We all have heard how green tea is good for weight loss, but a study conducted by USA National Parkinson Foundation Centers of Excellence for Neurodegenerative Diseases Research and Department of Pharmacology, found both experimental and epidemiological evidence that flavonoid polyphenols, particularly from green tea and blueberries, improve age-related cognitive decline and are neuroprotective.
This essentially means that the polyphenols in green tea prevent and reduce oxidative stress from damaging the brain. This protection can help reduce brain damage that could lead to mental decline and brain diseases like Parkinson’s, Alzheimer’s and dementia.
Furthermore, green tea extract can decrease the action of heavy metals like iron and copper, both of which can damage brain cells. Id.
It’s also been shown to help memory by enhancing the connection between different parts of the brain.
One study had 12 people drink a soft drink containing 27.5 grams of green tea extract or a placebo. Then, while the participants worked on memory tests, brain images were obtained to assess brain function.
The green tea extract group showed an increase in brain function and improved task performance, compared to the placebo group Id.
Green tea extract has been shown to have a positive effect on brain health and memory, and may help protect against brain diseases. So whether you want to improve your general health or decrease your risk of disease, green tea extract is an easy way to add health-boosting antioxidants to your diet.
