1. Background
BACKGROUND • Substance Use Disorders (SUDs) assoc. w/ vitamin & mineral deficiencies1-6 • What about altered neuro- circuitry? • Nutrition-related hormones? • Leptin, ghrelin, insulin • Gut microbiome? • We need to know more! 1.

NUTRITION AND DRUG ADDICTION • Primary Malnutrition • Displaced, reduced, compromised food intake • Secondary Malnutrition • Alterations in: • Absorption • Metabolism • Utilization • Excretion • Due to compromised health: • Oral • Gastrointestinal • Circulatory • Metabolic • Neurological Immune system Inadequate response to disease
DRUG ADDICTION VS. ALCOHOL • Negative effect of alcohol on nutritional status well-described • Protocols in place (i.e. thiamine) • Illicit drug-induced malnourishment largely unknown • Primary or secondary? • Poly-drug abuse • Ethical/legal challenges with controlled trial research • Poor patient follow-up Most data speculative, underpowered, retrospective
CURRENT CLIMATE …Little progress incorporating dietitians into drug rehabilitation programs despite continued explosion of drug abuse • Lack of interest from RDs??? • Associated stigmas of drug abuse • Difficulties conducting research on this population • Non-collaboration between public and private sector • Limited funding for new initiatives
SYSTEMS INFLUENCING FOOD INTAKE • Homeostatic System • Post-consummatory • Post-absorptive • Hedonic/Pleasure-Reward System • Consummatory • Interaction between homeostatic and hedonic mechanisms
HOMEOSTATIC SYSTEM • Key Components: • Hypothalamus • Adiposity Signals • Leptin • Insulin • Appetite-regulating gastrointestinal (GI) hormones • Orexigenic (appetite enhancing) • Anorexigenic (suppressing) • Nutrient-related signals • Vagus nerve
HEDONIC/PLEASURE-REWARD SYSTEM • Brains response to rewarding events essential for survival: • Eating behavior • Sexual behavior • Associated pleasure influences future behavior • Ensures survival as a species • Hedonic system • Drawn toward pleasurable activities • “Reward” (dopamine) • Cognitive and emotional factors
INTERACTION BETWEEN HOMEOSTATIC AND HEDONIC MECHANISMS • Homeostatic • Availability of fuel • Hedonic • Desire for and pursuit of food • “Wanting” Homeostatic signals SHOULD provide feedback to mesolimbic circuitry so that one’s metabolic state will ultimately influence the hedonic value of food…
OVERFEEDING? • Sufficient energy stores SHOULD reduce brain’s response to highly palatable food • Higher fat stores SHOULD decrease food intake and rev up metabolism • SHOULD suppress the drive to overconsume food • Modulate sensory properties • Taste, odor
HEDONIC OVERRIDES HOMEOSTATIC • Pleasurable effect of highly palatable food very MOTIVATING • “Food Motivation” • Contemporary food is supercharging our reward systems! • Hedonic drive (once provided evolutionary advantage) has now transformed into a burden
2. Food and Mood
FOOD & MOOD – Carbohydrates • Carbohydrate ingestion: • Insulin promotes the cellular uptake of glucose & amino acids (AA) (except for tryptophan) • Tryptophan brain Leyse-Wallace, R. (2008). Linking nutrition to mental health. Lincoln, NE: iUniverse.
FOOD & MOOD – Protein • AAs are the building blocks of neurotransmitters including: • Serotonin • Dopamine & Norepinephrine • Acetylcholine (inhibitory/excitatory) • Histamine (inflammatory response) • Glycine (inhibitory) Dekker, T. (2000). Nutrition & recovery. Canada: Centre for Addiction and Mental Health.
DOPAMINE • Catecholamine neurotransmitter • Dopamine is the major brain chemical involved in addiction • Important in: • Movement (muscle control) • Motivation and attention • Reward • Well-being
FOOD & MOOD – Protein • Tyrosine
FOOD & MOOD – Protein • Dopamine and norepinephrine are often associated with alcohol / drug abuse Low dopamine associated with drug abuse…(receptor dysfunction) What can mimic the reward one gets from drug use?
FOOD & MOOD – Fat • Prevalence of depression lower as fish consumption increases (omega-3)1 • Deficiencies alter fluidity in membranes affecting neurotransmission • Protective effect on bipolar, depression Omega-3 & depression is controversial2 1. Leyse-Wallace, R. (2008). Linking nutrition to mental health. Lincoln, NE: iUniverse. 2. Bloch, M. H., & Hannestad, J. (2012).

3. Substance Use Disorders (SUDs)
POLY-SUBSTANCE ABUSE • 24-hr recalls of 20 F IV drug users revealed > ½ of foods consumed not classifiable into “food groups”1 • Preference for easily ingested/digested foods (i.e. cereal) • Difficulty w/ raw vegetables & meat Digestive issues & preference for hedonistic foods rich in sugar/salt/fat 1. Baptiste, F., & Hamelin, A. (2009). Drugs and diet among women street sex workers and injection drug users in Quebec city. Canadian Journal of Urban Research, 18(2), 78-95.
POLY-SUBSTANCE ABUSE • Added sugar 30% intake of drug addicts in Norway (n=220)1 • Sugar & sugar-sweetened foods preferred > 60% of respondents • 70% vit. D deficiency • Low levels of vit. C • Elevated serum Cu 1. Saeland, M., Haugen, M., Eriksen, F. L., Wandel, M., Smehaugen, A., Bohmer, T., & Oshaug, A. (2011). High sugar consumption and poor nutrient intake among drug addicts in Oslo, Norway. British Journal of Nutrition, 105, 618- 624. doi:10.1017/S0007114510003971
OPIATES • Infrequent eating, little interest in food (appetite suppression) • Reduced gastric motility1 • Delayed gastric emptying • Impaired gastrin release • Constipation while using • Diarrhea while detoxing • GI discomfort for several months • Compromised gut health Impaired absorption of AA, vit/min 1.

Addiction, 107, 635- 641. doi:10.1111/j.1360-0443.2011.03660.x
COCAINE • Reduced appetite, nausea • Affinity for high-sugar food/drink1 • Addicts in detox prefer highest conc. of sucrose solution offered • Brain reward (dopamine) • In large national sample, cocaine users more likely to have BP than heroin or meth2 CKD or CVD 1.

Translational Research, 160(6), 391-398.
COCAINE • Low levels of omega-3 and omega-6 linked to relapse1 • May stem from increased anxiety associated w/ low PUFA2 • Addiction stripping brain EFAs3 • Impaired utilization of AAs for NT synthesis (serotonin, dopamine) • Amino acid therapy??? 1.

Grotzkyj-Giorgi, M. (2009). Nutrition and addiction – can dietary changes assist with recovery?. Drugs and Alcohol Today, 9(2), 24-28.
COCAINE – AMINO ACID THERAPY? • N-acetylcysteine (NAC) • Proposed pharmacological treatment for relapse prevention1 (animal models) • Evidence suggesting long-term efficacy of therapeutic AA programs is lacking • Need more controlled trials • Increasing overall protein can promote NT synthesis is less urgent manner • Assuming addict is safe and food is available Long-term sustainable behavior change 1.

METHAMPHETAMINE • Cessation and subsequent improvements in nutrition and oral hygiene 1st line of treatment • Oral health affects capacity to consume food, therefore… • Potential impact all areas of nutrition • Interventions must be realistic! • Monitor/evaluate xerostomia, chewing ability, and taste Consumption of refined CHO • Replace with fruits/vegetables
“SOCIAL DRUGS” CAFFEINE & NICOTINE • Used together for synergistic effects • Caffeine as cue for nicotine • Some treatment centers do not allow “social drugs,” others allow without any formal regulation • Often used as a breakfast substitute for individuals in recovery, which may have adverse effects in the afternoon1 1. Dekker, T. (2000). Nutrition and recovery. Toronto, CAN: Centre for Addiction and Mental Health.
CAFFEINE • No longer just coffee, tea, chocolate and sodas • Energy drinks, pills • Workout supplements (>300mg) • “Caffeinism” 600-750 mg/day • >1000 mg/day defined as toxic1 • DSM-5: >250 mg can be intoxicating • Coffee/tea inhibits the absorption of iron in food • Affects duration/quality of sleep 1. Hilton, T. (2007). Pharmacological issues in the management of people with mental illness and problems with alcohol and illicit drug misuse. Criminal Behavior and Mental Health, 17, 215- 224. doi:10.1002/cbm.669
Yudko, E., & McNiece, S. I., (2014). Relationship between coffee use and depression and anxiety in a population of adult polysubstance abusers. Journal of Addiction Medicine, 8(6), 438-442. • N = 69 • Mean age = 35 • Treatment center in rural Hawaii • Racially diverse • About half Pacific Islander • Coffee use associated with depression • Beck Depression Inventory • Direction of causality?
NICOTINE Nicotine • Increases metabolism1 • Acts as appetite suppressant1 • Compromises senses of taste and smell2 Smokers have tendency to choose hyperpalatable snack foods, less likely to enjoy the taste of fruits and vegetables Smokers lower in plasma vitamin C and total carotenoids, independent of dietary intake3 Introducing the vape? 1.

Nutrition and recovery. Toronto, CAN: Centre for Addiction and Mental Health.
“SOCIAL DRUG” USE – THOUGHTS • Caffeine and nicotine can impact one’s hunger/fullness cues and lead to dysfunctional eating behavior • Dietitians in treatment settings can help patients meet reduction or cessation goals when ready • By focusing on the benefits of improved physical health, patients will be positioned to make informed choices about what they eat • Strict avoidance of caffeine during early recovery may make nutrition seem punitive vs. a helpful component of recovery • “First things first” – complete avoidance may lead to relapse • Nutrition education and counseling can become an effective adjunctive approach towards caffeine/nicotine reduction/cessation
LET’S BE PRACTICAL – BIG PICTURE • Caffeine, nicotine, and hyperpalatable food may have beneficial functions in early recovery! • First issue is always to get the individual past the immediate crisis… • “Many of us have noticed a tendency to eat sweets and have found this practice beneficial.” –AA Big Book, p. 134 • Prolonged abuse after abstinence achieved may contribute to: • Comorbid conditions • Compromised quality of life • Decreased likelihood of long-term recovery • Overall healthcare burden
4. Food Addiction (FA)
“ADDICTION” – DSM-5??? • Non-Substance-Related • Gambling • Behavioral Addictions? • Sex Addiction • Exercise Addiction • Shopping Addiction • Gaming Currently insufficient evidence for diagnostic criteria What about food??? Is it substance-related? Behavioral? Both?
THE CONTROVERSY OF FOOD ADDICTION • Is overeating a behavioral problem or a substance related problem? • Does obesity stem from high-risk people or high-risk foods? • Abstinence from offending “drug foods”? • Risk factor for binge eating? • Or abstinence from offending behaviors? • Classic ED treatment
CURRENT CLIMATE • Eating disorder (ED) clinicians uneasy about incorporating FA • Classic EDs such as AN-R do not resemble an addiction • Education about FA will cause those with restrictive EDs to deepen into their ED • Challenges the classic messages: • “All foods fit” • “Everything in moderation” • “A calorie is a calorie” • “Food is fuel” Meanwhile… Standard ED treatment is associated with high rates of relapse and poor long-term remission rates1 1. Bergh, C., Callmar, M., Danemar, S., Holcke, M., Isberg, S., Leon, M., ...Sodersten, P. (2013). Effective treatment of eating disorders: Results at multiple sites. Behavioral Neuroscience, 127(6), 878-889.
MODERATION? • Perceived (vs. defined) • Self-serving biases • Justify over-consumption • Used to reduce self-conflict • Very appealing message • More part of the problem than the solution • Misinterpreted & misapplied • Big Food loves “moderation” vanDellen, M. R., Isherwood, J. C., & Delose, J. E. (2016). How do people define moderation? Appetite, 101, 156-162.
DEFINING ADDICTION & FOOD American Society of Addiction Medicine (ASAM) “addiction is a primary, chronic disease of brain reward, motivation, memory, and related circuitry” ASAM recognizes food as having addictive potential Food (Wikipedia) (Noun) Any nutritious substance that people or animals eat or drink, or that plants absorb, in order to maintain life and growth. Food in it’s natural state is hardly addictive… But what about highly concentrated by- products of food? aka processed food?
COCA LEAF VS. CRACK COCAINE Coca Leaf • Not highly addictive Powder Cocaine • By-product • Addictive Crack Cocaine • Further processed • Wreaks havoc on human brain
POPPY PLANT VS. HEROIN Poppy Plant • Not highly addictive Raw opium • By-product • Addictive Heroin • Further processed • Highly Addictive
WHEAT PLANT VS. WHITE FLOUR Wheat Plant • Not addictive Whole Wheat Flour • By-product Refined White Flour • Further Processed • “Offensive”
SUGAR CANE VS. REFINED WHITE SUGAR Sugar Cane • Not addictive Raw Sugar • By-product Refined Sugar • Further Processed • “Offensive”
CORN VS. HIGH FRUCTOSE CORN SYRUP (HFCS) Corn • Not addictive Corn Syrup • By-product HFCS • Further Processed • “Offensive”
FOOD ADDICTION • Highly processed foods that share characteristics of abused drugs1 • High dose, high concentration • Rapid rate of absorption • Most addictive combinations typically contain1 • White flour, sugar, fat (e.g. cookie) • Abundance of addictive food assoc. w/ craving & compulsion2 1. Schulte, E. M., Avena, N. M., & Gearhardt, A. N. (2015). Which foods may be addictive? The roles of processing, fat content, and glycemic load. PLoS ONE, 10(2). 2. Potenza, M. N., & Grilo, C. M. (2014). How relevant is craving to obesity and its treatment? Frontiers in Psychiatry, 5(164).
FOOD ADDICTION • Drugs addicts share many characteristics with compulsive overeaters • Brain imaging1 • Behavioral2 • “Reward” from substance • Drugs/alcohol • Hedonic food • Highly palatable food • Processed food w/ added sugars/salt/fat 1. Volkow, N. D., & Wise, R. A. (2005). How can drug addiction help us to understand obesity? Nature Neuroscience, 8(5), 555-560. 2. Davis, C., Curtis, C., Levitan, R. D., Carter, J. C., Kaplan, A. S., & Kennedy, J. L. (2011). Evidence that 'food addiction' is a valid phenotype of obesity. Appetite, 57, 711-717.
YALE FOOD ADDICTION SCALE (YFAS) • Developed in 2008, both internally & externally validated1 • Abnormal desire for sweet, salty, and fatty foods documented in obese adults using YFAS2 • Diagnostic scoring based on seven symptoms in the DSM-IV-TR for substance dependence • Withdrawal • Tolerance • Use despite negative consequences • Food addiction found in 57% of obese BED patients3 1.

T., Crosby, R. D., & Grilo, C. M. (2012). An examination of the food addiction construct in obese patients with binge eating disorder. International Journal of Eating Disorders, 45, 657-663.
FOOD ADDICTION – CULPRITS …Sugar, Salt, Fat + dynamic contrast • The more multisensory the food the more likely a person is to crave it • Combining a cold food such as ice cream with a warm sauce such as hot fudge, and topping it off with smooth Reese’s peanut butter cups and crunchy heath bar pieces becomes irresistible
FOOD ADDICTION – CULPRITS Refined grains… w/ sugar/salt/fat
FOOD ADDICTION – CULPRITS What is the difference between a baked potato and French fries with ketchup? Fat…Salt…Sugar
Schulte, E. M., Avena, N. M., & Gearhardt, A. N. (2015). Which foods may be addictive? The roles of processing, fat content, and glycemic load. PLoS ONE, 10(2). 1. Chocolate 2. Ice Cream 3. French Fries 4. Pizza 5. Cookie 6. Cake 7. Popcorn (Buttered) 8. Cheeseburger
WHAT IS A “FOOD ENVIRONMENT”? • Collection of physical, biological, and social factors affecting eating habits/patterns • Access to food • “Food Deserts” convenience foods • Resource limitations? • Food availability at home (rehab) • Environmental causes of overeating? • Highly available “hyperpalatable” foods a risk factor for food addiction in some individuals? • “Big Food” aka The Food Industry created irresistible, yet toxic “Food Environment”?
WITHDRAWAL – ANIMAL MODELS • Rats w/ access to highly palatable cafeteria diet for 40 days • When taken off, they reject standard chow! • Chronic exposure to addictive substances causes self- administration of excess in attempt to regain the same hedonic level (subjective pleasure) Cottone, P., Sabino, V., & Steardo, L. (2008). Opioid-dependent anticipatory negative contrast and binge-like eating in rats with limited access to highly preferred food. Neuropsychopharmacology, 33, 524-535.
BED vs. FOOD ADDICTION Binge Eating Disorder • Ate the whole box of chocolates in one sitting • Psychological/emotional • DSM-5 clinical diagnosis, insurance reimbursement Food Addiction • Ate the whole box over several sittings • Biological/neurochemical • Not recognized or reimbursable There are more similarities than there are differences… Obesity can exist without either one!
FOOD ADDICTION • Reward-responsive phenotype of obesity1 • Can exist without obesity2 • And without BED • Food becomes less rewarding and more habitual3 • Alterations in dopamine circuitry • Low levels of DA transmission linked w/ heightened propensities towards substance abuse in bulimic women4 1.

(2012). Food and drug reward: Overlapping circuits in human obesity and addiction. Current Topics in Behavioral Neurosciences, 11, 1-24.
REWARD SURFEIT THEORY • Individuals w/ greater reward region sensitivity to food intake at elevated risk for overeating • Habitual intake of palatable foods leads to hyper- responsivity of attention and reward valuation Val-Laillet, D., Aarts, E., Weber, B., Ferrari, M., Quaresima, V., Stoeckel, L. E., …Stice, E. (2015). Neuroimaging and neuromodulation approaches to study eating behavior and prevent and treat eating disorders and obesity. Neuroimage: Clinical, 8, 1-31.
PHARMACOLOGY • Animal models: • Naltrexone reduces food intake1 • Opioid system: • Medial PFC regions • Involved in the control of feeding behavior • Key mediator of hedonic feeding • May be responsible for hyper-evaluation of highly palatable foods • Varenicline reduces sucrose consumption2 • Long-term 1.

Psychiatry Research, 229, 126-132.
GHRELIN • Stimulates appetite • Decreases after eating • Opposing effects with leptin • Leptin counters ghrelin • Stomach-derived • Receptors identified in VTA, hippocampus, amygdala1 • Sight of food elevates ghrelin2 • Non-obese healthy subjects 1. Dagher, A (2012). Hunger, hunger, and food addiction. In Brownell, K. D., & Gold, M. S., Food and addiction (131-137). New York, NY: Oxford University Press. 2.

INSULIN • Peptide hormone from pancreas • Similarities to leptin: • Anorexigenic • Adiposity signal • Attenuates food reward • When low, drive for food intake increases • Works with dopamine to calibrate reward associated with feeding1 • Depresses dopamine conc. in VTA, which may suppress salience of food once satiety is reached 1. Mebel, D. M., Wong, J. C. Y., Dong, Y. J., & Borgland, S. L. (2012). Insulin in the ventral tegmental area reduces hedonic feeding and suppresses dopamine concentration via increased reuptake. Behavioral Neuroscience, 36, 2336-2346.

Advance online publication. Retrieved from http://dx.doi.org/10.1016/j.appet.2013.07.011 • Cocaine-dependent men reported increased food intake, specifically foods high in fat and carbohydrate • Trend towards lower levels of circulating leptin in the cocaine group, directly interfering with metabolic processes • Overeating in cocaine-dependent individuals pre-dates recovery, with the effect masked by lack of weight gain • Taken together, cocaine abuse results in imbalance between fat intake and storage, leading to excessive weight gain during recovery
HORMONES – DISCUSSION • Food and drugs compete for overlapping reward mechanisms • When substance abstinence has been achieved, likely a compensatory increased drive for food • Ravenous “rebound appetite” • Hypothalamus
HORMONES – DISCUSSION • Normalizing disrupted leptin signaling cascade may be sufficient to decrease motivation for food reward • Weight gain during addiction recovery should be monitored/controlled in order to counter associated hormonal adaptions • Exposure to highly palatable
7. Gut Microbiome
BURNING QUESTIONS • Why are so many of us drawn to foods that can compromise our quality of life? • Why do some of us reject foods that can heal us? • Why are educational efforts alone often not sufficient to produce sustainable behavior change? • Why is it so challenging to develop a new relationship to food? Lack of willpower? Food addiction? Restrained eating? Dieting?

8. Nutrition Therapy
NUTRITION INTERVENTIONS – GOALS • Primary goal is to support recovery by any means necessary • Complete abstinence from all illicit mind-altering substances • Nutrition therapy emphasizing correction of nutrient deficiencies • Lab data to warrant aggressive interventions
NUTRITION INTERVENTIONS – GOALS • Immediately bombarding an addict entering treatment with pills and other supplements may fail to support behavioral aspects of recovery • If individuals begin using again, efforts to correct nutritional deficiencies are futile, and are likely to redevelop!
SUPPLEMENTS VS. FOOD • Supplements may give patients the idea that as long as they take pills, they do not need to improve their eating habits • Street drugs exert tremendous strain on liver supraphysiological doses of nutrients may actually conflict with healing process • Eating behavior FIRST, supplements SECOND
IDEAL TIMELINE – NUTRITION THERAPY • 6 hours • Complete diet liberalization • Micronutrient supplementation • 6 days • Targeted nutrition education • Diet liberalization (goal: improvement) • 6 weeks • Reduce intake of sugar and refined CHO • 6 months • Cessation of supplementation
SO WHAT ARE YOU SAYING? • Liberalized diet including abnormal amounts of sugar during first weeks of abstinence can assuage painful symptoms of withdrawal • Consumption behavior should be monitored and eventually sugar use should be reduced • Assessed individually
NUTRITION INTERVENTIONS • “Western Diet” – PROBLEM • Low in fiber • High in sugar and/or AS • High in inflammatory fats • Omega-6 and certain saturated fats • Nutrition in Recovery – SOLUTION • High in fiber • Low in sugar, no AS • High in anti-inflammatory omega-3s • Lower in pro-inflammatory omega-6 Priority #1 Transitions are typically gradual & progressive. Gut will hardly allow for anything else!
THE IMPORTANCE OF FIBER • Gradual/progressive reintroduction • Low fiber tolerance creates significant barriers for nutrition therapy involving fruits, vegetables, whole grains, beans • Increase 2-4 g/week to meet recs: • 38 g/day men, 25 g/day women • Ages 14-50 Focus on improved gut health • Optimal absorption of AAs, vits/mins
INTERVENTIONS – FIBER • Get fiber from food, not from fiber supplements! • Fruits • Vegetables – emphasize raw • Whole grains • Beans • Nuts/seeds – emphasize raw • Eat a wide range of plant foods on a daily basis • F or V with every meal/snack Every time you eat: Fiber Fat Protein
OPERATION: HEAL THE GUT! • Gut-Brain Communication1 • Brain-Gut (Bi-Directional) “Psychological treatments are known to improve functional gastrointestinal disorders, the next wave of research may involve preventative microbiological gut based treatments for primary psychological presentations…” 1.

Australian & New Zealand Journal of Psychiatry, 49(3), 207- 214.
INTERVENTIONS – BEVERAGES • Eliminate artificial sweeteners • And artificial colors • Stop consuming sweetened beverages. Yes, all of them! • Beverage list: • Water • Chia water • Tea (unsweetened) • Black coffee? • Milk (organic only) • Alt. milk? (unsweet, carrag. free) Negative impact of (short- term) artificial sweeteners on gut microbiota reversed w/in 2-8 weeks1 1. Suez, J., Zilberman-Schapira, G., Segal, E., & Elinav, E. (2015).

SUMMARY – NUTRITION THERAPY • Nutritional deficiency lowers antioxidant potential of cells • Increased potential for cell damage • Increased need for antioxidant vitamins A, C, E, selenium • Higher protein needs than the general population • Promote neurotransmitter synthesis
WHAT ABOUT EXERCISE? Lifestyle interventions involving both diet and exercise • Exercise supported in treatment of mental illness1 with profound impacts on cognitive abilities2 • Aerobic activity transforms not only body but mind2 • Exercise can help rebuild brain cells killed by alcohol- ten min. of exercise could blunt an alcoholic’s craving2 • Other benefits: • Increased self-esteem, self-efficacy • Elevated mood • Improved energy and concentration • More relaxing sleep • Relief of tension • NORMALIZE HORMONES Integration of exercise along w/ nutrition critical for full recovery from substance abuse 1.

EXERCISE PROTOCOLS • Strength training • GI tract is made of muscles • Twice/week • Cardio • Outdoors whenever possible • Twice/week • Yoga • Aids in digestion (parasympathetic nervous system) • Basically helps with EVERYTHING • Twice/week
BIG PICTURE – GOALS • Not necessarily weight loss • Relapse prevention • Disease prevention • Focus on overall health • Body, mind, spirit • Behavior change & self-efficacy • “Sanity restoration” • “Recovery” • Can be difficult to measure Eventually developing a relationship w/ food & exercise that is intuitive/personal • Avoid “quick fix” whenever possible
BIG PICTURE – GOALS • Cooking Classes • Mandatory part of treatment! • Life Skills • Grocery shopping • Food safety • Meal planning • Kitchen cleaning • Challenge the entitlement
FOOD ADDICTION • Recent meta-analysis1 • 20% of all subjects tested for FA met criteria • No well-accepted treatment • Abstinence from addictive food? • Mindfulness? Intuitive Eating? • Health at Every Size? • Psychiatric interventions? • Surgical interventions? 1. Pursey, K. M., Stanwell, P., Gearhardt, A. N., Collins, C. E., Burrows, T. L. (2014). The prevalence of food addiction as assessed by the Yale food addiction scale: A systematic review. Nutrients, 6, 4552-4590.
GOOD VS. BAD FOODS? • As an eating disorder specialist, this simplistic distinction can cause more harm than good • Cognitive distortion • HOWEVER, we can start to discern between: • Real food vs. processed food • Non-addictive vs. addictive food • Gut healing vs. gut harming • If it has the potential to promote dysbiosis, think twice! “Everyone knows how important the brain is. We have all sorts of educational protocols in place for the brain. But what about the second brain? If the gut truly is the second brain, we need educational protocols for the gut.” David Wiss MS RDN Nutrition in Recovery
ABSTINENCE FROM OFFENDING FOODS??? • Some food addicts do benefit from restricting added sugars, refined grains, fried foods… • Beware of rebound bingeing vs. • Disordered thinking patterns • “Orthorexia”
HOW TO END FOOD ADDICTION Take Care of Yourself: • Regular meals/snacks • Plenty of water • Minimal caffeine • Daily exercise • Something you enjoy • Modulates reward pathway • Sufficient quality sleep • Support system • Give up on perfectionism
HOW TO END FOOD ADDICTION • Reconnect with food • Intuitive Eating • Attuned Eating • Mindful Eating • Stop multitasking at meals • Only eat table • Pay attention (non-judgmentally) • Focus on each mouthful • Chew and savor • Put down cutlery between bites • Quality not quantity • Prepare your own food
INTERVENTIONS – “INTUITIVE EATING” • Can we trust our body wisdom? • Near gut homeostasis • Low addictive symptomatology • Hormonal milieu relatively stable • Mindfulness training YES – in sync with intuition • Gut dysbiosis • Addiction/withdrawal/craving • Hormonal extremes • Mindless eating NO – addiction running the show Guarner et al. (2003)
9. Conclusions
CONCLUSIONS • Restoration of nutritional status in SUD should look beyond vitamin/mineral status and body weight! • Goals should include BEHAVIORS: • Gut (HOT TOPIC!!!) • Brain chemistry • Hormones Minimize spikes/drops in insulin
NUTRITIONAL TREATMENT • Must consider biology: • A calorie is NOT a calorie • It is “about the food” • Food industry continues to deny responsibility, always stressing individual responsibility for eating, and pointing to lack of exercise • Psychological interventions alone are not sufficient • Educational efforts alone are not sufficient (just like drug addiction) Gut, brain, endocrine system
TREATMENT-BASED EVIDENCE • Most people report that eating less “processed foods” & more “whole foods” improves wellness & mood • Impact more pronounced in some • But we never really knew WHY... UNTIL NOW? • Many highly processed foods have ingredients that negatively impact gut microbiota!
THE ROLE OF THE DIETITIAN • Dietary intake • Nutritional needs • Regular feeding patterns • Healthy weight goal • Food fears, restrictions, rules • Feelings/emotions around food • Medical nutrition therapy
WHAT IS YOUR FOOD PHILOSOPHY? “All foods fit. But not all foods fit for all people. And just because the food industry manufactures and sells it, does not mean we have to include it.”
WHAT CAN THE RDN DO AS A MEMBER OF THE TREATMENT TEAM? Every patient who walks into substance abuse treatment should be assessed by a dietitian!!! • Screen for ED and other dysfunctional/disordered food behaviors • Request nutrition-related labs for high-risk patients • Run groups and offer individual counseling (Nutrition Therapy) • Collect data and publish findings (that means YOU!) • Develop educational curriculum, life skills experiential therapies • Plan special events ex: Supermarket Tours • Attend treatment planning and staff meetings • Work w/ doctors/therapists/counselors to help achieve treatment goals • Nutrition/exercise interventions to facilitate behavior change favorable to long-term recovery and improved quality of life • Audit the menu and suggest substitutions within the budget • Food service and food safety improvements • Work with the chef to improve the “food environment”
WHAT’S NEXT? • RDN integrated member of the treatment team! • Individual counseling • Educational groups • Approves all food/beverage • Meal/snack planning • Supermarket tours & meal outings • Treatment planning
