Among the numerous spoofs of the campaign, one of the more outrageous recreates the picnic scene with a man in drag playing the syrup-loving mom, though this time she is also defending lead from China, female genital mutilation (“It’s safe in moderation”) and K.K.K. cross-burning. Two Los Angeles comedians created the video, which has been watched more than 150,000 times.

Ms. Erickson says she has heard of the spoofs but has not bothered to watch most of them. “We’re really focused on trying to correct the record since a lot of the information consumers have is incorrect,” she says. “High-fructose corn syrup is a case of mistaken identity.”

Although it hasn’t done much good yet, Ms. Erickson continues to point out that science does not support the demonization of the product. One of her favorite documents is a two-page list of quotations defending the syrup, which she has culled from various media sources. Many are attributed to people like Ms. Nestle, who spend much more time criticizing the food industry than defending it.

On the list there’s Michael Jacobson, executive director of the Center for Science in the Public Interest; David S. Ludwig, director of the Optimal Weight for Life Clinic at Children’s Hospital Boston; Walter Willett from the Harvard School of Public Health; and even Barry Popkin, a nutrition professor at the University of North Carolina and a co-author of that 2004 obesity paper.

Recent studies “have convinced me that H.F.C.S. does not affect weight gain,” he told The Los Angeles Times in July 2008.

And as for those mercury studies that spread like wildfire last year, Ms. Erickson says that there is no reason to believe that the mercury detected in various foods was coming from high-fructose corn syrup.

In a further attempt to improve its image, the Corn Refiners Association has petitioned the Food and Drug Administration to allow a name change to the simpler, less-chemical-y “corn syrup.” In January, the F.D.A. issued a letter to the Corn Refiners giving its thumbs-up to the name change. But after an objection from the Corn Refiners’ rival, the Sugar Association, F.D.A. officials sent another letter saying that they needed to give the matter further thought.
