Washington: Research shows that high-fructose corn syrup can cause behavioural reactions in rats similar to those produced by drugs of abuse such as cocaine. These results, presented by addiction expert Francesco Leri, Associate Professor of Neuroscience and Applied Cognitive Science at the University of Guelph, suggest food addiction could explain, at least partly, the current global obesity epidemic. The " Food Addiction" hypothesis suggests one could be addicted to food just as one is addicted to drugs of abuse. To test this hypothesis, Dr. Leri studied the response of rats to foods containing unnaturally high concentrations of sugar, fats and taste enhancers, such as high-fructose corn syrup and foods like oreo cookies.Increased availability of such highly-palatable foods could partly explain the high incidence of obesity around the world, but simple availability does not explain why some people are obese and others are not, given the same amount of available food.
