If you enjoy food, brains, and lots of acronyms for various neuromodulating protein complexes then you will love this article. Actually, the thing that I like most about this article is that it condenses several complex studies of brain function into a few paragraphs that are relatively easy to understand. There are links included to several of these studies that quickly dive into complex neuroscience, but there are also several diagrams that help to visualize the basis for the conclusions of the article.
The take home message: Fat is bad, fatty acids are good. Go gettem! Enjoy a nice piece of fish whenever you are able to. Your brain will thank you.
