The impact of carbohydrate intake on the behavior and cognitive functions of children and adolescents


Introduction. Although carbohydrates are the most commonly studied nutrients regarding their influence on cognitive functions, there is no unequivocal agreement on whether this influence really exists and what its manifestations are.

Aim. This study is a literature review of research on the association between sugar intake, behavior and cognitive functions in children population.

Material and methods. The analysis of the studies on the carbohydrate intake and its impact on behavior and cognitive functions of children and adolescents on the basis of MEDLINE database was conducted. The studies were found in PubMed Internet search engine. The following words were implemented in various combinations: “sugar”, “carbohydrate”, “glycemic index”, “GI”, “glucose” as well as “cognition”, “cognitive”, “learning”, “memory”, “attention”, “behavior”, “hyperactivity”. The number of 27 publications was chosen and the information they contained was analyzed.

Results. Despite multiple studies on the impact of carbohydrate intake and their glycemic index on cognitive functions, there is still no agreement on this issue. Multiple studies indicate the association between glycemic index and cognitive processes. The positive impact of low GI breakfast intake on the concentration and memory is relatively frequently emphasized. The concept that indicates the association between sugar intake and hyperactive behavior among children also has not been unequivocally confirmed in the analyzed studies – contrarily – some of them indicated lack of such relationship. The placebo effect may be the explanation for the above concept. The association between the number of carbohydrates in diet and sleep disorders also has not been proved.

Conclusions. Although there are no unequivocal scientific foundations to limit the intake of simple sugars and consume polysaccharides with low GI to improve behavior and cognitive functions, such actions are consistent with a healthy diet and should be recommended for children and adolescents.

The cult of the body and its psychological consequences among adolescent girls


Taking into consideration the problem of “the cult of the body” among young women, the sociocultural context of their upbringing should be analyzed. Nowadays, it can be observed that many young women actively participate in promoting “the cult of the body”. The aim of the aforementioned actions is to get a slim, attractive figure consistent with the trends of women’s attractiveness promoted in the media. The analysis of the social networking sites and blogs indicates that more and more often women themselves are encouraged to promote their attractive, thin image in the Internet. This article will attempt to characterize the phenomenon of “the cult of the body”, in which adolescent women are engaged and which shapes their image of the body and has a potential influence on psychological and physical aspects of their existence. The analysis of the results of the research takes into account the analyzed subject and developmental conditioning of the time of adolescence in the context of sociocultural changes.
