Why Scurvy Doesn't Make Sense to Science

The video discusses scurvy, a disease caused by vitamin C deficiency, highlighting its symptoms and treatment. It explains the role of vitamin C in collagen synthesis and how most animals can produce it naturally, unlike humans. The loss of this ability in primates is attributed to a genetic mutation affecting the GULO enzyme. The video explores why this mutation persisted, suggesting a lack of selective pressure due to vitamin C-rich diets in tropical environments. It concludes by emphasizing the importance of ensuring adequate vitamin C intake to prevent scurvy.
