Cinnamon improves memory and learning ability.

Iranian researchers conducted a meta-analysis of 40 scientific papers that focused on the health effects of cinnamon. Most of them reported positive effects of the spice on learning and memory. Most likely, such components of the substance as cinnamic acid, eugenol and cinnamaldehyde bring benefits. The addition of cinnamon to the cell environment, for example, increases cell viability and reduces protein aggregation associated with Alzheimer's disease.
