Popis: Gastrointestinal tract is an important connector between food intake and body weight, it senses basic tastes in a similar manner as the tongue. The aim of the study was to find out how gut hormone glucagon-like peptide-1 (GLP-1) influences taste preference. Fourteen healthy participants (six male and eight female) were included in this double-blind, placebo-controlled crossover study. After overnight fast and salty fluid (oral sodium load), participants were randomized to receive placebo (500 mL of 0.9% saline) or GLP-1 infusion (1.5 pmol/kg/min) over a 3-hour period. At the end of infusion, participants chose food preferences from illustrations of food types representing 5 tastes. After 7 days, the protocol was repeated, this time those that had received placebo first got GLP-1 infusion, and those having received GLP-1 first got placebo. Change of taste preference after GLP-1 infusion but not after placebo was reported as response, and non-response was reported in case of taste persistence. A statistically significant difference in response type was found between genders, with women being more likely to change their taste preference after GLP-1 than men. The change of taste upon GLP-1 infusion observed in women might be ascribed to estrogen weight-lowering effects accomplished by receptor-mediated delivery.
Probavni sustav povezuje unos hrane i tjelesnu masu razlikujući osnovne okuse sličnim mehanizmima kao i jezik. Cilj ove studije bio je istražiti kako glukagonu sličan peptid-1 (GLP-1) utječe na sklonost određenom okusu. Četrnaestoro zdravih ispitanika (šest muškaraca i osam žena) uključeno je u randomiziranu, placebom kontroliranu ukriženu studiju. Ispitanicima koji su bili natašte dana je slana tekućina (oralno opterećenje solju), nakon čega su randomizirani za placebo (500 mL 0.9% fiziološke otopine) ili infuziju GLP-1 (1.5 pmol/kg/min) tijekom 3 sata. Na kraju infuzije ispitanicama su predočene slike hrane koje predstavljaju 5 osnovnih okusa pa su birali okus kojem su najviše skloni. Nakon 7 dana postupak se ponovio; onima kojima je prvi puta dan placebo primijenjen je GLP-1, a onima koji su prvi put dobili GLP-1 primijenjen je placebo. Promjena sklonosti određenom okusu nakon infuzije GLP-1, no ne i nakon placeba, smatrala se pozitivnim odgovorom, a negativan je bila nepromijenjena sklonost okusu. Analizirajući ispitanike prema spolu nađeno je da žene imaju veću vjerojatnost promjene sklonosti okusa nakon GLP-1 nego muškarci, što je bilo statistički značajno. Navedeno opažanje promjeni okusa nakon infuzije GLP-1 u ispitanica može se objasniti učinkom estrogena na gubitak tjelesne mase koji se objašnjava receptorski posredovnim prijenosom.
