PDF | Tea is an important dietary source of flavanols and flavonols. Most research has linked green or black tea or compounds in tea (such as catechins) to improved blood sugar control or reduced risk of type 2 diabetes. Gallic acid content ranged from 0.039 to 6.7 mg/g; the fermentation process also elevated remarkably gallic acid levels in black teas (mean level of 3.9 1.5 mg/g). Evaluation of beverages' pH values The measurement of the beverages’ pH values were made at 25°C through a pH electrode connected to an ion analyzer (DM-23, Digimed, São Paulo, SP, Brazil). Epidemiological/Clinical Studies on the Ability of Tea Catechins to Prevent Influenza Infection.

Around 80% of the total tea produced in India is consumed by the domestic population.

The ability of catechins or natural tea compounds to prevent an influenza infection has been documented since the late 1990s [32,33,34].Although experimental studies showed antiviral activity with tea consumption, evidence for its clinical efficacy is not conclusive. Tea Board, 14 B T M Sarani (Brabourne Road) Kolkata-700 001 Executive Summary of Study on Domestic Consumption of Tea in India India is the 2nd largest producer of tea in the world and accounts for the highest tea consumption globally. Due to heavy demand of black tea, most of the tea estates are concentrating their production on black tea only.
