The culprit is natural marijuana-like chemicals in the body called endocannabinoids, researchers from University of California, Irvine found.
They discovered that when rats tasted something fatty, cells in their upper gut started producing endocannabinoids. Sugars and proteins, the researchers noted, did not have this effect.
The process starts on the tongue, where fats in food generate a signal that travels first to the brain and then through a nerve bundle called the vagus to the intestines.
