A number of folks —- some of whom don’t even work for the Sugar Association —- are getting all excited about Pepsi’s eight-week trial run for two new soft drinks, Pepsi Throwback and Mountain Dew Throwback, that will be produced with all-natural sugar, rather than with high-fructose corn syrup.

Soft drink manufacturers turned to high-fructose corn syrup in the mid-1980s when sugar prices started to spike, but lately consumers have rebelled against the corn-based sweetener when lab studies on rats tied it to obesity and diabetes.

The Sugar Association is hoping soft drinkers will buy Throwback bottles by the caseload, putting pressure on Pepsi to make these brands permanent. But as this site points out, there’s still a lot of economic pressure for soda manufacturers to stick with the corn stuff.

At least until the government stops subsidizing corn.
