Claim 1 of 6OverstatedWhile Americans have been drinking roughly the same amount of coffee over recent years, the calories in those cups have increased thanks primarily to the addition of non-dairy creamer, according to a new study from researchers at Tufts University.View evidenceHide evidence

Why this verdict

The abstract-level profile supports the core trend: total coffee consumption by weight was stable while energy from coffee increased, and the authors attribute the increase primarily to non-dairy creamer. However, the headline wording “increased thanks primarily to” frames this as a causal-strength explanation from a serial cross-sectional NHANES analysis. The paper evidence supports a population-level trend/decomposition, not causal inference. The headline wording also outruns the more numeric, associational body claims.

Study evidence

Total coffee consumption by weight was stable from 2003 to 2018 (373 to 378 g/day; difference 4.49 g/day; p=0.791 for trend).4.49 g/day (p=0.791)

“DESIGN: This study is a serial cross-sectional analysis.”

Study evidence

In 2017–2018, coffee additions totaled 40.9 g/day; the most common additions by weight were dairy milk (21.4 g/day), non-dairy creamer (8.1 g/day), and sugar (4.4 g/day).dairy milk 21.4 g/day; non-dairy creamer 8.1 g/day; sugar 4.4 g/day

“coffee consumption is often accompanied by the addition of milk, non-dairy creamer, sugar, or sugar substitutes”

Claim 2 of 6Not coveredThe researchers also found that adults with fewer hours of sleep or longer working hours consumed more coffee than those with more sleep or shorter working hours, and that coffee consumption was similar among individuals with high versus low diet quality.View evidenceHide evidence

Why this verdict

The abstract-level profile reports subgroup differences by sex, race/ethnicity, and income, but it does not report findings about sleep duration, working hours, or diet quality. These claims may depend on full-text analyses not available in the abstract-level profile, so they are not verifiable at this depth.

Study evidence

Higher total coffee consumption was observed among men, non-Hispanic White adults, and individuals with higher income compared with their counterparts (as stated in the abstract).

“Higher total coffee consumption was observed among men, non-Hispanic White adults, and individuals with higher income compared with their counterparts.”

Claim 3 of 6SupportedThe study analyzed reported dietary intake of 30,000 U.S. adults aged 20 and over and found that between 2003 and 2018, total coffee consumption remained stable at roughly 13 ounces per day, while energy from coffee increased from 43 kcal/day to 60 kcal/day.View evidenceHide evidence

As stated43 kcal/day to 60 kcal/day; roughly 13 ounces/day

Why this verdict

The profile reports NHANES 2003–2018 data on U.S. adults aged 20+ with n=30,459, stable total coffee consumption by weight from 373 to 378 g/day, and increased energy from total coffee from 43 to 60 kcal/day. The story’s “roughly 13 ounces/day” is consistent with the reported gram/day and cup equivalents.

Study evidence

Total coffee consumption by weight was stable from 2003 to 2018 (373 to 378 g/day; difference 4.49 g/day; p=0.791 for trend).4.49 g/day (p=0.791)

“DESIGN: This study is a serial cross-sectional analysis.”

Study evidence

“coffee consumption is often accompanied by the addition of milk, non-dairy creamer, sugar, or sugar substitutes”

Claim 4 of 6SupportedThe most common coffee additions by calories in 2018 were non-dairy creamer, sugar or syrup, and dairy milk.View evidenceHide evidence

Why this verdict

The profile reports that by energy contribution in 2017–2018, non-dairy creamer contributed the most energy, followed by sugar and dairy milk. The story’s “2018” is a shorthand for the 2017–2018 NHANES cycle. The abstract profile names “sugar,” not specifically “sugar or syrup,” so that wording is slightly less exact, but the ranked calorie-contribution claim is supported.

Study evidence

“coffee consumption is often accompanied by the addition of milk, non-dairy creamer, sugar, or sugar substitutes”

Claim 5 of 6SupportedBy 2018, non-dairy creamer added the largest amount of calories to coffee at 18.5 kcal/day, followed by sugar at 16 kcal/day and dairy milk at 11 kcal/day.View evidenceHide evidence

As stated18.5 kcal/day; 16 kcal/day; 11 kcal/day

Why this verdict

The profile reports the same ordering and essentially the same magnitudes: non-dairy creamer about 19 kcal/day, sugar 16 kcal/day, and dairy milk 11 kcal/day in 2017–2018. The story’s 18.5 kcal/day for non-dairy creamer is compatible with the rounded profile value.

Study evidence

“coffee consumption is often accompanied by the addition of milk, non-dairy creamer, sugar, or sugar substitutes”

Claim 6 of 6SupportedThe authors note a limitation that self-reported recall data are subject to measurement error due to day-to-day variation in food intake.View evidenceHide evidence

Why this verdict

The profile lists the relevant limitation: intake was measured using 24-hour dietary recalls, which are subject to recall error and day-to-day variability in intake. This matches the story’s caveat.

Study evidence

Total coffee consumption by weight was stable from 2003 to 2018 (373 to 378 g/day; difference 4.49 g/day; p=0.791 for trend).4.49 g/day (p=0.791)

What the story left out

Important study details the story did not include.

Coffee-addition composition by weight in 2017–2018: dairy milk was the most common addition by weight, followed by non-dairy creamer and sugar.
The story focuses on calories added to coffee and does not report the distinct by-weight ranking, where dairy milk—not non-dairy creamer—is largest.
From Serial cross-sectional NHANES analysis
Reported sociodemographic differences: higher total coffee consumption was observed among men, non-Hispanic White adults, and individuals with higher income.
The story does not report the subgroup differences actually present in the abstract-level profile. Instead, it reports sleep, working-hours, and diet-quality comparisons that are not verifiable from the supplied abstract profile.
From Serial cross-sectional subgroup comparisons (NHANES)
Limitation: serial cross-sectional NHANES cycles describe population-level trends and do not track within-person changes over time or establish causality.
The story mentions recall-related measurement error but does not acknowledge that the design is serial cross-sectional and therefore cannot show that the same individuals changed their coffee habits or establish causal determinants of higher coffee energy.

5 things the story did carry across

Study design and data source: serial cross-sectional analysis of NHANES 2003–2018, using 24-hour dietary recalls from U.S. adults aged 20+ years, n=30,459, with survey-weighted analyses.
Main trend finding: total coffee consumption by weight was stable from 2003 to 2018 while energy from total coffee increased from 43 to 60 kcal/day.
Coffee-addition energy ranking in 2017–2018: non-dairy creamer contributed the most energy, followed by sugar and dairy milk.
Paper attribution: the increase in energy from coffee over time was primarily attributed to increased consumption of non-dairy creamer.
Limitation: 24-hour dietary recall intake measures are self-reported and subject to recall error and day-to-day variability.

3secondary dataDescribe sociodemographic differences (sex, race/ethnicity, income) in total coffee consumption in the NHANES adult population.Serial cross-sectional subgroup comparisons (NHANES)Expand

In plain English

Using data from eight cycles of NHANES (2003–2018; n=30,459 adults ≥20 y), the authors report that total coffee consumption was higher among men, non-Hispanic White adults, and individuals with higher income compared with their counterparts. Intake was derived from 24-hour dietary recalls and between-group comparisons used survey-weighted ANOVA and linear regression. The abstract does not provide subgroup-specific estimates or details on covariate adjustment in these comparisons.

Key findings

Higher total coffee consumption was observed among men, non-Hispanic White adults, and individuals with higher income compared with their counterparts (as stated in the abstract).

“Higher total coffee consumption was observed among men, non-Hispanic White adults, and individuals with higher income compared with their counterparts.”

What this piece can’t prove

Dietary intake based on 24-hour recall(s) subject to measurement error and day-to-day variability.
Cross-sectional design (NHANES cycles pooled) limits causal inference about determinants of higher coffee consumption.
Potential for residual confounding if subgroup analyses were not fully adjusted (not described in abstract).
