How Junk Food Works

In this fascinating episode of Stuff You Should Know, Josh and Chuck dive into the surprisingly complex world of junk food, exploring how it evolved from simple treats into a scientifically engineered industry. They trace the history from Civil War rations to iconic snacks like Cracker Jacks and reveal the mind-blowing origin stories behind beloved (and not-so-beloved) foods - including which famous cookie was actually the knockoff. The hosts also examine the sophisticated science behind junk food's addictive qualities, from the "bliss point" that keeps you reaching for more Cheetos to how companies use clever packaging and marketing to hook consumers from childhood.
