From the Ted Talk by Carolyn Freiwald: The hidden history found in your teeth

Unscramble the Blue Letters


But we're not interested as much in your family's migration history as yours. And that's where we go to the ttooh enamel, what it's made out of, to try and find out if a person mevod and even when they moved. And it's based on one simple idea: that you are what you eat. All the minerals and the etneemls in the food, like cualcim, oxygen, which is the O in H2O, sodium and salt, can tell us something about your diet. So we know if you like cornbread or white bread, if you prefer pork, chicken or if you really like seafood. There are other elements that tell us where that food came from, and that includes sulfur, strontium, oxygen and even lead, which, of course, you don't want very much of. But these tell us where the food comes from and that can tell us where you were when you were eanitg it. And that is what agslrioheaotcs use to identify ancient migration.

But we're not interested as much in your family's migration history as yours. And that's where we go to the tooth enamel, what it's made out of, to try and find out if a person moved and even when they moved. And it's based on one simple idea: that you are what you eat. All the minerals and the elements in the food, like calcium, oxygen, which is the O in H2O, sodium and salt, can tell us something about your diet. So we know if you like cornbread or white bread, if you prefer pork, chicken or if you really like seafood. There are other elements that tell us where that food came from, and that includes sulfur, strontium, oxygen and even lead, which, of course, you don't want very much of. But these tell us where the food comes from and that can tell us where you were when you were eating it. And that is what archaeologists use to identify ancient migration.
