While we’ve found many nutrients that appear to help the brain,
they’ve got to be able to cross the blood-brain barrier, which few do.
One nutrient that does is blueberry. There was an exciting study
published in 2005, in Nutritional Neuroscience, in which the
researchers fed rats blueberries for 8-10 weeks. What they discovered
was that the phytochemicals actually crossed the blood-brain barrier
and lodged themselves in the areas of the brain responsible for
memory and learning.
Additionally, the greater the concentration of blueberry
phytochemicals in those areas, the better the rat’s cognition and
memory was found to be.
Another related study in the Journal of Experimental Neurology
showed that whenever there’s interrupted blood flow to the brain,
permanent damage results. However, rats receiving blueberries, along
with spinach and spirulina, were significantly less affected. The brain
is protected to an amazing degree with blueberries.

A similar study was conducted by Dr. James Fisher at Tufts
University in Boston. This was done on rats with a human equivalent
age of 70 to 75 years old. The dose of blueberries in human terms was
