In an interview in this week's "TV Guide", Bourdain calls Paula Deen "the worst, most dangerous person to America" for her artery-clogging style of cooking.
"She revels in unholy connections with evil corporations, and she's proud of the fact that her food is f--king bad for you," Bourdain said of the Food Network star, who is famous for her butter-heavy recipes.
"I would think twice before telling an already obese nation that it is OK to eat food that is killing us," Bourdain wrote.
"Plus, her food sucks."
Moving on, Bourdain leveled some scathing criticism on Food Network star and talk show host Rachael Ray.
"Does she even cook anymore?" Bourdain asked.
"I don't know why she bothers," he wrote.
"To her credit, she never said she was good at it. I feel bad that she still feels compelled to cook."
Bourdain, host of the Travel Channel's "No Reservations," says the downside of traveling around the world eating amazing food for the show is that he misses seeing his wife and daughter.
