Do you remember the proverb: “An apple a day keeps the doctor away”? Today we could say: “A cup of tea a day keeps dementia away”. Or may be it is better to say “Drinking tea every day keeps dementia away”. This is especially important for those who are genetically predisposed to Alzheimer’s disease. And it does not mater what kind tea, it is not limited by a particular type of tea. It could be green, black, white, or oolong tea, states in his study Assistant Professor Feng Lei from National University of Singapore.
In this study, that involved 957 Chinese 55+ seniors, has been found that regular consumption of tea decreases the risk of cognitive decline by 50 %.In addition, ongoing tea consumption by carriers of the APOE e4 gene who are genetically at high risk of developing Alzheimer’s disease, could reduce a cognitive impairment risk by 86 %.The research team also discovered that while the neuroprotective role of tea consumption on cognitive function was conducted on Chinese elderly, the results could be applied to other races as well.These findings could have important implications in area of dementia prevention, because effective pharmacological therapy for neurocognitive disorders are far from satisfactory, despite a lot of high quality drug trials.Tea is one of the most widely consumed beverages in the world. Above data suggests that a simple and inexpensive routine, such as daily tea drinking, can reduce one’s risk of developing neurocognitive disorders later in his/her life.Based on current knowledge, this long-term benefit of tea consumption is due to the bioactive compounds in tea leaves, such as catechins, theaflavins, L-theanine and others.These compounds exhibit anti-inflammatory and antioxidant potential and other bioactive properties that might protect the brain from vascular damage and neurodegeneration.
I think, it’s time to make a cup of tea! Which one do you prefer – black, green, white, or oolong?
