Tea is particularly rich in polyphenols, including catechins, theaflavins and thearubigins, which are thought to contribute to the health benefits of tea. Tea polyphenols act as antioxidants in vitro by scavenging reactive oxygen and nitrogen species and chelating redox-active transition metal ions. They may also function indirectly as antioxidants through 1) inhibition of the redox-sensitive t...

When a hot aqueous extract of black tea cools down, a colloidal complex (tea cream) is formed, which poses technological problems in industrial processes e.g. manufacture of instant tea and tea cordials. Removal of 'tea cream' by centrifugation leaves the residual liquor stripped to a great extent of the desirable characteristics of tea. The studies on the nature of tea cream, the mechanics of ...
Effects of tea catechins (tannins) on lipid metabolism were studied in male weanling rats fed a 25% casein diet containing 15% lard and 1% cholesterol for 28 days. Crude tea catechins prepared from green tea powder were supplemented at a 1% and 2% of the lard-cholesterol diet. The addition of 2% tea catechins slightly depressed growth but at the 1% level was without effect. Tea catechins decrea...
Objectives: This study aims to evaluate the possible relationship between oral consumption of hot black tea and methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in a mid-sized town population in central Anatolia. Patients and Methods: Nasal swabs were taken from a total of 109 subjects (53 females, 56 males; mean age 34.4 years; range 18 to 65 years) including 55 non-tea drinke...
