Gwyneth Paltrow Elimination Diet: How Healthy Is Her New Cookbook?

"It's All Good," promises Gwyneth Paltrow in the title of her new cookbook, the second she has ever penned. But her recipes, based on a restrictive "elimination diet," which she claims helped her improve her health, have spurred a slew of comments and bashful criticism to her suggested lifestyle.

The book is a collection of 185 dishes that, with no exceptions, lack sugar, caffeine, dairy, meat, wheat and corn. According to Paltrow, the diet was prescribed by her doctor after she fainted during a picnic from what she thought it was a stroke. It turned out to be a migraine. They found she was anemic and vitamin-D deficient.

"After changing my diet, I healed totally, felt more energetic and looked great," states the introduction to the book.

The actress went so far as to say that her children do not eat pasta, bread or rice. And she admitted that in a way they are "left with that specific hunger that comes with avoiding carbs." According to the lifestyle guru, everybody can benefit from a wheat-free diet, adding that "all nutritionists say that human beings are intolerant to gluten at best, and allergic at worst."

However, nutritionists are actually expressing worries about a full on carb-voiding diet.

"Cutting carbs from kids is extreme. Limit them by all means, but demonizing carbs is a naïve step that doesn't help anyone," said Dr. Ian Marber.

"My advice is to get carbohydrates from other sources, like quinoa or sweet potatoes," added Dr. Kim Pearson.

The book does not come out until April 2, but critics are already deeply divided on their take of Paltrow's so-called healthy diet. Food blog Eater.com published a merciless review of Paltrow's first cookbook "My Father's Daughter," calling it a "vanity project from a rich person completely unafraid to casually boast about her life of privilege," and assures that the sequel will "continue down this path of faux-populism and rich person dietary condemnation."

Publisher's Weekly, on the other hand, called it "a warm and inviting collection, filled with charming personal anecdotes."

"It's All Good" will come out as both an e-book and hardcover by Hachette Book Group.
