“Endocannabinoids both act in the brain to increase appetite and also modulate taste receptors on the tongue to increase the response to sweets,” said study senior author Yuzo Ninomiya, Ph.D., Professor of Oral Neuroscience in the Graduate School of Dental Sciences at Kyushu University in Japan.

Endocannabinoids are substances similar to THC, the active ingredient in marijuana. Produced in the brain and body, they bind with cannabinoid receptors to help regulate appetite and many other processes involved in health and disease.
