Acute Inflammatory and Metabolic Effect of High Fructose Intake in Normal Weight Women: Double Blind, Randomized Crossover Study
Abstract
Fructose consumption is associated with the development of metabolic diseases and low-grade inflammation. However, the acute effect of a single meal rich in fructose on the metabolic and inflammatory response is not fully understood. This study will to evaluate the acute metabolic and inflammatory effect caused by a meal containing fructose overload. This will be a three-arm crossover, randomized, double-blind clinical trial.
Participants will undergo the three interventions for random order: (i) standardized meal plus sucrose overload; (ii) standardized meal plus glucose overload; (iii) standardized meal plus fructose overload. During the washout period (7 to 21 days), the subjects will instructed to maintain their usual eating behavior and physical activity.
On the day of each intervention, participants will to the outpatient clinic in the morning after an overnight fast. Anthropometric data (weight, height, and waist circumference) will collected. Body composition will evaluated using bioimpedance (Quantum® apparatus, RJM Systems, Michigan) and blood pressure and heart rate (digital monitor, model HEM705CP®, Omron) will measured after 30 minutes of rest.
A catheter with a three-way stopcock will inserted into the arm of the volunteers. Blood samples (5mL) will collected after overnight fasting (baseline) and 30, 60, 120, and 240 minutes after the standardized meal containing sucrose or glucose or fructose overload. Participants will remain seated throughout the evaluation…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 22 participants or records.
