Travel Channel host Andrew Zimmern has made a name for himself devouring bizarre foods around the globe, but there’s one thing this gustatory daredevil can’t stomach. “A walnut will never cross my lips,” Zimmern told a crowd at the Chicago Theatre on Wednesday. He was part of a presentation to media buyers and advertising honchos about upcoming programs on the Travel Channel and its sister networks, including HGTV and Food Network. Zimmern’s “Bizarre Foods America” returns to the Travel Channel in July with new episodes, but don’t expect to see any walnuts. “They’re soapy,” he said in disgust.
