How we counted this
What one serving (15 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.
- A lot
Omega-3: ALA
The one omega-3 your body can’t make: it must come from food. Your cells build it into their membranes and burn it for energy.

Missing from our databases for this food, so left out, not counted as zero: vitamin A, vitamin K1, vitamin B6 and choline.
Watch out
How we counted this
Nickel
Nothing to watchYou’d need about 22 servings in a day of this food alone to use up what the highest average adult intake we found leaves under the limit.
Learn more
One serving carries 30.8 µg
How we got this
The highest average adult intake we found already takes up about 26% of the limit. One serving a day fits in the room left.
Counted from zero, with no allowance for what adults already take in from other food, 440 g a day would reach the limit.
Why this rating: Eating it daily comes to 15 g a day, which stays within the 330 g of room left before the limit.
The dataset’s rating: Nothing to watch: under the limit
No cap: EFSA's 2020 tolerable daily intake for nickel is 13 µg/kg body weight/day, 910 µg/day for 70 kg. At the highest annual CFIA mean (2.05 µg/g, 38 samples), about 444 g of chia a day would reach it. A 15.0 g serving carries 31 µg, 3.4% of the limit, and adds 14% to the median adult background of 3.16 µg/kg body weight/day (221 µg/day; 11–22% across surveys), shown, not subtracted.
Checked for aluminum, cadmium, glyphosate residues, lead and ochratoxin A: fine at normal amounts.
Aluminum
Nothing to watchYou’d need about 14 servings a day, every day, of this food alone to reach the limit.
Learn more
One serving carries 683 µg (at 45.5 ppm)
How we got this
1,500 g a week reaches the limit
The dataset’s rating: Nothing to watch: under the limit
No cap: EFSA's tolerable weekly intake for aluminium is 1 mg/kg body weight/week, 70,000 µg/week for 70 kg. At the highest annual CFIA mean (45.5 µg/g, 38 samples), about 1,540 g of chia a week eaten alone would reach it (23,400 g at the lowest annual mean, 2.99). A 15.0 g serving every day (105 g a week) is 4,780 µg, 6.8% of the limit, and 41% at the single highest sample (273 ppm). Chia carries 37 to 78 times the aluminium of the three nuts in its family.
Cadmium
Nothing to watchYou’d need about 53 servings a day, every day, of this food alone to use up what an average adult’s intake leaves under the limit.
Learn more
One serving carries 0.14 µg (at 9.1 µg/kg)
How we got this
A serving a day adds 0.8% to what an average adult already takes in: a share of that intake, not of the limit. With that serving every day, an average adult would be at about 71% of the limit.
An average adult already takes in about 71% of the limit. One serving a day fits in the room left.
Counted from zero, with no allowance for what adults already take in from other food, 19,000 g a week would reach the limit.
Why this rating: Eating it daily comes to 105 g a week, which stays within the 5,600 g of room left before the limit.
The dataset’s rating: Nothing to watch: under the limit
A daily serving adds 0.77% 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.
Glyphosate residues
Nothing to watchYou’d need more than 100 servings in a day of this food alone to reach the limit.
Learn more
One serving carries 3.72 µg (glyphosate, at 0.248 ppm)
How we got this
140,000 g a day reaches the limit
The dataset’s rating: Nothing to watch: under the limit
No cap: EFSA's 2023 acceptable daily intake for glyphosate is 0.5 mg/kg body weight/day, 35,000 µg/day for 70 kg. The mean of positives is 0.248 ppm (2 of 9 CFIA import samples positive, maximum 0.269 ppm), so the grams figure is a floor: about 141,000 g of chia a day. A 15.0 g serving at that level carries 3.7 µg, 0.01% of the limit. The 2 violations were of the Canadian residue limit, not of a health-based limit.
Lead
Nothing to watchYou’d need about 84 servings a day, every day, of this food alone to double the lead an average adult already gets. No dose is known to be safe, so doubling is where we flag.
Learn more
A serving a day adds 1.2% to what an average adult already takes in. There is no limit to take a share of.
One serving carries 0.41 µg (at 27.3 µg/kg)
How we got this
The dataset’s rating: Nothing to watch: doesn’t double average intake
No cap: no safe level of lead is set, so there is no grams figure; the rating rests on what a serving adds to average intake. A 15.0 g serving at the highest annual mean (27.3 µg/kg) carries 0.41 µg, about 1.2% of an average adult's 35 µg/day (EFSA 2012); the single highest sample (145 µg/kg) would give 2.2 µg, 6%. The data are CFIA import samples of whole seed (38 samples, 33 positive); milling does not change the concentration.
Ochratoxin A
Nothing to watchYou’d need more than 100 servings a day, every day, of this food alone to double the ochratoxin A an average adult already gets. No dose is known to be safe, so doubling is where we flag.
Learn more
A serving a day adds 0.3–1% to what an average adult already takes in. There is no limit to take a share of.
One serving carries 1.15 ng (OTA, lower bound)
How we got this
The dataset’s rating: Nothing to watch: doesn’t double average intake
No cap: no safe level of ochratoxin A is set (EFSA 2020 benchmark dose lower limit (BMDL10) 14.5 µg/kg body weight/day), so there is no grams figure. The CFIA lower-bound mean is 0.07684 ng/g (44 samples, 18 detected), so a 15.0 g serving carries 1.15 ng, 0.0165 ng/kg body weight/day; the maximum sample (1.14 ng/g) would give 17 ng, 0.24 ng/kg body weight/day. The margin to the reference point is about 880,000 at the mean; average background exposure was not compared.
For some people
Flagged for people sensitised to nickel: EFSA's 2020 lowest-observed-adverse-effect level is 4.3 µg Ni/kg body weight, 301 µg for 70 kg. A 15.0 g serving carries 31 µg (0.44 µg/kg body weight), a margin of 9.8 to that level, where EFSA treats a margin of 30 or more as low concern. About 147 g would reach the level; staying at a margin of 30 means about 4.9 g.
Measured, not rated: 70.5 mg oxalate
Learn more
We haven’t rated this food for oxalate. We count only a figure that comes from a grade A or B source and says it was measured per 100 g of the food as eaten, and none of the figures here does both.
How we got this
Not rated: no agency sets an oxalate intake limit; this is information for people who form calcium-oxalate stones. A patient-foundation list gives 470 mg/100 g for one brand, with no stated method, so 15 g carries 70.5 mg, a moderate portion by the list's bands (25–99 mg); 100 g would fall in its very-high band.

Noted for context, or not measured in this food yet.
Not measured in this food yet. Missing, not estimated. EFSA's unspecified 'Other seeds' line (n 71, mean lower bound 4.069 / upper bound 4.621 µg/kg AFB1, 72% left-censored) is not chia and is not used; linseed (n 175, lower bound 0.0036 / upper bound 0.365) is a different seed.
Context, not a flag: Health Canada's list of foods unsafe for children under four names "seeds" without saying whole or milled; milled seed stirred into food is not the listed hazard, and no agency statement on ground chia exists. The adult dry-swallowing concern about whole chia (it swells in liquid) does not arise for a powder.
Context only (pesticide residues are not scored): 4 positives in 146 screens, none flagged as violations except the two glyphosate results above.
Context only, and about a different product: sprouted chia seed powder (dried, ground, sprouted seeds), not whole dry chia seed. No survey of Salmonella in whole chia was found; the 2012 Irish nut-and-seed survey (FSAI 10NS1) listed no chia sample among its top varieties.
Shown as context, not rated: this is one recall event, not an occurrence rate. In January 2026 the CFIA recalled one lot of 900 g Left Coast Organics organic whole chia seeds (Class 2, no illnesses reported) for possible Salmonella, triggered by a recall in another country. It was whole seed, but grinding does not kill Salmonella, so whole and ground chia carry the same record.
Better options
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, 15 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.
A food is listed only if it gives clearly more: at least a fifth more than this food, and at least 10% of the daily amount more.

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
- Aflatoxins · Not rated yet · Missing, not estimated. EFSA's unspecified 'Other seeds' line (n 71, mean lower bound 4.069 / upper bound 4.621 µg/kg AFB1, 72% left-censored) is not chia and is not used; linseed (n 175, lower bound 0.0036 / upper bound 0.365) is a different seed. · EFSA 2020 · C
- Aluminum · Nothing to watch: under the limit · No cap: EFSA's tolerable weekly intake for aluminium is 1 mg/kg body weight/week, 70,000 µg/week for 70 kg. At the highest annual CFIA mean (45.5 µg/g, 38 samples), about 1,540 g of chia a week eaten alone would reach it (23,400 g at the lowest annual mean, 2.99). A 15.0 g serving every day (105 g a week) is 4,780 µg, 6.8% of the limit, and 41% at the single highest sample (273 ppm). Chia carries 37 to 78 times the aluminium of the three nuts in its family. · CFIA chemical residue monitoring (2016–2023) · A
- Cadmium · Nothing to watch: under the limit · A daily serving adds 0.77% 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. · CFIA chemical residue monitoring (2016–2023) · A
- Choking risk under age 4 · Context · Context, not a flag: Health Canada's list of foods unsafe for children under four names "seeds" without saying whole or milled; milled seed stirred into food is not the listed hazard, and no agency statement on ground chia exists. The adult dry-swallowing concern about whole chia (it swells in liquid) does not arise for a powder. · Health Canada, Nutrition for Healthy Term Infants: Recommendations… · A
- Glyphosate residues · Nothing to watch: under the limit · No cap: EFSA's 2023 acceptable daily intake for glyphosate is 0.5 mg/kg body weight/day, 35,000 µg/day for 70 kg. The mean of positives is 0.248 ppm (2 of 9 CFIA import samples positive, maximum 0.269 ppm), so the grams figure is a floor: about 141,000 g of chia a day. A 15.0 g serving at that level carries 3.7 µg, 0.01% of the limit. The 2 violations were of the Canadian residue limit, not of a health-based limit. · CFIA chemical residue monitoring (2016–2023) · A
- Lead · Nothing to watch: doesn’t double average intake · No cap: no safe level of lead is set, so there is no grams figure; the rating rests on what a serving adds to average intake. A 15.0 g serving at the highest annual mean (27.3 µg/kg) carries 0.41 µg, about 1.2% of an average adult's 35 µg/day (EFSA 2012); the single highest sample (145 µg/kg) would give 2.2 µg, 6%. The data are CFIA import samples of whole seed (38 samples, 33 positive); milling does not change the concentration. · CFIA chemical residue monitoring (2016–2023) · A
- Nickel · Nothing to watch: under the limit · No cap: EFSA's 2020 tolerable daily intake for nickel is 13 µg/kg body weight/day, 910 µg/day for 70 kg. At the highest annual CFIA mean (2.05 µg/g, 38 samples), about 444 g of chia a day would reach it. A 15.0 g serving carries 31 µg, 3.4% of the limit, and adds 14% to the median adult background of 3.16 µg/kg body weight/day (221 µg/day; 11–22% across surveys), shown, not subtracted. · CFIA chemical residue monitoring (2016–2023) · A
- Nickel for people who are sensitised · Worth knowing · Flagged for people sensitised to nickel: EFSA's 2020 lowest-observed-adverse-effect level is 4.3 µg Ni/kg body weight, 301 µg for 70 kg. A 15.0 g serving carries 31 µg (0.44 µg/kg body weight), a margin of 9.8 to that level, where EFSA treats a margin of 30 or more as low concern. About 147 g would reach the level; staying at a margin of 30 means about 4.9 g. · EFSA 2020 · A
- Ochratoxin A · Nothing to watch: doesn’t double average intake · No cap: no safe level of ochratoxin A is set (EFSA 2020 benchmark dose lower limit (BMDL10) 14.5 µg/kg body weight/day), so there is no grams figure. The CFIA lower-bound mean is 0.07684 ng/g (44 samples, 18 detected), so a 15.0 g serving carries 1.15 ng, 0.0165 ng/kg body weight/day; the maximum sample (1.14 ng/g) would give 17 ng, 0.24 ng/kg body weight/day. The margin to the reference point is about 880,000 at the mean; average background exposure was not compared. · CFIA ochratoxin A survey (2012–2022) · A
- Oxalate for kidney-stone formers · Not rated yet · Not rated: no agency sets an oxalate intake limit; this is information for people who form calcium-oxalate stones. A patient-foundation list gives 470 mg/100 g for one brand, with no stated method, so 15 g carries 70.5 mg, a moderate portion by the list's bands (25–99 mg); 100 g would fall in its very-high band. · Oxalosis and Hyperoxaluria Foundation 2024 · B
- Pesticide residues · Context · Context only (pesticide residues are not scored): 4 positives in 146 screens, none flagged as violations except the two glyphosate results above. · CFIA chemical residue monitoring (2016–2023) · A
- Salmonella · Context · Context only, and about a different product: sprouted chia seed powder (dried, ground, sprouted seeds), not whole dry chia seed. No survey of Salmonella in whole chia was found; the 2012 Irish nut-and-seed survey (FSAI 10NS1) listed no chia sample among its top varieties. · PHAC 2014 · A
- Salmonella · Context · Shown as context, not rated: this is one recall event, not an occurrence rate. In January 2026 the CFIA recalled one lot of 900 g Left Coast Organics organic whole chia seeds (Class 2, no illnesses reported) for possible Salmonella, triggered by a recall in another country. It was whole seed, but grinding does not kill Salmonella, so whole and ground chia carry the same record. · CFIA 2026 · 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.
