“Good broth resurrects the dead.”

This Latin-American saying sounds way over-the-top, but if celebrities like actress and producer Salma Hayek swear by bone broth, there’s got to be some veracity to it… right?

Salma Hayek, creator of Nuance Skincare and physically deceptive 50-year-old, tells People.com, “It’s full of gelatin and fat and has bone marrow and I think it is very good to keep yourself young,” adding that it’s helped her to avoid Botox.

Superhuman former Los Angeles Laker Kobe Bryant, too, has been known to consume bone broth (by way of chicken tortilla soup) for quite a while. “It’s great—good for energy and reducing inflammation,” he told ESPN.com.

Shailene Woodley, Mindy Kaling, and Gwyneth Paltrow are also believers. (Uh huh, it’s goop-approved.)

So what’s the hype all about? Bone broth is made by simmering bones of beef, chicken, or fish for extended periods of time, often over 24 hours. This stewing process is thought to release compounds like collagen, the protein responsible for taut, uplifted skin. Nutrition researchers Sally Fallon and Kayla Daniel of the Weston A. Price Foundation explain that the soup also contain easily absorbable minerals, including calcium, magnesium, phosphorus, and sulphur.
