A new study published in the journal Science of Food has revealed that regular consumption of green tea is linked to reduced white matter damage in the brains of elderly individuals, according to Tengri Life citing naukatv.ru.
The research, conducted by Japanese scientists, involved 8,766 participants over the age of 65. Data on the amount of green tea consumed was compared with MRI scan results, which assessed brain volume and the condition of white matter.
The findings indicated that those who drank three cups (one cup equals 200 milliliters) of green tea daily had three percent less white matter damage compared to those who consumed one cup. Drinking 7-8 cups a day reduced damage by six percent.
According to the researchers, even a three to six percent reduction in damage over the long term could significantly impact the quality of life for older adults and decrease the risk of serious diseases such as Alzheimer's or dementia.
The study also showed that elderly individuals without dementia who consume more green tea have less white matter damage in the brain. However, this correlation was not found in those who prefer coffee.
Scientists emphasize that green tea did not affect the volume of the hippocampus, which is associated with cognitive functions and memory, and was less effective for individuals with depression or a genetic predisposition to Alzheimer's disease.
Green tea contains less caffeine than coffee, making it more beneficial for maintaining normal blood pressure, the researchers note.
