How we counted this

What one serving (9.2 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.

  • 3-MCPD and its esters

    Nothing to watchHealth Canada pilot, Ottawa retail corn oil, one brand

    You’d need about 55 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 1.66 µg (3-MCPD equivalents)

    How we got this

    A serving a day adds 3.4–12% 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 36–39% of the limit.

    The highest average adult intake we found already takes up about 35% 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, 780 g a day would reach the limit.

    Why this rating: Eating it daily comes to 9 g a day, which stays within the 510 g of room left before the limit.

    The dataset’s rating: Nothing to watch: under the limit

    No cap: the tolerable daily intake for 3-MCPD and its fatty acid esters is 2 µg/kg body weight/day (EFSA 2018), 140 µg a day for 70 kg. About 778 g of corn oil eaten alone in a day would reach it (586 g at the highest single analysis, 239 ng/g). A serving carries 1.66 µg, 1.2% of it, and adds 3.4-11.8% to the average adult's 0.2-0.7 µg/kg body weight/day (14-49 µg/day), which is under half the limit.

      A serving a day adds 9.5–33% 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 38–47% of the limit.

      The dataset’s rating: Nothing to watch: under the limit

      No cap: the tolerable daily intake for 3-MCPD and its fatty acid esters is 2 µg/kg body weight/day (EFSA 2018), 140 µg a day for 70 kg. EFSA's European mean for maize oil (38 results) is 503 µg/kg, so about 278 g of oil eaten alone in a day would reach it. A serving carries 4.63 µg, 3.3% of it, and adds 9.5-33.1% to the average adult's 0.2-0.7 µg/kg body weight/day (14-49 µg/day), which is under half the limit. European data, shown beside the Canadian figures, not averaged with them. The mean is 2.8 times the Canadian retail mean for the same oil type (180 ng/g).

    How we got this

    The dataset’s rating: Nothing to watch: rated by margin of exposure

    No cap: MOAH (mineral oil aromatic hydrocarbons) has no safe threshold and is judged by margin of exposure, using EFSA 2023's surrogate reference point of 0.49 mg/kg body weight/day for the 3+-ring fraction; a margin of 10,000 or higher is low concern. A serving carries 0.3-17.6 µg MOAH. If 10% of MOAH is 3+-ring (EFSA's first scenario) the serving's own margin is 19,498 at the upper bound; at 1% (second scenario), 194,985. Against EFSA's adult average total-MOAH exposure of 0.0004 to 0.006 mg/kg body weight/day, a serving adds 0.07-62.8%, short of doubling; the range is wide because it pairs the serving's lowest figure with the highest background and its highest with the lowest. European data (edible maize oil, 37 samples, 97% below detection), not Canadian retail.

    No cap: glycidol is a genotoxic carcinogen with no safe threshold, judged by margin of exposure (EFSA 2016: T25 10.2 mg/kg body weight/day; a margin of 25,000 or higher is low concern). A serving carries 1.29 µg, 0.0184 µg/kg body weight/day, a margin of 553,746 on its own. The average adult takes in 0.2-0.3 µg/kg body weight/day (EFSA 2016, middle bound), a margin of 51,000 to 34,000, and a serving adds 6.1-9.2% to it, short of doubling (the highest single analysis, 159 ng/g, would add up to 10%).

For some people

  • Flagged for people on warfarin, as the label puts it: keep vitamin K intake consistent, not avoid. Corn oil is a poor source of vitamin K1: the Institute of Medicine puts it under 5 µg per 100 g, against more than 100 for soybean and canola oils (2001). A serving of corn oil carries about 0.2 µg of vitamin K1, against an adequate intake of 120 µg a day for men and 90 for women. A flag for consistency, not a cap.

    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 0.2 µg of vitamin K1.

Worth knowing

  • Context hazard (EFSA 2023 no-observed-adverse-effect level (NOAEL) 236 mg/kg body weight/day; 'present dietary exposure to mineral oil saturated hydrocarbons (MOSH) does not raise concern'): a serving = 0.042-0.055 mg = 0.00059-0.00079 mg/kg body weight/day; MoE against the NOAEL 298,950-397,717. No cap.

  • Shown as context, not rated: WHO (2023) advises no more than 1% of total energy from trans fat, and Health Canada's public-health objective is less than 1%; on a 2,000 kcal diet that is 2.22 g a day. A serving carries 0.041 g, 1.9% of it. This is the trans fat formed when oil is refined, not from partially hydrogenated oil; Health Canada's 2017 notice puts non-hydrogenated refined oils at generally less than 2% of the oil.

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, 9.2 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.

Compared with the other butters, oils and dressings 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.

Name in the database: Vegetable oil, corn (refined)

How the serving was set: 10 mL = 9.21 g (Health Canada TRA H.2 'Vegetable oil, including liquid coconut oil', 10 mL, label '2 tsp (10 mL)'; grams from USDA SR Legacy household measures: 1 cup = 218 g, 1 US cup = 236.588 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

  • Glycidyl esters (glycidol) · Nothing to watch: doesn’t double average intake · No cap: glycidol is a genotoxic carcinogen with no safe threshold, judged by margin of exposure (EFSA 2016: T25 10.2 mg/kg body weight/day; a margin of 25,000 or higher is low concern). A serving carries 1.29 µg, 0.0184 µg/kg body weight/day, a margin of 553,746 on its own. The average adult takes in 0.2-0.3 µg/kg body weight/day (EFSA 2016, middle bound), a margin of 51,000 to 34,000, and a serving adds 6.1-9.2% to it, short of doubling (the highest single analysis, 159 ng/g, would add up to 10%).

  • Glycidyl esters (glycidol) · Nothing to watch: doesn’t double average intake · No cap: glycidol is a genotoxic carcinogen with no safe threshold, judged by margin of exposure (EFSA 2016: T25 10.2 mg/kg body weight/day; a margin of 25,000 or higher is low concern). A serving of maize oil carries 5.99 µg, 0.086 µg/kg body weight/day, a margin of 119,268 on its own. The average adult takes in 0.2-0.3 µg/kg body weight/day (EFSA 2016, middle bound), a margin of 51,000 to 34,000, and a serving adds 29-43% to it, short of doubling; the maize figure rests on only 36 results. European data (36 results, 6% below detection), shown beside the Canadian figures, not averaged with them. · DOI 10.2903/j.efsa.2016.4426 · A
  • 3-MCPD and its esters · Nothing to watch: under the limit · No cap: the tolerable daily intake for 3-MCPD and its fatty acid esters is 2 µg/kg body weight/day (EFSA 2018), 140 µg a day for 70 kg. About 778 g of corn oil eaten alone in a day would reach it (586 g at the highest single analysis, 239 ng/g). A serving carries 1.66 µg, 1.2% of it, and adds 3.4-11.8% to the average adult's 0.2-0.7 µg/kg body weight/day (14-49 µg/day), which is under half the limit.

  • 3-MCPD and its esters · Nothing to watch: under the limit · No cap: the tolerable daily intake for 3-MCPD and its fatty acid esters is 2 µg/kg body weight/day (EFSA 2018), 140 µg a day for 70 kg. EFSA's European mean for maize oil (38 results) is 503 µg/kg, so about 278 g of oil eaten alone in a day would reach it. A serving carries 4.63 µg, 3.3% of it, and adds 9.5-33.1% to the average adult's 0.2-0.7 µg/kg body weight/day (14-49 µg/day), which is under half the limit. European data, shown beside the Canadian figures, not averaged with them. The mean is 2.8 times the Canadian retail mean for the same oil type (180 ng/g). · DOI 10.2903/j.efsa.2016.4426 · A
  • Mineral oil aromatic hydrocarbons (MOAH) · Nothing to watch: rated by margin of exposure · No cap: MOAH (mineral oil aromatic hydrocarbons) has no safe threshold and is judged by margin of exposure, using EFSA 2023's surrogate reference point of 0.49 mg/kg body weight/day for the 3+-ring fraction; a margin of 10,000 or higher is low concern. A serving carries 0.3-17.6 µg MOAH. If 10% of MOAH is 3+-ring (EFSA's first scenario) the serving's own margin is 19,498 at the upper bound; at 1% (second scenario), 194,985. Against EFSA's adult average total-MOAH exposure of 0.0004 to 0.006 mg/kg body weight/day, a serving adds 0.07-62.8%, short of doubling; the range is wide because it pairs the serving's lowest figure with the highest background and its highest with the lowest. European data (edible maize oil, 37 samples, 97% below detection), not Canadian retail. · DOI 10.2903/j.efsa.2023.8215 · B
  • Mineral oil saturated hydrocarbons (MOSH) · Context · Context hazard (EFSA 2023 no-observed-adverse-effect level (NOAEL) 236 mg/kg body weight/day; 'present dietary exposure to mineral oil saturated hydrocarbons (MOSH) does not raise concern'): a serving = 0.042-0.055 mg = 0.00059-0.00079 mg/kg body weight/day; MoE against the NOAEL 298,950-397,717. No cap. · DOI 10.2903/j.efsa.2023.8215 · B
  • Trans fats · Context · Shown as context, not rated: WHO (2023) advises no more than 1% of total energy from trans fat, and Health Canada's public-health objective is less than 1%; on a 2,000 kcal diet that is 2.22 g a day. A serving carries 0.041 g, 1.9% of it. This is the trans fat formed when oil is refined, not from partially hydrogenated oil; Health Canada's 2017 notice puts non-hydrogenated refined oils at generally less than 2% of the oil. · Canadian Nutrient File 2026 · B
  • Vitamin K and warfarin · Worth knowing · Flagged for people on warfarin, as the label puts it: keep vitamin K intake consistent, not avoid. Corn oil is a poor source of vitamin K1: the Institute of Medicine puts it under 5 µg per 100 g, against more than 100 for soybean and canola oils (2001). A serving of corn oil carries about 0.2 µg of vitamin K1, against an adequate intake of 120 µg a day for men and 90 for women. A flag for consistency, not a cap. · US food database (USDA SR Legacy) · C

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.
