In a study from the University of Cincinnati, researchers found blueberry supplementation improves memory in older adults.
The prevalence of dementia is increasing with the expansion of the older adult population.
In the absence of effective therapy, preventive approaches are essential to address this public health problem.
Blueberries contain polyphenolic compounds, most prominently anthocyanins, which have antioxidant and anti-inflammatory effects.
In addition, anthocyanins have been associated with increased neuronal signaling in brain centers mediating memory function as well as improved glucose disposal, benefits that would be expected to mitigate neurodegeneration.
In the study, the team examined the effects of daily consumption of wild blueberry juice in a sample of nine older adults with early memory changes.
At 12 weeks, they observed improved paired associate learning and word list recall memory task.
In addition, there were trends suggesting reduced depressive symptoms and lower blood sugar levels.
The team also compared the memory performances of the blueberry group with a control group who consumed a berry placebo beverage and found results for the paired-associate learning task.
The findings of this study suggest that moderate blueberry supplementation can confer neurocognitive benefits.
