Pollock, a type of fish commonly found in the North Pacific, is not only a popular choice for culinary dishes but also offers numerous health benefits. This article explores the various health advantages of consuming pollock, supported by scientific research.

Improvement in Lipid Metabolism

Pollock oil is rich in n-3 polyunsaturated fatty acids (PUFAs) and long-chain monounsaturated fatty acids (MUFAs), which have been shown to modulate risk factors associated with metabolic syndrome. In a study involving diet-induced obese mice, pollock oil supplementation significantly reduced plasma lipid levels, including total cholesterol, LDL cholesterol, and triglycerides, while increasing plasma adiponectin levels. These changes were associated with a decrease in hepatic steatosis and downregulation of hepatic genes involved in cholesterol and lipid metabolism, indicating an improvement in lipid metabolism1.

Reduction in Serum Cholesterol and Glucose Levels

The processing of Alaska pollock protein into kamaboko protein has been found to mitigate elevated serum cholesterol and postprandial glucose levels. In an experiment with obese Zucker rats, diets containing Alaska pollock protein significantly reduced serum total cholesterol levels and improved glucose tolerance compared to a control diet. This suggests that pollock protein can be beneficial in managing cholesterol and glucose levels, which are critical factors in preventing cardiovascular diseases and diabetes2.

Iron Nutritional Status Enhancement

Pollock frames have been used to derive ferrous-ion-chelating peptides, which have shown promise in improving iron nutritional status. In a study with iron-deficient anaemic rats, these peptides effectively restored body weight, haemoglobin, serum iron, and transferrin levels. The results indicate that pollock-derived peptides can serve as a potent source of iron supplementation, potentially benefiting individuals with iron deficiency anaemia4.

Anti-inflammatory Properties

Collagen peptides derived from Alaska pollock skin have demonstrated significant anti-inflammatory effects. In a mouse model of burn-induced inflammation, supplementation with these peptides reduced serum endotoxin levels and the concentration of inflammatory markers such as TNF-α and IL-6. This suggests that pollock collagen peptides could be used as an immunonutrient supplement to improve outcomes in patients with inflammatory conditions, such as those recovering from burns5.

Conclusion

Pollock offers a range of health benefits, from improving lipid metabolism and reducing cholesterol and glucose levels to enhancing iron nutritional status and providing anti-inflammatory effects. These findings highlight the potential of pollock as a valuable component of a healthy diet, contributing to the prevention and management of various health conditions.
