Coffee, brewed, decaffeinated

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.

Change the amount to rescale the first column. Nutrients a database doesn't list are missing, not zero.

Hazard rows as the dataset rates them

• Acrylamide · Nothing to watch: doesn’t double average intake · No cap: of 13 FDA Total Diet Study composites of decaffeinated ground coffee (2003-2006), 84.6% were below the 10 ppb quantitation limit. Counting those at half the limit gives a mean of 6.4 µg/kg, so a cup carries 1.6 µg of acrylamide: 7.9% to 14.5% of the average adult's 11.0-20.2 µg/day, well below the doubling line. No safe threshold is set for acrylamide. In EFSA's consultation text for dry roasted coffee, decaffeinated is 319 µg/kg against 245 for regular, so decaf is not lower in acrylamide. · FDA 2002–2006 · A
• Caffeine · Nothing to watch: under the limit · No cap: a decaf cup carries 2.5 mg of caffeine, 1% of the 400 mg a day that EFSA (2015) and Health Canada give for adults, and adds 1% to 7% to the average adult's intake. Eaten alone, about 40,000 g a day would reach the limit. Measured decaf varies: Health Canada gives 3 mg per 237 mL, and a study of ten shops found 0 to 13.9 mg per 16 oz, so a decaf cup is 3-14 mg and the listing's 2.5 mg is the low end. · US food database (USDA SR Legacy) · B
• Caffeine in one sitting · Nothing to watch: under the limit · No cap: EFSA (2015) puts the single dose that raises no safety concern for healthy adults at 200 mg, about 3 mg/kg body weight. A decaf cup carries 2.5 mg, 1% of it; eaten alone, about 20,000 g in one sitting would reach it. Measured decaf varies: Health Canada gives 3 mg per 237 mL, and a study of ten shops found 0 to 13.9 mg per 16 oz, so a decaf cup is 3-14 mg and the listing's 2.5 mg is the low end. · US food database (USDA SR Legacy) · B
• Furan · Go easy: can double average intake · May exceed: furan has no safe level set for its cancer effect, so a cup is judged by what it adds to the average adult's intake. Commercially brewed decaffeinated coffee in Canada (mean 53.1 µg/kg, 12 samples) gives 13.3 µg of furan a cup, or 0.190 µg/kg body weight. That adds 25% to EFSA's highest adult average (0.75 µg/kg body weight/day) and 173% to its lowest (0.11), so at the low end a daily cup more than doubles average intake. At that low end total intake stays under the non-cancer limit the dataset carries (benchmark dose lower limit (BMDL10) 64 µg/kg body weight/day, with a margin of 100). · Becalski 2016 · 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.
