Chapter six explains that learning and how nurture can change us as people. One topic discussed is the myth that we are what we eat. In the 1950's, James McConnell put this to the test by performing an experiment on planaria worms. He trained the worms to scrunch their body under light by using an electric shock. Once the worms naturally scrunched under light without a shock, he cut them into tiny pieces and fed the trained worms to untrained planaira worms (disgusting, right). What he found is that these new worms reacted the same as the trained worms under the light, there-for solving the myth that we are what we eat, right?
Not so fast. Other psychologist were not able to replicate the same data and many believed that the light itself was the reason they scrunched up and not because the untrained worms ate the trained worms. McConnell argued his case all he could but it's clear why we should always think scientifically whenever possible.
In the end, neither a black or white answer has come about about whether or not we can chemically transfer memory. Many people had and still have McConnell's back such as Georges Ungar. He who believed "memories could be chemically transferred in mammals" (http://www.quasar.ualberta.ca). It is a very interesting topic but I do not see enough evidence in the matter to believe that we really are what we eat.

That was cool how the untrained worms scrunched under the light too. But i do have to agree that we are not what we eat.
