The Effect of Honey-sweetened Coffee, Black Tea and Green Tea on Some Physiological Parameters

Summary

The goal of this clinical trial is to investigate whether a three-day consumption of honey-sweetened black tea, green tea, and coffee will have an effect on blood pressure, heart rate, and blood glucose. The main questions it aims to answer are:

Does honey-sweetened black tea, green tea, and coffee, respectively, have the ability to influence blood pressure, heart rate, or blood glucose level?

Research will compare honey-sweetened black tea, green tea, and coffee to a placebo (warm water) to see if honey-sweetened black tea, green tea, and coffee work to reduce or increase blood pressure, heart rate, or blood glucose.

Participants will:

Take honey-sweetened black tea, green tea, and coffee, OR plain black tea, green tea, and coffee, OR warm water, one cup a day for 3 days The beverages will be taken at the Physiology laboratory, University of Uyo, and the participants will be observed for 60 minutes, during which their blood pressure, heart rate, and blood glucose level will be measured. This procedure will be repeated for the 3 days of study.
