chocolate such as alcohol or drugs. The body had to suffer withdrawal symptoms comparable with those caused by the waiving of wine or heroin. To establish a possible parallel study involved one of the Boston University School of Medicine in collaboration with the University of Rome La Sapienza.
American researchers, led by Italian Pietro Cottone and Valentina Sabino, have concluded that eating foods high in fat and sugar would have a significant effect on our brains, so as to cause changes similar to those resulting from dependence on alcohol or drugs. Published
in the journal PNAS, the study proposes an argument that once the body has become accustomed to certain tastes, can only suffer when the absence forced him to private. This is what happens frequently to those undergoing often very strict diet for short periods of time in order to lose weight, but then falls in the old errors and goes back with interest.
Scientists have studied the behavior of 155 mice, dividing them into two groups. The first group were offered foods high in fat chocolate-flavored, while the second was given normal food. Thus, the mice were able to verify that the first group, those "tainted" with chocolate, returned to normal diet showed signs of nervousness and refusing food, while among the other mice did not noticed any change.
undergo examinations, the brains of mice in the first group showed clear alteration in the levels of gene CRF (corticotropin-Realeasing Factor) in the amygdala, which is the area involved in the sensations related to food. The levels of gene indicted returned to normal only when the mice began again to eat the food in the flavor of chocolate.
Dr. Cotton noted that the flux levels of CRF gene has allowed us to understand "the causes of the recurring failures of the diets. This leads to the reasoning of doctors to find a similarity between the behavior of the mice experiment and that of those who continually try in vain to lose weight, and consequently established the principle of dependence, even with those who feel "forced" to drugs and alcohol.
According to Dr Valentina Sabino, in fact, "the activation of CRF during abstinence from food with a sweet tooth causes a negative emotional state, in charge of the signs of anxiety and contributes to relapse in the grip of food prohibited. The stress experienced by the 'strength' of the diets during abstinence from food tasty - ends - has similarities with the neurobiological negative emotional state of those who depend on alcohol and drugs.
