Chris McCandless was the hiker and simple living advocate who died from starvation in Denali National Park in 1992. His story was later made into a book and movie called Into the Wild.

At The New Yorker, writer Jon Krakauer explains how the mystery of McCandless' death was finally solved. The evidence points to a secret of food chemistry with ties to Nazi death camps.
