Previous studies have shown that regular consumption of green tea can help individuals avoid certain heart diseases and cancer.
A new report reveals that the beverage, which contains unfermented leaves and powerful antioxidants, can also help protect people from developing Alzheimer's disease and other forms of dementia. Researchers from Newcastle University conducted the study, which was published in the journal Phytomedicine.
The team of scientists, led by Dr. Ed Okello, found that the properties of green tea protected brain cells from toxic compounds that can cause dementia. Antioxidant polyphenols, which are present in this type of tea, were shown to protect the brain from hydrogen peroxide and the protein beta-amyloid, which play a significant role in the development of Alzheimer's.
"What was really exciting about this study was that we found when green tea is digested by enzymes in the gut, the resulting chemicals are actually more effective against key triggers of Alzheimer's development than the undigested form of the tea," said Okello.
The Centers for Disease Control and Prevention reports that about 16 percent of individuals who receive nursing home care have Alzheimer's.
