Organ Meats—The Omnivore’s Multivitamin? | Liver, Iron Overload, and the Truth About Ancestral Diets | Ep. 404

  1. Organ Meats—The Omnivore’s Multivitamin? | Liver, Iron Overload, and the Truth About Ancestral Diets | Ep. 404 Jeff Armstrong 1:12:47

Are organ meats truly nature’s multivitamin—or just another nutrition trend making a comeback?

In this episode of Dr. Jeff Armstrong and Corbin Bruton explore the science behind organ meats, ancestral eating patterns, and the ongoing debate between plant-based and animal-based diets. From the nutrient density of liver to the risks of iron overload, they unpack what the research says about how humans should eat for long-term Health.

You’ll learn how organ meats compare to modern dietary patterns like the Mediterranean and Standard American Diet, why balance between minerals like iron, copper, and magnesium matters, and whether extreme diets—like carnivore or strictly plant-based—miss the mark.

If you’ve ever wondered whether you should be eating liver… or avoiding it altogether—this episode will give you a grounded, science-based perspective.
