Rockefeller Couldn’t Patent It. So He Buried It. The 100-Year Cover-Up of Silver in Medicine.

During the Black Plague of 1348, over 300 million people died worldwide. But less than a quarter of 1% of wealthy people were among them. The reason had nothing to do with luck — and everything to do with what they were eating with.
The phrase “born with a silver spoon in your mouth” was never about wealth. It came from the plague era, when doctors actually prescribed people to walk around with silver spoons because of what silver did to bacteria. Wealthy families gave silver pacifiers to newborns. The wealthy who ate off silverware daily were protected — and their skin even turned a faint bluish gray from the silver in their system. That is where the term “blue bloods” actually comes from.
