Canned tuna is a pantry staple for many. It’s affordable, high in protein, and easy to use. But not all canned tuna is what it claims to be. Some brands use inferior fish, fillers, or processing methods that reduce nutritional value. Others may even contain species that aren’t true tuna. Here’s how to spot the difference.
What “Real Fish” Really Means
“Real fish” in the context of canned tuna means pure, unadulterated tuna muscle meat from a recognized species, packed in its own juices or healthy oils, without fillers, broths, or soy protein. Many cheaper brands cut corners.
7 Types of Canned Tuna to Think Twice About
1. Tuna Packed in Vegetable Broth
Some brands use broth to add weight and reduce cost. This dilutes the natural flavor and nutrients. Real tuna should list only tuna, water or oil, and salt.
2. “Chunk Light” Tuna with No Species Listed
If the label simply says “tuna” without specifying skipjack, albacore, or yellowfin, it’s likely a mix of lower-quality fish. Transparency matters.
3. Tuna Packed in Soybean or Cottonseed Oil
These oils are cheap and inflammatory. They mask the natural flavor of the fish and add unhealthy fats. Choose olive oil or water-packed options instead.
4. Pre-Flavored Tuna Packets with Added Sugars
Flavored tuna often contains sugar, modified starch, and artificial flavors. These are highly processed and less healthy than plain tuna.
5. Very Cheap Store Brands with Vague Labeling
Extremely low-priced tuna may contain more dark meat, which is less flavorful and has fewer omega-3s. Some may also include fillers like soy protein.
6. Tuna from Unregulated or Unsustainable Fisheries
Without sustainability certifications like MSC (Marine Stewardship Council) or Dolphin Safe labels, you can’t be sure of the fishing practices or the quality of the fish.
7. Imported Tuna from Countries with Low Safety Standards
Some imported tuna may contain higher levels of mercury or contaminants. Stick to brands that are transparent about their sourcing and testing.
The 2 Types of Canned Tuna That Are Actually Real Fish and Worth Buying
1. Wild-Caught Albacore Tuna (Pole-and-Line Caught)
Albacore is higher in omega-3s and has a milder, cleaner flavor. Look for pole-and-line caught albacore packed in olive oil or water. It’s more expensive but worth it for the quality.
2. Wild-Caught Skipjack Tuna (MSC Certified)
Skipjack is a good option if it’s sustainably sourced. Look for the MSC blue label and choose tuna packed in olive oil or water. Avoid brands with added fillers.
How to Read the Label Like a Pro
- Look for the species name: Albacore, skipjack, or yellowfin.
- Check the ingredients: Should list only tuna, water or oil, and salt.
- Choose the packing liquid: Olive oil or water. Avoid soybean or vegetable oil.
- Look for certifications: MSC, Dolphin Safe, or non-GMO.
A Gentle Reminder
You don’t need to spend a fortune, but a little attention to labels can make a big difference in the quality and nutrition of your canned tuna. Your body deserves real fish — not fillers. Choose wisely, and enjoy the benefits of this humble, healthy pantry staple.
