A cup of tea a day can prevent senile

One of the wishes of every person is to be able to keep a good memory until the old age. However, keeping memories is not easy. The risk of dementia, overall memory loss in elderly is still large.

However, there is a way that might help you avoid the risk of dementia. A study from the National University of Singapore found that drinking tea could reduce the risk of cognitive impairment by up to 50 percent. The decline could even reach 86 percent for adults who have a genetic risk of Alzheimer's disease.

The study was conducted in 957 elderly ethnic Chinese aged over 55 years. "Although the study was conducted on Chinese ethnic elderly, the results can also be applied to other ethnic groups. Our findings have important implications for the prevention of dementia, "said Feng Lei, a researcher.

He said that despite the high-quality drug trials, effective pharmacological therapy for brain neurological disorders such as dementia remains elusive and current prevention strategies are far from satisfactory.

"Tea is one of the most consumed beverages in the world. Data from our study suggest that simple and inexpensive lifestyles such as daily tea can reduce a person's risk of neurocognitive impairment in the elderly, "he said.

The results of this study were published in the Journal of Nutrition, Health & Aging. Respondents provided information about the amount of tea they drank from 2003 to 2005. The researchers also assessed their cognitive function every two years until 2010.

They also collected data on lifestyle, medical conditions, and physical and social activities. Feng said, long-term benefits are obtained because there are bioactive compounds in tea leaves, such as catechins, theaflavin, thearubigins and L-theanine.

"These compounds show the potential for anti-inflammatory and antioxidants and other bioactive properties that can protect the brain from blood vessel damage and neurodegeneration," Feng said.

However, he said, the understanding of the biological mechanism in detail is still very limited, requiring more research to find definitive answers.
