Food Addiction and Mental Health

Food Addiction and Mental Health (Adult Population)

Food addiction is commonly described as a pattern of compulsive overeating and intense cravings for highly palatable foods, where a person continues to eat in an “addiction-like” way despite negative physical, emotional, or social consequences. It typically involves strong, recurring cravings for specific foods, often those high in sugar, fat, and salt; loss of control over eating, such as eating more than intended or being unable to cut down despite repeated efforts; and continued overeating even when aware of harm (weight gain, health problems, distress), similar to substance use disorders. The Food Addiction and Mental Health Research Category explores the complex interplay between dietary behaviors, neurobiological reward systems, and psychological well-being, highlighting how compulsive eating patterns influence — and are influenced by — mental health conditions.

Dopamine D2 receptor modulation of insulin receptor signaling in the central amygdala: implications for compulsive-like eating behavior

  • Reviewed By CNP Staff

Compulsive eating behavior, defined as the excessive consumption of palatable, high-sugar, high-fat foods despite negative consequences, may be linked to dysfunction in the dopamine system, particularly involving dopamine D2 receptors (D2Rs). This research demonstrates that D2Rs regulate insulin receptor (InsR) signaling in the central amygdala (CeA), a mechanism crucial for the persistence of compulsive-like food-seeking […]

  • Reviewed By CNP STAFF

This 2021 article points out that there have been mixed results on the effects of nonnutritive sweeteners (alternative to nutritive sweeteners that quench the desire for sweets while providing fewer calories) on appetite. It is unknown how sex and obesity correlate with the reward and appetitive responses to nonnutritive sweeteners (NNS). One of this study’s […]
