17. Zachary Taylor Died From Eating Too Many Berries
The 12th President Of The United States barely managed a year in office before popping his clogs. He worked his way up through the ranks of the military, his victories in the Mexican-American War won him election to the White House despite his vague political beliefs. He was a national hero regardless. He very much did not die a hero's death. In fact doctors at the time were sort of at a loss as to why Taylor suddenly died, and still there are theories that in the pre-Civil War United States he was poisoned by pro-slavery Southerners, but it was more likely he'd had some lethal reaction to swigging a pitcher of milk and eating a huge bowl of berries at a Fourth of July picnic.
