Checked by us One serving: 85 g (about 1 cup chopped) · 105 kcal
Lots of omega-3: ALA. Much of the ALA comes from the oil it was cooked in.
Nothing to watch for most people.
On warfarin? Keep your vitamin K steady.

How we counted this
What one serving (85 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.
Mostly from the cooking oil: the same weight raw has next to none.

561 mg in one serving: 35% of the 1,600 mg a day men need, 51% of the 1,100 mg women need. The word follows the smaller share, which is the share of the higher amount. ?

Missing from our databases for this food, so left out, not counted as zero: vitamin A, vitamin B12 and selenium.
Watch out
How we counted this
Acrylamide
Nothing to watchYou’d need about 10 servings a day, every day, of this food alone to double the acrylamide 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 4.9–11% to what an average adult already takes in. There is no limit to take a share of.
One serving carries 3.1 µg
How we got this
The dataset’s rating: Nothing to watch: doesn’t double average intake
No safe threshold (EFSA benchmark dose lower limit (BMDL10) 0.17 mg/kg body weight/day; adult average 0.4-0.9 µg/kg body weight/day, 28-63 µg/day at 70 kg). At the mean, 36 µg/kg, an 85 g serving carries 3.1 µg, adding 4.9-10.9%; at the median, 14 µg/kg, 1.2 µg (+1.9-4.2%): far from doubling, so no cap. The single highest sample (420 µg/kg, 36 µg per 85 g) would add 57-127%; the rating uses the mean, and the maximum is shown so the spread is visible.
For some people
With warfarin: keep vitamin K intake consistent (label), not avoid.
Learn more
Eat a steady amount, not none. This line goes on every food whose serving gives 10% or more of the daily vitamin K; a few foods below that carry it too, where a source names them. One serving here has about 18 µg of vitamin K1.
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, 85 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.
More of what it’s good for
For omega-3: ALA: no other vegetables we’ve checked give clearly more, in the same 85 g.
More nutrients per serving, counted together
The other vegetables we’ve checked with more nutrients per serving than this one, counting at most 100 kcal. One score ranks them all, so the same few often lead.
Turnip greens, cooked- More vitamin K1 (312 µg vs 18.4 µg)
- More folate (100 µg vs 1.7 µg)
- More vitamin C (23.3 mg vs 1.53 mg)
- Less omega-3: ALA (54.4 mg vs 561 mg)
Kale, cooked- More vitamin K1 (355 µg vs 18.4 µg)
- More vitamin C (15.1 mg vs 1.53 mg)
- More folate (55.3 µg vs 1.7 µg)
- Less omega-3: ALA (286 mg vs 561 mg)
- Less vitamin B6 (0.05 mg vs 0.18 mg)
Brussels sprouts, cooked- More vitamin K1 (119 µg vs 18.4 µg)
- More vitamin C (52.7 mg vs 1.53 mg)
- More folate (51 µg vs 1.7 µg)
- Less omega-3: ALA (147 mg vs 561 mg)
Where the calcium card measured that less calcium gets in than from milk, calcium counts for less; everything else is as listed.
Your goal
Your goal changes only this list, not what the food gives you or what to watch.
Losing weight: fewer calories, and more nutrients, protein and fibre for each calorie.

- More folate (47.6 µg vs 1.7 µg)
- Less omega-3: ALA (35.7 mg vs 561 mg)
None of the 22 other vegetables we could compare gives clearly more protein, and more calories, per 100 g.

Left out: Spinach, cooked (Cadmium: go easy · lots of oxalate, more than its own calcium can bind).

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
- Acrylamide · Nothing to watch: doesn’t double average intake · No safe threshold (EFSA benchmark dose lower limit (BMDL10) 0.17 mg/kg body weight/day; adult average 0.4-0.9 µg/kg body weight/day, 28-63 µg/day at 70 kg). At the mean, 36 µg/kg, an 85 g serving carries 3.1 µg, adding 4.9-10.9%; at the median, 14 µg/kg, 1.2 µg (+1.9-4.2%): far from doubling, so no cap. The single highest sample (420 µg/kg, 36 µg per 85 g) would add 57-127%; the rating uses the mean, and the maximum is shown so the spread is visible. · PubMed 32231929 · B
Oxalate, phytate and gut-tolerance measurements
- histamine: no distinct difference between raw and fried onion (n = 3 each, ELISA); the numbers are in Fig. 3, which could not be opened; the review that cites it says histamine was 'well below 1 mg/kg' in every food before and after frying ppm (= mg/kg) · fresh weight, ground sample · fried at 150 C for 1-5 minutes in a preheated pan with 10 ml soy bean oil (the paper's words: 'fried') · grade B · PubMed 29200758

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.
