Diet and the evolution of the brain: Fish and no chips

Sounds like this DHA is pretty important for brain growth and evolution. The lack of it in modern diets and the change in brain chemistry that the lack causes—may be why there has been a big increase explains the growth in recent times of depression, manic-depression, memory loss, schizophrenia and attention-deficit disorder. And may be why we are seeing heavier and heavier people. Some good sound data to evaluate…

Discuss the many virtues of docosahexaenoic acid, the most important of that fashionable class of dietary chemicals, the omega-3 fatty acids.

DHA is a component of brains, particularly the synaptic junctions between nerve cells, and its displacement from modern diets by the omega-6 acids in cooking oils such as soya, maize and rape is a cause of worry. Many researchers think this shift—and the change in brain chemistry that it causes—explains the growth in recent times of depression, manic-depression, memory loss, schizophrenia and attention-deficit disorder. It may also be responsible for rising levels of obesity and thus the heart disease which often accompanies being overweight.
