Food craving
Encyclopedia
A food craving is an intense desire to consume a specific food, stronger than simply normal hunger
Hunger
Hunger is the most commonly used term to describe the social condition of people who frequently experience the physical sensation of desiring food.-Malnutrition, famine, starvation:...

. According to Marcia Levin Pelchat "It may be the way in which foods are consumed (e.g. alternating access and restriction) rather than their sensory properties that leads to an addictive eating pattern."

Causes

There is no single explanation for food cravings, and explanations range from low serotonin
Serotonin
Serotonin or 5-hydroxytryptamine is a monoamine neurotransmitter. Biochemically derived from tryptophan, serotonin is primarily found in the gastrointestinal tract, platelets, and in the central nervous system of animals including humans...

Endorphin
Endorphins are endogenous opioid peptides that function as neurotransmitters. They are produced by the pituitary gland and the hypothalamus in vertebrates during exercise, excitement, pain, consumption of spicy food, love and orgasm, and they resemble the opiates in their abilities to produce...

Fat

s and carbohydrate
Carbohydrate
A carbohydrate is an organic compound with the empirical formula ; that is, consists only of carbon, hydrogen, and oxygen, with a hydrogen:oxygen atom ratio of 2:1 . However, there are exceptions to this. One common example would be deoxyribose, a component of DNA, which has the empirical...

, such as chocolate, are more frequently craved than foods with lower sugar glucose, such as broccoli because when glucose interacts with opiod system in the brain an addictive triggering effect occurs. The consumer of the glucose feels the urge to consume more glucose, much like an alcoholic, because the brain has become conditioned to release "happy hormones" every time glucose is present.

The craving of non-food items as food is called pica

Taste Addiction Disorder

Taste addiction disorder is a psychological condition with a biochemical basis in the brain where a person develops an obsessive/compulsive relationship to food. Certain foods are craved more than others because of their glucose content. When the glucose level rises, the brain produces more dopamine, which drenches the brain in "happy hormones". Over time a person can become addicted to the release of the dopamine because this may be their only way of attaining this feeling. Other ways of giving the brain a dopamine bath include, but are not limited to, singing, running, dancing, laughing with other people, or engaging in sex. TAD functions biochemically in a parallel way to other compulsive behavior addictions such as alcoholism, drug addiction, anorexia, bulimia, and sex addiction.

Biochemical basis

Addiction to certain foods has a biochemical basis and evidence because according to the research of Avena and her colleagues "Neural adaptations include changes in dopamine and opioid receptor binding, enkephalin mRNA expression and dopamine and acetylcholine release in the nucleus accumbens." This essentially means that the brain physically changes when it becomes used to consuming a mass quantity of a certain chemical so that the brain can release the highest quantity of dopamine possible.

Social basis

In many ways, T.A.D. is a biochemical manifestation of a social issue. Humans' addiction to food is the result of general negativity surrounding food. The trend towards viewing food as 1. a possession rather than nourishment, 2. a chore to consume quickly rather than a source of energy to absorb, or 3. a finished product which brings instant gratification rather than a cultivated meal which gradually is taken in. These changes in viewing food cause people to feel guilty for enjoying food. These notions stigmatize eating for a long period of time. This build up of the notion that "food is bad", that "food is the enemy" leads to food obsession. This is the gateway to food addiction. The following are a list of suggestions to fight the status quo of food negativity in favor of "food positivity".
  • Eat family style - communally, slowly, at a table
  • Eat Slowly
  • Eat locally and avoid fast food
  • Take time each day to appreciate food and water
  • Avoid eating on the go by dining at regular times
  • Eat everything in moderation
