More than Meets the Eye: Linking Nutrition & Behavioral Health

Today is Saturday March 28, 2020. The world is in quarantine due to COVID-19 and many are in a behavioral health crisis. I am not depressed about it although certainly concerned for the welfare of my fellows, particularly those in recovery. I have been conducting Zoom and FaceTime sessions with people all over the world and doing what I can to be helpful. I do have more time to work on manuscripts and other academic projects. Tonight I will be coding up some variables for a data analysis.

Last night I had the idea to share my latest presentation with my newsletter followers. So I spent an hour recording my latest presentation “More than Meets the Eye: Linking Nutrition & Behavioral Health.” I hope you enjoy!

The presentation discusses: Traumaadversitynutritioneating disorders, substance use disorders, opioid crisis, food addiction, neurosciencegut-brain axismicrobiome, recovery, treatment and so much more! Nutrition for behavioral health is the future!

Biopsychosocial Opioid Video 6:42

 The opioid crisis has reached epidemic proportions in the United States with rising overdose death rates. Identifying the underlying factors that contribute to addiction vulnerability may lead to more effective prevention strategies. Supply side environmental factors are amajor contributing component. Psychosocial factors such as stress, trauma, and adverse childhood experiences have been linked to emotional pain leading to self-medication. Genetic and epigenetic factors associated with brain reward pathways and impulsivity are known predictors of addiction vulnerability. This review attempts to present a biopsychosocial approach that connects various social and biological theories related to the addiction crisis. The emerging role of nutrition therapy with an emphasis on gastrointestinal health in the treatment of opioid use disorder is presented. The biopsychosocial model integrates concepts from several disciplines, emphasizing multicausality rather than a reductionist approach. Potential solutions at multiple levels are presented, considering individual as well as population health. This single cohesive framework is based on the interdependency of the entire system, identifying risk and protective factors that may influence substance-seeking behavior. Nutrition should be included as one facet of a multidisciplinary approach toward improved recovery outcomes. Cross-disciplinary collaborative efforts, new ideas, and fiscal resources will be critical to address the epidemic.

A Biopsychosocial Overview of the Opioid Crisis: Considering Nutrition and Gastrointestinal Health

I spent an entire year working on this manuscript! It was quite an undertaking because employing an “overview perspective” of something as vast as the opioid crisis requires expertise in several different domains. Specifically, this paper covers environmental factors (i.e. exposure to pharmaceutical pain killers) as well as psychosocial factors (e.g. stress, trauma, childhood adversity) in conceptualizing susceptibility to opioid addiction. The most novel contribution relates to the role of nutrition in recovery from opioid use disorders. The model created can be used to conceptualize substances other than opioids, including food.

Food Addiction and Disordered Eating Webinar

Sorting Through Dialectical Truths

In this webinar, David Wiss MS RDN helps you sort through dialectical truths that plague the nutrition profession. People seem to pick a “campsite” and then wage war at the other camps. In other words, there are false dichotomies in the nutrition field. For example, someone once said that one cannot believe in food addiction and treat eating disorders at the same time. Such an interesting comment, particularly with the use of the word “believe.” In this presentation, David discusses how these topics converge and how they diverge. Mr. Wiss uses concepts of statistics to set the stage for a presentation of dialectical truths. Useful terms are defined and the broad category of nutrition for mental health is explored. This presentation is particularly useful for those who are interested in theory, and philosophical debates. Tips for assessing food addiction are offered.

Does Alcohol Affect HbA1c? Video

How does alcohol affect HbA1c?

David Wiss MS RDN describes the relationship between alcohol and glycohemoglobin (HbA1c) from a biospsychosocial perspective. Alcohol lowers HbA1c levels significantly and many researchers have concluded that alcohol is protective against T2DM. Sounds strange doesn’t it? What are the mechanisms? Is it the alcohol itself or is it people who drink alcohol? Are group differences in this relationship due to social or biological factors? Until more research is done, we have more questions than answers. Find out what we do know here and next time someone asks “does alcohol affect HbA1c?” you will be ready to chime in!

Nutrition in Recovery is a group practice of Registered Dietitian Nutritionists and other health professionals who specialize in the treatment of addictions, eating disorders, body image, mental health, as well as general wellness.

We send out a monthly Newsletter summarizing the latest research linking nutrition and mental health. Each newsletter will include a short video with some helpful hints and actions you can implement to improve mental, spiritual, and physical wellbeing for yourself and for your clients. You will be among the first to hear the findings and insights from cutting-edge data, and we are providing references so you can do your own research if interested.

Within the next year you can look forward to the following topics being covered:

Bariatric Surgery

Child Nutrition

Circadian Rhythms

Men and Eating Disorders

Nutrition Interventions Amidst an Opioid Crisis

Nutrition Interventions Amidst an Opioid Crisis

“Nutrition Interventions Amidst and Opioid Crisis: The Emerging Role of the RDN” by David Wiss MS RDN

The opioid crisis has reached epidemic proportions. The time to include nutrition into the treatment paradigm has arrived. David Wiss is not afraid to take the lead, and is doing research on this topic at the University of California, Los Angeles. 

This presentation was given at the Food and Nutrition Conference and Expo (FNCE) on Sunday October 21, 2018 in Chicago which was an invited presentation in response to the opioid crisis. Here David Wiss describes the impact of opioids on nutritional status and gastrointestinal health, identifies common disordered and dysfunctional eating patterns common to opioid-addicted populations, and describes nutrition therapy protocols for specific substances including opioids and for poly-substance abuse.

The presentation is 1:29:01 and was moderated by my dear friend and colleague Tammy Beasley, RDN. If you want to skip the video, and go straight to the slides, you can do so HERE. 

In summary, nutrition interventions have not yet been standardized or widely implemented as a treatment modality for substance use disorder (SUDs). Emphasis should be placed on gastrointestinal health, and reintroduction of foods high in fiber and antioxidants such as fruits, vegetables, whole grains, beans, nuts, and seeds. Adequate intake of protein and omega-3 essential fatty acids should be consumed daily. Regular meal patterns can help to stabilize blood sugar. Water should replace sweetened beverages. Caffeine and nicotine intake should be monitored. Dietary supplements can be very helpful in the recovery process, but should not supplant whole foods. Once nutrition behavior has improved, use of dietary supplements should be reevaluated. Lab tests and stool samples assessing gut function should provide valuable insights in upcoming years. In addition to expertise with the interaction between specific substances and nutritional status, RDNs working in treatment settings should specialize in gastrointestinal health, eating disorders, and should be current with food addiction research. There is a timely need for specialized nutrition expertise in SUD treatment settings, including outpatient clinics and “sober living” environments. Public health campaigns and specialized training programs targeting primary care physicians, mental health professionals, and other SUD treatment professionals are warranted.
