# Moderate sugar-sweetened beverage consumption impairs low density lipoprotein metabolism in healthy young men: a randomized, controlled, double-blinded study

Liechti, Marc. Moderate sugar-sweetened beverage consumption impairs low density lipoprotein metabolism in healthy young men: a randomized, controlled, double-blinded study. 2017, University of Zurich, Faculty of Medicine.

## Abstract

Background: Sugar-sweetened beverage consumption in high quantities impairs lipid metabo-lism and therefore causes metabolic disorders in obese subjects. However, the effect of sugar sweetened beverages in lower doses on normal weight healthy subjects remains less clear.
Objective: The aim of the study was to investigate the impact of sugar-sweetened beverage consumption over 7 weeks on low density lipoprotein particle size and distribution.
Design: 96 normal weight, healthy young male subjects were included in a randomized, double blind, monocentric, controlled nutritional trial and were randomly assigned to 4 intervention groups. Over a period of 7 weeks, subjects were instructed to consume on a daily basis 600ml of sugar-sweetened beverages containing either 80g fructose, 80g glucose or 80g sucrose, whereas a control group was advised to abstain completely from sugar-sweetened beverages.
Results: Small low density lipoprotein particles (22-25.6nm diameter) increased and large low density lipoprotein particles (25.6-28.5nm diameter) decreased after sugar-sweetened beverage consumption compared with baseline (p = 0.04). The sucrose containing intervention decreased the largest low density lipoprotein particles (27.2-28.5nm diameter) significantly (p = 0.039).
Conclusion: This study shows that even moderate consumption of sugar-sweetened beverag-es leads to adverse effects on low density lipoprotein metabolism in normal weight, healthy young men.
