I read an article on a website about preparing for exams, and it stated that because the brain consists of 1/5 Omega-3 fatty acids, it is important to eat fish, so your brain will get better at communicating.

Being very skeptic about the statement I tried to search the Internet for more information on the topic, but I was unable to get a clear answer.

Is it really true that the human brain consists of that much fatty acid, and if yes, is all of it Omega-3?

The brain doesn't have 20% lipids of any kind. So no, it's not true.

    If you discount water, it contains nearly 50% lipids.

    @Adam, I agree, but that isn't what he asked. I can't tell if it's what he meant; I can only see what he wrote.
