...Food addiction reflects a broad range of issues, namely the brain and behavior, hedonic overeating, fat, sugar and desserts, and fMRI and PET research demonstrating strong similarities in ways drugs and certain foods affect/change the brain. Food, sex, gambling, and internet gaming cause changes that are quite similar, if not identical, to those produced by classical drugs of abuse in the reward systems of the brain. There are also phenomenological and psychological similarities between food cravings and cravings for drugs. Moreover, neuroscience in developing anti-obesity CNS agents that did not target eating, but rather shifted food preference (so broccoli might become as reinforcing as French fries) has failed. Obesity is one of the world’s chief public health problems and the intake of modern, processed foods may contribute to the addictive processes.
