You don't eat the limestone — you drink it! Kind of! Beneath Kentucky's soil is tons and tons of calcium-rich limestone, which filters out much of the iron and makes for some of the most delicious water you'll ever drink. It's also a reason that the bourbon is so fantastic; this limestone-kissed water is used to make it.

It's also listed as a reason why Kentucky's racehorses are among the best in the world — the water filtered through the limestone makes for strong, healthy horse bones.
