Summary
Yale-educated biochemist Dr. Joel Brind joins Morning Air to explain his theory that chronic inflammation is driven by widespread glycine deficiency rather than being a normal response to injury. Brind, who founded Natural Food Science and authored The Glycine Miracle, argues that the body's inflammatory first responders overreact when glycine levels are too low. He traces the modern glycine shortfall to dietary changes: we no longer eat bone broth, skin, and connective tissue the way previous generations did, while consuming more muscle meat that is high in methionine and low in glycine. Host John Morales shares his own experience using glycine supplementation to manage severe shingles pain, describing rapid relief within 30 minutes of dosing.
Key Points
- Chronic inflammation may be driven by glycine deficiency rather than being an inevitable response to injury
- Glycine is the most abundant amino acid in the body but is considered "non-essential," discouraging research funding
- Modern diets lack glycine because we discard bones, skin, and connective tissue that grandparents cooked with
- Excess methionine from muscle meat further depletes glycine, which the liver uses to clear excess amino acids
- Host reports glycine reduced shingles nerve pain from 9 to 6 within 30 minutes
- Dr. Brind links glycine deficiency to heart disease, cancer, arthritis, diabetes, and Alzheimer's disease
- Bone broth and collagen supplements provide glycine but concentrated supplements deliver more per serving
Key Moments
Inflammation is a glycine deficiency problem
Dr. Joel Brind argues that inflammation in response to injury is not natural but a sign of glycine deficiency. He compares immune first responders to police who start shooting at an accident scene when glycine is missing.
"What I've discovered is that the reason everybody experiences that inflammation in response to injury, just as I always did, was a deficiency in this simple amino acid called glycine."
Modern diets create glycine deficiency
Dr. Brind explains that previous generations ate bone broth and connective tissue rich in glycine, but modern diets discard those parts. Meanwhile, excess methionine from muscle meat further depletes glycine stores.
"Grandma used to throw it in the soup. Now we all throw it in the trash, right? If we even ever see it by the time we get that muscle meat. Well, the muscle meat has a lot of good, what they call essential amino acids, but it's very, very low in glycine. Glycine is all in the bones."
Glycine rapidly reduces shingles pain
Host John Morales shares his personal experience using glycine supplementation to manage severe shingles nerve pain, reporting that it outperformed both over-the-counter and prescription pain medications.
"First thing in the morning, I would just take one packet of sweetamine, and within half an hour, I could feel the difference. You know, the pain would go from a 9 to about a 6."
Chronic disease linked to glycine-driven inflammation
Dr. Brind connects glycine deficiency to chronic inflammation underlying heart disease, cancer, arthritis, diabetes, and Alzheimer's, arguing that immune cells attack normal tissue when glycine levels are insufficient.
"Most chronic diseases, most of the things that make people sick and die these days, including heart disease, cancer, arthritis, diabetes, Alzheimer's disease, many of those things, even autism at the beginning of life, all of these things are characterized by chronic inflammation."
