Two ripe bananas

Banana, raw

Checked by us One serving: 140 g (about 1 large banana) · 136 kcal

Lots of vitamin B6.

Nothing to watch for most people.

Worth knowing for some people: latex-fruit syndrome.

Good for

How we counted this

What one serving (140 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.

Checked for cadmium and lead: fine at normal amounts.
  • Cadmium

    Nothing to watch

    You’d need about 98 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 0.07 µg

    How we got this

    A serving a day adds 0.4% 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, 330,000 g a week would reach the limit.

    Why this rating: Eating it daily comes to 980 g a week, which stays within the 96,000 g of room left before the limit.

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

    A daily serving adds 0.42% 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.

  • Lead

    Nothing to watch

    You’d need more than 100 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.

    A serving a day adds 0.3% to what an average adult already takes in. There is no limit to take a share of.

    One serving carries 0.1 µg

    How we got this

    The dataset’s rating: Nothing to watch: doesn’t double average intake

    Adds 0.28% to the average adult lead intake (0.50 µg/kg body weight/day = 35 µg/day, EFSA 2012), far from doubling it, so no cap. Without the 1999 composite the mean is 0.623 µg/kg (n = 16); the three most recent composites 0.513; FDA Total Diet Study item 80: 0 of 27 detected, reporting limit 4 µg/kg.

For some people

  • Banana is one of the four fruits most often involved in latex-fruit syndrome (review; prevalence among latex-allergic patients 4-88% by method and region). A separate Turkish series of 47 children with a banana reaction history and positive banana IgE reacted in 13% of double-blind challenges.

Worth knowing

No limit applies, so none is rated.

  • Sugar

    17 g of sugar in a 140 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.

Also measured in it

Figures from the dataset. None has a limit to be rated against, so none is a verdict.

  • Tyramine: 0–1.9 mg per kg fresh weight, so about 0–0.26 mg in a 140 g serving. (mean 0.53 (standard deviation 0.79), range ND-1.85) · Sanchezperez 2021 · grade B

    For scale, EFSA found no reported ill effects at 6 mg of tyramine in a meal for people on the older MAO-inhibitor antidepressants, 50 mg for those on the newer ones and 600 mg for healthy people not taking them, based on limited data. EFSA 2011

Noted for context, or not measured in this food yet.

  • Shown as context: one serving carries 456 mg potassium, about 13% of the 3,400 mg adequate intake for men or 17.5% of 2,600 mg for women. Relevant to people with kidney disease or on potassium-raising drugs, not a general hazard. A case report exists, 'Hyperkalemia and hyperdopaminemia induced by an obsessive eating of banana in an anorexia nervosa adolescent' (title only read).

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, 140 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 fruits 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

For vitamin B6: no other fruits we’ve checked give clearly more, in the same 140 g.

More nutrients per serving, counted together

The other fruits 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.

  • Kiwi, raw
    • More vitamin C (105 mg vs 17.2 mg)
    • More vitamin K1 (56.4 µg vs 0.14 µg)
    • More vitamin E (1.82 mg vs 0.14 mg)
    • Less vitamin B6 (0.09 mg vs 0.29 mg)
  • Mango, raw
    • More vitamin C (51 mg vs 17.2 mg)
    • More folate (60.2 µg vs 19.6 µg)
  • Pineapple, raw
    • More vitamin C (82.1 mg vs 17.2 mg)
    • Less vitamin B6 (0.15 mg vs 0.29 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.

  • Raspberries, raw
    • 72 kcal in 140 g (this food: 136)
    • More fibre (9.1 g vs 2.38 g)
    • More vitamin C (32.3 mg vs 17.2 mg)
    • Less vitamin B6 (0.08 mg vs 0.29 mg)
  • Raspberries, frozen
    • 78 kcal in 140 g (this food: 136)
    • More riboflavin (0.14 mg vs 0 mg)
    • Less vitamin B6 (0.09 mg vs 0.29 mg)
  • Strawberries, raw
    • 46 kcal in 140 g (this food: 136)
    • More vitamin C (83.5 mg vs 17.2 mg)
    • Less vitamin B6 (0.07 mg vs 0.29 mg)

The numbers

Open every value

Name in the database: Banana, raw

How the serving was set: 140 g edible (peeled) weight (Health Canada TRA row J.1, fruit, fresh; the edible weight is used)

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.

Absorption studies

Studies of how much of a nutrient gets in; those done in animals are marked. This page quotes a figure only from a study that passes our screen: adults, graded A, of this food in this preparation, with a test dose on record and a source that has passed our evidence check. The exception is calcium on our calcium card: its figure comes from the card’s own study, checked with the card, and is marked “used” even where that study misses a step of this screen. The others are listed so nothing is hidden, each with the first check it fails.

No study of this food passes the screen yet, so no absorption figure is quoted.

Hazard rows as the dataset rates them

  • Cadmium · Nothing to watch: under the limit · A daily serving adds 0.42% 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. · Health Canada Total Diet Study, trace elements · A
  • Latex-fruit syndrome · Worth knowing · Banana is one of the four fruits most often involved in latex-fruit syndrome (review; prevalence among latex-allergic patients 4-88% by method and region). A separate Turkish series of 47 children with a banana reaction history and positive banana IgE reacted in 13% of double-blind challenges. · PubMed 39064262 · B
  • Lead · Nothing to watch: doesn’t double average intake · Adds 0.28% to the average adult lead intake (0.50 µg/kg body weight/day = 35 µg/day, EFSA 2012), far from doubling it, so no cap. Without the 1999 composite the mean is 0.623 µg/kg (n = 16); the three most recent composites 0.513; FDA Total Diet Study item 80: 0 of 27 detected, reporting limit 4 µg/kg. · Health Canada Total Diet Study, trace elements · A
  • Potassium-restricted diets · Context · Shown as context: one serving carries 456 mg potassium, about 13% of the 3,400 mg adequate intake for men or 17.5% of 2,600 mg for women. Relevant to people with kidney disease or on potassium-raising drugs, not a general hazard.

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.
