or casseroles.

So those are the main types you’ll encounter. Now let’s look at potential sources of gluten during processing and manufacturing.

Tuna Processing: Where Could Gluten Come From?

Tuna fish on its own does not naturally contain any gluten. However, tuna undergoes processing and preparation before it reaches our plates. Here are potential sources of gluten during tuna processing:

• Breading or batter: Tuna steaks are sometimes breaded or battered before cooking. The breading/batter typically contains wheat flour.

• Flavoring powders: Spice blends added to canned tuna often contain anti-caking agents that could be sources of hidden gluten.

• **Broths and sauces:**Many canned tuna products contain vegetable broths, soy sauce, or other flavorful liquids that may be thickened with wheat starch.

• Mayonnaise: Added mayo in tuna salad kits could contain gluten depending on the brand.

• Cross-contamination: Tuna processing facilities also handle other gluten-containing ingredients and foods. Shared equipment could lead to cross-contact.

So while tuna itself is naturally gluten free, processing factors must be considered. Let’s look at some specific brands and products next.

What About Tuna Packets, Cans with Flavors, Tuna Salad Kits?

While basic canned and pouch tuna tend to be gluten free, exercise more caution with these varieties:

• Flavored tuna packets: These often contain soy sauce, which could have wheat. Check for gluten containing ingredients.

• Tuna cans with flavor: Lemon pepper, herb, spicy chili – these often have added broths or starch thickeners. Verify gluten free status.

• Tuna salad kits: Pre-made tuna salads could contain gluten sources like wheat-thickened mayonnaise or croutons. Check ingredients.

• Tuna lunch kits: If these contain crackers, bread, or pasta salad, verify these are made gluten free.

• Tuna patties or cakes: Binders and fillers like breadcrumbs or wheat flour are commonly used. Ensure gluten free.

In general, the more flavored and pre-mixed a tuna product is, the higher the likelihood of gluten. Plain canned tuna tends to be simplest and safest.

What About Eating Tuna at Restaurants?

Dining out with celiac disease or gluten sensitivity always involves some degree of risk. Here are some tips for eating tuna safely at restaurants:

• For tuna sashimi at a sushi restaurant, this should be naturally gluten free. But verify no soy sauce or other gluten sources were used in preparing the fish.

• Tuna steak entrees could be marinated or basted in a gluten containing sauce. Ask for plain grilled or baked tuna.

• A tuna melt sandwich is likely to have glutenous bread and could be contaminated during preparation and grilling. Best avoided.

• Tuna salad appetizers or side salads may have croutons or thickened mayonnaise. Ask for no crackers/croutons and verify gluten free status of mayo or dressing.

• Tuna casseroles or tuna noodle dishes at restaurants are high risk due to potential wheat-based noodles, bread crumb toppings, etc. Steer clear.

When dining out, stick to basic grilled, steamed, or pan-fried tuna fillets or steaks. Avoid complicated tuna dishes with lots of ingredients or garnishes. And always advise your server of your gluten free dietary needs.

Safe Gluten Free Alternatives If You Need to Avoid Tuna

Some people avoid tuna fish for reasons other than gluten, like high mercury levels or sustainability concerns. Here are some safe gluten free alternatives:

• Canned salmon, sardines, or mackerel
• Smoked salmon slices
• Canned chicken or pork
• Shrimp, crab, or lobster salad
• Chickpea salad
• Egg salad
• Roasted veggie salad or slaw

These all make excellent replacements in sandwiches, salads, snacks, or recipes calling for tuna as the protein element.

You can also substitute other gluten free whole food proteins like chicken, turkey, ham, roast beef, hummus, beans, Greek yogurt, etc. Lots of options to stay gluten free without tuna!

The Verdict: Most Tuna Fish Is Gluten Free

After reviewing the major tuna brands, processing factors, and considerations – tuna fish is generally considered gluten free, with a few caveats.

The key is to stick with plain solid canned white albacore or chunk light tuna packs with minimal added ingredients beyond salt and water. And of course, always verify by carefully reading the label and contacting manufacturers with any questions.

While restaurants and pre-flavored or pre-mixed tuna products add more risk, overall tuna fish is a safe, healthy gluten free protein option that can be enjoyed in moderation as part of a balanced diet.
