As background, consider this NY Times article, which includes this:
A team of researchers at the University of North Carolina conducted a detailed survey of the packaged foods and drinks that are purchased in American grocery stores and found that 60 percent of them include some form of added sugar. When they looked at every individual processed food in the store, 68 percent had added sugar.Naturally the food processors liked the status quo. But with Michelle Obama as the spokesperson, they were defeated. Among the factors: Obama's image and clout, the easy contrast between self-interested food processors and those who want to improve the nation's health, and the absence of any broad-based coalition in favor of sugar. There's no NRA, no grass-roots organization, to provide support to the processors.
