As all Mad Men fans now know, the main character, Don Draper, “found” himself at a wellness retreat — and presumably “taught the world to sing” by creating that iconic “Hilltop” Coca-Cola ad from 1971, which established Coca-Cola as a global brand: https://www.youtube.com/watch?v=2msbfN81Gm0 .

A few things happened when we bought the world a Coke.

In 2005, the Liquid Candy report was released, which tracked soaring obesity rates directly to the marketing of soft drinks: http://www.cspinet.org/sodapop/liquid_candy.htm

In 2010, a paper in Diabetes published a direct link to type 2 diabetes: people who consume sugary drinks regularly—1 to 2 cans a day or more—have a 26% greater risk of developing type 2 diabetes than people who rarely have such drinks: http://www.ncbi.nlm.nih.gov/pubmed/20693348

What are the ethics of allowing soft drink companies to continue to promote their products to children, or at sporting events? Should we impose similar advertising bans as we did with Big Tobacco? When the Mayor of New York City tried to impose a ban on Big Soda (as in jumbo size containers), it didn’t go very well:

In 2011, Coca-Cola began its own wellness campaign to offset public opinion:

Unlike Big Tobacco, which is an addictive carcinogen with a direct causal link to lung cancer (as we see in the fate of the character, Betty), Big Soda is not in the same category. It is only one of many factors in the type 2 diabetes delivery system.
