Your coffee habit may be heavier than you think, and the milk and sugar are not the main reason. A new analysis of what Americans put in their cups found that non-dairy creamer has become the biggest source of added coffee calories.
Researchers at Tufts University analyzed eight rounds of the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2018. The sample was nationally representative: about 30,000 U.S. adults age 20 and older, each of whom described what they ate and drank over two 24-hour periods. The work appeared in the Journal of the Academy of Nutrition and Dietetics.
What the Study Found
People drank about the same amount of coffee throughout, roughly 13 ounces a day. But the calories in that coffee climbed from about 43 to about 60 per day, an increase of nearly 40%.
The change came mostly from non-dairy additions. Non-dairy creamer went from about 3.4 grams a day to 8, and non-dairy milk from 0.3 grams to about 2.5. Dairy milk, sugar and sugar substitutes showed no statistically significant change.
By 2018, dairy milk was still the largest addition by weight, at about 21 grams a day. But creamer was denser: it added roughly 18.5 calories a day, ahead of sugar at 16 and dairy milk at 11. Lead author Yongyi Pan noted that non-dairy creamers can be high in saturated fat, which is calorie dense.
What This Means for Your Cup
Sixty calories a day is not a crisis. The point is that the additions people think about least can add the most. If you drink several cups, the numbers multiply. Practical checks include:
- Read the label for the serving size. Creamer servings are often a tablespoon, and many pours are bigger.
- Measure your usual pour once. It takes a minute and shows what you actually use.
- Compare the calories and saturated fat on a few creamers, since they vary widely by brand.
- If you want to cut back, try a smaller pour first rather than switching everything at once.
The Catch
This is an observational analysis, so it shows trends, not cause and effect. The data rely on people remembering what they consumed, and a single day of eating does not always reflect usual habits. Ingredient amounts in pre-mixed drinks and powders were estimated from federal food databases. The idea that saturated fat explains the calorie rise is the authors’ interpretation, not something the study tested. The study also did not examine health outcomes, so it cannot say whether the extra calories affected anyone’s health.
The researchers also found that people who slept fewer hours or worked longer hours tended to drink more coffee, a reminder that the cup is often part of a bigger routine.
