Alaskan pollock is one of the healthiest and most affordable fish you can eat. At just 92 calories per 100 grams, it delivers roughly 40% of your daily protein needs while staying extremely low in mercury and fat. It’s also one of the most consumed fish in the United States, showing up in everything from fish sticks to fast-food sandwiches to imitation crab.
Protein and Calories
Pollock is a lean white fish, which means it packs a lot of protein relative to its calorie count. A 100-gram serving (about 3.5 ounces) contains 92 calories and enough protein to cover nearly half your daily requirement. For context, that’s comparable to chicken breast in protein density but with far fewer calories than most cuts of meat. If you’re trying to increase protein intake without adding much fat or caloric load, pollock is one of the most efficient options in the seafood case.
Omega-3s and Heart Health
Pollock contains a meaningful amount of omega-3 fatty acids, the type linked to cardiovascular protection and reduced inflammation. It won’t match the omega-3 levels of fatty fish like salmon or mackerel, but it still contributes to your weekly intake, especially if you eat it regularly.
The broader benefit of eating fish like pollock shows up clearly in inflammation research. People who eat more than 300 grams of fish per week (roughly two generous servings) have about 33% lower levels of C-reactive protein and interleukin-6, two key markers of the chronic inflammation that drives heart disease. Even eating 150 to 300 grams per week produces measurable reductions. Pollock is an easy, inexpensive way to hit those numbers.
Iodine and Micronutrients
One nutrient that makes pollock stand out is iodine. A 100-gram serving provides around 44 to 67 micrograms of iodine, depending on the source and preparation. The recommended daily intake for most adults is 150 micrograms, so a single serving of pollock gets you roughly a third of the way there. Iodine is essential for thyroid function, and many people don’t get enough of it from their diet alone. Pollock also supplies vitamin B12, selenium, and phosphorus, all nutrients that support energy metabolism, immune function, and bone health.
Mercury Levels Are Very Low
Mercury is the main safety concern people have about fish, and pollock performs exceptionally well here. FDA testing found a mean mercury concentration of just 0.031 parts per million in pollock. To put that in perspective, canned light tuna averages 0.126 ppm, cod averages 0.111 ppm, and halibut averages 0.241 ppm. Pollock’s mercury level is close to that of salmon (0.022 ppm for fresh or frozen), which is widely considered one of the safest fish available.
This low mercury level is why the EPA and FDA place pollock in their “Best Choices” category for fish consumption. That’s the highest safety tier, recommended for children and pregnant women. You can safely eat two to three servings per week without concern about mercury accumulation.
Sustainability
The Bering Sea pollock fishery in Alaska is one of the largest and best-managed fisheries in the world. NOAA Fisheries has called it “a model of sustainability.” If you’re choosing fish with both your health and environmental impact in mind, Alaskan pollock checks both boxes. Look for products labeled with the Marine Stewardship Council (MSC) certification or sourced from Alaska to ensure you’re getting fish from this well-regulated fishery.
Whole Fillets vs. Processed Pollock
Here’s where things get more complicated. A plain pollock fillet baked or pan-seared is a straightforward healthy meal. But most pollock in the American diet doesn’t arrive that way. It’s processed into breaded fish sticks, fast-food fillets, or surimi (imitation crab), and each of those forms changes the nutritional picture significantly.
Imitation crab is the most dramatic transformation. Surimi, the minced pollock paste that forms its base, makes up only 35% to 50% of the finished product by weight. The rest is water, starch (potato, wheat, corn, or tapioca), added sugars, salt, and stabilizers like carrageenan and xanthan gum. A typical serving contains around 450 milligrams of sodium. The protein and omega-3 content drops considerably compared to a whole fillet, while the carbohydrate and sodium content climbs. It’s not a terrible food, but it’s a very different nutritional proposition than the fish it started as.
Breaded and fried pollock products add refined carbohydrates and cooking oil, which can double or triple the calorie count of a plain fillet. If you’re eating pollock specifically for its health benefits, whole fillets prepared with minimal added fat will give you the best return. Frozen fillets are widely available and typically inexpensive, making them one of the most budget-friendly ways to eat more fish.
How Pollock Compares to Other Fish
- Vs. salmon: Salmon has significantly more omega-3s and a richer flavor, but costs two to four times as much. Pollock is leaner and milder, making it easier to eat frequently.
- Vs. cod: Nutritionally similar, but pollock has lower mercury (0.031 ppm vs. 0.111 ppm for cod) and is generally cheaper.
- Vs. tilapia: Both are mild white fish, but pollock typically has more omega-3s and a better omega-3 to omega-6 ratio. Both are low in mercury.
- Vs. tuna: Canned light tuna has four times the mercury of pollock. Pollock is a safer option for frequent consumption, especially for children.
For people who want to eat fish regularly without worrying about mercury or breaking their grocery budget, Alaskan pollock is one of the smartest choices available. It’s nutritionally dense, sustainably sourced, and versatile enough to work in tacos, soups, grain bowls, or simply alongside vegetables on a sheet pan.
