Blueberries + exercise = healthy minds?

Blueberries + exercise = healthy minds?: At the molecular level, Joseph and his colleagues found that animals who ate blueberries, and to a lesser extent the other foods, had healthier-looking brains. In addition, the researchers found that the membranes of the rats' brain cells were more fluid and better able to move chemicals in and out, which, presumably improves how well the brain sends and receives signals. And, they have preliminary data showing that the chemicals that carry signals in the brain are better able to do their job.
