Shelled pistachios

Pistachios, dry-roasted

Checked by us One serving: 30 g · 172 kcal

Lots of vitamin B6.

Go easy: aflatoxins can add up.

Worth knowing for some people: choking risk under age 4; nickel for people who are sensitised.

How we counted this

What one serving (30 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.

  • Aflatoxins

    +38–564% a serving a day adds to an average adult’s intake from all food

    That share is for one serving, 30 g, every day. Eaten once a week instead, the same serving adds a seventh as much: 5.4–81%, not 38–564%.

    No amount of aflatoxins is proven harmless, so we compare with what people already take in instead of counting to a limit. We flag a food only when a daily serving would double that average.

    “Go easy” here because agencies’ estimates of what an average adult takes in differ, and against the lowest of them a serving a day can double it.

    One serving carries 86.9 ng (AFB1, lower bound)

    How we got this

    The dataset’s rating: Go easy: can double average intake

    May exceed: no safe limit is set for aflatoxin B1; EFSA's 2020 reference point is a benchmark dose lower limit (BMDL10) of 0.4 µg/kg body weight/day. A 30 g serving adds 86.9 ng at the lower-bound mean of 2.896 µg/kg (95.9 ng on the upper bound), 1.24 ng/kg body weight/day at 70 kg. Against EFSA's adult mean exposure (lower bound 0.22-0.49, upper bound 1.35-3.25 ng/kg body weight/day) that is +253% to +564% on the lower-bound pairs and +42% to +101% on the upper-bound pairs, so the range reaches the doubling line. 84% of 6,126 European results were non-detects, and raw and processed pistachios are pooled.

  • Acrylamide

    Nothing to watch

    You’d need about 5 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 9.7–22% to what an average adult already takes in. There is no limit to take a share of.

    One serving carries 6.1 µg (acrylamide, at 204 µg/kg)

    How we got this

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

    No cap: no safe limit is set for acrylamide; EFSA's 2015 reference point is a benchmark dose lower limit (BMDL10) of 0.17 mg/kg body weight/day. A 30 g serving at 204 µg/kg carries 6.1 µg (0.09 µg/kg body weight/day), and at 594 µg/kg 17.8 µg (0.25); against EFSA's adult mean exposure of 0.4-0.9 µg/kg body weight/day that adds +10% to +64%, under the doubling line. Those values come from lab roasting in Iran, so the true retail range is unknown; a 44-nut commercial survey found acrylamide from not detected up to 123.6 µg/kg across all nuts, below every cell of the roasting grid.

Checked for nickel, cadmium, aluminum, lead and ochratoxin A: fine at normal amounts.

For some people

  • Health Canada: nuts are not safe for children younger than four years (whole or in pieces).

  • Flagged for people with nickel contact allergy: EFSA's 2020 lowest-observed-adverse-effect level is 4.3 µg Ni/kg body weight after a single oral dose, 301 µg at 70 kg. A 30 g serving carries 19 µg (0.27 µg/kg body weight), a margin of 16, while EFSA treats a margin of 30 or more as low concern. About 475 g would reach the level itself, and 16 g leaves a margin of 30.

  • Measured, not rated: 12.6 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: the only figure is 42 mg oxalate per 100 g from a patient-foundation list (Oxalosis and Hyperoxaluria Foundation, 2024) that cites no primary analysis and states no method. For people who form calcium-oxalate stones, a 30 g serving works out to 12.6 mg, under the list's own 25 mg low-oxalate line.

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

  • Context only: total arsenic, no inorganic share stated and no reference value applied. 30 g at 188.8 µg/kg = 5.7 µg total As. CFIA imports 2016-19 (n 3, all positive) pooled mean 0.016 ppm = 16 µg/kg, about 12 times lower than the Polish retail value: the two sources disagree and neither separates the inorganic fraction.

  • Context only (pesticide residues are not scored). Positives are mostly neonicotinoids at 0.01-0.1 ppm; none above a limit.

  • Shown as context, not rated: in a US FDA retail survey of raw shelled nuts, about 7 of 295 pistachio samples (2.37%, 95% CI 0.96-4.83) carried Salmonella, with macadamias highest at 2.52% and cashews at 0.20%. This is not applied to dry-roasted pistachios, since commercial roasting is a kill step and no roasted-pistachio prevalence was found.

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, 30 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 snacks or toppings 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 snacks or toppings we’ve checked give clearly more, in the same 30 g.

More nutrients per serving, counted together

The other snacks or toppings 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.

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.

  • Acrylamide · Nothing to watch: doesn’t double average intake · No cap: no safe limit is set for acrylamide; EFSA's 2015 reference point is a benchmark dose lower limit (BMDL10) of 0.17 mg/kg body weight/day. A 30 g serving at 204 µg/kg carries 6.1 µg (0.09 µg/kg body weight/day), and at 594 µg/kg 17.8 µg (0.25); against EFSA's adult mean exposure of 0.4-0.9 µg/kg body weight/day that adds +10% to +64%, under the doubling line. Those values come from lab roasting in Iran, so the true retail range is unknown; a 44-nut commercial survey found acrylamide from not detected up to 123.6 µg/kg across all nuts, below every cell of the roasting grid. · PubMed 32566205 · C
  • Aflatoxins · Go easy: can double average intake · May exceed: no safe limit is set for aflatoxin B1; EFSA's 2020 reference point is a benchmark dose lower limit (BMDL10) of 0.4 µg/kg body weight/day. A 30 g serving adds 86.9 ng at the lower-bound mean of 2.896 µg/kg (95.9 ng on the upper bound), 1.24 ng/kg body weight/day at 70 kg. Against EFSA's adult mean exposure (lower bound 0.22-0.49, upper bound 1.35-3.25 ng/kg body weight/day) that is +253% to +564% on the lower-bound pairs and +42% to +101% on the upper-bound pairs, so the range reaches the doubling line. 84% of 6,126 European results were non-detects, and raw and processed pistachios are pooled. · EFSA 2020 · A
  • 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 a week at 70 kg. At the CFIA mean of 0.343 ppm (3 samples, all positive), about 204,082 g of pistachios in a week, eaten alone, would reach it. A 30 g serving every day adds 72 µg a week, 0.10% of the limit. · CFIA chemical residue monitoring (2016–2023) · A
  • Arsenic, all forms · Context · Context only: total arsenic, no inorganic share stated and no reference value applied. 30 g at 188.8 µg/kg = 5.7 µg total As. CFIA imports 2016-19 (n 3, all positive) pooled mean 0.016 ppm = 16 µg/kg, about 12 times lower than the Polish retail value: the two sources disagree and neither separates the inorganic fraction. · Bielecka 2021 · B
  • Cadmium · Nothing to watch: under the limit · A daily serving adds 0.76% 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. · Bielecka 2021 · B
  • Choking risk under age 4 · Worth knowing · Health Canada: nuts are not safe for children younger than four years (whole or in pieces). · Health Canada, Nutrition for Healthy Term Infants: Recommendations… · A
  • Lead · Nothing to watch: doesn’t double average intake · No cap: no safe limit is set for lead; EFSA's 2010 reference point is a benchmark dose lower limit (BMDL01) of 0.5 µg/kg body weight/day. A 30 g serving at the Polish retail mean of 21.73 µg/kg (10 samples) carries 0.65 µg, 0.0093 µg/kg body weight/day, 1.9% of that reference point. A Canadian survey found lead in 1 of 3 samples (9.1 µg/kg). · Bielecka 2021 · B
  • 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 a day at 70 kg. At the CFIA mean of 0.634 ppm (3 samples, all positive), about 1,435 g of pistachios in one day, eaten alone, would reach it (968 g at the highest annual value, 0.94 ppm). A 30 g serving carries 19 µg, 2% of the limit, and adds 9% to EFSA's adult median background of 3.16 µg/kg body weight/day (+7% to +13% across surveys), under the doubling line; 3 samples is thin. · CFIA chemical residue monitoring (2016–2023) · A
  • Nickel for people who are sensitised · Worth knowing · Flagged for people with nickel contact allergy: EFSA's 2020 lowest-observed-adverse-effect level is 4.3 µg Ni/kg body weight after a single oral dose, 301 µg at 70 kg. A 30 g serving carries 19 µg (0.27 µg/kg body weight), a margin of 16, while EFSA treats a margin of 30 or more as low concern. About 475 g would reach the level itself, and 16 g leaves a margin of 30. · EFSA 2020 · A
  • Ochratoxin A · Nothing to watch: doesn’t double average intake · No cap: no safe limit is set for ochratoxin A; EFSA's 2020 reference point is a benchmark dose lower limit (BMDL10) of 14.5 µg/kg body weight/day (14,500 ng/kg body weight/day). A 30 g serving at the CFIA lower-bound mean of 0.01667 ng/g (30 samples, 5 detected) carries 0.50 ng, 0.0071 ng/kg body weight/day; even at the highest sample, 0.13 ng/g, it is 3.9 ng, 0.056 ng/kg body weight/day. · CFIA ochratoxin A survey (2012–2022) · B
  • Oxalate for kidney-stone formers · Not rated yet · Not rated: the only figure is 42 mg oxalate per 100 g from a patient-foundation list (Oxalosis and Hyperoxaluria Foundation, 2024) that cites no primary analysis and states no method. For people who form calcium-oxalate stones, a 30 g serving works out to 12.6 mg, under the list's own 25 mg low-oxalate line. · Oxalosis and Hyperoxaluria Foundation 2024 · B
  • Pesticide residues · Context · Context only (pesticide residues are not scored). Positives are mostly neonicotinoids at 0.01-0.1 ppm; none above a limit. · CFIA chemical residue monitoring (2016–2023) · A
  • Salmonella · Context · Shown as context, not rated: in a US FDA retail survey of raw shelled nuts, about 7 of 295 pistachio samples (2.37%, 95% CI 0.96-4.83) carried Salmonella, with macadamias highest at 2.52% and cashews at 0.20%. This is not applied to dry-roasted pistachios, since commercial roasting is a kill step and no roasted-pistachio prevalence was found. · PubMed 33438200 · A
  • Tree nut allergy · Worth knowing · Pistachio is a Health Canada priority tree nut allergen: flagged for people with a tree nut allergy. (Cashew and pistachio are botanical relatives of the same family, Anacardiaceae, and cross-react clinically; not sourced here.) · Health Canada, Tree Nuts - Priority food allergens · 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.
