Blueberries Improve Memory? Recently, the University of
Reading and the Peninsula Medical School in the Southwest region of England
conducted studies on the flavonoid compounds in blueberries. They
discovered that “phytochemical-rich foods are effective at reversing
age-related deficits in memory according to a published journal from Free
Radical Biology and Medicine.” (The Peninsula College of Medicine and
Dentistry, 2008) The study was conducted over a 12-week period. Multiple memory
tests were applied during those weeks, and within three weeks, memory
improvements were being documented. These improvements continued throughout the
duration of the 12 week test.
Blueberries contain anthocyanins and flavanols. It has been shown that these
particular molecules have the ability to cross the blood brain barrier after
consumption. The theory behind these molecules results in “enhancing
existing neuronal (brain cells) connections, improving cellular communications
and stimulating neuronal regeneration." (The Peninsula College of
Medicine and Dentistry, 2008)
“The research team was able to show the ability of flavonoids to induce memory
improvements are mediated by the activation of signaling proteins via a
specific pathway in the hippocampus, the part of the brain that controls
learning and memory.” (The Peninsula College of Medicine and Dentistry, 2008)
Many doctors involved in this scientific research project have successfully
documented that certain molecules present in blueberry consumption can benefit
memory. Dr. Jeremy Spencer was noted stating that, “[We] plan on extending our
research and plan on further investigating the effects of diets rich in
flavonoids on individuals suffering from cognitive impairment and Alzheiner’s
disease.”
