How we counted this

What 100 g gives you: imported foods have no serving size yet.

Your body needs enough of each of these. Past enough, more doesn’t help. Amounts are what the food databases list, not what your body absorbs, unless a row says it was measured.

The words: “A lot” means one serving gives 20% or more of Health Canada’s daily amount, “Some” 10% to 19%, “A little” 2% to 9%, “Almost none” under 2%. Strongest word first; within a word, protein and fibre lead, then the biggest share. ?

A milligram (mg) is a thousandth of a gram, and a microgram (µg) a thousandth of a milligram: 1,000 µg make 1 mg.

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.

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.
