Fish is brain food
Although these fatty acids can be synthesised in the human body from food-derived shorter chain
omega-3 fatty acids, it is more efficient if they are eaten in their long-chain form. It is possible that
at the time of rapid brain growth early in life there may be a special requirement for omega-3 fatty
acids. National nutrition committees are now looking at whether, like other nutrients, there should
be Recommended Dietary Intakes (RDIs) of omega-3 fatty acids, at least for children.
Another interesting aspect of this story is that, in evolutionary terms, we probably emerged at the
water's edge and have lived by the water. Thus, fish or shellfish consumption has been an integral
part of traditional food habits.
