We just finished a unit in school on alternative diets. I was really fascinated to learn about how Traditional Chinese Medicine (TCM) can play a role in our diets. It still kind of confuses me, but the general concept is that you eat cooling/raw (yin) foods in the summer, and warming/cooked (yang) foods in the winter. It really makes sense when you think about it, and I am definitely considering incorporating a more macrobiotic diet into my life for a while to see how my body likes it. I feel like it is my job, as a Holistic Nutritionist, to use myself as a guinea pig before ever recommending anything to clients.
Here is a link that explains this concept in more depth: http://macrobiotic.about.com/od/gettingstarted/a/YinYang.htm
