Study: Fructose blamed for rise in obesity

Researchers say they’ve found more evidence of a link between a rapid rise in obesity and a corn product used to sweeten soft drinks and food since the 1970s.

The researchers examined consumption records from the U.S. Department of Agriculture for 1967-2000 and combined it with previous research and their own analyses.

The data showed an increase in the use of high-fructose corn sweeteners in the late 1970s and 1980s “coincidental with the epidemic of obesity,” said one of the researchers, Dr. George A. Bray, a longtime obesity scientist with Louisiana State University System’s Pennington Biomedical Research Center. He noted the research didn’t prove a definitive link.

“Body weights rose slowly for most of the 20th century until the late 1980s,” Bray said. “At that time, many countries showed a sudden increase in the rate at which obesity has been galloping forward.”

The study is being published in the April issue of the American Journal of Clinical Nutrition.
