Summary

This study looked at whether drinking specialty coffee (a type high in a natural compound called chlorogenic acid) could improve memory, thinking speed, and attention in people with type 2 diabetes. Forty coffee drinkers with diabetes took part, drinking either specialty or regular coffee one week apart. Researchers tested their brain function before, 5 hours after, and 24 hours after drinking coffee.
