The carbonated drink, 7-Up, is a favorite of many people. Probably, its refreshing lime flavor and being lightly carbonated are its features that makes it more preferrable than other soft drinks. Just recently, an essay published in The New York Times, mentioned that our favorite drink used to have lithium, a substance used to treat bipolar and depression.
Anna Fels, a psychiatrist and Cornell University professor, wrote the said essay. Fels also argued in her essay that drinking water should have low doses of lithium to decrease the rate of suicide, and other crimes caused by specific mental disorders.
According to Fels, water naturally has low amounts of lithium in it. Depending on the geographical location, the amounts of lithium in the water vary. Her point is, Mother Nature is already providing the humans what we should be drinking.
Fels added, "They [lithium] appear to decrease suicide rates significantly and may even promote brain health and improve mood."
In relation to, 7-Up's original formulation has lithium citrate. In fact, the reason behind 7-Up's brand name is its ingredients. Though, there are varying theories regarding 7-Up's name, one speculation says, the "7" in 7-Up is directed to its seven ingredients, including of which is lithium citrate. While, "Up" means, the effect of lithium in the human mind.
However, in 1948, the USFDA prohibited the use of lithium in certain goods, and other regulated products. Two years after, 7-Up removed lithium citrate in its ingredients.
All these issues about lithium, yet one thing's on my mind: where did Fido Dido go?
