The Forgotten Lemon

"The Forgotten Lemon – How science cured a disease and then forgot the cure" explores a deadly regression in medical knowledge. By the late 18th century, thanks to James Lind, the British Navy knew that citrus juice prevented scurvy. But by 1911, when Robert Falcon Scott raced to the South Pole, that knowledge had been lost. Science historian James C. Salt explains the tragedy. The rise of the "Ptomaine Theory" (that disease comes from bad meat) convinced experts that fresh meat, not vitamins, was the key. Scott's expedition packed sterile, lime-free food and died of scurvy-induced weakness. Amundsen, who ate fresh meat (containing Vitamin C) and berries, survived. "The Forgotten Lemon" is a chilling lesson on how scientific progress is not a straight line. It shows how bad theories can displace good ones, leading to the unnecessary deaths of heroes who marched into the ice with the wrong supplies.
