Scientists have shown that green tea extract can be considered a natural remedy, and can benefit cognitive functioning and memory – especially working memory (functional memory or short-term memory).
This tea is processed from the dried leaves of Camellia sinensis, an evergreen shrub. The teas that come from the same plant are green tea, black tea, and oolong tea. Green tea is prepared by steaming the freshly cut leaf. Green tea is consumed mostly in the following countries: China, Japan, and the countries of North Africa and the Middle East. Unlike black and oolong tea leaves, green tea leaves do not undergo a fermentation process. As a result, green tea has high levels of antioxidant compounds.
The people involved in this research conducted a study with the help of 12 healthy people to receive either a milk-based drink containing 27.5 grams of green tea extract or a milk-based drink without green tea. , while undergoing magnetic resonance imaging (MRI) or magnetic resonance imaging (MRI).
This study looked at the effects of this tea on working memory and the connectivity between the frontal lobe, which plays an important role in memory retention, and the parietal lobe, which plays an important role in processing the senses, such as touch and taste.
They also showed that green tea extract increased working memory and connectivity between the frontal and parietal lobes of the brain. This increase in connectivity has been linked to an improvement in task performance.
In conclusion, green tea has a great influence on mental function and memory. It could play an important role in possible treatment options for people with mental disorders or memory loss. Further research is needed to confirm and deepen these results.
