A Nathan's Famous Hot Dog, with the bun, has 710 milligrams of sodium. According to Goldberg, someone with heart problems should shoot for fewer than 1,500 milligrams daily, or 2,000 milligrams if you're healthier. When Chestnut trounced Kobayashi, he ate roughly 46,860 milligrams of sodium in his winning meal.

That was from his 66 hotdog championship over Kobayashi in 2007. Yesterday's new world record, Joey "Jaws" Chestnut hit 70 hotdogs in 10 minutes. Salt lick anyone?
