Marco Canora was a mess. “My body was in a sad state of affairs,” the chef and owner of New York’s Hearth restaurant recalls. Then he started sipping bone broth. Not only was he satiated, he was more calm. In response, he opened Brodo, a takeout window where he serves up to 400 cups daily. The collagen, amino acids, and minerals in the bones have been said to help repair tissue, reduce inflammation, and aid in the healing of joint injuries. Just ask Kobe Bryant, who swears the broth got him back in the game after a series of injuries. Whether these health claims would pass muster with the FDA, four out of five grandmothers would undoubtedly approve.
