Scientists have discovered a new pathway in the insect brain that may hold the key in triggering impulsive eating, a report said. Researchers from the University of Georgia said that neural pathways in insect’s brains that is supposed to be a trigger mechanism to engage in eating for pleasure. The new discovery could mirror how the human brain could also have pathways that could also trigger impulsive eating.

Scientists know that hungry insects tend to be more aggressive and are willing to exert effort to find food. Now scientists have discovered that there is a part in the insect’s brain that makes them excited about food when they smell something is great for them to eat even if they are not hungry.

Researchers were surprised that insects have this impulsive eating mechanism based on a reward cue. They found out appetizing odors which are emitted generally by sugar-rich foods cause impulsive eating behavior in insects. Insects are repelled by non-appealing meals. The findings suggest that eating for pleasure is not an invention of modern society and exists since antiquity and even displayed by lower life forms such as insects and are not exclusive to humans.
