Cuppa health cheer for UK's tea drinkers.

Byline: By Julie Cush

Drinking five cups of tea a day boosts the immune system and gives the body a better chance of fighting off infections, scientists have said.

An ingredient in the drink helps repel invading bacteria, viruses and fungi, according to a study in the Proceedings of the National Academy of Sciences.

A second experiment showed that immune system blood cells from tea drinkers responded five times faster to germs than the blood cells of coffee drinkers.

The studies used ethylamine, produced when the tea ingredient L-theanine is broken down in the liver.

Previous research suggests that ethylamine, found in black and green teas, may also target other pathogens, including parasites, viruses, and perhaps tumours.
