WSTĘP: Produkty typu light, lekki oraz fit pojawiają się coraz częściej na polskim rynku, a producenci żywności, chociaż mają obowiązek umieszczania na etykietach produktów informacji o obniżonej wartości energetycznej i odpowiednich oznaczeń, nie zawsze robią to prawidłowo. Brak ścisłych regulacji prawnych w zakresie nazewnictwa produktów niskoenergetycznych daje producentom żywności możliwość wprowadzania na rynek produktów, których nazwa może wprowadzić konsumentów w błąd w zakresie ich wartości odżywczych i zdrowotnych. Celem niniejszej pracy jest ocena spożycia wyrobów typu light, lekki oraz fit wśród studentów kierunku dietetyka. MATERIAŁ I METODY: Wykorzystując autorski kwestionariusz ankiety, przeprowadzono anonimowe badanie, w którym wzięło udział 117 studentów dietetyki. Wyniki opracowano za pomocą arkusza kalkulacyjnego Excel. WYNIKI: Z przeprowadzonej analizy wynika, że osoby z prawidłową masą ciała najczęściej spożywają produkty typu light kilka razy w miesiącu (34,9%), z nadmierną masą ciała 2–3 razy w tygodniu (41,2%), a z niedowagą rzadziej niż raz w miesiącu (28,6%). WNIOSKI: Niezależnie od stopnia studiów oraz miejsca zamieszkania studenci dietetyki najczęściej spożywają produkty light, „lekki” oraz fit kilka razy w miesiącu. Osoby o prawidłowej masie ciała, a także osoby, które zwracają uwagę i kontrolują masę ciała, spożywają te produkty kilka razy w miesiącu.

INTRODUCTION: Light, “lekki” and fit products appear increasingly more often on the Polish market, and food producers, although they are obliged to include information on the labels of products with a reduced energy value and appropriate markings, do not always do it correctly. The lack of strict legal regulations on the naming of low-energy products gives food producers the opportunity to market products whose name may mislead consumers in terms of their nutritional and health values. The aim of this study is to assess the consumption of light, “lekki” and fit products among students of dietetics. MATERIAL AND METHODS: An anonymous survey was conducted using an original questionnaire, in which 117 students of dietetics took part. The results were compiled using an Excel spreadsheet. RESULTS: From the analysis of the results, people with normal body weight most often consume light products several times a month (34.9%), with excessive body weight 2–3 times a week (41.2%), and those underweight less than once a month (28.6%). CONCLUSIONS: Regardless of their degree and place of residence, students of dietetics most often consume light, “lekki” and fit products several times a month. People with a normal body weight, as well as those who pay attention and control their body weight, consume these products several times a month.

Chronic-degenerative diseases (CDD) recognise a variety of exogenous and endogenous risk factors interacting with the organism for many years before disease onset. We applied genomic and postgenomic molecular analyses in experimental models characterised by different contribution of exogenous and endogenous CDD risk factors. Exposure of mice to halogen light for 28 days resulted in induction of cyclobutane dimers and oxidative DNA damage in the skin. Evaluation of postgenomic alterations by cDNA arrays revealed upregulation of DNA repair pathways, increased cell division rate and protooncogenes transcription, resulting in skin tumors, 1 year later. Exposure of p53-/+ mutant mice to cigarette smoke (CS) for 28 days induced DNA adducts formation in the lung. Postgenomic alterations included decreased apoptosis and increased cell division, as compared to CS-exposed wild type mice. These phenomena resulted in lung tumors, 9 months later. Transplacental exposure of mouse foetuses to cigarette smoke induced DNA adduct formation in the liver. cDNA arrays analyses demonstrated decreased cell division, apoptosis increase, and tissue hypoxia. These phenomena resulted in growth retardation of the whole organism. Molecular alterations were investigated in human trabecular meshwork, the non-replicating ocular epithelia involved in the pathogenesis of chronic degenerative glaucoma. Results indicate increased oxidative DNA damage in glaucoma patients as compared to unaffected controls. These four experimental studies suggest that DNA damage may result in different CDD (cancer, growth retardation, glaucoma) depending on the replication rate of the target cell population.
