The role of fat in brain evolution

This was in a post on one of the diabetes lists I belong to, and I'm thinking this book might be a very interesting read.
I ran across this book today on Dr. Michael Eades blog, "Survival of the Fattest." Here's a description from the publishers...

"How did humans evolve larger and more sophisticated brains?

In general, evolution depends on a special combination of circumstances: part genetics, part time, and part environment. In the case of human brain evolution, the main environmental influence was adaptation to a ‘shore-based’ diet, which provided the world’s richest source of nutrition, as well as a sedentary lifestyle that promoted fat deposition. Such a diet included shellfish, fish, marsh plants, frogs, bird’s eggs, etc. Humans and, and more importantly, hominid babies started to get fat, a crucial distinction that led to the development of larger brains and to the evolution of modern humans. A larger brain is expensive to maintain and this increasing demand for energy results in, succinctly, survival of the fattest."

So if we hadn't acquired sufficient fat, who knows what we humans might have become? This is a far cry from what we usually hear!

It's an expensive book to buy, but if you are interested, you might find it in your library...

So what will this mean for all those fat babies that everyone thinks need to be put on diets and shouldn't be fat? Seems to me that babies need that fat to help their brains grow and develop and depriving them of their fat stores is going to stunt their brain growth and development. I don't think that is something this country needs - generations of children with smaller and less capable brains simply because some people think fat isn't aesthetically pleasing. Talk about cutting your nose off to spite your face - that's a case of epic fail right there, people.
