Could eating blueberries every day improve reverse cognitive decline in elderly people?


According to a recent study, consuming blueberries daily may help reverse cognitive decline in elderly individuals. The University of North Carolina conducted research on the benefits of this superfood for those suffering from cognitive problems.

The study analyzed data from 86 individuals aged 65 to 80 who had cognition issues, as well as 43 individuals in the same age group who did not have cognitive decline, acting as a control group.

Participants were divided into two groups, with one group given a wild blueberry powder to add to their diets while the other received a placebo. The study used blueberries grown in Maine, which are known to be a strong source of phytochemicals. Phytochemicals are compounds that plants produce to defend themselves from environmental stress, fungi, bacteria, and viruses. Once ingested by humans, these compounds transfer health benefits to us. After six months of consuming the blueberry powder daily, participants' cognitive health was reevaluated. Those who had consumed blueberries had significantly improved mental processing speed.

The study's authors Dr Mary Ann Lila, noted that the specific phytochemicals found in wild blueberries are essential for brain health. Processing speed is a good indicator of overall brain health as it demonstrates how well information is being stored and recalled.

While there is currently no cure for dementia, a healthy lifestyle, including consuming blueberries, may help reduce the risk of cognitive decline. Blueberries are known to have high concentrations of antioxidants, vitamins, and minerals, making them a superfood.

Other similarly coloured fruits, such as purple grapes or blackberries, may also have a similar impact on reversing cognitive decline. Although the study was relatively small, it could provide insight into a potential solution for cognitive decline. There are no known downsides to incorporating blueberries into an elderly person's diet, and even small amounts may prove beneficial. Blueberries can be easily added to smoothies or other foods. Further research is needed, but this study suggests that blueberries may be an effective way to improve cognitive health in elderly individuals.
