The development of the human cerebral cortex has been linked with multigenerational consumption of oily fish containing essential fatty acids, in particular, DHA and EPA. A decline in proportionate consumption over the last century correlates with the marked rise in lifestyle-diseases, and perhaps even a dumbing-down of the population. Without essential fatty acids (DHA and EPA), humans fall prey to a host of debilitating and lethal chronic diseases, including the big C.
Our focus today is on two long chain Omega-3 essential fatty acids known as EPA and DHA. They are essential because our bodies can’t manufacture them so we must obtain them exogenously, i.e. in our food (1). And when we don’t get them, we're in a whole lot of trouble.
