A recent medical study conducted at Cincinnati University in the United States suggests that making blueberries a daily dietary habit in middle age may assist in preventing cognitive decline associated with aging, thereby reducing the risk of dementia.
The same research team previously highlighted in 2022 that consuming blueberries regularly could contribute to insulin resistance, providing benefits not only for metabolic health but also for brain function.
According to the study, individuals who incorporate blueberries into their diet may experience improved memory and metabolic health. Researchers attribute these benefits to the presence of anthocyanins, antioxidants found in both blueberries and bilberries, which are beneficial for metabolism and brain health.
The research involved 30 individuals aged between 50 and 65, who reported initial signs of mild cognitive decline. Half of the participants were given a daily supplement of blueberries for 12 weeks, while the remaining individuals received a placebo. The participants underwent cognitive tests, insulin resistance assessments, and cholesterol level tests at the beginning and end of the study.
Results indicated that those who consumed blueberry supplements showed enhanced cognitive functions, reduced symptoms of depression, and improved memory compared to those who received the placebo. The researchers emphasized that daily intake of blueberries might reduce the risk of cognitive decline associated with aging.
The study highlights the potential cognitive benefits of blueberries and bilberries, linking their regular consumption to improved brain function and overall metabolic health. While the researchers acknowledge the need for further research to solidify these findings, the results provide promising insights into maintaining cognitive health as individuals age.
The findings of this research were published in the journal “Nutrients.”
