What is the importance of food in Siddhartha the novel?

The truth is we are slaves to our own bodies. Food, Water, and sleep are necessary to our survival. Without those three we would die. In the Buddhists teachings they proclaim that one must shed their physical state in order to obtain enlightenment. So, in that case, one most deprive the body of what it depends on, such as food, water and sleep. Food represents the limitations of a physical existence, which seeks to distract one from the ability to achieve nirvana.
