There is something wonderfully old-fashioned about opening a tin of sardines. No complicated preparation, no expensive kitchen equipment, and no long ingredient list are required; inside that little can is a fish naturally rich in protein, EPA and DHA omega-3 fats, vitamin B12, selenium, and, when the soft bones are included, calcium. Sardines also have another advantage that matters when choosing seafood regularly: the FDA places sardines in its “Best Choices” category for mercury, and FDA monitoring has found an average mercury concentration of about 0.013 ppm, considerably lower than many larger predatory fish. (U.S. Food and Drug Administration)
But the sardine aisle has become surprisingly complicated. Some tins contain nothing more than sardines, water, and perhaps salt. Others arrive swimming in sauces, vegetable oils, and enough sodium to substantially change the nutritional profile.
So rather than pretending there are five entire brands that everyone should “avoid,” it is more useful to look at five brands/SKUs worth seeking out and five types of cans I would be much more selective about. A brand can make an excellent plain sardine and a much less appealing flavored version at the same time.
1. BUY: Wild Planet
Wild Planet Wild Sardines in Extra Virgin Olive Oil
64,70 RON
Wild Planet is one of the easiest recommendations when the priority is a short ingredient list and clearly published nutritional information.
Its sardines in extra-virgin olive oil contain sardines, organic EVOO, water, sea salt, and natural smoke, while the water-packed version contains sardines, water, and sea salt. The company reports 18 grams of protein and 1,800 mg of EPA+DHA omega-3s per can for its water-packed sardines. (Wild Planet)
There is an even more interesting option for anyone watching sodium: Wild Planet’s no-salt-added sardines contain simply sardines and water, with 70 mg sodium per can according to its current label. (Wild Planet)
The company also states that its current cans use linings without intentionally added BPA. (Wild Planet)
This is exactly what I like seeing on a canned-fish label: recognizable fish, a simple packing medium, and very little else.
2. BUY: King Oscar
King Oscar has been selling canned seafood for generations, and its sardine range gives shoppers several useful choices.
One particularly attractive option is its Skinless & Boneless Sardines in Water, Low Sodium.
The ingredient list could hardly be simpler:
Sardines. Water.
According to King Oscar, a serving provides 17 grams of protein and 1,300 mg of omega-3s, while no salt is added. (kingoscar.com)
For someone new to sardines, skinless and boneless varieties can also be an easy introduction because the texture resembles familiar canned fish.
However, people who enjoy traditional whole sardines may want to keep the bones. Those tiny edible bones are one reason sardines can provide meaningful calcium.
3. BUY: Season
Season Skinless & Boneless Sardines in Olive Oil
115,31 RON
Wild Planet Wild Pacific Sardines in Extra Virgin Olive Oil
121,25 RON
Wild Planet Wild Sardines in Water
26,95 RON
Season Brand is another widely available name worth checking, particularly its simpler olive-oil varieties.
Season’s skinless and boneless sardines in olive oil are especially approachable for people who dislike seeing whole fish in the tin. They have a mild texture and work beautifully mashed onto whole-grain toast, folded into salads, or mixed with lemon and herbs.
There is a tradeoff, however.
Removing the bones makes the sardines easier for some people to eat, but it also removes much of the calcium advantage associated with whole bone-in sardines.
So think about your goal.
For convenience and protein, skinless and boneless can be excellent.
For maximum whole-fish nutrition, choose bone-in sardines.
4. BUY: Safe Catch
Safe Catch is worth knowing particularly for shoppers who pay attention to packaging.
The company states that its sardine cans use linings made without intentionally added BPA and says it performs third-party testing of finished products for BPA. (Safe Catch)
When buying its sardines, I would still use the same rule that applies to every brand: turn the can around.
Look at the exact variety rather than trusting the brand name alone.
Choose a simple water- or olive-oil-packed option when possible, and compare sodium between flavors.
That thirty-second label check is more useful than memorizing a “good brand/bad brand” list.
5. BUY: Bela
Bela Brand Seafood is a lovely option for someone who actually wants sardines to taste like a meal rather than merely treating them as a nutritional supplement.
Bela is particularly known for Portuguese sardines packed in olive oil, including lightly smoked varieties.
This is the kind of tin I would open and eat simply with lemon, parsley, tomatoes, cucumber, and a slice of good bread.
And that brings us to an important point.
The best sardine is one you genuinely enjoy enough to eat regularly.
A nutritionally perfect tin sitting untouched in the pantry provides considerably less benefit than a simple olive-oil sardine you happily eat every week.
Now, the 5 I Would Be Much More Careful With
I would not blacklist five entire companies, because that can be misleading. Recipes change, and many large brands sell both simple sardines and heavily seasoned varieties.
Instead, these are the five kinds of cans I would usually leave behind when a better version is sitting beside them.
1. Sardines Packed in Generic “Vegetable Oil”
Olive oil and water make shopping easy because you know exactly what the fish is packed in.
When a can simply lists generic vegetable oil, I would compare it with the olive-oil or water-packed tin beside it.
This does not transform the sardines into unhealthy food—the fish still provides valuable protein and omega-3 fats—but if two cans are similarly priced, I would generally reach for extra-virgin olive oil or water.
The packing liquid is part of the food, especially if you eat rather than drain it.
2. Extremely Salty Sardines
This is one of the biggest label differences shoppers overlook.
Sardines themselves are wonderfully nutritious, but sauces and brines can add substantial sodium.
Compare cans.
Wild Planet, for example, currently lists only 70 mg sodium in its no-salt-added water variety, compared with 280 mg in its regular water-packed sardines; another Wild Planet skinless/boneless water variety lists 380 mg. (Wild Planet)
Same general food.
Very different sodium numbers.
For someone eating canned fish frequently or deliberately reducing sodium, this comparison is worth making.
3. Sardines in Sugary Sauces
Tomato sauce itself can be wonderful.
Mustard can be wonderful.
Hot sauce can be wonderful.
The question is what else was added.
Some flavored canned seafood contains added sugars, considerable sodium, or lengthy sauce formulations.
Read the ingredient list.
If you want tomato sardines, a simple tin with sardines, tomato, spices, and modest salt can fit perfectly well.
What I would skip is a heavily sweetened sauce when an equally tasty simple option is available.
4. Sardines With an Unnecessarily Long Ingredient List
One of canned sardines’ greatest virtues is simplicity.
A beautiful label can literally read:
Sardines, water.
Or:
Sardines, extra-virgin olive oil, salt.
Once the ingredient panel starts resembling a paragraph, turn the neighboring can around and compare.
Often the simpler one is sitting only six inches away.
5. The Can You Buy Solely Because It Says “Low Mercury”
Here is the surprising one.
Mercury is important when selecting seafood, but sardines as a species are already among the lower-mercury choices.
The FDA classifies sardines as a “Best Choice,” and its historical monitoring data reported an average mercury concentration around 0.013 ppm. (U.S. Food and Drug Administration)
So when comparing two sardine brands, mercury usually isn’t the characteristic that separates an excellent tin from an ordinary one.
Instead, compare:
packing oil, sodium, ingredients, whether bones are retained, omega-3 content when disclosed, sourcing information, packaging, taste, and price.
Those differences are much more useful at the supermarket.
The Sardine Label I Would Look for
My ideal everyday can is almost boring.
Whole sardines with edible bones, packed in water or extra-virgin olive oil, with a short ingredient list and a reasonable amount of sodium.
Whole bone-in sardines provide the calcium advantage.
The fish supplies protein and omega-3s.
Olive oil provides unsaturated fat.
Add vegetables and suddenly the humble tin becomes an extraordinarily complete lunch.
My Favorite 5-Minute Sardine Lunch
Place a large handful of arugula or chopped romaine into a bowl and add tomatoes, cucumber, parsley, red onion, and white beans.
Open a tin of sardines packed in extra-virgin olive oil and place them over the vegetables.
Add lemon juice, black pepper, and a little of the olive oil from the tin.
Serve with a slice of whole-grain bread or a small boiled potato.
Now one tiny can has become a meal containing protein, omega-3 fats, vegetables, fiber, and satisfying fat.
That is where sardines become genuinely useful.
The Bottom Line
If I were standing in a U.S. supermarket today, the names I would look for first would include Wild Planet, King Oscar, Season, Safe Catch, and Bela, while still checking the exact can because products within the same brand can differ substantially.
And rather than fearing sardines because of mercury, remember that the FDA specifically places them among its lower-mercury “Best Choices.” (U.S. Food and Drug Administration)
The real supermarket secret is much simpler:
Turn the can around.
Choose sardines packed in water or extra-virgin olive oil, favor a short ingredient list, compare sodium, keep the soft bones when you want the calcium, and choose a flavor you will genuinely enjoy.
Sometimes one of the healthiest foods in the grocery store really does come in a tiny metal tin. 🐟❤️
