Beetroot consumption is suggested to improve blood flow to which area of the brain linked to higher-level thinking?
The prefrontal cortex
The cognitive benefits derived from beets are closely linked to the systemic improvement in circulation facilitated by nitric oxide production. This enhanced vasodilation affects blood flow centrally, reaching the brain. Specifically, studies focusing on cerebral circulation suggest that beetroot consumption can lead to an augmentation of blood flow directed toward the prefrontal cortex. This area of the brain is functionally critical, as it governs executive functions, including complex decision-making processes, working memory capabilities, and other facets of higher-level thinking. Increasing perfusion in this region via nitrate-induced NO production is associated with measurable improvements in cognitive performance, especially in older adults.
