Bone marrow broth has become so popular that there’s even a takeout window in New York City where you pay upwards of $4 for an 8-ounce cup of broth on the go. Yes, seriously. Celebrity chef and cookbook author Marco Canora opened Brodo after drinking the broth to slim down, get healthy and “to combat the health effects of 20 years of caffeine, nicotine and alcohol,” he explained to Today.com. And he’s not the only one taking notice of this new delicious and incredibly healthy food trend. Other chefs, health experts and food bloggers are also on board the broth train, bringing attention to a nutritious food tradition that has actually been around for centuries.
