What Is Bone Broth—And Why Are People Suddenly Into It?

There’s a hot new drink in town and it has nothing to do with Mezcal or smoked Himalayan sea salt. If you know anyone who fancies herself a paleo, primal, and/or ancestral eater, perhaps you’ve heard that person mention rave about the magical elixir that is bone broth. Devotees claim this brew — made by boiling bones for the amount of time it would take to drive from Yonkers to Vegas — helps with everything from joint pain to serious medical conditions, including autoimmune disorders and even cancer. But, is bone broth really the panacea it’s made out to be? Let’s dig in.

What is bone broth, anyway?
“Bone broth is made by boiling animal bones — poultry, beef, and fish are all good options — for a minimum of four hours, although some people will go as long as 48,” says Ariane Resnick, personal chef and certified nutritionist. This can be done either in a pot or a slow cooker, if you can’t man the stove for hours on end. The goal is to boil the bones long enough so that they begin to disintegrate and release their structural components — primarily calcium phosphate and collagen. Bone broth is not the same thing as regular broth, which is typically made by boiling meat, some bones, and vegetables and spices for roughly an hour or two, says Resnick. Although there is nutritional value in regular broth, there’s not enough bone or time involved to extract the same amount of concentrated nutrients that come in a bone broth.

Who dreamed up this concept? 
“There is evidence of bones being broken into bits by fire pits throughout the world in prehistoric times,” says Cate Shanahan, MD, author of Food Rules: A Doctor’s Guide to Healthy Eating and Nutrition Director for the Los Angeles Lakers. Yes, it appears that everything old is new again.

Why is it so good for you?
According to the experts, good bone broth is like drinking liquid bone. Why on earth would you want to do that? Many, including Resnick and Dr. Shanahan, say drinking bone broth delivers a range of benefits, from stronger bones and joints to shinier hair and even improved immune function.

Bone broth for joint pain
If you’re over the age of 25 and played any kind of sport growing up, glucosamine — the supplement that’s supposed to help with joint pain — might be on your radar. But, this is just one of the glycosaminoglycans (GAGs) in bone broth. You also get chondroitin, hyaluronic acid, and multiple other GAGs that have been shown to stimulate cells to create new collagen in your joints, tendons, and ligaments, potentially providing some relief for those aching knees.

Bone broth for allergies and autoimmune conditions
Both food allergies and autoimmune conditions have been linked to intestinal permeability, or when microscopic holes in the lining of your gastrointestinal tract allow undigested food particles to pass directly into your bloodstream. But, the gut is constructed almost entirely of cartilage and collagens, says Dr. Shanahan, so the cells that are stimulated by the components in bone broth can also help restore the intestinal barrier. For this reason, bone broth has become a cornerstone of what is known as the Autoimmune Protocol (AIP) diet — a real-food diet that has been anecdotally shown to help treat a wide range of autoimmune conditions.

Bone broth for inflammation
According to Resnick, bone broth made from grass-fed beef bones also contains omega-3 fatty acids and conjugated linoleic acid (CLA), which have been linked to reducing inflammation in the body and could be helpful for people suffering with an inflammatory condition.

Where’s the proof?
In the past 50 years, almost no clinical research has been done on bone broth, but for Resnick and Dr. Shanahan, personal experience is certainly promising. Dr. Shanahan credits bone broth, along with other elements of her nutrition program, with helping the Lakers deal with chronic joint problems. 

How much do I need to drink? 
Unfortunately, this isn’t a one-and-done kind of thing. Dr. Shanahan recommends working up to one cup three to four days per week, minimum, before you start seeing results. She also notes that it won’t work as effectively in the context of a high-sugar or pro-inflammatory diet; she specifically calls out highly processed ingredients such as vegetable oils, which are in almost all commercially prepared foods and are known to be inflammatory.

What about bone marrow?
Bone marrow is a rich source of monounsaturated fats and, like bone broth, alsocontains anti-inflammatory omega-3 fatty acids and CLA. But, according to Dr. Shanahan, the collagen and glycosaminoglycan molecules we’re after in bone broth come primarily from cartilage and joint tissue. Resnick recommends buying a combination of marrow bones (look for bones with a solid, white center) and regular bones.
