Bone broth is being promoted as a health elixir to reduce joint pain and beautify skin and hair. Let’s science it. Although its trendy right now, bone broth is nothing new. It is made by slowly simmering animal bones in water to extract nutrients. The health claims are built on bone broth as a source of the protein collagen. Collagen is a long twisty protein that forms the structure of bones, cartilage and skin. If you’ve ever made stock at home that has a wobble to it, this is from collagen that is broken down into smaller fragments called gelatin. Same stuff that makes jello jiggle. Now for the health claims. Joint pain due to general wear and tear or osteoarthritis is caused by decreased collagen in the cartilage that pads our joints. Collagen also forms the architecture of skin. As we age, skin collagen breaks down, contributing to wrinkles. Bone broth is a source of collagen, so does drinking bone broth provide collagen to our skin and joints? There haven’t been any studies looking at bone broth for these applications - but even hypothetically, it isn’t feasible that collagen from bone broth could get to these tissues. Nothing in nutrition makes sense unless we consider the processing and digestion of nutrients. When making bone broth you have to heat the bones in water. Heating proteins breaks them down, so the process of making bone broth breaks down the collagen into smaller pieces - remember that wobbly gelatin! When you drink the bone broth, digestive enzymes further break down the protein into individual amino acid building blocks. This is a good thing because we can’t absorb big proteins into our blood, but we can absorb those amino acids. Doesn’t matter if it is collagen or any other protein from meat or plants, they all get broken down into amino acid building blocks before entering our bloodstream. From there, the amino acids will get sent wherever the body needs them - you can’t will them towards to joints or skin to build collagen. So bone broth is not a magic bullet to alleviate joint pain or smooth skin - but that doesn’t mean that you shouldn’t eat it. I just wouldn’t go out of my way to pay a bunch of extra money or spend a bunch of extra time making it in an effort to enhance joint or skin health. Our body naturally produces collagen as long as you have sufficient vitamin C - so don’t be vitamin C deficient, then you definitely can’t make collagen! Sadly, we haven’t figured out ways to stimulate our body to produce more collagen in joints or skin later in life, so the best we can do is try to maintain the collagen we have by not smoking and reducing sun exposure. I fully support making bone broth at home as a way to use the whole animal and serve as a base for healthy soups. Here in the Nourishable household we make delicious stock from leftover chicken and turkey carcasses, and we use to when making soups full of veggies and barley.
