Blueberries Can Help Maintain Brain Function and Improve Memory
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 (23Trusted Source, 24Trusted Source).
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 (25Trusted Source).
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).
The antioxidants in blueberries seem to benefit your brain by aiding brain function and delaying mental decline.
Anthocyanins in Blueberries May Have Anti-Diabetes Effects
Blueberries provide moderate amounts of sugar compared to other fruits.
One cup (148 grams) holds 15 grams of sugar, which is equivalent to a small apple or large orange (1).
However, the bioactive compounds in blueberries appear to outweigh any negative impact of the sugar when it comes to blood sugar control.
Research suggests that anthocyanins in blueberries have beneficial effects on insulin sensitivity and glucose metabolism. These anti-diabetes effects occur with both blueberry juice and extract (27Trusted Source, 28Trusted Source, 29).
In a study in 32 obese people with insulin resistance, two blueberry smoothies daily caused major improvements in insulin sensitivity (30Trusted Source).
Improved insulin sensitivity should lower the risk of metabolic syndrome and type 2 diabetes, which are currently two of the world’s biggest health problems.
Several studies demonstrate that blueberries have anti-diabetes effects, improving insulin sensitivity and lowering blood sugar levels. ufabet
