Should We All Take a Bit of Lithium?

> 7-Up was originally called Bib-Label Lithiated Lemon-Lime Soda and contained lithium citrate right up until 1950. In fact, it’s been suggested that the 7 in 7-Up refers to the atomic mass of the lithium. (Maybe the “Up” referred to mood?) Even beer made with lithia water was available.

What. Wow, that's pretty fascinating. It seems like it would be a helpful project to create a sort of web timeline of these key ingredient changes in various products over the years. At least people could become more aware of the related conversations around those ingredients and perhaps make more informed dietary decisions as a result.
