Drinking regular cups of tea may help to prevent Alzheimer's disease, a study has found. Both green and black tea have similar effects to drugs developed to combat the development and progression of the disease and tests have shown that they have the potential to boost and enhance memory by inhibiting the activity of certain enzymes in the brain. The findings, which are published in Phytotherapy Research, may lead to the development of a "super cuppa" to help to combat Alzheimer's and, according to other work, cancer and heart disease too. Since preliminary evidence suggests that it would be necessary to drink about 10 cups a day to enjoy the full benefits, the aim is to develop a more concentrated brew of the active ingredients, said Ed Okello of the University of Newcastle Upon Tyne.
Drink more tea. I grew up on about six cups a day, more at weekends.
