Dear Readers,

Many of us know someone who has struggled with an addiction. Perhaps they have tried to quit smoking or are addicted to drugs like heroin or methamphetamine. The American Psychiatric Association defines addiction as a complex condition, a brain disease that is manifested by compulsive substance use despite harmful consequence. [1]. Does substance addiction include food? Although food addiction is not included in the DSM (Diagnostic and Statistical Manual for Mental Disorders), it is estimated that as many 20 percent of Americans struggle with some type of food compulsion. [2]

One may automatically assume that food addiction only affects those who are overweight; however, the scientific literature shows otherwise. While some individuals with obesity may display behaviors similar to individuals addicted to drugs [3], estimates suggest that only approximately 24.9% of overweight/obese individuals report clinically-significant symptoms of food addiction and 11.1% of healthy-weight individuals also report these symptoms [2]. 

The topic of food addiction is controversial in the medical field. One criticism is the addictive ingredient has not been identified. It has been proposed that highly processed, highly palatable foods containing large amounts of fat and sugar can be addictive for some individuals. But what exactly is in these foods that leads to addiction? One does not typically consume sugar or butter by itself, which makes identifying the addictive agent difficult.

Studies have found parallels between food addiction and other substance abuse disorders, such as opioid addiction. Some of these include:

  1. Changes in brain chemistry in response to the substance. For example, dopamine is released in response to certain foods. Dopamine is a chemical that plays a role in the reward center in our brain and allows us to feel a sense of pleasure. If we experience pleasure and reward, we are likely to repeat the behavior, maybe even to a point that it is no longer good for us.
  2. Preoccupation with the substance. One may obsess about a particular food, feel deprived of happiness in the absence of this food, or may experience cravings.
  3. Impaired control. Once the substance or food is taken in, it is difficult to maintain control of how much is used.
  4. Social impairments. This includes changes in your social activities for the sake of the addiction. For example, a person binges on a certain food, then spends hours exercising to burn off those calories rather than spending time with family and friends. 

What do you do if you have a food addiction? If you can completely abstain from the problem food, that is your best defense. It may be difficult to completely abstain from sugar since it is in so many foods. You can abstain from sweets or avoid foods with 5 grams of sugar or more per serving.

Another solution is a 12-step program, Overeaters Anonymous, aimed at helping those with food addictions and eating disorders. Theirs is a spiritual, not religious, program similar to that of Alcoholics Anonymous. Go to oa.org or call (505) 891-2664 to find a meeting near you.
