Drink tea for your health 05:34 2004-10-27 Drinking tea appears to affect the brain in a similar way as drugs prescribed for Alzheimer's disease, UK researchers report. The team, based at Newcastle University's Medicinal Plant Research Center, investigated the properties of green and black tea, as well as coffee, in a series of laboratory experiments. The results showed that both types of tea inhibited the activity of enzymes associated with the development of Alzheimer's disease. Coffee, however, had no significant effect, according to a report in the current edition of Phytotherapy Research. The teas inhibited the activity of acetylcholinesterase -- the same mechanism of action used by drugs such as Novartis' Exelon and Pfizer's Aricept. The teas also hindered the activity of the butyrylcholinesterase, which has been found in senile plaques in the brains of Alzheimer's disease patients. Green tea obstructed the activity of beta-secretase, which also plays a role in the production of senile plaques, and is the focus of research by companies such as Ireland's Elan, publishes Reuters. According to Halifax Live, a nice cup of tea might just be what the doctor ordered to improve your memory and protect against Alzheimer's disease, according to new research. Researchers at Newcastle University in England, found both green tea and black tea inhibited the activity of enzymes associated with the development of Alzheimer's Disease, however, coffee drinkers take note, coffee had no significant effect. The researchers conducted a series of experiments to examine the properties of green and black tea as well as coffee. Although black tea is derived from the same plant as green tea, it did not provide the same amount of protection found in green tea. Both teas inhibited the activity of the enzyme acetylcholinesterase (AChE), which breaks down the chemical messenger or neurotransmitter, acetylcholine. Alzheimer's is characterised by a drop in acetylcholine. However, green tea also obstructed the activity of beta-secretase, which plays a role in the production of protein deposits in the brain which are associated with Alzheimer's disease. Green tea was also found to be longer lasting, compared to black tea. The researchers report green tea continued to have its inhibitive effect for a week, whereas black tea's enzyme-inhibiting properties lasted for only one day. The study's lead researcher, Doctor Ed Okello, says green tea was most effective but further tests are needed. It's hoped these findings could possibly lead to the development of a new treatment for Alzheimer's disease, an extreme and aggressive form of dementia affects an estimated ten million people worldwide. Drinking both teas stopped the enzyme 'acetylcholinesterase' from doing its job. 'acetylcholinesterase' is responsible for breaking down the chemical messenger or neurotransmitter, acetylcholine, reports WorldNow.
