Scientists at Birjand University of Medical Sciences in Iran conducted a large-scale analysis of studies showing that cinnamon and its derivatives can potentially improve memory and learning outcomes in adolescents. Findings published in the journal Nutritional Neuroscience.
Cinnamon is derived from the inner bark of an evergreen tree native to the Himalayas, China, India, and Southeast Asia. Studies show that cinnamon has anti-inflammatory, antioxidant and anti-cancer properties. Some studies have also shown that the biologically active compounds in cinnamon can improve brain function, particularly memory and learning. In the new study, the researchers decided to assess the validity of these findings.
The review authors found 2605 studies as of September 2021. Of these, 40 were of sufficient quality to be included in further analysis. Most of the work was done on animals or humans, others on cells and tissues.
Scientists have confirmed that according to studies, cinnamon can positively affect both memory and cognitive functions of teenagers who chew cinnamon gum. For adults, the evidence of efficacy was increasingly less convincing.
In addition, it has been shown in vitro that the addition of cinnamon or cinnamic aldehyde to the cell medium can reduce tau, beta-amyloid aggregation and increase cell viability.
The authors noted that more research is needed to draw conclusions about the effect of cinnamon on cognitive function.
