While not everyone loves cinnamon, this new study may convince skeptics. Previous studies have already given this spice anti-inflammatory propertiesantioxidants and anti-cancer.
A team of researchers from Birjand University of Medical Sciences (Iran) recently reviewed several previous studies exploring the effects of cinnamon on cognitive functions. Scientists have highlighted the interest of cinnamon for prevent or reduce memory impairment or learning.
The scientists reviewed hundreds of studies stored in several online search databases, including PubMed, Scopus, Google Scholar and Web of Science. They then narrowed their analysis down to 40 of these studies, those that were most relevant to their topic of interest. Of these 40 studies, 33 were performed in vivo, five were conducted in vitro and two were clinical studies.
Improve cognitive function
“In vivo studies have shown that the use of cinnamon or its components, such as eugenol, cinnamaldehyde and cinnamic acid, can positively alter cognitive function“, wrote the researchers. Before completing: “In vitro studies have also shown that the addition of cinnamon or cinnamaldehyde to a cell medium can reduce the aggregation of tau, amyloid β and increase cell viability” .
Of the two clinical studies analyzed by the researchers, one was conducted on adolescents and the other on pre-diabetic adults. The first study had teens chew cinnamon gum, while the second had participants eat 2 grams of cinnamon on white bread. Cinnamon chewing gum has been found to improve memory function and reduced anxiety. In pre-diabetic adults, no changes were identified. “Most studies have reported that cinnamon may be helpful in preventing and reducing impaired cognitive function,” the researchers wrote in their paper. “It can be used as an adjuvant in the treatment of related diseases. However, further studies should be conducted on this subject”.
