Scientists Compared Frequent and Occasional Coffee Drinkers—a Trend Emerged
Summary
A study of 61 healthy adults found that frequent coffee drinkers had more diverse gut microorganisms, lower acidity readings in the small intestine, and an association with more frequent colon contractions. The researchers said the study cannot show that coffee caused these differences, and the effects of the lower pH remain unclear.Key Facts
- Researchers at the University of Copenhagen studied 61 healthy adults over nine consecutive days.
- Participants recorded their food and drink intake for eight days, and researchers assessed coffee intake using those records and caffeine-related substances in urine.
- The researchers classified participants as frequent drinkers if they consumed one to five cups on more than three of the eight recorded days.
- Fifty participants swallowed a wireless capsule that measured digestive transit time, temperature, acidity, pressure, and intestinal contractions.
- Frequent coffee drinkers had greater gut microorganism diversity than occasional drinkers.
- Frequent coffee drinking was associated with lower pH in the small intestine and more frequent colon contractions.
- Researchers said they could not establish whether the lower small-intestine pH was beneficial or harmful.
- The study found associations and did not prove that coffee directly caused the observed differences.
