MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Individual beverages have been previously shown to influence risk of a wide range of cardiometabolic diseases. Less is known about beverage consumption and kidney disease risk.

In this study population, we found that one such beverage pattern consisted of soda, sugar-sweetened beverages, and water, and that higher adherence to the sugar-sweetened beverage pattern was associated with greater odds of developing incident kidney disease, even after accounting for demographic characteristics and established risk factors.  Continue reading

Short Term Sugar Sweetened Drinks May Not Be Detrimental To Adolescent Health

Abstract: Background: Adolescents consume more sugar-sweetened beverages than do individuals in any other age group, but it is unknown how the type of sugar-sweetened beverage affects metabolic health in this population.

Objective: The objective was to compare the metabolic health effects of short-term (2-wk) consumption of high-fructose (HF) and high-glucose (HG)–sweetened beverages in adolescents (15–20 y of age).

Design: In a counterbalanced, single-blind fashion, 40 male and female adolescents completed two 2-wk trials that included 1) an HF trial in which they consumed 710 mL of a sugar-sweetened beverage/d (equivalent to 50 g fructose/d and 15 g glucose/d) for 2 wk and 2) an HG trial in which they consumed 710 mL of a sugar-sweetened beverage/d (equivalent to 50 g glucose/d and 15 g fructose/ d) for 2 wk in addition to their normal ad libitum diet. In addition, the participants maintained similar physical activity levels during each trial. The day after each trial, insulin sensitivity and resistance [assessed via Quantitative Insulin Sensitivity Check Index (QUICKI) and homeostatic model assessment of insulin resistance (HOMA-IR) index] and fasting and postprandial glucose, lactate, lipid, cholesterol, insulin, C-peptide, insulin secretion, and clearance responses to HF or HG mixed meals were assessed.

Results: Body weight, QUICKI (whole-body insulin sensitivity), HOMA-IR (hepatic insulin resistance), and fasting lipids, cholesterol, glucose, lactate, and insulin secretion or clearance were not different between trials. Fasting HDL- and HDL3-cholesterol concentrations were w10–31% greater (P , 0.05) in female adolescents than in male adolescents. Postprandial triacylglycerol, HDL-cholesterol, HDL3-cholesterol, and glucose concentrations were not different between HF and HG trials. The lactate incremental area under the curve was w3.7-fold greater during the HF trial (P , 0.05), whereas insulin secretion was 19% greater during the HG trial (P , 0.05).

Conclusions: Moderate amounts of HF- or HG-sweetened beverages for 2 wk did not have differential effects on fasting or postprandial cholesterol, triacylglycerol, glucose, or hepatic insulin clearance in weight-stable, physically active adolescents.

MedicalResearch.com:  What are the main findings of the study?

Dr. Park: Nearly 1 out of 3 U.S. adults (30.5%) consumed sugar-sweetened beverages at least 1 time per day; 20% consumed sugar-sweetened beverages at least 2 times per day. About 8 out of 10 adults agreed that drinking sugar-sweetened beverages can contribute to weight gain. However, 8 of 10 adults also did not know the actual calorie content of a 24-oz fountain soda. After controlling for sociodemographic factors, adults who were neutral (neither agreed nor disagreed) that drinking sugar-sweetened beverages can contribute to weight gain were more than 1-and-a-half times more likely to consume sugar-sweetened beverages at least 2 times per day. Conversely, knowledge about the calorie content of a 24-oz fountain soda was not associated with sugar-sweetened beverage intake.
