Zachary Taylor, the 12th President of the United States, met an unexpected demise shortly after consuming a meal that included raw fruit and iced milk. On July 4, 1850, during a celebration of Independence Day, he ate a variety of foods, including cherries and iced milk. Just five days later, he fell ill with severe stomach pains, and by July 9, he had succumbed to what was initially thought to be a stomach ailment. His death took place in the White House, where he had been serving a little over sixteen months in office. His condition worsened quickly, and despite the efforts of medical professionals at the time, he passed away, leaving the nation shocked.

Taylor's presidency was characterized by significant tensions over slavery in the territories, and his death led to Vice President Millard Fillmore assuming office. Fillmore's ascension marked a pivotal moment in U.S. political history as debates on issues such as the Compromise of 1850 became increasingly urgent. Taylor had been an opponent of the expansion of slavery, which contrasted sharply with the policies Fillmore later supported as a moderate Whig.

The sudden nature of his passing raised numerous questions related to his health, diet, and the impact of presidential health on governance. Understandably, it sparked discussions about the dietary habits of political leaders and how they may affect their duties and responsibilities. Speculation about Taylor's death also fed into conspiracy theories, especially given the political tensions of the era, although most historians generally agree it was more likely due to illness rather than foul play.
