Is Coffee a Proper Noun, and What Does Daily Ceylon Tea Do
Coffee is a common noun, not a proper noun, unless it forms part of a brand or place name such as a specific estate. The same rule applies to tea: Ceylon black tea names an origin, while Darjeeling is protected by the Tea Board of India. Daily consumption of true tea has been linked to slower cognitive decline in older adults.
A National University of Singapore study followed 957 Chinese adults over 55 and found daily tea drinkers had about a 50 percent lower risk of cognitive decline, rising to 86 percent among carriers of the apolipoprotein E4 gene. Researchers credit catechins, theaflavins, thearubigins, and theanine for anti-inflammatory and antioxidant effects, and note the benefit applies to green, black, and oolong tea alike.
Ceylon black tea, as a world-renowned tea, has drawn much attention for its place of origin and health benefits. A longitudinal study by the National University of Singapore followed 957 Chinese seniors over the age of 55 and found that daily tea drinking can reduce the risk of cognitive decline by up to 50%, with an even more pronounced effect in those carrying the genetic susceptibility to Alzheimer's disease, lowering the risk by as much as 86%. The study points out that bioactive compounds in tea, such as catechins, theaflavins, thearubigins, and theanine, have anti-inflammatory and antioxidant potential and can protect the brain from vascular damage and neurodegeneration. This article focuses on the origin of Ceylon black tea, the benefits and side effects of long-term consumption, and retains relevant recommendations for the Front Street brand, providing professional reference for coffee and tea enthusiasts.
Drinking a cup of tea every day may help people stay away from dementia. This conclusion comes from a recent study led by Feng Lei, Assistant Professor in the Department of Psychological Medicine at the Yong Loo Lin School of Medicine, National University of Singapore.
The longitudinal study included 957 Chinese graduates over the age of 55, and the results showed that daily tea drinkers had a 50% lower risk of cognitive decline. For those carrying the apolipoprotein E4 gene—that is, those with a genetic susceptibility to Alzheimer's disease—the risk of cognitive impairment could be reduced by as much as 86%.
The research team also found that tea's neuroprotective effect on cognitive function is not limited to a specific type of tea; as long as it is brewed from tea leaves, such as green tea, black tea, or oolong tea, similar effects may occur.
Although the study subjects were older Chinese adults, the researchers believe the results also apply to other ethnic groups. Associate Professor Feng explained: "Our findings have important implications for dementia prevention. Despite ongoing high-quality drug trials, effective drug treatment for neurocognitive disorders such as dementia remains difficult to achieve, and existing prevention strategies are far from satisfactory. Tea is one of the most widely consumed beverages in the world. Our data show that a simple and inexpensive lifestyle habit like drinking tea every day can reduce the risk of neurocognitive disorders in later life."
He added: "Based on current knowledge, the long-term benefits of tea drinking come from bioactive compounds in tea leaves, such as catechins, theaflavins, thearubigins, and theanine. These compounds exhibit anti-inflammatory, antioxidant, and other bioactive properties and may protect the brain from vascular damage and neurodegeneration. However, our understanding of the detailed biological mechanisms remains very limited, and more research is needed to find clear answers."
In this study, the team collected tea-drinking data from community-dwelling older adults between 2003 and 2005. Before 2010, the cognitive function of these older adults was assessed every two years using standardized tools, while information on lifestyle, medical conditions, physical and social activities was also collected. These potential confounding factors were carefully controlled in the statistical models to ensure the robustness and validity of the findings.
Assistant Professor Feng and his team are planning further research to gain a deeper understanding of the impact of Asian diets on the cognitive health of older adults. They also hope to investigate the role of bioactive compounds in tea and conduct more rigorous verification through methods such as evaluating biomarkers and carrying out randomized controlled trials. Randomized controlled trials randomly assign participants to an experimental group or a control group to eliminate biased results.
According to the United Nations, in 2017 the global population aged 60 and over was about 962 million, accounting for 13% of the world population. In addition, the population aged 60 or above is growing at about 3% per year. It is expected that the global older population will reach 1.4 billion in 2030, 2.1 billion in 2050, and 3.1 billion in 2100. The global population is aging rapidly, which will indeed drive up the incidence of dementia, and tea may significantly reduce the risk of dementia in older adults.
For coffee lovers who want to try tea, Front Street recommends paying attention to tea quality and brewing methods, ensuring the tea leaves are intact and additive-free in order to obtain more bioactive compounds. Front Street also recommends appropriately adding Ceylon black tea to daily drinks to balance flavor and health.
