Summary

Primary objective of this study is to investigate the effect of sugar reduction (starting from glucose and sucrose, respectively) on postprandial glycemic response to apple juice by comparing the reference food item apple juice (control) with the test product (apple juice with low sugar content) in male humans with impaired fasting glucose (IFG) (5.6-6.9mmol/l resp. 100-125mg/dL) (Kerner and Brückel, 2012 (DDG recommendation)) Secondary objective of this study is to investigate the effect of sugar reduction on postprandial insulinemic response. Exploratory objectives are to investigate further characteristics of postprandial glucose and insulin response and insulin sensitivity, gastrointestinal side effects and safety aspects.

Detailed description

Objectives: Investigating the effect of sugar reduction in apple juice on glycemic and insulin response to ingestion of this drink. Subjects/Methods: In a double-blind randomized placebo-controlled clinical trial with cross-over design 30 male adults with impaired fasting glucose (IFG) received an oral drink of 500mL: 1. Verum: Apple juice, treated (low sugar content); 2. Control: Untreated apple juice (normal sugar content). Capillary blood glucose and venous plasma insulin were measured twice at baseline and then at times 0 (start of drink), 15, 30, 45, 60, 90 and 120 min.

Conditions

• Impaired Fasting Glucose

Interventions

Type	Name	Description
OTHER	treated apple juice with low sugar content	Each study participant consumed 500 mL test juice at the morning of the interventional day. The 500 mL bottle content had to be ingested within 5 minutes. an intravenous catheter was inserted into a forearm vein for blood withdrawal at baseline, directly before (time point 0) and 15, 30, 45, 60, 90 and 120 minutes after starting the ingestion of the test product. From all samples plasma insulin was measured. From the blood samples taken at baseline and 120 minutes after consumption of the test product safety parameters were determined. Capillary blood was taken from the finger pad using a HemoCue® Safety Lancet at baseline (twice) and once directly before (time point 0) and 15, 30, 45, 60, 90 and 120 minutes after ingestion of the test product.
OTHER	un-treated apple juice with normal sugar content	Each study participant consumed 500 mL test juice at the morning of the interventional day. The 500 mL bottle content had to be ingested within 5 minutes. an intravenous catheter was inserted into a forearm vein for blood withdrawal at baseline, directly before (time point 0) and 15, 30, 45, 60, 90 and 120 minutes after starting the ingestion of the test product. From all samples plasma insulin was measured. From the blood samples taken at baseline and 120 minutes after consumption of the test product safety parameters were determined.
