Green Tea's Impact on Blood Viscosity in Healthy Adults

This study aims to explore how consuming green tea might affect the thickness and flow of blood, known as blood viscosity, in healthy individuals. It specifically targets non-smokers without a history of cardiovascular disease or metabolic disorders, who are also not taking any heart-related medications. This research is important because understanding how green tea impacts blood viscosity could offer insights into its potential benefits for heart health, potentially leading to new dietary recommendations for preventing cardiovascular issues. Participants in this study undergo a series of tests and follow specific dietary restrictions before their participation. Initially, participants are required to provide a blood sample and undergo various health checks. They then consume 200 mL of green tea, with blood samples taken before and at two intervals after consumption to assess changes in blood viscosity. A second visit involves repeating the procedure with hot water instead of green tea to serve as a control. The study also includes a questionnaire about dietary habits and hydration levels, with participants asked to maintain certain routines to ensure consistent results.
