Consumption of fatty and high-calorie foods leads to similar processes of drug addiction.
Frequent consumption of high-calorie foods, chips, chocolate products and carbonated beverages creates in the body a constant desire to absorb sugar, salt and fat . According to scientists, over time, the pleasure of consuming such foods decreases, and to meet our needs, we increase the amount of food consumed.
Experts define the observed behavior as absolutely similar to that of heroin and cocaine addicts. According to them, drug and food dependence is determined by the same mechanism of neuroadaptation .
In addition to gaining excess weight and an increased risk of cardiovascular problems due to obesity, unhealthy eating can be detrimental to the brain, researchers say.
They found that high-calorie foods can affect the action of dopamine in the brain, which can impair cognitive abilities.
Hormone levels, corticosterone , are also elevated, which increases the risk of depression, anxiety and other negative emotions and behaviors.
Corticosterone has a relatively insignificant function in the body compared to another stress hormone, cortisol.
With a sudden change in diet from high-calorie and fatty foods to healthier ones, it is possible to develop withdrawal symptoms and greater sensitivity to stressful situations , the research team explained.
The results of the study are published in the online edition of the International Journal of Obesity .
