Fish oil, cod liver vs Oil, hazelnut
Original comparison by NutriVerdict
Bottom line: Fish oil, cod liver is the more nutrient-dense of the two, scoring 88 of 100 to 60 for Oil, hazelnut.
Cod liver fish oil scores well ahead of hazelnut oil, 88 of 100 versus 60 of 100, despite both foods sharing nearly identical macronutrients in this data: 100 g fat per 100 g, no protein, carbs, fiber, or sodium, and calories within 20 kcal of each other, 902 versus 884. The large score gap comes down to factors beyond the macros captured here, since fat, protein, and carb numbers alone do not explain a 28-point difference.
Choose cod liver oil when the nutrient density score is the priority, since it ranks well above hazelnut oil in this category despite the similar calorie and fat counts. Choose hazelnut oil for its distinct flavor in cooking, where the macro profile will not differ meaningfully from the fish oil. Honestly, the macronutrient numbers alone do not tell the full story behind this score gap.
