Since this blog was published in January, research done on rats by Dr. Francesco Leri, an associate professor of neuroscience and applied cognitive science at the University of Guelph in Ontario, Canada (which we talked about two weeks ago) has determined that high fructose corn syrup is indeed an addictive substance. Dr. Leri found that that the more he increased the percentage of HFCS, the more the rats worked to obtain it, which is “exactly what you notice with drug abuse, the same type of pattern.” Nor did satiating the rats on their regular chow make the craving for HFCS go away. When administered saccharine, however, the rats did not continue to crave it as they had with HFCS. To Leri, this indicated that ”HFCS has effects that are beyond the sweetness in the mouth … effects on the brain.”
Industrial Sweetener Implicated as Cause
of Global Obesity Epidemic
WASHINGTON, DC – New research by a neuroscientist has found that lab animals self-dosing on High Fructose Corn Syrup (HFCS), the industrial sweetener used in hundreds of grocery store products, followed the same pattern of behavior as those that were self-dosing on cocaine.
Addiction expert, Dr. Francesco Leri, an Associate Professor of Neuroscience and Applied Cognitive Science at the University of Guelph in Ontario, Canada, presented new research to the Canadian Association for Neuroscience that showed how High Fructose Corn Syrup caused behavioral reactions in rats similar to those produced by addictive drugs. He concluded that, “Addiction to unhealthy foods could help explain the global obesity epidemic.”
In Dr. Leri’s tests, the lab animals could press a lever and receive as many doses of HFCS as they wanted. He discovered that the more he increased the sweetness concentration of the HFCS, the more the subjects worked to obtain it.
