Bethenny Frankel is one of the few Real Housewives who seems to have capitalized effectively on her position in the show, turning her Skinny Girl Margarita mix into a successful brand. At least, it was until recently. Whole Foods has yanked it form the shelves. According to the New York Post:

Whole Foods has stopped selling former “Real House wives of New York City” star Bethenny Frankel’s Skinnygirl Margarita after discovering it has potentially carcinogenic in gredients.

The drink — which Frankel crows on her Web site is “the margarita you can trust” with “all natural ingredients” and “no preservatives” — actually contains the preservative sodium benzoate, sources said.

Studies have found that the preservative can become carcinogenic if mixed with other substances such as vitamin C.
