“I will never shop there again,” vowed Joshua, a 45-year-old blogger, who asked that his last name not be published.

Like many of his fellow health food fanatics, Joshua said he will no longer patronize the store after learning about Whole Foods Market Inc.’s CEO John Mackey’s views on health care reform, which were made public this week in an op-ed piece he wrote for The Wall Street Journal.

Michael Lent, another Whole Foods enthusiast in Long Beach, Calif., told ABCNews.com that he, too, will turn to other organic groceries for his weekly shopping list.

“I’m boycotting [Whole Foods] because all Americans need health care,” said Lent, 33, who used to visit his local Whole Foods “several times a week.”
