Drinking tea every day reduces your dementia risk by half

Aging happens differently for each person, but it is a common fear for most that they will be affected by cognitive decline as they get older. According to the World Health Organization (WHO), 55 million people worldwide have dementia, with the number expected to increase to 78 million by 2030 and 139 million by 2050. Unfortunately, unlike cardiovascular disease, the steps are to keep your brain in good shape. able shape may be less clear. However, according to a study, there are signs that drinking this popular drink every day can reduce your risk of developing dementia by half. Read on to see what to put in your cup more regularly.

In a study published in Journal of Nutrition, Health & Aging in December 2016, a team of researchers from the National University of Singapore set out to investigate whether regular consumption of tea could have an effect on the onset of dementia. To do this, the researchers gathered 957 participants from China aged 55 years or older to conduct a longitudinal study.

The results showed that those who drank tea every day saw their risk of developing dementia reduced by 50 percent. In the case of participants carrying the APOE e4 gene, which puts them at a higher risk of developing Alzheimer’s disease, daily tea drinkers saw their risk of cognitive decline drop by as much as 86 percent.

According to researchers, the results suggest that drinking tea every day could provide an affordable and easy way to combat the onset of a largely paralyzing disease. “Despite high-quality drug trials, effective pharmacological treatment for neurocognitive disorders such as dementia is still elusive, and current prevention strategies are far from satisfactory.” Feng Lei, said the study’s author and an assistant professor from the Department of Psychological Medicine at the National University of Singapore (NUS) Yong Loo Lin School of Medicine, in a statement. “Tea is one of the most widely consumed beverages in the world. The data from our study suggest that a simple and inexpensive lifestyle measure such as daily tea drinking can reduce a person’s risk of developing neurocognitive disorders in late life.”

Feng concluded: “While the study was conducted on Chinese elderly, the results could also apply to other races. Our results have important implications for dementia prevention.”

Researchers also found that the health benefits of drinking tea were not limited to one type. All freshly brewed leaves – including black, green and oolong – were shown to have the neuroprotective effects found in the study.

“Based on current knowledge, this long-term benefit of tea consumption is due to the bioactive compounds in tea leaves, such as catechins, theaflavins, thearubigins and L-theanine,” Feng explained. “These compounds exhibit anti-inflammatory and antioxidant potential and other bioactive properties that can protect the brain from vascular damage and neurodegeneration. Our understanding of the detailed biological mechanisms is still very limited, so we need more research to find definitive answers.”

Other research has found that health-promoting properties are not just tea. A study from 2018 from the Krembil Brain Institute, which was published in the journal Boundaries in neuroscience, set out to investigate the theoretical link between coffee consumption and a reduced risk of developing Alzheimer’s. The researchers decided to test the compounds found in various beans, including light roasts, dark roasts and decaffeinated coffee.

The team discovered that the beans contained phenylindanes, a chemical compound that prevents the build-up and clumping of proteins known as beta-amyloid and tau, which are known to lead to Alzheimer’s. As a longer roast leads to an increase in the amount of phenylindanes, the researchers concluded that dark roasted coffee provided better protection against the neurological condition.

Interestingly, the researchers also found that the amount of caffeine – which has long been theorized to help prevent dementia – does not affect the outcome. “The decaffeinated and de-decaffeinated dark rose both had identical strengths in our first experimental test,” Ross Mancini, PhD, a fellow in medical chemistry, said in a statement. “So we observed early on that its protective effect could not be due to caffeine.”
