Espresso coffee prevents Alzheimer’s tau protein clumping in lab tests

Whether enjoyed on its own or mixed into a latte, Americano or even a martini, espresso provides an ultra-concentrated jolt of caffeine to coffee lovers. But it might do more than just wake you up. Research now published in the Journal of Agricultural and Food Chemistry shows that, in preliminary in vitro laboratory tests, espresso compounds can inhibit tau protein aggregation—a process that is believed to be involved in the onset of Alzheimer’s disease.
