Interesting that none of the recent articles and lists on 2012 food trends have mentioned biodynamics, although I have spotted the odd stand alone article. If you’re not familiar with biodynamics it’s roughly the idea that everything is part of a dynamic system, so it’s a little bit like organics, but taken to a much wider and deeper level.
The only problem with biodynamics as far as I can see, apart from the sense that it looks like a fad rather than a trend, are the astrological aspects of biodynamics, namely the fact that people should plant and harvest crops according to phases of the moon. This is not in itself totally nuts, but linking things to the 12 constellations of the zodiac sounds like it is.
