How Tea Could Help Ward Off Parkinson’s Disease

2 Comments

Researchers from Singapore have revealed that drinking at least 23 cups of black tea a month, or about three-quarters of a cup a day, may lower your risk of developing Parkinson’s disease by a whopping 71 per cent.

Parkinson’s disease is a degenerative condition affecting movement and balance.

The benefits of the beverage did not appear to be linked to its caffeine content, suggest the results of the study of 63,257 Chinese men and women.

Green tea contains between 30 and 40 per cent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 per cent. Oolong tea is semi-fermented tea and is somewhere between green and black tea.

The four primary polyphenols found in fresh tea leaves are epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), and epicatechin (EC).

Despite results from previous studies reporting that green tea may reduce the risk of Parkinson’s, the new study, reported no benefits among participants of the Singapore Chinese Health Study.

Lead researcher Louis Tan from Singapore’s National Neuroscience Institute states that data was collected through in-person interviews using structured questionnaires.

Over the course of the study, 57 cases of Parkinson’s disease were documented, and while caffeine was associated with a protective effect, reducing disease risk by 45 per cent, the benefits of black tea were not affected by caffeine content, according to the researchers.

They said: ‘Black tea, a caffeine-containing beverage, showed an inverse association with Parkinson’s disease risk that was not confounded by total caffeine intake or tobacco smoking. Ingredients of black tea other than caffeine appear to be responsible for the beverage’s inverse association with Parkinson’s disease.’

Parkinson’s disease: Over to the Tea Advisory Panel

Commenting on the study, Dr Ann Walker, a member of The Tea Advisory Panel (TAP) said that the latest research study was great news for all UK ‘black tea’ drinkers.

‘In the past there seems to have been more of a focus by scientists reviewing the health benefits of green tea,’ she said.

She added that previous studies looking at tea drinking and Parkinson’s disease risk did not differentiate between black tea and green tea, while the protective effect of tea was attributed to the caffeine content.

‘In the current study, however, the beneficial effect of black tea did not appear to be influenced by caffeine intake, indicating that ingredients other than caffeine are responsible for black tea’s protective effects,’ said Dr. Walker.

‘A key difference between black tea and green tea lies in the types and amounts of flavonoids. Green teas contain more of the simple flavonoids called catechins. But when black tea is made, the catechins undergo oxidation resulting in the generation of more complex varieties, called thearubigins and theaflavins.’

‘The underlying mechanisms for this protective effect of black tea on Parkinson’s disease remains unclear until further research is done. But drinking even one cup of black tea per day could help to reduce the risk of Parkinson’s disease,’ she concluded.
