Tea May Help Prevent Dementia

The health benefits of tea—largely due high levels of antioxidants—are well documented. Research shows that drinking tea regularly can help reduce the risk for many common health problems, including heart disease, diabetes, and cancer. Now, a new study suggests that tea also may prevent cognitive decline in older adults—especially those at increased risk for Alzheimer's disease.

For this recent study, researchers collected and analyzed data about tea consumption and cognitive function in 957 Chinese adults over the age of 55. According to researchers, regular tea drinkers had a 50 percent lower risk of cognitive decline compared to those who rarely drank tea. In older adults with a genetic risk for Alzheimer's—those who possess the APOE e4 gene—tea drinkers had an 86 percent lower risk.

The cognitive benefits were observed with black tea, green tea, and oolong tea—teas that are brewed from tea leaves. More research is needed, but the brain benefits of tea may be related to compounds that reduce vascular damage and neurodegeneration.
