A Shopper’s Guide to Canned Tuna: Top Picks and Buying Tips

Navigating the supermarket aisle for something as seemingly simple as canned tuna can be surprisingly complex. With a wall of options promising different cuts, packing liquids and pack sizes, it is easy to end up with a product that does not suit your needs. As your Joybuy Product Recommendation Officer, my role is to help you see past the marketing clutter and make a choice that works for your kitchen, your diet and your budget.

Many shoppers find themselves disappointed after a purchase. Let's look at the common pitfalls to avoid:

1. The Net Weight vs. Drained Weight Trap: You might think you are getting a bargain, but the listed net weight includes the liquid. The drained weight is the true measure of how much fish you are actually paying for. A cheaper can with a low drained weight can be poorer value than a slightly more expensive one packed with more tuna.
2. The Chunk vs. Flake Disappointment: The label says "chunks," but you open the can to find a soft, mashed texture. The distinction between tuna chunks and tuna flakes is crucial. Chunks should be firm, sizeable pieces perfect for salads, while flakes are smaller, softer and better suited for a sandwich filler. Buying the wrong type can ruin a recipe.
3. The Hidden Calories in the Packing Liquid: The choice between oil, brine and water is not just about taste. Tuna in oil can contain significantly more calories and fat than its counterparts. While it offers a richer flavour, it may not align with the goals of those seeking a lean, high protein tuna source.

Decoding the Label: Key Factors for Your Selection

To ensure you are satisfied with your purchase, focus on these three core parameters. They determine the texture, flavour, nutritional profile and overall value of your canned tuna.

1. The Cut: Steak, Chunks, or Flakes?

The texture of the tuna is defined by its cut. This is perhaps the most important factor in matching the product to your intended meal.

• Tuna Steak: This is the most premium cut, consisting of a single, solid piece of loin. It has a firm, meaty texture that holds its shape well, making it ideal for salads like a Ni?oise or for serving as the centrepiece of a light meal.
• Tuna Chunks: The most versatile and popular option. These are smaller, yet still firm, pieces of tuna. They are robust enough for pasta bakes and salads but can also be easily broken down for use in tuna for sandwiches.
• Tuna Flakes: These are much smaller, softer pieces that have been pre-flaked. While not ideal for dishes requiring a firm texture, they are perfect for creating smooth sandwich fillings, dips or fishcakes with minimal effort.

2. The Packing Liquid: Spring Water, Brine, or Oil?

The liquid the tuna is packed in affects its flavour, texture and nutritional content.

• Tuna in Spring Water: This is the choice for those who want the purest tuna flavour and the lowest calorie and fat content. It keeps the fish moist without altering its natural taste, making it a favourite among health-conscious consumers and fitness enthusiasts.
• Tuna in Brine: A salt-water solution that seasons the fish and acts as a preservative. Tuna in brine is also low in fat but has a higher sodium content than tuna in water. It is a good middle-ground option for flavour and health.
• Tuna in Oil: Typically packed in sunflower or olive oil, this option results in a richer flavour and a more tender, moist texture. The oil adds fat and calories, but it also helps retain some of the tuna's natural omega-3 fatty acids. Remember to account for the added calories if you are monitoring your intake.

3. The Format: Standard Can, Multipack, or No Drain?

Finally, consider convenience and value.

• Multipack Tuna: For families or anyone who uses tuna regularly, buying a multipack tuna offers significant savings per can. It is a practical way to stock the store cupboard.
• No Drain Tuna: Available in cans or pouches, no drain tuna contains very little excess liquid. This format offers maximum convenience, less mess and ensures the weight you buy is almost entirely fish.

Frequently Asked Questions

Which is healthier: canned tuna in oil, brine or spring water?

For the lowest calorie and fat option, tuna in spring water is the clear choice. Tuna in brine is also low in fat but contains more sodium, which may be a concern for those monitoring their salt intake. Tuna in oil has the highest calorie and fat content, but some of the oil can be drained away. The oil can also help preserve the tuna's natural omega-3 fatty acids better than water. The choice depends on your personal dietary goals.

How long can you keep canned tuna after opening?

Once a can of tuna is opened, any unused portion should be transferred to a non-metallic, airtight container. It should then be stored in the refrigerator and consumed within two days to ensure it remains fresh and safe to eat.

What is the difference between tuna chunks and tuna flakes?

The main difference is texture and piece size. Tuna chunks are larger, firmer pieces of fish that hold their shape well in salads and pasta dishes. Tuna flakes consist of smaller, softer pieces that are easily mashed and mixed, making them ideal for smooth sandwich fillings, dips and spreads.
