Researchers in Spain recently published a study examining coffee consumption and cognitive functioning in older overweight adults (average age of 65). A total of 6427 volunteers were surveyed on their coffee and caffeine consumption and administered a battery of cognitive tests. The researchers found that increased coffee intake was associated with better performance on the cognitive tests. These results agree with previous work that indicates moderate caffeine consumption can improve cognition; however, it is important to note that, in addition to caffeine, coffee contains many chemicals that may impact cognition including polyphenols and melanoidins. This study reinforces the benefits of mild-to-moderate caffeine consumption on cognition in older adults.
