With the aging global population, Alzheimer’s disease and other types of dementia are set to become the new global pandemic. According to recent estimations, today about 55 million people have some form of dementia, and 78 million are projected to suffer from it by 2030.
However, science is working at full speed to find ways to sabotage this scary trend.
In a recent study, scientists have identified a cheap, simple way to prevent cognitive decline in older individuals—drinking tea!
In fact, the results from a study published in the journal Aging show that people who regularly drink black, green tea, or oolong tea reduce their risk of cognitive decline in old age by 50%. The results were even higher for those genetically predisposed to dementia—a whopping 86%.
Moreover, the study revealed that individuals who had drunk tea at least four times per week for about 25 years had more organized and efficient, more interconnected brains than those who hadn’t.
So will your kettle be the main thing you need to escape the grips of Alzheimer’s and cognitive impairment at an older age?—Not quite. Daily exercise, healthy meals, and sleep also play a crucial role in preventing cognitive decline.
Another study found a connection between the habit of tea drinking and improved verbal fluency in the oldest population of China (aged 80 or over). The results indicate that the more tea the elderly consumed, the better their verbal fluency scores were.
The same “brain-preserving effects” were attributed to drinking coffee. That said, recent scientific evidence also suggests that going overboard with coffee drinking may harm your brain health. So, you may be better off swapping that unteenth cup of coffee for a cup of tea.
