My obsession with bone broth is no secret; I just plain love the stuff, and I think incorporating it into your diet is essential for optimal health. In fact, I’ve written multiple blog posts and had a podcast episode dedicated to bone broth! Bone broth is a flavorful liquid made by boiling the bones of just about any vertebrate you can think of (typically poultry, beef, bison, lamb, or fish) in water for an extended period of time (typically anywhere from 4 hours to 40 hours!). Often vegetables and herbs are added (typically carrots, onion, celery, garlic and I like to add bay leaves too). The bones from mammals need to be sawed open, whereas fowl and fish bones don’t. The used bones and vegetables are strained from the liquid and typically discarded. The resulting liquid is called “broth” or “stock” and is rich in numerous vitamins, minerals, and antioxidants (especially calcium, magnesium and phosphorous, which are essential for bone health). Most importantly, bone broth is also particularly rich in two very special amino acids: proline and glycine.
Glycine and proline are two key components of connective tissue, the biological “glue” that holds our bodies together. There are many types of connective tissue and these two amino acids feature prominently in most of them, from the cartilag
e that forms our joints to the extracellular matrix that acts as a scaffold for the cells in our individual organs, muscles, arteries etc. Without these two amino acids, we would literally fall apart. So, it is no surprise that we need these two amino acids to heal, not only gaping wounds, but also the microscopic damage done to blood vessels and other tissues in our body caused by inflammation and infection. In fact, glycine is known to inhibit the immune system and reduce activation of inflammatory cells in your body. Whether you are trying to heal from an infection, address an autoimmune disease, or reduce inflammation caused by neolithic foods or Small Intestinal Bacterial Overgrowth, high levels of dietary glycine are critical.
In addition, glycine is required for synthesis of DNA, RNA and many proteins in the body. As such, it plays extensive roles in digestive health, proper functioning of the nervous system and in wound healing. Glycine aids digestion by helping to regulate the synthesis and of bile salts and secretion of gastric acid. It is involved in detoxification and is required for production of glutathione, an important antioxidant. Glycine helps regulate blood sugar levels by controlling gluconeogenesis (the manufacture of glucose from proteins in the liver). Glycine also enhances muscle repair/growth by increasing levels of creatine and regulating Human Growth Hormone secretion from the pituitary gland. This wonderful amino acid is also critical for healthy functioning of the central nervous system. In the brain, it inhibits excitatory neurotransmitters, thus producing a calming effect. Glycine is also converted into the neurotransmitter serine, which promotes mental alertness, improves memory, boosts mood, and reduces stress.
Proline has an additional role in reversing atherosclerotic deposits. It enables the blood vessel walls to release cholesterol buildups into your bloodstream, decreasing the size of potential blockages in your heart and the surrounding blood vessels. Proline also helps your body break down proteins for use in creating new, healthy muscle cells. You make your own using my chicken bone broth recipe.
