*Where the numbers come from
Values per 100 g come from a single record of an open food composition table: USDA FoodData Central, FDC ID 174200, “Fish, halibut, Atlantic and Pacific, raw” — the measured composition of this exact food, raw, as you weigh it before cooking, not an average across tables. Rounded. Carbohydrates are total carbohydrate, fiber included, as on a US Nutrition Facts label; salt is sodium × 2.5. Table licenses are on the data sources page.

How we judge this, and the sources
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on November 1, 2026. The short food description was written by our language model (AI) — how we check the text.

*Where the vitamin numbers come from
Vitamins and minerals come from the USDA FoodData Central record “Fish, halibut, Atlantic and Pacific, raw” (FDC ID 174200, SR Legacy; public domain), checked October 14, 2026; the record was matched to this food by calories, protein and fat. % DV is per serving, against the FDA Daily Values used on Nutrition Facts labels (2,000-calorie diet). The table lists nutrients that reach at least 2% DV per 100 g; the rest are absent or trace. Varieties, seasons and brands differ, and cooking in water leaches some vitamin C and B vitamins.
