    Diet and Nutrition
    The acid-alkaline balance of our food is very important.  Foods that are
    pH-balanced will not corrupt quickly, and the eater will be able to extract
    the maximum amount of nutrition available from those foods.  If the food
    we eat is not pH-balanced, it becomes corrupt as soon as it enters the
    digestive tract.  The body, instead of benefiting from the nutrients in the
    food, absorbs the poisons resulting from the corruption.  If one goes to the
    back door of any restaurant, one will find food corrupting in garbage cans.  
    Not long ago, this food was served to customers.  So the only thing
    separating the front and back of the restaurant is a wall and a few hours'
    time.  We would not purposely eat garbage because we know we will
    become sick from ingesting poisons.  Yet, we do eat garbage every time
    we eat without a thought for pH balance.  A telltale sign of food corruption
    in the stomach is bad breath.  The Complete System of Self Healing, by
    Dr. Stephen T. Chang.
