Consumption of blueberries in middle age can prevent the development of dementia later, researchers say.
It turns out that berries contain a substance that helps the brain against Alzheimer's disease . Some experts believe that it is important to pay more attention to the benefits of a healthy diet.
Blueberries are a superfood that is associated with a reduced risk of developing heart disease and cancer.
Researcher Robert Krikorian of the University of Cincinnati in the United States studied 47 men and women aged 68 and older. They are diagnosed with mild cognitive impairment. This means that they suffer from minor memory gaps that often develop into dementia .
During the study, participants received a placebo or powder obtained from frozen and then dried blueberries , which they took for four months. One sachet of cranberry powder contains the equivalent of a teaspoon of cranberries.
Participants also underwent tests aimed at testing their mental abilities at the beginning and end of the study. These tests focus on the memory and thinking abilities that are affected by dementia .
Blueberries have been found to support the aging brain - there has been a significant improvement in cognitive function among those who consume blueberries. In addition, brain scans show that their brain is more active.
According to researchers, the benefits are due to the content of anthocyanins, which are plant substances. The blueberries owe their intense blue-purple color to them. They are thought to act on the brain in several ways - they increase blood flow, reduce inflammation and help transmit information between cells. These substances can also strengthen the defenses of cells.
