Health Tips: Tea-drinking & our immune system



DID YOU KNOW that tea does miracles in enhancing the immune system in the body required to fight against deadly viruses?

Research conducted by Dr. Jack F. Bukowski, a professor at Brigham and Women's Hospital in Boston and Harvard Medical School, has identified L-theanine, an amino acid present only in tea, as being broken down in the liver to ethylamine, a molecule that primes the response of an immune system element called the gamma-delta T cell. Gamma-delta T cells in the blood are the first line of defence against many types of bacteria, viral, fungal and parasitic infections. 

The T cells prompt the secretion of interferon, a key part of the body's chemical defence against infection. "We know from mouse studies that if you boost this part of the immune system it can protect against infection”, Bukowski said. 

Testing of blood samples from volunteers further proved that the immune system blood cells from tea drinkers responded five times faster to germs than did the blood cells of coffee drinkers.
