Whole Foods will no longer carry Dean Foods’ Silk Soy milk–instead goes with organic brands.

Last year, Silk Soy–while continuing to offer a somewhat higher-priced organic option–pushed the majority of its soy milk to “natural” (the beans still weren’t genetically modified [GMO], which is great).

It was a blow to the green movement–and one that changed Silk, overnight, from the world’s largest organic brand into, well, not.

Recently, I interviewed my friends at the Dean Foods-owned White Wave/Silk Soy about their decision to go “natural.” To their credit, they were open about the up- and downsides.

Silk, started by one of Boulder, Colorado’s natural products titans, Steve Demos, and now owned and controlled by mega-corp Dean Foods, was just dealt what must come as a pretty big blow–they’ve been cleaved from their strongest customer base–the conscious consumers who built Silk, back when it was owned by Mr. Demos, into a major player and first real alternative to milk.
