We have been interested in the intersection between nutrition and substance use disorder for many years. David Wiss has published several peer-reviewed articles and book chapters on this topic. There has been some progress in the field, but we are still lacking prospective research which shows that nutrition can improve addiction-related outcomes. This is a difficult task because these trials require long-term follow-up which is not always easy with this population. We are hoping to see more evidence in this arena of a substance use disorder, and are happy to help out if anyone is interested in conducting research. We hypothesize that nutrition interventions can improve depressive symptoms via the gut-brain axis.

It is important for every person who is recovering from a substance use disorder to adopt good eating habits. This will further help prevent nutrition disorder by eliminating toxic substances and defending your body against the damage.

Recently Dr. David Wiss recorded a 19-minute recap of his work in this area. Check it out and please let us know if you have any thoughts about the intersection between nutrition and substance use disorder.

The main paper discussed in the video “Staff-Perceived Barriers to Nutrition Intervention in Substance Use Disorder Treatment” has been published in the prestigious Public Health Nutrition journal and be accessed HERE.
