Which food is supposed to help in the prevention of dementia?

Blueberries are perennial flowering plants with amazing health benefits. Commercial 'blueberries', including both wild and cultivated blueberries, are all native to North America. The cultivated blueberry varieties were introduced to Europe last century.

Blueberries consist of 14% carbohydrates, 0.7% protein, 0.3% fat and 84% water. One serving provides a relatively low caloric value of 57 kcal per 100 gram (3.5 oz) serving. It also contains a glycemic score of 6 out of 100 per day, which is considered very healthy for diabetics.

Blueberries contain high polyphenolic compounds, which have antioxidant and anti-inflammatory effects. This antioxident has 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.

Due to the prevalence of dementia especially in our aging population, preventive approaches are essential to address this public health problem. There is no remedy for dementia, but dietary approaches hold promise as effective and safe preventive interventions.

Dietary factors represent the most potent determinants of metabolic health and have been shown to mitigate specific mechanisms of dementia. Polyphenol consumption is important in this regard, and epidemiological studies indicate that consumption of blueberries is associated with lower risk of neurodegenerative disorders and better cognitive performance in the elderly.
