The folds and wrinkles of a walnut bring to mind another human organ: the brain. The shape of the nut even approximates the body part, looking like it has left and right hemispheres. And it's no surprise walnuts are nicknamed "brain food".
Eating Walnuts to Boost Brain Power
Researchers at Andrews University recently discovered the brain boosting power of walnuts. They divided 64 students into two groups. One group munched on banana bread made with walnuts every day for 2 months. The second group ate banana bread without walnuts for the same period of time.
At the end of the 8 weeks, they gave the students a variety of cognitive tests to measure their ability to think in different ways. They discovered the students who had eaten walnuts daily for 2 months performed better on tests that measured inferential reasoning. Inferential reasoning is the ability to judge the accuracy of statements made when reading an article, paper or other source.
