Resumo

Introduction: Several spices, including ginger (Ziniber officinale) and cinnamon (Cinnamomum zeylanicum), have been reported on for their supposed thermogenic effect. However, the literature is scarce in this regard.
Objective: To evaluate the effect of ginger and cinnamon teas on energy metabolism.
Methods: 10 women (26,8±6,2years; BMI: 21,5±1,4kg/m2) participated in this randomized and cross-over study. Three days of tests were performed. All participants consumed a standard breakfast, with 200mL of water or 200mL of ginger (2g) or cinnamon (2g) prepared under infusion. There was an interval of at least 7 days between evaluations. Resting-energy expenditure (GER) and diet-induced thermogenesis (TID) were measured by indirect calorimetry using the Quark RMR metabolic gas analyzer, for four moments (fasting, 40min, 2 and 4hours after tea intake). This research was approved in the COF of UFMG (CAAE 917 02918.2.0000.5149). The data were evaluated using the two way ANOVA test with repeated measures, using SPSS software (significance level p<0.05).
Results: Consumption of ginger tea or cinnamon tea did not change the TID compared to placebo (p=0.186). The most expressive values for the energy expenditure were observed within the first 40 minutes after the ingestion of the standard breakfast, being 1501,3±166,4kcal after ginger tea ingestion, 1452,7±176kcal after consumption of the cinnamon tea and 1461,6±186,3kcal after water consumption. As expected, there was an effect of time on energy expenditure (p<0.001). However, there was no effect of treatment or interaction time and treatment (p=0.502). Conclusion: The acute consumption of ginger tea or cinnamon tea did not alter the energy metabolism of the evaluated participants, thus, we can not consider them thermogenic food.
