There is excellent emerging data on the contribution of ultra-processed foods to mental health outcomes (and other medical conditions). Ultra-processed food tends to contain a high number of food additives. One class of food additives in particular, flavor enhancing food additives, tend to create an unnatural attraction to these processed foods, while also having the ability to affect nervous system functioning in certain individuals. The main component of these additives is glutamate, an amino acid which has the ability to stimulate neurons in the tongue (making food taste better) while also having the ability to affect nervous system function elsewhere. This presentation will teach clinicians about this dietary exposure and how it has been tied to mental health disorders. Currently, clinicians do not receive training in nutrition, and thus, are unable to offer advice in this area. This talk will educate attendees about the role of glutamatergic neurotransmission in mental health and will also provide easy-to-use tools for helping people change their eating behaviors.
