Protein intake increases IGF-1 levels and contributes to aging | Valter Longo

Parent Episode: Dr. Valter Longo on Resetting Autoimmunity and Rejuvenating Systems with Prolonged Fasting & the FMD

Similar in molecular structure to insulin, IGF-1 (insulin-like growth factor 1) has been implicated in the aging process. Protein intake increases IGF-1 levels in humans, independent of total caloric consumption. IGF-1 participates in a complex pathway known as the growth hormone/IGF-1 axis, where it exerts its role to accelerate aging. In this clip, Dr. Valter Longo explains how certain macronutrients influence the insulin/IGF-1/growth hormone axis to modulate aging in many cell types.
