Greek yogurt, plain, nonfat

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

• Cadmium · Nothing to watch: under the limit · A daily serving adds 0.15% to an average adult's cadmium intake (EFSA 2012 adult median, 1.77 µg/kg body weight/week; Canadian adults in 2007: 1.2-1.75), far from doubling it, so no cap. · Health Canada Total Diet Study, trace elements · B
• Dairy and ciprofloxacin · Worth knowing · Worded as the label puts it: the ciprofloxacin label names yogurt; it is not to be taken with dairy alone, but may be taken with a meal that contains it. · Ciprofloxacin Tablets, USP, US generic label · B
• Histamine · Nothing to watch: under the limit · No cap for healthy adults: EFSA's no-effect level is 50 mg of histamine per meal. The highest of 16 cow's-milk yogurts measured 3.05 mg/kg (14 had none detected), so a 115 g serving carries at most 0.35 mg, 0.7% of it. Sheep's-milk yogurts in the same study reached 17.16 mg/kg (1.97 mg per serving, 3.9%). EFSA's level for people with histamine intolerance is 'below detectable limits'. · Moniente 2023 · B
• Lead · Nothing to watch: doesn’t double average intake · Lower bound 0.697, upper bound 0.826 µg/kg (2 of 17 composites non-detect, detection limits 0.39 and 1.8, counted as 0 in the lower bound). A daily serving adds 0.23-0.27% to EFSA's average adult intake (35 µg/day), so no cap. 2016-18 mean 0.494 (n 3). FDA Total Diet Study lowfat vanilla and lowfat fruit-flavored yogurt: 0 of 3 detects each, reporting limit 4 µg/kg (an upper bound at that limit would be 0.46 µg per serving, 1.3%). · Health Canada Total Diet Study, trace elements · B
• Milk allergy · Worth knowing · Milk is a Health Canada priority allergen; the Health Canada milk page lists yogurt among common sources of milk · Health Canada 2017 · A

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.
