Something has been revealed about blueberries, which is why it's worth eating them every day

Researchers from Harvard University studied the effects of blueberry consumption on depression symptoms in older adults. The small study involved 18 participants aged 65 and older, who consumed either freeze-dried blueberry powder or a placebo for three months. Results showed improvements in depression symptoms for both groups, with the blueberry group experiencing greater but statistically insignificant changes. Additionally, changes in gut microbiota were observed, particularly in bacterial enzymes related to gamma-aminobutyric acid, linked to depression. While the findings are preliminary, they suggest potential benefits of blueberries for mental health, warranting further research.
