Jordan Rubin Joins Dr. Josh Axe to Discuss Overlooked Healing Foods
Dr. Josh Axe and Jordan Rubin make the case for organ meats, glandulars, bone marrow and colostrum as the original peptide foods.
On the October 22, 2026 episode of The Dr. Josh Axe Show, Dr. Josh Axe and Jordan Rubin discussed more than 20 lesser-known healing foods, starting with peptide-rich organ meats and glandulars.
Dr. Josh Axe opened by noting that today's popular isolated peptides, such as BPC-157 and TB-500, have natural counterparts in food, and that organs and glandulars have long been eaten as peptide-rich foods. Rubin said bovine pancreas and thymus, both called sweetbreads, have been eaten for thousands of years, and Dr. Axe described thymus as a natural source of thymosin peptides. Both said organs can be eaten as food or taken as glandular supplements. Rubin called bone marrow a delicacy that some finer restaurants serve, said colostrum carries IGF-1, a growth factor, and suggested asking a local raw milk co-op for raw, frozen colostrum. He named deer antler as another growth-factor-rich food, and said kefir carries more peptides than yogurt because it is fermented with both bacteria and yeasts.
Peptides are short chains of amino acids that act as signals in the body. Traditional diets prized organ meats on the idea that like supports like, and Dr. Axe's point is that eating more organs is the simplest way to get these compounds from food instead of from an isolated product.

This is a conversation about traditional use and the hosts' experience, not a trial. The episode presents no controlled data on how much of these peptides survive digestion or what doses do in people.

These organs and glandulars, they're very easy to consume as the actual organ or actually as a supplement.
Dr. Axe’s Take
Organ meats and glandulars are some of the most nutrient-dense foods you can eat, and I think the peptide conversation explains why traditional cultures prized them. Liver, bone marrow and colostrum carry signaling compounds your body can use, which is a very different thing from a synthetic isolate. My practical step this week: work one serving of liver into your diet, sautéed with garlic and onions or blended into ground beef, and add bone broth a few times this week. And listen, never stop or change a medication on your own. Make that change with your practitioner.
