There is another feather in the coffee cap proposed by a study by Florian Koppelstatter, University Hospital Innsbruck & colleagues which says that drinking a cup of coffee with 100 mg caffeine can boost short-term memory.
The sample and procedure for the study involved 15 healthy men aged 26 to 47. Participants were tested when they consumed 100 mg caffeine and then when they consumed a placebo. 100 mg caffeine can be found in two cups of regular coffee.
AdvertisementThe tools used for the study were functional magnetic resonance imaging (MRI) to scan the brain, and memory test to see how the subjects respond with and without caffeine. The results showed that on coffee ingestion word recall and the memory test also indicated the improvement of short-term memory. Moreover, the participants after using caffeine responded to researchers' questions faster, meaning they were more attentive.
According to Dr. Koppelstatter, the current study did not suggest that people should rush to gobble too much coffee for the sake of memory improvement.
Although the mechanism of how caffeine affects memory and other health conditions is not clear, coffee is one of the most popular beverages worldwide. Caffeine, a naturally occurring stimulant, is mainly found in coffee, tea, soft drinks and chocolate. Further research is needed to ascertain the effectiveness of the study.
