Chlorogenic Acid, Found in Coffee, May Improve Cognitive Performance, Motor Speed
You know coffee perks you up, but did you know it might make you smarter? A recent study suggests that a compound found in coffee, called chlorogenic acid, may help improve cognitive function and motor speed.
Participants in the study included 38 healthy people who were given either 300 mg of chlorogenic acids or a placebo daily for 16 weeks. The researchers used the Japanese version of the CNS Vital Signs (Cognitrax) to assess cognitive function.
The researchers found that the chlorogenic acid group had significant increases in the Cognitrax domain scores for motor speed, psychomotor speed, and executive function, when compared with the placebo group. They also showed improvement in the shifting attention test scores. Additionally, the chlorogenic acid group showed increased levels of apolipoprotein A1 and transthyretin. Low levels of both of these are considered biomarkers for early-stage cognitive decline.
Researchers from Kao Corporation in Japan led the study. It was published on September 20, 2018, in Nutrients.
In addition to coffee, chlorogenic acid is found in apples, pears, carrots, tomatoes, and sweet potatoes. It can also be taken in supplement form, as it was in this study.
