Drink Tea to Fight Heart Disease

It may be too much for some even to think of drinking eight cups of tea a day but health experts say the intake can help fight heart disease, improve brain power and also boost longevity.

Independent dietician Dr Carrie Ruxton’s research on caffeine at King”s College, London, saw her review 47 published studies to reach the conclusion that caffeinated drinks such as tea, coffee and cocoa have positive effects on mental function, increasing alertness, feelings of well-being and short-term memory.

It was already linked the drink’s healthy antioxidant properties and high flavonoid content to preventing heart disease and cutting the risk of some cancers by precious studies.

Dr Ruxton has supported earlier reports by claiming that an optimal intake of 400mg of caffeine a day leads to “key benefits in terms of mental function and heart health.” She assessed three studies, accounting for almost 90,000 patients, to find that drinking four cups of tea or coffee a day reduced chances of cardiovascular disease.

She also referred to another study of 26,500 middle-aged smokers, which hinted that men who ingested more than two cups of tea a day pulled down the probability of getting a stroke by 20 per cent.

Dr Ruxton insisted that she aimed to “debunk” false beliefs surrounding caffeine. Moreover, she asserted that people who avoid drinking team might be doing more harm than good. “People who cut out caffeinated drinks may miss out on the potential health benefits of the compounds they contain,” the ‘Daily Express’ quoted her as saying.

She further suggested that there is no need for parents to stop children from drinking tea and coffee. In fact, she claimed it was better than juice in some regards.

Also, Dr Catherine Hood, of the Tea Advisory Panel, agreed to Dr Ruxton’s claims. She said: “Caffeinated drinks have been unfairly demonised. Black tea, in particular, contains polyphenols, which are natural plant antioxidants. These have beneficial effects on many biochemical processes in the body because they protect cells against harmful free radicals.”

“Flavonoids are thought to be especially useful, with a number of studies reporting a link between them and lower risk of heart attack,” she further added.

For 4,000 years, the Chinese people have been using green tea as treatment for everything from headaches to depression.

Today, studies are conducted in Asia and the west in order to produce hard evidence of the health benefits of green tea. In the 1994 edition of the Journal of National Cancer Institute, the results of an epidemiological study stated that one of the health benefits of drinking green tea is that it can reduce the risk of esophageal cancer in Chinese men and women by up to 60%.

The rich presence of catechin polyphenols, particularly epigallocatechin gallate (EGCG) is the reason why green tea has so much health benefits. A powerful antioxidant, EGCG can not only inhibit the growth of cancer cells but can also destroy them without harming healthy cells.

The University of Purdue has also concluded a research on how a certain compound present in green tea can stop cancer cells from growing. Still another health benefit of green tea is its ability to lower down cholesterol levels and improve the ratio between good (HDL) cholesterol and bad (LDL) cholesterol.
