When you consider that 60% of your brain is composed of fat, you can begin to imagine that the kind of fat you eat will effect its composition.
After all, you now know that not all fats and oils are equal. And the composition of the membranes that surround your neurons will influence their function, because the more fluid the membrane is, and the more of the correct EFA are present, the faster the electrochemical impulse will move from neuron to neuron.
This is ultimately what thinking is about – an impulse that moves from neuron to neuron at lightening speed, approximately 200 miles per hour at best performance. When the membranes are deficient in the correct EFA then the way that the neurons respond to impulses will be influenced.
The synapse, which is the area where neurotransmitters are released to bind to the synapse of the next neuron in the sequence of thinking, is also rich in fats and oils, and once again, if they are the fluid, responsive EFA, then the synapses will be able to respond optimally.
If your diet is deficient in these EFA your thinking will be influenced negatively. Certain researchers have believed for decades, and been very vocal among their peers, about how the changes in our diets will influence our mental health in a very negative way. And the rates of mental illness have increased. Our diets have evolved to exclude the very fats and oils that are necessary for optimal physical and mental illness.
