Salmon vs Mackerel
Side-by-side nutrition comparison per serving. See which fits your goals better.
Salmon and mackerel are nutritional twins at first glance — 208 vs 205 calories, 20.4g vs 18.6g protein, 13.4g vs 13.9g fat per 100g. The macros are so close you might wonder why this comparison even exists. But dig beneath the surface numbers and these are meaningfully different fish.
Mackerel is the omega-3 heavyweight champion. Atlantic mackerel packs even more EPA and DHA per serving than salmon, which is already considered the gold standard. It's also one of the most sustainable fish you can eat — mackerel populations are robust, the fish reproduce quickly, and they're low on the food chain, meaning minimal mercury accumulation.
The reason salmon wins the popularity contest is taste and texture. Salmon is buttery, clean, and approachable. Mackerel is intensely fishy, oily, and polarizing. People either love it or can't get past the first bite. Canned mackerel in particular has a strong flavor that takes getting used to. If you can develop a taste for it, mackerel gives you everything salmon does at a fraction of the price. Fresh mackerel is often the cheapest fatty fish at the counter.
Pro tip
Canned mackerel in olive oil is an underrated meal-prep shortcut. Flake it over rice bowls with pickled ginger, cucumber, soy sauce, and sesame seeds for a 5-minute omega-3 bomb. The strong flavor works perfectly in bold Asian-inspired preparations where salmon's subtlety would actually be a disadvantage.
