A South American proverb claims "Good broth will resurrect the dead." While that's clearly an exaggeration, chicken soup has enjoyed a reputation as "Jewish penicillin" and bone broths are served to convalescents all over the world. In this presentation,
Dr. Daniel in the youtube video below reviews the science that supports consuming bone broth for healthy bones, joints, skin, digestion, immunity and emotional stability.
She discusses the 19th and early 20th century studies on gelatin, as well as recent investigations into the "conditionally essential" amino acids proline, glycine and glutamine and "the essential sugars" N-Acetylglucosamine and N-Acetylgalactosamine.
Finally, she will report on Dr. John F. Prudden's clinical trials healing osteoarthritis, rheumatoid arthritis, Crohn's, and even cancer with cartilage.
In short, much science supports the ancestral wisdom of consuming bone broth.
