When I was a child, the "elders" in my family always advised eating fish, saying it was "brain food." Not caring much for fish in those days, I brushed their comments aside. But, as with so much, they were on the right track. Each year, more and more information appears-- confirming the importance of diet in the way we think and feel. Its effects are far greater than one might imagine. They even extend to the reduction of aggression.
For example, researchers at Radboud University in the Netherlands conducted a study of 221 prisoners, ages 18 to 25. Of that group, 116 were given daily supplements containing vitamins, minerals and omega-3 for one to three months. The other 105 received placebos. Reports of violence and aggression declined by 34 percent among the group given supplements; at the same time, such reports among the placebo group rose 13 percent.
One doesn't have to go to the extremes of being in prison to consider the value of a healthy diet, particularly since so many children today eat so poorly. If you are interested, there is an excellent post which gives lots more information on this vital topic. You can find it at http://www.care2.com:80/greenliving/feed-your-brain.html
