Sardines are one of the most nutrient-dense foods you can eat. They are packed with omega-3 fatty acids, calcium, vitamin D, and high-quality protein. But not all canned sardines are created equal. Some are packed in low-quality oils, others are overly processed, and some simply lack the flavor and texture that make sardines a pleasure to eat. Here are the types of sardines to avoid and what to look for instead.
7 Canned Sardines to Avoid
1. Sardines Packed in Soybean or Cottonseed Oil
These oils are cheap and inflammatory. They mask the natural flavor of the fish and add unhealthy fats without any benefit. The oil itself may also be highly processed.
2. Sardines with Added Preservatives or Artificial Flavors
Some brands add preservatives or flavorings to extend shelf life or mask lower quality fish. The best sardines need nothing added.
3. Sardines from Unsustainable Sources
Overfishing is a concern. If the label does not carry a sustainability certification like MSC (Marine Stewardship Council), the fish may have been caught using methods that harm the ocean ecosystem.
4. Sardines with High Sodium Content
Some brands pack sardines in heavy brine or add excessive salt. Too much sodium can be a concern for those watching their blood pressure.
5. Sardines from Unknown or Vague Origins
If the label does not specify where the fish were caught, you cannot be sure of the quality or freshness. Transparency is a sign of a trustworthy brand.
6. Sardines in Poor-Quality, Rusted, or Damaged Cans
Inspect the can before buying. Rust, dents, or damage may indicate the contents have been compromised or the fish is past its prime.
7. Sardines That Smell or Taste Overly Fishy or Rancid
While sardines have a distinct fishy flavor, high-quality sardines should taste clean and fresh. If they smell overly fishy, rancid, or like ammonia, they are not fresh.
3 Canned Sardines That Are ACTUALLY Great
1. Sardines Packed in Olive Oil
Olive oil is a high-quality, heart-healthy oil that complements the flavor of the fish. Look for extra virgin olive oil when possible. The oil can also be used in salad dressings or drizzled over vegetables.
2. Wild-Caught Sardines with Sustainability Certification
Wild-caught sardines are generally of higher quality than farmed varieties. Look for the MSC (Marine Stewardship Council) or similar certification to ensure the fish were caught sustainably.
3. Sardines Packed in Water or Their Own Natural Juices (Low Sodium)
For those watching their oil intake, sardines packed in water are a lighter option. They are also lower in sodium than many of their oil-packed counterparts. You can always add your own healthy oil and seasoning at home.
How to Read a Sardine Can Label
- Look for the species. Sardines can be from various species. Smaller species like brisling or pilchards are generally milder and more tender.
- Check the packing liquid. Olive oil is best, but water or natural juices are good alternatives. Avoid soybean or cottonseed oil.
- Look for certifications. MSC, Dolphin Safe, or other sustainability labels are a good sign.
- Check the sodium content. A reasonable target is under 300 mg per serving.
- Look for a simple ingredient list. The best sardines contain only fish, oil or water, and salt.
