A new study says a daily cup of coffee could ward off dementia, adding to the litany of often contradictory findings about the popular drink.

30-Second Summary

A study by a team of researchers for the Journal of Neuroinflamation reported that when rabbits were given a caffeine supplement, “a vital barrier” between the brain and the main blood supply was protected from the dementia-causing damage cholesterol can inflict.

The experiment showed that the equivalent of one cup of coffee a day was enough to yield the benefits.

The barrier “is a filter which protects the central nervous system from potentially harmful chemicals carried around in the rest of the bloodstream,” reports the BBC.

Previous studies have tied caffeine to a lower risk of Alzheimer’s disease, and this new study may explain why.

But conflicting reports make coffee a tough drink to figure out.

Coffee has been linked to a range of health problems, including miscarriage and diabetes complications, but also to many health benefits, including protection of the brain and prevention of certain cancers, such as ovarian and liver cancer.

The consensus, according to most experts, is that moderate coffee consumption is safe, and possibly beneficial, so coffee fans can keep up the daily habit.
