Gwyneth Paltrow and Jessica Alba Have Something to Tell You

(Reuters/Reuters)

Jessica Alba and Gwyneth Paltrow are two of our most prominent celebrity-turned-lifestyle experts, and it just so happens that they're both currently promoting their newest books.

Paltrow's newest book, "It's All Good: Delicious, Easy Recipes That Will Make You Look Good and Feel Great," is the follow-up to her well-received 2011 cookbook "My Father's Daughter," but this one comes with a twist: it's filled with gluten-free, sugar-free, meat-free and dairy-free recipes. Apparently, Paltrow had a traumatic health-related experience which lead her to seek out a new diet, and claims that she (along with her husband and two children) are reaping the health benefits of these alternative family recipes.

Her book, however, is already receiving some harsh critiques for being too extreme.

Alba seems to be following in Gwyneth's footsteps as somewhat of a mommy-mogul with her new offering, "The Honest Life: Living Naturally and True to You." After launching her own lifestyle and parenting website The Honest Company (similar to what Paltrow did with Goop), Alba has piled her best parenting tips, organic recipes, beauty secrets and natural cleaning techniques into her new tome. According to the book's website, Alba hopes to help readers "make healthy, affordable, non-toxic choices for your family — and have fun doing it."

Sounds great, but some outlets have labeled Alba's book as being too unrealistic for everyday moms.

So we're putting it to you: Whose advice would you most trust?
