Coffee Calories Are Up Nearly 40 Percent: Why Non-Dairy Creamer, Not Sugar, Is the Culprit

Here is a statistic that will not make your morning easier: Americans are drinking roughly the same amount of coffee as twenty years ago, yet the calories in their cups have risen by nearly 40 percent. The usual suspect, sugar, has an alibi. According to a new analysis from Tufts University, the biggest calorie source added to coffee is now non-dairy creamer.

Agent Dale Cooper in Twin Peaks famously praised a “damn fine cup of coffee”. He took it black. The rest of us, it turns out, have been quietly turning the cup into something closer to a dessert.

What the Tufts study found

The research team at the Friedman School of Nutrition Science and Policy at Tufts analysed data from the National Health and Nutrition Examination Survey (NHANES), a long-running US government survey. The study covers eight survey cycles from 2003 to 2018 and about 30,000 adults aged 20 and older, each of whom reported everything they ate and drank over two separate 24-hour periods. The paper appears in the Journal of the Academy of Nutrition and Dietetics; Tufts announced it on October 20, 2026.

The headline numbers are simple. Average coffee intake stayed at about 13 ounces a day, a little under 400 millilitres. Calories from coffee and its additions climbed from 43 to 60 kilocalories a day. The amount of dairy milk and sugar people added did not change significantly over the period. What did change was everything that is not dairy: non-dairy additions rose from 3.65 to 10.5 grams a day. Non-dairy creamer alone went from 3.37 to 8 grams a day, while plant-based milks rose from 0.27 to 2.45 grams.

By 2018 non-dairy creamer delivered 18.5 kilocalories a day to the average coffee drinker, up from 7.71 in 2003. That put it ahead of sugar at 16 kilocalories plus dairy milk at 11. “Non-dairy creamers can be high in saturated fat, which is calorie dense,” lead author Yongyi Pan said in the university’s announcement.

Creamer is not the same as oat milk

Before you throw your barista oat milk out of the fridge, one distinction matters. The study separates non-dairy creamer from non-dairy milk. Creamers are the flavoured liquids and powders sold specifically for coffee, the kind with names that sound like a scented candle. Plant milks such as oat, soy or almond drinks are a separate category. Their use grew from a very low base.

The bigger calorie jump comes from creamer. Pan suggested a plausible reason: many consumers reach for it while looking for plant-based or dairy-free alternatives. That is a neat example of a health halo, the effect where a product feels lighter because of what it leaves out (“no dairy!”) rather than what it contains. A product can be free of lactose and still rich in fat and sugar. The label on the back usually tells you more than the word on the front.

What 17 extra calories really mean

Seventeen kilocalories a day does not sound dramatic. It is roughly the energy in one teaspoon of sugar. But small daily habits add up: over a year, 17 extra kilocalories a day come to around 6,200. That is our own back-of-the-envelope calculation, not a figure from the study. It is also an average across all adults. Someone who drinks one black espresso adds nothing; someone with three large mugs and a generous pour of hazelnut creamer adds far more.

Nutrition experts often point out that liquid calories are easy to overlook because they do not fill you up the way food does. UK nutritionist Rashmi Gajree, who was not involved in the research, told Newsweek that non-dairy creamers are not inherently bad in moderation and that their value depends on the ingredients. “Small swaps could be a simple place to start,” she said.

The researchers also noticed a pattern that will sound familiar to anyone who has survived a deadline week: adults who slept less or worked longer hours drank more coffee. Coffee intake was similar across people with healthier and less healthy overall diets.

The limits of the data

Two caveats deserve attention. First, the data rely on what people remember and report about their own eating, which always involves some error. Second, the study ends in 2018. That is before the pandemic reshaped many people’s home routines, including how they make coffee. Whether the trend has continued, slowed or accelerated since then is not answered by this study.

There is also a nice piece of timing in the data. The analysis starts in 2003, the year Starbucks introduced its Pumpkin Spice Latte. Nobody would blame a single seasonal drink for a national trend, but it is a fitting bookmark for two decades in which coffee shifted from a bitter wake-up call to a customisable lifestyle product.

So what should you do with your cup?

None of this means coffee is a problem. Senior author Fang Fang Zhang noted that coffee consumption has been associated with several health benefits. The point of the study is to understand what people actually add to it. If you are curious about your own habit, the simplest step is to read the label of whatever you pour in and to measure it once instead of eyeballing it. Unsweetened versions with short ingredient lists are one option; a dash of cinnamon is another, as Gajree suggested.

The study is less a warning than a mirror. Coffee has become one of the most personal rituals of the day, complete with its own aesthetics, flavours and identity. The cup is still the same size. What we put in it says more about modern food culture than about the beans themselves.
