Links Relate Drug Abuse and Obesity
A Study find common brain changes and links between drug abuse and obesity:
"Animal studies suggest the same chemicals and brain circuits may be key to both, and that long-term brain changes make kicking the habit hard
New animal research helps explain why some eat without hunger or to excess. The studies explore the biological effects of poor eating habits, showing that high-fat diets cause lasting brain changes that may impair healthy eating. Additional studies show that food and drugs of abuse engage many of the same brain systems. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.
More than one billion adults worldwide are overweight, according to the World Health Organization. With increased risk for chronic disease and rising health care costs tied to obesity, today's studies are valuable in helping generate future prevention and treatment techniques.
Specifically, today's new findings show that:
* Animals fed a high-fat diet show long-term brain changes in the pleasure centers of the brain, illustrating the biological challenges for obese individuals (Teresa Reyes, PhD, abstract 299.18, see summary attached)."
