The idea that a person can be addicted to food has recently gained credibility and support from scientific research.
Experiments in animals and humans show that, for some people, the same reward and pleasure centres of the brain that are triggered by addictive drugs like cocaine and heroin are also activated by food, especially highly palatable foods. Highly palatable foods are foods rich in:
Sugar, Fat, Salt
Like addictive drugs, highly palatable foods trigger feel-good brain chemicals such as dopamine. Once people experience pleasure associated with increased dopamine transmission in the brain's reward pathway from eating certain foods, they quickly feel the need to eat again.
The reward signals from highly palatable foods may override other signals of fullness and satisfaction. As a result, people keep eating, even when they're not hungry.
People who show signs of food addiction may also develop a tolerance to food. They eat more and more, only to find that food satisfies them less and less.
Scientists believe that food addiction may play an important role in obesity. But normal-weight people may also struggle with food addiction. Their bodies may simply be genetically programmed to better handle the extra calories they take in. Or they may increase their physical activity to compensate for overeating.
People who are addicted to food will continue to eat despite negative consequences, such as weight gain or damaged relationships. And like people who are addicted to drugs or gambling, people who are addicted to food will have trouble stopping their behaviour, even if they want to or have tried many times to cut back.
