BALTIMORE, MARYLAND —A recent study conducted at Johns Hopkins University and published in the journal Nature Neuroscience found that caffeine could help boost long-term memory.
The study included 160 participants. In the beginning of the study the subjects were shown pictures of different objects and were asked to identify if they were “inside” or “outside” items. The group was then randomly split up into 2 groups; one group received 200 mg of caffeine and the other group received a placebo (not caffeine). The following day the participants were shown the same pictures as well as a few new ones, they were asked to identify whether the pictures were “new”, “old”, or “similar”
The team found that those who consumed at least 200 mg of caffeine were significantly better at identifying the correct images.
According to the study authors:
"Thus, we conclude that a dose of at least 200 mg is required to observe the enhancing effect of caffeine on consolidation of memory."
The main sources of caffeine can be found in coffee and green tea. However, it is recommended to consume no more than 2-3 cups of coffee per day.
If you are interested in boosting your long-term memory, you might want to consider adding caffeine to your daily diet.
Enjoy your day.
