If Gwyneth Paltrow can't take the heat, maybe she better get outta the kitchen. Literally.

The 'Iron Man' actress penned a gluten and sugar-free cookbook entitled 'It's All Good,' but the critics seem to disagree.

In her second cookbook (following 'My Father's Daughter,' published in 2011), she lays out her plan to get her family healthy, which also includes letting her children eat as few carbohydrates as possible.

"Sometimes when my family is not eating pasta, bread or processed grains like white rice, we’re left with that specific hunger that comes with avoiding carbs," she wrote, which resulted in a litany of websites claiming she's starving her children.

Hysteria aside, London-based nutritionist Yvonne Wake still isn't on board and thinks Paltrow is being "foolish."

"Kids need carbohydrate because it gives them glycogen which keeps your brain going," she told the Daily Mail. "It’s like when kids don’t have any breakfast - they will do less well at school and won’t be able to run around with the other children."

Another nutritionist, Dr Carina Norris, said, "Cutting out such an important food group shouldn't be done without the advice of a medical professional, as it could put [the kids] at risk of nutrient deficiencies."

But honestly, if you name your kid "Apple" and let her eat grains, isn't some type of weird food-human interbreeding going on?

Meanwhile, the New York Post's Hailey Eber penned a blistering review of the book, saying it "reads like the manifesto to some sort of creepy healthy-girl sorority with members who use beet juice rather than permanent marker to circle the 'problem areas' on each other’s bodies."

Then the Atlantic Wire called it "the bible of laughable Hollywood neuroticism." Ouch.

If nothing else, at least you can use the book as a cutting board for your kale and gluten-free witch bread.
