How PUFA Fats Affect Thyroid Function and Energy

In this first episode, real food nutritionist, healer, and regenerative farmer Heathar Shepard explores the hidden health impacts of polyunsaturated fatty acids (PUFAs). She explains how excess PUFA consumption can suppress thyroid function, disrupt hormone balance, and slow metabolic health. Heathar also uncovers surprising dietary sources of PUFAs—far beyond seed oils—that often hide behind misleading marketing. Learn why humans require only small amounts of these fats, how stored PUFAs affect cellular function, and practical ways to support a higher basal metabolic rate (BMR) by lowering PUFA intake and supporting the body’s natural detox processes.In this episode:What polyunsaturated fatty acids (PUFAs) do inside the bodyWhy excess PUFAs may suppress thyroid functionHidden dietary sources beyond seed oilsHow stored PUFAs affect metabolismSupporting metabolic rate by lowering PUFA intake
