Jung's comment, "The unconscious mind of man sees correctly even when the conscious reason is blind and impotent", is indicative to Margaret Atwood's book The Edible Woman. We see how the unconscious affects a woman mind unknowingly. The mind and body have an inter connection. They work with each other even though the conscious mind may not know it. .
Atwood's main character, Marian McAlpin, was ordinary. After she graduated college she started her simplistic job. Her relationships with people, friends, and her boyfriend, were purely surface. She began feeling crippled by the mundaneness of her already mapped out life. She feared the thought of being the annoying old lady in the basement. She feared living a married life with children, miserable like Carla. She feared the very thought of the "pension plan" for it symbolized the future. A future she hadn't began to question until she met Duncan. We see a shift of characteristics between Duncan and Marian. Her job is to chew up words to make it easier for people to read and understand and then test these people with her revisions. Duncan, however, treats the test as a psychological evaluation ex amplifying that one should think and question what is simplistic. This is what Marian begins to do. .
She needed to escape the thoughts that resided in her unconscious mind. She feared being pinned down. We get images of this through out the book. Her thoughts of cannibalism represents her fear of consumption. Destruction. Peter erupts these feelings inside her. His proposal of marriage charged her with such irrational fear that her physical self started to react to her unconscious self. Her inability of eating animals was a major symbol of her not wanted to pin down life. This transgressed to not being able to eat vegetables, because they too seemed life like to her. One can argue that she was only able to eat pasta and beans because they are starchy and stiff.
