Why Research Says Older Adults Benefit From Eating Wild Blueberries Daily

As we get older, minding our brain health is essential to maintaining optimal cognitive function, which includes things like focus, memory, and reaction time.

Blueberries have long been considered a "superfood," rich in antioxidants, vitamin C, phytoflavinoids, potassium, and more. So for this study, researchers wanted to dig deeper into just how much blueberries can benefit the health of aging populations.

To do so, they rounded up participants between the ages of 65 and 80 and had one group consume a blueberry beverage that was the equivalent of roughly a cup's-worth of wild blueberries, while the other group consumed a placebo beverage. The participants drank their respective drinks for 12 weeks.

Throughout the course of the study, those consuming the true blueberry drink saw improvement in memory, improved accuracy on attention tasks, and even lower blood pressure. The same could not be said for the placebo group, who did not reap the same benefits.

As study co-author Claire Williams Ph.D., explains in a news release, "It's clear from this study that consuming wild blueberries is beneficial to cognitive function, as well as vascular health.

If you're looking to protect your brain as you age, blueberries are just one simple solution of many to ensure your brain gets the support it needs. Beyond your daily handful of wild blueberries, other nutrients like resveratrol, omega-3s, high-quality protein, fiber, and antioxidants are great things to incorporate more in your diet.

And don't discount the profound effect sleep hygiene2, staying active3, and challenging your brain4 can have on brain health overall as well. (All of these things have been found in research to improve cognitive function.)

Lastly—and lucky for us and our brains—there are lots of quality supplements available today for boosting brain health, like ones that include ingredients such as kanna, citicoline, and omega-3s.
