How we counted this
What one serving (5.2 g) gives you.
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.
No nutrient we score reaches “some” in one serving. The rest, at “a little” or less, is below.

Watch out
How we counted this
Not tested for contaminants yet: what hasn’t been measured is listed below.
For some people
Flagged for people with asthma: Health Canada names bottled lemon and lime juices and concentrates among foods that often contain sulphites, and people with asthma are most at risk. Labelling applies at 10 ppm or more of added sulphites. No measured ppm for lemon juice exists; the CFIA sulphite survey (2015–19) holds no juice. The flag attaches to bottled juice; freshly squeezed juice carries none unless added.
Worth knowing
No limit applies, so none is rated.
Sugar
0.1 g of sugar in a 5.2 g serving, natural and added together.
Learn more
Shown, not rated. The food tables we read give total sugar, and few give added sugar, so the site can’t yet tell sugar added in making a food from the sugar in fruit or milk.

Noted for context, or not measured in this food yet.
Not measured in this food yet. Not rated: EFSA's 2009 tolerable weekly intake for cadmium is 2.5 µg/kg body weight/week, 175 µg a week for 70 kg. There is no as-eaten concentration for lemon juice: the nearest CFIA figures are for the whole fruit (peel included) or the concentrate, and converting needs a dilution factor that was not found. On the whole-fruit basis only, even at CFIA's highest lemon value (0.0063 µg/g), about 27,800 g a week would reach the limit, so no cap is likely at a 5.0 g serving, but that is not a row figure.
Shown as context, not rated: Health Canada says lemons, limes, citrons, sweet oranges and tangerines are not thought to have grapefruit's drug-interaction effect. But total furocoumarins in US retail juice put lime juice (14,579.7 ng/g) above grapefruit juice (9,534.1), with lemon juice (1,560.8) at about a sixth of grapefruit juice. The totals include compounds (bergapten) that are not CYP3A4 inhibitors, so they do not by themselves show a drug interaction; Chen 2018 reports lime juice with antimalarials as a beneficial combination, and no lemon-juice interaction of concern.
Not measured in this food yet. Not rated: no safe limit is set for lead (EFSA 2010 benchmark dose lower limit (BMDL01)), and there is no as-eaten concentration for lemon juice; the concentrate figure is not single-strength juice and the whole-fruit figure includes peel. For scale only, even 0.1564 µg/g (the concentrate maximum) in 5.2 g is 0.8 µg, 2.3% of the 35 µg a day average adult intake; that is an upper-end illustration, not a row value.
Context only, never scored. Imazalil 332 of 410 positive, mean of positives 0.377-2.08 ppm, max 13 ppm, 10 over the Canadian limit; thiabendazole 307 of 409; fludioxonil 201 of 408; dithiocarbamate 54 of 335 positive, 14 violations. Pesticides sit on the peel: for oranges, juice processing removed 63-100% of residues (Foods 2022 abstract). Lime import: pesticide screen 225 of 277 plus 56 of 104 positive; imazalil 140 of 271. Juice concentrates 2008-09: lemon imazalil mean 0.453 µg/g (n 5, all detected), chlorpyrifos 0.0303 (n 1), methidathion 0.0272 (n 1). No acceptable daily intake (ADI) arithmetic done.

How we counted this
“Better” here always means better at something the row names: more of one nutrient, more nutrients per serving, or the goal you pick. It never means better in every way.
Every amount below is for the same weight, 5.2 g, the size of one serving of this food, so a swap compares like with like. A serving of another food can be bigger or smaller.
Mayonnaise would lead this list, but it’s left out (Nothing to watch).
Your goal
Your goal changes only this list, not what the food gives you or what to watch.

Name in the database: Lemon juice, raw (freshly squeezed); lime juice as a variant in notes
How the serving was set: 5 mL, about 5.2 g (Health Canada TRA J.12, juices used as ingredients such as lemon juice or lime juice; 1 fl oz = 30.5 g in FDC 167747 gives 1.031 g/mL)
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.

Hazard rows as the dataset rates them
- Cadmium · Not rated yet · Not rated: EFSA's 2009 tolerable weekly intake for cadmium is 2.5 µg/kg body weight/week, 175 µg a week for 70 kg. There is no as-eaten concentration for lemon juice: the nearest CFIA figures are for the whole fruit (peel included) or the concentrate, and converting needs a dilution factor that was not found. On the whole-fruit basis only, even at CFIA's highest lemon value (0.0063 µg/g), about 27,800 g a week would reach the limit, so no cap is likely at a 5.0 g serving, but that is not a row figure. · CFIA chemical residue monitoring (2016–2023) · B
- Grapefruit-type drug interactions · Context · Shown as context, not rated: Health Canada says lemons, limes, citrons, sweet oranges and tangerines are not thought to have grapefruit's drug-interaction effect. But total furocoumarins in US retail juice put lime juice (14,579.7 ng/g) above grapefruit juice (9,534.1), with lemon juice (1,560.8) at about a sixth of grapefruit juice. The totals include compounds (bergapten) that are not CYP3A4 inhibitors, so they do not by themselves show a drug interaction; Chen 2018 reports lime juice with antimalarials as a beneficial combination, and no lemon-juice interaction of concern. · PubMed 28581738 · B
- Lead · Not rated yet · Not rated: no safe limit is set for lead (EFSA 2010 benchmark dose lower limit (BMDL01)), and there is no as-eaten concentration for lemon juice; the concentrate figure is not single-strength juice and the whole-fruit figure includes peel. For scale only, even 0.1564 µg/g (the concentrate maximum) in 5.2 g is 0.8 µg, 2.3% of the 35 µg a day average adult intake; that is an upper-end illustration, not a row value. · CFIA 2008 · B
- Pesticide residues · Context · Context only, never scored. Imazalil 332 of 410 positive, mean of positives 0.377-2.08 ppm, max 13 ppm, 10 over the Canadian limit; thiabendazole 307 of 409; fludioxonil 201 of 408; dithiocarbamate 54 of 335 positive, 14 violations. Pesticides sit on the peel: for oranges, juice processing removed 63-100% of residues (Foods 2022 abstract). Lime import: pesticide screen 225 of 277 plus 56 of 104 positive; imazalil 140 of 271. Juice concentrates 2008-09: lemon imazalil mean 0.453 µg/g (n 5, all detected), chlorpyrifos 0.0303 (n 1), methidathion 0.0272 (n 1). No acceptable daily intake (ADI) arithmetic done. · CFIA chemical residue monitoring (2016–2023) · A
- Sulphites · Worth knowing · Flagged for people with asthma: Health Canada names bottled lemon and lime juices and concentrates among foods that often contain sulphites, and people with asthma are most at risk. Labelling applies at 10 ppm or more of added sulphites. No measured ppm for lemon juice exists; the CFIA sulphite survey (2015–19) holds no juice. The flag attaches to bottled juice; freshly squeezed juice carries none unless added. · Health Canada · A
Oxalate, phytate and gut-tolerance measurements
- fodmap excess fructose: derived: fructose 1.1 minus glucose 0.99 = 0.11 g/100 g; 0.006 g in a 5.2 g serving, 0.05 g in the juice of one lemon (48 g); Varney 2017 line 0.40 g per serve, so far below it g/100 g · fresh weight · as sold · grade B · US food database (USDA SR Legacy)
- histamine: not detected (nd) in lemon, n 3 (own Spanish market database) mg/kg · fresh weight · as sampled · grade B · Sanchezperez 2018

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.
