Finally, a reason why most of us have such a hard time eating just a single potato chip! Turns out that fatty foods affect your brain in a similar way to marijuana as it activates brain chemicals called endocannabinoids that "produce a drug-like feeling," which ultimately encourages you to eat more to keep it continuing. The new study states:
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. There, the signal stimulates the production of endocannabinoids, which initiates a surge in cell signaling that prompts the wanton intake of fatty foods, Piomelli said, probably by initiating the release of digestive chemicals linked to hunger and satiety that compel us to eat more.
