JAKARTA - A study found drinking three cups of green tea a day could help prevent dementia in the future. Recent research from Japan shows that consuming three cups of green tea a day can significantly reduce the risk of this disease.

Reporting from the Unilad page, researchers found adults who regularly drink green tea had fewer white matter lesions in their brains. This white matter lesion is often associated with a decrease in cognitive function and development of dementia.

This study involved nearly 9,000 adults who were asked to fill out a questionnaire about their drinking intake habits. Then, the results are analyzed using brain scans. The results show drinking three cups of green tea or more per day can help prevent dementia.

Previous research also cited the benefits of drinking green tea to prevent dementia. An analysis in 2022 showed the risk of developing dementia decreased by about 6% for each cup of green tea drunk.

Green tea, which comes from the sinensis Camellia plant, has been consumed for more than 5,000 years, especially in East Asia. These drinks are rich in antioxidants such as katechin and epigallocatechin gallate, which are known to have various health benefits.

In addition to helping prevent dementia, green tea also has anti-inflammatory properties and protects the body's cells. This has the potential to reduce the risk of other diseases such as cancer, diabetes, heart disease, high blood pressure, high cholesterol, stroke, digestive problems, bone disorders, and metabolic problems.

A study in 2023 found that people who drink two to four cups of green tea a day have a risk of 24% lower stroke. Another study in 2010 conducted in a laboratory using animal cells also shows that antioxidants in green tea can protect nerve cells from damage related to dementia and Alzheimer's.

"Green tea has long been used in East Asia as a treatment for various diseases, including joint inflammation and weight loss. However, it is recommended to drink it in moderate quantities, so that green tea lovers can continue to enjoy it." said Alison Hornby, a nutritionist and spokesman for the British Diet Association (BDA).
