I LOVE fermented foods (yoghurt, buttermilk, kefir, kombucha, kimchi, sauerkraut, etc.) and have seriously been considering refining our diets (especially mine, Spencer's and Xavier's) based on the Body Ecology Diet.
Cultures for Health is having a great giveaway right now for free starters. I am psyched about entering. Go to Kelly the Kitchen Kop for details.
I already make our own yoghurt, cottage cheese, bread and most baked goods, so I am not worried about all the fermenting required by the diet. More later when I finally decide what I am doing.
