Piecing together how the human brain evolved is a bit of a chicken and egg conundrum-- a larger brain needs a larger amount of protein to evolve, but figuring out how to get this protein would apparently require a larger brain. That's where we think seafood comes in.
According to a study in The Journal of Human Evolution, a large amount of adult mollusk shells found in concentrated areas around a million-year-old hominid camp is evidence that our ancestors used the seafood found in small pools around their home to supplement their diet. They hypothesize that this supplement may have been the boost we needed to kick start our brain's evolution, making seafood the original brain food.
This may help explain why seafood is so good for our brains today, and why a study out of The American Journal of Preventive Medicine found that eating seafood at least once a week noticeably boosted brain volume while reducing the risk of Alzheimer's. If it worked for our ancestors, maybe it can work for us.
