In other words, may some foods be specifically good for brain function?

For a great in-depth review of the effects of food on the brain you can check out Fernando Gomez-Pinilla’s recent article in Nature Reviews Neuroscience (reference below). Here is an overview of the state off the research.

Several components of diet seem to have a positive effect on brain function.

Omega-3 fatty acids

These acids are normal constituents of cell membranes and are essential for normal brain function. Omega-3 fatty acids can be found in fish (salmon), kiwi, and walnuts. Docosahexaenoic acid, or DHA, is the most abundant omega-3 fatty acid in cell membranes in the brain. The human body produces DHA but not enough. So we are dependent on the DHA that we get from what we eat.

A randomized double-blind controlled trial (which means seriously conducted scientific study) is currently looking at the effect of taking omega-3 fatty acids on children’s performance at school in England. Preliminary results (Portwood, 2006) suggest that Read the rest of this entry »
