Green Tea Catechins Against COVID-19: Lower COVID-19 Morbidity and Mortality in Countries with Higher per capita Green Tea Consumption

Background: Several vaccines are currently validated for COVID-19 prevention and mass vaccination has already been started in many countries. Nevertheless, it is likely that the development of an efficient therapy reduces severity/mortality would be still important a rather prolonged time, particular, due to new variants SARS-CoV-2. lines emerging evidence suggest green tea catechins such as epigallocatechin-3-gallate have direct anti-viral activity affect factors associated with severity. Objective: Considering major constituents tea, may expected countries higher per capita consumption less affected by COVID-19. This study assessed this possibility. Methods: Among population at least 3 million (n=134), those relatively high (above 150 g) identified (n=21); (ii) normalized values cases (morbidity) deaths (mortality) groups low were compared. Results: Striking differences morbidity mortality between ‘high’ ‘low’ found. The observed after adjustment onset disease. An analysis using multiple linear regression approach suggests associations present level individual Conclusions: Results study, taken together pharmacological evidence, can give valuable clues treatment/amelioration
