Researchers have found that regular consumption of tea could more than halve the risk of cognitive decline for the elderly people.
Many studies have already looked at the health benefits of tea: benefits to the bones or to the heart . The latest study, led by researchers at the University of Singapore, suggests that regular consumption of tea could reduce the risk of cognitive decline in the elderly, especially those with a genetic risk of Alzheimer's disease .
The researchers reached this conclusion by collecting data from 957 Chinese adults aged 55 and over.
Between 2003 and 2005, the team collected information on the participants' drinking of tea (quantity, frequency of consumption, types of tea, etc.). Then every two years until 2010, participants underwent standardized assessments that assessed their cognitive function. The researchers discovered 72 new cases of neurocognitive disorders among candidates between 2006 and 2010.

UP TO 86% LESS RISK OF COGNITIVE DECLINE
Compared to adults who rarely drank tea, those who consumed it regularly had a 50% lower risk of cognitive decline. In addition, among adults with the APOE e4 gene - which is associated with an increased risk of Alzheimer's disease - those who regularly drank tea had up to 86% less risk of cognitive decline.
The researchers also noted that the benefits on cognitive health were observed among consumers of green tea, black tea, and oolong tea. These benefits would be due to the anti-inflammatory and antioxidant properties of some tea active ingredients that can protect the brain from vascular damage and neurodegenerative diseases.
