My absolute favorite Bone Broth recipe is from Nom Nom Paleo, check it out here. I just made my third batch yesterday. I have been using the broth for the soups I've been making during my Standard Process 21 Day Detox. Day 5 and I am starting to feel better! Here's a bit of great information from the folks at Paleo Leap!
Benefits of Bone Broth: Detox
Glycine also helps in detoxification – the actually meaningful kind, not the ridiculous nonsense about unspecified “toxins” and the necessity of removing them by embarking on long fasts or juice cleanses. None of those special cleanses are necessary, because your body has its own detox system: your liver. Glycine gives the liver a hand up in removing anything dangerous from the body – for example, in one rat study, rats fed glycine showed significant improvements in recovery from alcohol-induced fatty liver disease compared to rats that weren’t.
Glycine is also necessary for the synthesis of glutathione and uric acid, the body’s most important endogenous antioxidants. As described in the article on antioxidants, boosting production of the endogenous (internally produced) antioxidants is much more useful for reducing oxidative stress than taking Vitamin C or other antioxidant supplements.
Yet another detox-related benefit is that glycine helps clear out excess methionine, another amino acid found in large quantities in eggs and muscle meat. Methionine is an essential amino acid, but too much of it can raise blood levels of another amino acid called homocysteine, and the process of breaking down homocysteine increases the body’s need for B vitamins (thus increasing the risk of B vitamin deficiency even if your intake is adequate). Glycine from broths and cartilage can help break down homocysteine without the need for B vitamins. This is a perfect example of the wisdom of traditional cultures in eating every part of the animal: the proteins in the muscle meat and the proteins in the connective tissue balance each other out for optimal nutrition.
