Slaughtering Sacred Cows: The Vitamin A Debate, Toxic Bile, and Copper Concerns with Dr. Garrett Smith

Organ meats. Retinol. Detox protocols. Sacred cows in the alternative health world.Dr. Garrett Smith, aka the Nutrition Detective, joins us to unpack the growing debate around vitamin A toxicity, bile metabolism, and why some of the most celebrated “superfoods” may not work the same for everyone.At the center of the conversation is his Toxic Bile Theory — the idea that bile is not just a digestive fluid, but one of the body’s primary waste routes. When overloaded, he argues, it can shift from protective to inflammatory and drive chronic symptoms many people can’t seem to resolve.We explore where detox culture goes wrong, why “healing crises” may not be what they seem, and why stopping ongoing exposures may matter more than adding another supplement.In this episode, we discuss:The Vitamin A debate: deficiency vs. toxicityWhy serum retinol levels often rise with ageToxic Bile Theory and bile as a terrain issueOrgan meats and why some people feel worse on themDetoxification vs. agitationRaw milk vs. conventional milk — what actually mattersCopper toxicity concerns and mineral balanceWhy MSG may be good for you (seriously!)This episode will challenge assumptions, especially for those in ancestral or nose-to-tail nutrition circles. As always, the goal isn’t to dictate conclusions, but to examine ideas and test them against your own experience and terrain.You can learn more about Dr. Smith at his website https://nutritiondetective.com/ and also follow him on Youtube at https://www.youtube.com/nutritiondetective, and on X at https://x.com/NutriDetect.Support Terrain Theory on Patreon!
