Bitter Brew: High Coffee Consumption Is Associated With Smaller Brain Volume:
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.
Lead researcher and UniSA PhD candidate, Kitty Pham, says the research delivers important insights for public health.
"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.
[...] "Accounting for all possible permutations, we consistently found that higher coffee consumption was significantly associated with reduced brain volume - essentially, drinking more than six cups of coffee a day may be putting you at risk of brain diseases such as dementia and stroke."
[...] "Typical daily coffee consumption is somewhere between one and two standard cups of coffee. Of course, while unit measures can vary, a couple of cups of coffee a day is generally fine.
"However, if you're finding that your coffee consumption is heading up toward more than six cups a day, it's about time you rethink your next drink."
