Tea is one of the most popular beverages in the world. In 2016, Americans consumed more than 3.8 billion gallons [1] of tea, with black tea being a favorite. This is good news – due to the numerous possible health benefits of tea consumption, which have been well researched.

Recent data from a Singaporean human trial has reaffirmed the role of tea drinking in reducing the risk of cognitive decline in older persons.

Led by Feng Lei, an assistant professor at the National University of Singapore’s Yong Loo Lin School of Medicine, the study focused on 957 Chinese seniors aged 55 years or older. Lei and his team discovered that the neuroprotective role of daily consumption of tea is not a bailiwick of one tea variety and is not limited to one race. They published the research outcomes [2] in The Journal of Nutrition, Health, & Aging.

The research team noted that drinking “real tea” – tea that is brewed from the leaves of Camellia sinensis, such as green, black (Earl Grey, English Breakfast, Assam, etc) or oolong, reduces a person’s risk of developing neurocognitive disorders later in life. The authors gathered information on the participants’ tea drinking habits, lifestyles, medical conditions, and physical and social activities. They attributed the neuroprotective effect of brewed tea to a combination of bioactive compounds which have anti-inflammatory and antioxidant properties that protect the brain from vascular damage and neurodegeneration.

The neuroprotective cognitive effects of tea have been widely explored by scientists: A study that first appeared in The American Journal of Clinical Nutrition [3] confirmed the association between regular tea consumption and lower risks of cognitive impairment and decline. A Japanese study [4] determined the link between consumption of green tea and reduced risk of dementia or mild cognitive impairment. A Chinese study [5] also presented evidence on the relationship between tea consumption and reduced cognitive impairment.

Cognitive disorders refer to mental health issues that affect learning, memory, perception, and problem-solving. The most common types of cognitive disorder include amnesia, dementia, and delirium. Data from the World Health Organization [6] estimate that around 47.5 million people are living with dementia which is a major neurocognitive disorder. This medical condition registers 7.7 million new cases every year. The main risk factors linked to dementia include advancing age and family history of dementia. By 2050, the number of people with dementia is expected to reach 135.5 million.

As of this writing, there are no medications [7] approved by the U.S. Food and Drug Administration to treat the onset of mild cognitive impairment (MCI), which likely leads to Alzheimer’s disease or other dementias. However, there are coping strategies that may help delay or prevent the progression of MCI to dementia.

As posited by Lei’s team, drinking tea is a simple and inexpensive measure which may protect yourself from cognitive decline. Regular exercise [8] is another way to combat MCI since it benefits your blood vessels – including those that nourish your brain. Having a diet rich in flavonols and omega-3 fatty acids [9][10] could also reduce the risk of dementia.
