Nutrition For Addiction Recovery

A life of sobriety involves more than just abstinence from drugs. It’s about creating a healthy lifestyle that supports physical, emotional, and mental wellness. The effects of addiction reach every aspect of life, and each of these needs to heal to build strong recovery. This includes paying attention to the eating habits that became second nature during active substance abuse. 

You will need a well-functioning body to carry you forward in your journey of sobriety. Healthy Life Recovery provides a thorough recovery program that includes up-to-date nutrition education. Our clients can customize their diets for their own nutritional goals.

Malnutrition with alcoholics and addicts comes from a lifestyle that’s a standard part of substance abuse. It also results from damage biochemically caused by the substances themselves. Nutrition is a low priority in a user’s life.

Addicts typically tend to see food more as a burden or pastime instead of a source of essential nutrients. Because of this, food choices are based largely on flavor, what’s most convenient, or what’s cheapest, not what’s most nutritionally sound. That often means the decision is fast food, sweets, and junk food.

An addict’s lifestyle consists of not only poor eating habits but also a lack of exercise and irregular sleep patterns, leaving their bodies in a very unhealthy state. Many people who enter treatment haven’t paid attention to their nutrition for years or may have never learned how to eat healthily. Some came from homes where good eating habits were hardly supported. 

People who have abused drugs feel awful when they stop using drugs. This is partly because drugs or alcohol covered the symptoms of the body’s malnutrition state. In recovery, headaches, nausea, mental illness, low energy levels, and sleep disturbances do not only come from withdrawal, but also poor nutrition. Without proper vitamins and nutrients, the damage extends to hormones, organs, nerves, and glands.

Addiction & its Impact on Nutrition

How addiction impacts nutrition:

  • You eat less or not at all – Alcohol and most narcotics suppress the appetite, and the drug itself replaces the nutrition the body needs.
  • You eat lower quality food – Satisfying the cravings of addiction becomes the top priority. Eating nutritionally sound meals is hardly a concern.
  • Overeating – Marijuana addicts tend to overeat, which leads to severe weight gain and all the conditions that come with excessive body fat.
  • Damage to organs – Drug addiction can lead to damage to the pancreas, gastrointestinal tract, the lining of the stomach, and the liver. Damage to these organs leads to problems in digestion, nutrition storage, and nutrient absorption.
  • Suppressed immune system – Drugs and alcohol can damage the immune system leaving you with little defense against illnesses and infections.

Malnutrition could also make your recovery more difficult because you can be more mentally vulnerable to anxiety, short attention spans, depression, low energy, and cravings. Food affects the brain. There is a very close connection between substance abuse, mood, and nutrition.

Hormones related to digestion can trigger pleasurable or unpleasant emotions in the brain. When your brain doesn’t have enough nutrients, its levels of neurotransmitters are off-balance, leaving you with depression, agitation, and stress. These unregulated mood states can be triggers for relapse.

Comfort eating, also known as “eating your feelings,” is when an individual uses food to cope with their emotions, not because they are hungry. Addicts are accustomed to turning to anything that helps them escape from uncomfortable feelings. Food eaten for comfort tends to be sweets and junk food. This pattern leads to out-of-control weight gain and lethargy, which leave you ultimately feeling worse. 

This creates a cycle leading to more comfort eating to soothe its own consequences. Food, especially sugar, can become a cross-addiction, giving the recovering addict a mild high with a dopamine release – a small version of what they had when they were getting high. This pattern makes it more difficult for a person to stay positive and motivated, leading to a potential for relapse. Comfort eating can become a temporary way of coping with reality, that is ultimately maladaptive and self-defeating.

The recovering addict needs to engage in the empowering activity of taking control of their nutrition and be proactive with their self-esteem by making decisions that improve their quality of life. You may feel sick and tired of your addiction, but don’t leave your body feeling sick and tired with inadequate nutrition.

Better Nutrition

The benefits of better nutrition include:

  • A better, more stable mood
  • Higher energy level
  • Better focus, longer attention span
  • A stronger immunity
  • Repairs damage to organs and tissues
  • Build self-care habits and create a healthy lifestyle

Thorough recovery involves more than a group or individual therapy, learning new coping mechanisms, spotting triggers, or understanding emotional regulation. Those in recovery need a balanced approach that gives your body the necessary elements for a healthy life through nutrition education.

Nutrition & Substance Abuse


Alcohol affects the entire body. Heavy alcohol abuse physically damages major organs. Alcohol consumption also tends to replace eating, leaving the body starved of essential nutrients and functionally incapable of effective digestion.  Some alcoholics take up to 50 percent of their daily caloric intake from alcohol. Alcohol has calories, but no nutrients. When alcohol replaces food in your diet, you’re not taking in the nutrients your body needs, which amplifies the toxic effects of alcohol.

Alcoholics suffer from a depletion in vitamins in the B-complex group, namely B6, B12, thiamine, and folate, all of which are involved in neurological health. They also have notable deficiencies in vitamins A, C, D, K, also minerals – zinc, calcium, phosphorus, and magnesium. Magnesium is needed for around 300 biochemical reactions in the body. Zinc deficiency causes reduced night vision, facial skin sores, and a lower sense of taste and smell. Low zinc levels are also associated with depression, confusion, irritability, and apathy. Thiamine deficiency is especially problematic because it is a foundational component of all tissues in the body.

Inadequate thiamine levels affect the functionality of the heart, leaving you open to heart disease. Thiamine also influences the brain and could leave the alcoholic liable to dementia, loss of coordination, vision problems, memory loss, and confusion. Alcohol abuse could also lead to Metabolic Syndrome, which results in high blood pressure, high cholesterol, high blood sugar, increase risk of heart disease, hypertension, and diabetes. Deficiencies in B-complex nutrients could also result in Wernicke-Korsakoff syndrome, characterized by lowered cognitive function, including memory loss and lack of muscle coordination.

A high level of alcohol intake damages the liver, whose roles are to produce proteins and to eliminate toxins. The damage to the liver makes it less capable of absorbing much-needed calcium, eventually leading to cirrhosis. Alcohol also affects the pancreas, which is responsible for regulating blood sugar levels and producing digestive enzymes. These enzymes help the digestion of fats, proteins, carbohydrates, and hormones that balance blood sugar levels. With a dysregulated blood sugar level, alcoholics are susceptible to type 2 diabetes and obesity.

The high levels of abdominal fat can lead to heart disease, high cholesterol, and an elevated risk of heart attack and stroke. Changes in blood sugar common with alcoholism have been shown to increase alcohol cravings. Damage to the stomach lining interferes with the breakdown and absorption of nutrients. You may end up with low energy levels and a weaker immune system, leaving you wide open to diseases and infections. Eventually, dental problems could arise along with skin conditions, even changes in the way food tastes. In the long term, risks include brain damage, nerve damage, liver disease, heart disease, pancreas problems, and some forms of cancer.


Opioids include all naturally and synthetically derived drugs that are chemically based on opium. This includes heroin and medications like oxycodone (Percocet, Oxycontin), hydrocodone (Norco, Vicodin), hydromorphone (Dilaudid), fentanyl, morphine, codeine, and methadone. Opioids act on the central nervous system and slow all the body’s movements, including digestion and metabolism. The effects of long-term opioid abuse on nutrition include chronic constipation, loss of appetite, and the inability to absorb nutrients. 

Those withdrawing from opioids experience symptoms like diarrhea, nausea, vomiting. These symptoms lead to dehydration, loss of nutrients, and imbalances of electrolytes such as potassium, sodium, and chloride. 

Many opioid abusers report intense sugar cravings. Sugar addiction can contribute to a biochemical state that perpetuates opioid dependence. Those in recovery should dramatically reduce sugar intake to eliminate this reward pathway.

Dual Diagnosis


This category consists of crystal methamphetamine, cocaine, and ADHD medication. Most people who abuse stimulants don’t feel hungry. They are left malnourished and underweight. Stimulants are closely associated with eating disorders like anorexia or binge eating after a run of heavy use. Other effects include memory loss, malnutrition, anxiety, paranoia, and insomnia. Stimulants speed up the activities of the brain and nerves and charge up the body’s metabolic rate. 

Those whose drug of choice is a stimulant enter treatment underweight, dehydrated, and muscular deficient. Many times they lack vitamin A, vitamin C, the B vitamins, and iron, including electrolytes like calcium and potassium. Stimulant abuse often leads to a deficiency in omega-3 fatty acids, which contribute to the regulation of mood and the prevention of depression and anxiety.


One of the chemical compounds of marijuana, tetrahydrocannabinol (THC), ignites the appetite. Even the average user gains excessive weight as they commonly crave sugary, high-fat junk food while they are under the influence. Binge eating, or “having the munchies,” is a well-known part of using marijuana. 

The super-charged appetite and high caloric intakes come with the standard set of consequences of uncontrolled eating. This includes a host of risks: excessive weight gain, heart disease, high blood pressure, stroke, diabetes, cancer, and sleep apnea.

Essential Nutrition

Vitamins and Minerals

Vitamins and minerals are two main types of micro-nutrients with specific roles to keep your body functioning correctly. Inadequate amounts of vitamins and minerals can have serious side effects. A lack of thiamine (vitamin B-1) may lead to Wernicke-Korsakoff syndrome.  Low levels of iron, folate, or B vitamins can result in symptoms like depression, fatigue, poor attention, and sleep disturbances. Healthy sources of vitamins and minerals include fruits, vegetables, seeds, beans, peas, dairy, peanuts, and whole-grain bread or cereal.



Carbohydrates are macronutrients that provide the body with energy, help with brain function, and keep blood sugar stable. Eating food with complex carbohydrates like bread, pasta, root vegetables (potatoes, carrots), legumes (beans, lentils, peas) helps regulate levels of serotonin in the brain.  Serotonin supports a positive, stable mood, and assists with healthy sleep cycles. Carbohydrate intake releases insulin that is used for energy and helps tryptophan enter the brain. Folic acid and vitamins B6 and B12 assist the synthesis of tryptophan to serotonin. Reliable sources of carbohydrates include nuts, beans, vegetables, potatoes, whole fruit, and low-fat dairy.



Fiber is a type of carbohydrate that lowers blood cholesterol and helps regulate blood sugar. Fiber also enables food to move through the digestive system. Fiber relieves constipation, which is symptomatic of opiate abuse. High blood sugar and dangerous cholesterol levels can come from a diet low in fiber. Healthy sources of fiber include tomatoes, nuts, oatmeal, carrots, apples, nuts, beans, brown rice, and wheat bread.



Protein builds and repairs every cell in the body. It is vital for muscle and connective tissue. Protein also helps produce hormones and neurotransmitters. Amino acids are the building blocks of proteins and are crucial to neurotransmitters. A lack of neurotransmitters, especially dopamine and serotonin, can trigger an individual to find relief by returning to substance abuse.  The immune system’s strength depends mostly on protein intake. While many drugs weaken the immune system, a diet low in protein doubles the problem and cripples the immune system. Good sources of protein include nuts, beans, low-fat dairy, eggs, fish, and chicken.



Dietary fat is a reserve source of energy, but also plays a role in producing hormones, supporting the nervous system, and building cell membranes. Although many try to reduce fat in their diets, not all fat intake is unhealthy. There are fats that the body needs but can’t produce on its own. These are known as ‘essential fatty acids.’  Omega-3 and omega-6 fatty acids help keep the production and activity of neurotransmitters smooth, and therefore directly influence mood. A diet with excessive unhealthy fat can result in obesity and a host of health problems. Some good sources of dietary fat include nuts, olive oil, seeds, dairy, and fish.



Water is an indispensable staple for a healthy diet. The liver and kidneys use water to perform their functions. Water prevents constipation, lubricates joints, protects internal organs, and aids in the absorption of other nutrients. Dehydration can lead to disorientation, trouble concentrating, and irritability. Dehydration can arise during the detox process, and it is even more imperative that those in early recovery take in enough fluids.

Fueling Your Recovery

Vitamins and Minerals

Several factors influence a person’s desire to stick with long-term sobriety. These factors can be positively strengthened by maintaining a healthy diet but can be negatively affected by poor nutrition.

Energy, motivation, and resilience – starting a new life of sobriety come with many personal challenges and obstacles. It takes effort and perseverance to build new habits and coping mechanisms.  Healthy eating can supply the energy and drive to face all the necessary life adjustments. Malnutrition can leave you feeling heavy and weighed down. You will feel drained of strength to keep forward progress.
Attention and focus – Recovery is a process of becoming aware of yourself and your environment. It’s a process of paying attention to new information and opening your awareness to what’s going on within. Proper nutrition will support strong attention spans.

A healthy diet will help you focus and process what you’re learning about yourself on a deeper level. Poor eating habits leave you easily distracted and mentally cloudy. It’s a state that’s not conducive to learning a new way to think and live.

Self-confidence, mood, and self-esteem – a positive sense of self-worth strengthens your drive to face life’s challenges. You’ll realize that you’re worthy of a sober, healthy life. You’ll feel capable of using the tools of recovery to build the kind of productive life you’ve always wanted. Balanced eating habits give your mood stability, while malnutrition makes your body feel the weight of depression and anxiety.
Ability to face cravings and overcome them – Cravings and temptations to relapse are normal parts of recovering from substance abuse. Resisting these cravings takes emotional and physical stamina. Malnutrition and vitamin deficiencies will intensify cravings and give you the illusion that you need to get high or drunk to feel better. The more mentally and physically healthy you are, the easier it is to remember that you don’t need to turn to drugs or alcohol to make it through life.
