Fish is often listed among the healthiest foods. Its protein is easily digestible, fatty acids support heart and brain function, and the vitamins and micronutrients are good for the joints. But it’s not that simple.
The health benefits depend not just on the type of fish. What also matters is where it lived, what it ate, and how it was cooked. Sometimes a “healthy-looking” product hides toxins and heavy metals. So it’s better to focus on fat content, origin, and composition—not packaging or trends.
In this respect, ocean fish tends to be more reliable. It’s caught farther from shore, where there are fewer industrial discharges and cleaner water. Parasites are less common, and the Omega-3 content is higher. Good examples are sardines, cod, herring, and haddock.
Of course, there’s no such thing as a perfect product. But if you choose carefully—not by a flashy label, but by facts—fish can definitely be part of a healthy diet. Although we still lack solid data for some types, much depends on the region and season.
River fish is trickier. You’d think perch or zander would be fine—so what’s the issue? But quite often they carry liver flukes (opisthorchiasis). And regular frying won’t solve that. It’s better to boil or stew this kind of fish for a long time. As for river sashimi—it’s best to forget it altogether.
Another factor: the bigger the fish, the more likely it is to accumulate heavy metals. Tuna, for example, often contains high levels of mercury. But as always, it’s about quantity. Occasionally eating it is fine. Eating it in large portions all the time—not a great idea.
Farmed salmon is a separate story. It grows quickly on compound feed with additives. Its diet can include antibiotics, which affects the meat. This fish is fattier, which also means it may contain more toxins. Wild salmon is more trustworthy. It eats what it finds in nature, and its composition is simpler. Some say you can even tell the difference by looking—but that’s a skill of its own.
If your goal is to lose weight, lean fish is the way to go. Pollock, hake, cod, or zander contain up to 4% fat, have few calories, and still offer plenty of protein. These choices are also good for the elderly and children. They’re especially appropriate for people with low physical activity, like office workers or gamers—and increasingly, fans of online casinos. These users often spend hours lying on the couch with a phone in hand.
Then there are all-rounders—salmon, trout, chum. They have a moderate fat content, plenty of protein, and a rich taste. You can add them to a regular diet or a reduced-calorie meal plan.
More fatty options include mackerel, halibut, and chinook. Not ideal for daily meals, but no need to cut them out entirely either. They’re rich in Omega-3s, which are essential for brain health, blood vessels, and the immune system. Just watch your portion sizes.
As for frying—go easy on it. Frying reduces the vitamin and fatty acid content. What you get is a crispy crust and the smell of oil, but little actual benefit.
Baking is a better option. In foil, in a roasting bag, or steamed—it helps preserve both flavor and texture. Smoked fish isn’t ideal for regular meals: high in salt and potentially carcinogenic. The same goes for lightly salted fish. It’s okay once in a while, but not too often. Salt puts extra strain on the heart and kidneys.
