health of the brain, and the nessessary componets in protecting against brain related diseases like
Alzheimer's and Parkinson's (Hall, 2011). Several parts of the brain initiates, and
maintains motivation that engages in healthy eating. Some researchers say that
evolutionary factors come into play. Factors like reinforcements of endorphins and serotonin activity

nervosa (University of Colorado, 2011). The amygdala allow us to recall previous learnings, and store
new habits like eating healthy. Human prefrontal cortex controls behavior, and proper decision making
toward food. There are additional structures of the brain that play a part in healthy eating such as;
mesolimbic opioid and dopamine discussed earlier initally increases the appetite for eating. However, an
increased appetite could be due to suffering from an injury to the hypothalamus, but study have shown
that vitamin E helps protect the hippocampus and the cerebellum. Food like almonds, spinach, sunflower
seeds and blueberries were considered rich in vitamin E, and could regulate signaling of neurons.

bigger bites. The hypothalmus regulates the evelutionary response to hunger and thirst. It can also
respond to changes in a diet (Stone, 2011). This leads back to dopamine, an evolutionary perspective
would be that the dopamine system is what promotes pleasure for survival activites such as: eating,
drinking, and sex (Stone, 2011). inevitably individuals are motivated to behavior were dopamine is
released. If a person is on a set diet, difficulty with the...
