Tag: Tanning process

Historically, people in times of extreme famine have resorted to eating boiled or roasted leather for survival, despite the known health risks. However, attempting to get nutrition from leather is a dangerous and ultimately futile endeavor due to modern processing methods and chemical toxicity.

While leather is predominantly made of collagen protein, the tanning process involving toxic chemicals makes it completely inedible and harmful for human consumption. Historically, people in desperate situations consumed leather, but it was not nutritionally viable and caused serious health problems. The key to understanding this lies in the stark difference between raw, digestible collagen and chemically treated, stabilized leather.

Approximately 99% of leather produced worldwide is a byproduct of the global meat and dairy industries. The question of where does cow skin come from is answered by examining the cattle farming sector, which is the primary source of the raw hides used for leather goods.
