So whats the straight dope ?
A long time ago fish was though of as “brain food.” Even some medical people fell for it, but that was a long time ago. P.G. Wodehouse wrote the Bertie Wooster-Jeeves series a long time ago. I seriously doubt that Wodehouse fell for it, but Bertie wasn’t the sharpest tack in the box by a long shot and he could have easily.
There are some sites that claim scientific studies showing that fish, because it provides some particular nutrients is good for fetal brain development. I found then by searchin [brain food + fish]. I’m not qualified to judge that but you can look them up yourself.
By the way, fish in some areas have a high concentration of mercury in their flesh as a result of industrial dumping in the past. I believe ingested mercury can lead to mental retardation and all sorts of other problems. Sort of like lead.
Some fish do contain a high concentration of omega-3, an essential fatty acid which is lacking in most people’s diets. It does have benefits for your brain, among other organs. There are a few other sources of omega-3 (eggs and nuts, I believe), but fish has the most (again, I think). That may have something to do with the belief in question.
Dear, me! For a second there I thought it said “does eating flesh make you smarter” and I started thinking it was a question on cannibalism.
There is an article here about some of the “fish=brain food” and a separate article talks about developing children, saying
On the other hadn, has Simmons pinted out, there is a lot of material out there warning women who are pregnant or breast feeding that fish that contain high level of mercury are harmful for baby/youngster development.
A list of “bad” fish for mommies can be found here.
Slight highjack - I read that fish eating nations have less baldness than meat eating nations. Certainly looks like it when I compare Japan and China with Australia and NZ.
Cold water fatty fish such as sardines, mackerel and salmon are the best sources of Omega 3 fatty acids, which aid in brain functioning. Flax seed oil is also a very good source.
Yes oily fish is good for brain developement, particularly IQ. I’m a bit bemused by David Simmons’ post as he appears to be very sceptical.
You need to get your essential fatty acids from somewhere. Fish is a good choice.

IMPORTANCE OF n-3 FATTY ACIDS IN HEALTH AND DISEASE
There doesn’t seem to be any well defined mental deficiency disorder associated with lack of these EFA’s in adults, but other problems do arise:
•Coronary heart disease and stroke
•Essential fatty acid deficiency in infancy (retina and brain)
•Autoimmune diseases such as lupus and rheumatoid arthritis
•Crohn’s disease
•Cancers of the breast, colon, and prostate
•Mild hypertension.
I am extremely skeptical that eating fish makes you smarter in the sense that I think was meant in the OP.

That sounds to me like, “Just eat fish and be smart.” And, as I said, I’m unable to evaluate the nutrion studies about the subject. It does sound as if the nutrients in fish will at least help to not get stupider.
It makes you smarter than the fish.
