QUESTION #1: BENEFITS OF BONE BROTH

Is bone broth all that people say it is? I hear that it can help with leaky gut and digestion - and it can be good for skin and overall health. Hard to know what is true and what is make believe these days! Thx for any thoughts.

Dear Carla,

I hear you! There is so much information out there, and it’s hard to know who to trust. So, bone broth is often touted for its potential benefits for gut health, skin, and as a source of protein, however the evidence behind these claims is mixed.

Bone broth contains an amino acid called glutamine, which may help reduce gut inflammation and improve the integrity of the gut lining. Animal and small-scale human studies suggest that glutamine supplements might be beneficial, but research on bone broth itself is limited. One small study on mice showed some promise, but human studies are needed to confirm these effects.

You may have also heard about collagen—it is essential for skin elasticity and firmness and it’s a key protein in bone broth. Some studies on collagen supplements suggest they may improve skin health, but these studies have been largely funded by the supplement industry itself! Moreover, the protein content in bone broth can vary widely, and the evidence for direct benefits of bone broth on skin is not terribly convincing.

Bone broth is a pretty good source of protein, with most of it derived from collagen. For example, a typical serving might contain 9 grams of protein, more than other broths and stocks. The gelatin formed from collagen adds to its nutritional value, making it a light, easy-to-digest option, especially when appetite is low. However, the protein content varies between homemade and store-bought versions.

The upshot: Bone broth is a relatively harmless addition to the diet, but it’s far from a miracle cure for gut health, joint pain, or skin issues. I will keep my eye out for more robust data on it and will keep you posted! 😊
