ObjectivesWe aimed to evaluate the acute effect of a fructose-rich single meal on metabolic and inflammatory biomarkers RESEARCH METHODS AND PROCEDURES: This single-center, double-masked, randomized crossover trial recruited females aged 20 to 47 with a normal body mass index and was conducted at Hospital das Clínicas (Belo Horizonte, MG, Brazil). Participants received a standardized meal with either sucrose, glucose, or a fructose overload. Blood samples were collected after overnight fasting (baseline) and at 30, 60, 120, and 240 minutes postprandial. Serum levels of glucose, triglycerides (primary outcome), total cholesterol, alanine aminotransferase, aspartate aminotransferase, adiponectin, leptin, resistin, interleukin (IL)-2, IL-4, IL-5, IL-6, IL-10, IL-17, interferon-gamma, tumor necrosis factor, eotaxin, and total blood leukocytes were measured.ResultsThis trial was completed with 25 enrolled participants, and three dropped out. The per-protocol analysis included 22 participants. As expected, postprandial glycemia increased 30 minutes after consuming meals rich in sucrose (P = 0.045) or glucose (P < 0.001). Triglyceride and leucocyte concentrations increased only at 240 minutes after consuming a high-fructose meal (P < 0.05). Regardless of the type of carbohydrate overload, leptin concentrations decreased postprandially compared to baseline at all time points (P < 0.05). Four participants reported adverse events after consuming the standardized meal with glucose or fructose, including nausea and malaise.ConclusionsOur findings indicate that a fructose-rich single meal leads to a more significant increase in triglyceride and leukocyte concentrations compared to glucose and sucrose in healthy women. These findings support concerns regarding the potential inflammatory and metabolic dysfunction associated with frequent consumption of high-fructose meals.Copyright © 2024.
