The Chinese widely believe that we are what we eat, and most dietary guidelines follow nature's lead. According to Chinese Medical theory, eating with the seasons and following an energetically balanced meal plan allows us to remain in harmony with the environment, adapt better to changes in season and stay healthy. Chinese dietary therapy has been in practice for nearly a millenia in China and this tenet of Chinese medicine includes not just what you eat but how it was prepared, when and how you eat your meals as well as how these foods interract with each other over the course of the day.
An early medical writer and court physician of the Tang dynasty, Sun Si Mao, wrote in the 6th century, "A true doctor first finds out the cause of the disease, and having found that out, he tries to cure it first by food." Similarly, Hippocrates, an ancient Greek physician wrote, "Let your food be thy medicine and medicine be thy food."
Modern science has only recently begun to discover and research what has been a part of traditional medicine and culture for millenia - the importance of a balanced, varied diet comprised of natural, whole foods.
