It’s a favorite first-order for the day, but while a quick coffee may perk us up, new research from the University of South Australia shows that too much could be dragging us down, especially when it comes to brain health.

In the largest study of its kind, researchers have found that high coffee consumption is associated with smaller total brain volumes and an increased risk of dementia.

Conducted at UniSA’s Australian Centre for Precision Health at SAHMRI and a team of international researchers, the study assessed the effects of coffee on the brain among 17,702 UK Biobank participants (aged 37-73), finding that those who drank more than six cups of coffee a day had a 53 percent increased risk of dementia.

“Coffee is among the most popular drinks in the world. Yet with global consumption being more than nine billion kilograms a year, it’s critical that we understand any potential health implications,” Pham says.

“This is the most extensive investigation into the connections between coffee, brain volume measurements, the risks of dementia, and the risks of stroke — it’s also the largest study to consider volumetric brain imaging data and a wide range of confounding factors.
