Sardines Deliver More Omega-3s Per Ounce Than Salmon, With 382 mg Calcium per 100 Grams

Q: Why might cheaper, farmed Atlantic salmon actually deliver a stronger omega-3 punch than its expensive wild-caught cousin?

Cheaper farmed Atlantic salmon can deliver more omega-3s because it is usually fattier than many wild salmon. EPA and DHA are stored in that fat, so a fish with more total fat often provides more omega-3 per serving, even if it is less prized in the market. Feed is a major reason. Farmed salmon eat formulated diets designed to promote growth and fat deposition, and those feeds can be enriched with omega-3 sources such as fish oil or DHA-rich microalgae. Studies cited in the background material show that when Atlantic salmon feed includes more DHA-rich ingredients, the fish’s muscle DHA content rises. In other words, producers can partly “design” the omega-3 profile through feed. By contrast, wild salmon are not all nutritionally equal. Species differences matter a lot: wild sockeye and Chinook are often high in omega-3s, but leaner wild species such as pink salmon may contain much less. So an expensive wild fillet may cost more because of scarcity, seasonality, flavor, or sustainability appeal, not because it always contains more EPA and DHA. That does not automatically make farmed salmon nutritionally superior overall. Wild salmon often has a better omega-3-to-omega-6 ratio and may be leaner. But if the question is sheer omega-3 volume per portion, the extra fat in farmed Atlantic salmon can give it the edge. Packaging and cooking still matter, since draining oil-packed fish or frying at high heat can reduce the amount you actually consume.

Q: Could draining the oil from your canned fish be secretly stripping away the very nutrients you are trying to eat?

Yes—sometimes. Draining the oil from canned fish can reduce the omega-3s you actually eat, because some EPA and DHA move out of the fish and into the packing oil during canning and storage. Research on canned fish shows this “fatty acid exchange” is real. In oil-packed products, part of the fish’s omega-3 content can end up in the surrounding oil, so pouring that liquid away may mean discarding some of the nutrients you wanted. That is why experts say oil-packed fish is most beneficial if you consume some or all of the oil. By contrast, water- or brine-packed fish may be a better choice if you plan to drain the can, because there is less fat-rich liquid to lose. The type of oil matters too. Vegetable oils high in omega-6, such as sunflower or soybean oil, can alter the fish’s fatty-acid balance during storage. Aqueous packing media like water, brine, or tomato sauce generally preserve the fish’s omega-3 profile better. Olive oil may be a more favorable oil option than generic vegetable oil, though eating the liquid still adds calories. This does not mean drained canned fish becomes unhealthy. Sardines and salmon remain strong sources of protein and omega-3s even after processing, and sardines still provide major calcium benefits when eaten with their bones. If your goal is maximum omega-3 intake, choose water- or brine-packed fish when you want to drain it, or use the oil-packed fish and incorporate the oil into the meal instead of discarding it.

Sardines generally provide a higher omega-3 concentration per ounce than salmon, while salmon can still match that intake in a larger meal-sized portion.
Research cited in the report says sardines contain more than twice the DHA concentration of salmon and about the same EPA, though salmon varies widely by species—81 mg per gram in wild sockeye versus 10 mg in wild pink.
Processing and preparation can narrow or widen that gap: farmed Atlantic salmon showed slightly more EPA and DHA than wild, and canning left about 70% to 77% of EPA and DHA in the fish.
Nutritionally, canned sardines with bones add about 382 mg of calcium per 100 grams, while fresh boneless salmon has less than 100 mg and is usually lower in sodium.
The report concludes there is no universal winner for omega-3s, with the better choice depending on portion size, species, cooking method, cost, and taste.
