The Importance of Collagen and Its Sources
Collagen, the most abundant protein in the body, plays a critical role not only in maintaining youthful skin but also in various other essential bodily functions. A significant amount of collagen consumed comes from animal products, often without consumers realizing it, as it can be hidden in supplements and food items. The podcast highlights how the meat and food industries heavily rely on collagen, derived from animal carcasses, to create various ingredients, including gelatin, which is crucial for products like gummy snacks and Jell-O. This reliance raises ethical questions about sourcing collagen, prompting the need for more sustainable alternatives.
