Proven Health Benefits of Blueberries

Oxidative stress can accelerate your brain’s aging process, negatively affecting brain function.

According to animal studies, the antioxidants in blueberries may affect areas of your brain that are essential for intelligence (23, 24).

They appear to benefit aging neurons, leading to improvements in cell signaling.

Human studies have also yielded promising results.

In one of these studies, nine older adults with mild cognitive impairment consumed blueberry juice every day. After 12 weeks, they experienced improvements in several markers of brain function (25).

A six-year study in over 16,000 older individuals found that blueberries and strawberries were linked to delays in mental aging by up to 2.5 years (26).
