A heap of boiled mustard greens

Mustard greens, cooked

Checked by us One serving: 85 g (about ⅔ cup chopped) · 22 kcal

Lots of vitamin K1, vitamin A and vitamin C.

Not tested for contaminants yet.

On warfarin? Keep your vitamin K steady. Worth knowing for some people: uncooked frozen vegetables.

Good for

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.

Watch out

How we counted this

Not tested for contaminants yet: what hasn’t been measured is listed below.

For some people

  • Flag based on Health Canada's produce-safety page: frozen packaged vegetables must be cooked; outbreaks have been linked to uncooked ones; pregnant women and children under 5 are among the higher-risk groups. The advice is for frozen packaged vegetables as a whole, not for mustard greens in particular, hence grade B. It applies only if a frozen listing is added.

  • For people on warfarin, as the label puts it: keep vitamin K intake consistent, not avoid. Listed vitamin K: raw 257.5 µg/100 g (about 219 µg per 85 g), cooked 592.7 µg/100 g (about 504 µg per 85 g) (SR Legacy 169256 and 169257).

    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 504 µg of vitamin K1.

Worth knowing

No limit applies, so none is rated.

  • Sugar

    1.2 g of sugar in a 85 g serving, natural and added together.

    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.

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.

Compared with the other vegetables we’ve checked.

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

More vitamin A

  • Carrots, raw710 µg in 85 g (this food: 525 µg) · but less vitamin K1 and vitamin C

More vitamin C

  • Red pepper, raw109 mg in 85 g (this food: 21.5 mg) · but less vitamin K1 and vitamin A
  • Green pepper, raw84.6 mg in 85 g (this food: 21.5 mg) · but less vitamin K1 and vitamin A

Amounts as listed, not adjusted for how much gets in.

For vitamin K1: 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.

  • Kale, cooked
    • More omega-3: ALA (286 mg vs 18.7 mg)
    • More folate (55.3 µg vs 7.65 µg)
    • Less vitamin K1 (355 µg vs 504 µg)
    • Less vitamin A (124 µg vs 525 µg)

1 food out of the 23 other vegetables we’ve checked and could compare gives clearly more nutrients per serving.

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.

  • Turnip greens, cooked
    • 17 kcal in 85 g (this food: 22)
    • More folate (100 µg vs 7.65 µg)
    • Less vitamin K1 (312 µg vs 504 µg)
    • Less vitamin A (324 µg vs 525 µg)

1 food out of the 23 other vegetables we’ve checked and could compare gives clearly more nutrients, protein and fibre per calorie.

Why some foods aren’t suggested

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

Left out: Edamame, cooked (not tested for contaminants yet).

Open every value

Name in the database: Mustard greens, cooked, boiled, drained

How the serving was set: 85 g (Health Canada V.1, vegetables without sauce; fresh or frozen)

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.

Sources

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.
