Health benefits of green tea are boosting brain function in rats, according to a study published online in the journal Cell Reports.
The researchers used a new strain of green teas called Dandelion Green tea and a strain of the blue tea extract Kojima, which are both green tea components.
The results showed that the tea extracts helped the animals’ brains produce fewer beta amyloid beta protein fragments, which cause Alzheimer’s disease, and the animals were also less susceptible to brain inflammation.
The researchers said they found the compounds were beneficial because they protect the brain against inflammation and are believed to increase memory, cognitive function and brain function.
“These results indicate that green tea extract improves memory and improves cognition,” said study author Dr. Gabor Cekic, of the Institute for Advanced Medical Sciences at the University of Toronto.
“It could help us to understand how green tea and tea extracts might help the brain to regulate cognitive functions.”
Dr. Cekich said he was surprised that the brain benefits were so strong when compared to other green tea, which were found to have a moderate to weak cognitive benefit.
“I think this was really surprising because we thought that green teapots would be more beneficial than other green teacakes,” he said.
Dr. Zulfiqar Makhdoom, a research scientist at the Harvard Medical School and a professor of neuropsychiatry, said that while the study did not prove that green and blue teas have a beneficial impact on the brain, it does support the idea that the compounds have cognitive benefits.
“If green tea is beneficial for the brain and it is beneficial in other parts of the body, then it might be possible to combine green tea with other treatments to prevent Alzheimer’s and other degenerative diseases,” Dr. Makhdmoom said.
