Fish, whitefish, mixed species, smoked

Listed nutrients, per 100 g

For each nutrient, the value this page uses is marked “used”. A row marked “second database” is another database’s figure for a matching food, kept so you can see how far databases disagree (they can differ in the samples analysed, lab methods and rounding). Its own cells are worked out from it, but none of the page’s words or scores are.

Change the amount to rescale the first column. Nutrients a database doesn't list are missing, not zero.

Hazard rows as the dataset rates them

• Dioxins and dioxin-like PCBs · Worth knowing · Fish are a main source of dioxins and dioxin-like PCBs. EFSA's 2026 weekly limit protects the sons of future mothers, so this is a flag for women who are or may become pregnant, not a cap for everyone. Not measured for this food. · EFSA 2026
• Fish allergy · Worth knowing · Contains fish, a priority allergen (Health Canada). Not a label check: a mixed or processed food can contain allergens no default shows. · Health Canada, priority allergens
• Listeria · Worth knowing · Health Canada lists refrigerated smoked fish among the foods to avoid for people at higher risk of listeriosis (pregnancy, 60 and over, children up to 5, weakened immunity). Canned smoked fish is fine. · Health Canada, Food safety for vulnerable populations: foods to avoid
• Methylmercury · Context · Health Canada sets no consumption limit for retail fish other than fresh or frozen tuna, shark, swordfish, marlin, orange roughy and escolar (and canned albacore in pregnancy). Fish carry some methylmercury; the level in this one is not measured. · Health Canada, Mercury in Fish

Body map 2026-10-25.1: each nutrient’s job comes from an agency fact sheet, linked beside it under Good for.

The plain words: “a lot” means one serving (100 g when the food has no serving size) gives at least 20% of the daily amount (the reference intake), “some” at least 10%, “a little” at least 2% (the cut-offs are ours, one set for every page: 20% and 10% are borrowed from the US labelling terms “high” and “good source” and applied to Health Canada’s daily amount, whereas Health Canada’s own shopper rule says 15%; provisional: they may change in a later method version). The daily amount is Health Canada’s Dietary Reference Intake for adults 19–30; where men and women need different amounts we use the higher one (protein: 56 g for men, 46 g for women). The percentage printed under each nutrient is the printed amount as a share of that daily amount, rounded to the nearest whole number, and the word is read from that percentage, so the amount, the percentage and the word always agree. Calcium with a measured absorption is scaled by how well it gets in compared with milk.

The scale: “Nothing to watch” means a serving a day stays under the limit at ordinary amounts; “Go easy” means a serving a day can push past the limit for adults who already take in the most, or fewer than 2 servings reach it; “Limit it” means once a week or less. The dataset’s own rating is under “How we got this”. Provisional: the scale may change in a later method version.

Measured absorption under Good for: grade-A studies in adults that tested this preparation of this food, as a share of the listed amount (the share digested, for protein), quoted once each source has passed our evidence check; animal studies and other variants stay in the table above. Provisional: this screen may change in a later method version.
