Brief Summary

The type 2 diabetes mellitus is a chronic disease and it is a highly prevalent globally. Cinnamon is a spicy used on the traditional cuisine, which have as been associated with beneficial effects on postprandial blood glucose levels (BGL). The aim of the present study was to investigate the effect of cinnamon tea (6g C. burmannii/100mL) on postprandial glycaemia in type 2 diabetic adults. Following ethical committee approval, thirty-six subjects were selected and randomly allocated in 2 groups (n=18): cinnamon group, which was administrated OGTT (oral glucose tolerance test) followed by cinnamon tea; control group, which was administrated only OGTT. At baseline, anthropometric data, medical condition and pharmacological therapy were collected. A 24-hour dietary recall was taken preceding each intervention. Food Processor SQL (version 10.5.9) program was used to analyze the food nutritional composition. Chemical analysis was performed for total phenols determinations (adapted from Prabha et al) and antioxidant activity for FRAP and for DPPH tests (adapted from K. Thaipong et al.) Statistical analysis was performed using SPSS Statistics program. Data are mean±SEM.

Outcome Measures

Primary Outcomes (7)

  • Blood glucose levels at beginning

    Mean values of blood glucose levels from both control and experimental groups

    At beginning (before intervention)

  • Blood glucose levels at 30 minutes

    Mean values of blood glucose levels from both control and experimental groups

    At 30 minutes after intervention

  • Blood glucose levels at 60 minutes

    Mean values of blood glucose levels from both control and experimental groups

    At 60 minutes after intervention

  • Blood glucose levels at 90 minutes

    Mean values of blood glucose levels from both control and experimental groups

    At 90 minutes after intervention

  • Blood glucose levels at 120 minutes

    Mean values of blood glucose levels from both control and experimental groups

    At 120 minutes after intervention

  • Incremental area under the curve of blood glucose

    Based on the blood glucose values, the blood glucose incremental area under the curve (AUCi) of each participant was defined using the GraphPad Prism program (version 5.0)

    At 120 minutes after intervention

  • Variation of blood glucose maximum concentration

    Mean values of glucose maximum concentration variation

    At 60 minutes after intervention

Secondary Outcomes (13)

  • Anthropometric parameters - body weight

    At baseline

  • Anthropometric parameters - height

    At baseline

  • Anthropometric parameters - waist circumference

    At baseline

  • Anthropometric parameters - body mass index

    At baseline

  • Anthropometric parameters - Skeletal muscle mass

    At baseline

  • +8 more secondary outcomes

Study Arms (2)

Placebo (OGTT)

PLACEBO COMPARATOR

The control group was given an glucose solution to oral glucose tolerance test (OGTT) .

Other: Placebo (OGTT)

Cinnamon (OGTT plus aqueous cinnamon extract)

EXPERIMENTAL

The Experimental group was given an glucose solution to oral glucose tolerance test (OGTT) followed by aqueous cinnamon extract.

Other: Cinnamon (OGTT plus aqueous cinnamon extract)

Interventions

The control group was given an glucose solution to oral glucose tolerance test (OGTT) The glucose solution consist in a glucose drink with 75g of anhydrous D-Glucose dissolved in 200 mL of water at room temperature, as prescribed by ADA. The blood glucose levels were measured before intervention at fasting (t0) and after 30 (t30), 60 (t60, 90 (t90) and 120 (t120) minutes after intervention from both groups.

Placebo (OGTT)

The intervention group was given an glucose solution to OGTT followed by a cinnamon aqueous extract. The glucose solution consist in a glucose drink with 75g of anhydrous D-Glucose dissolved in 200 mL of water at room temperature, as prescribed by ADA. The blood glucose levels were measured before intervention at fasting (t0) and after 30 (t30), 60 (t60, 90 (t90) and 120 (t120) minutes after intervention from both groups.
