Drinking as little as three-quarters of a cup of this one tea each day may cut the risk of developing Parkinson’s disease by as much as 71 percent, according to a new study conducted by researchers from the National Neuroscience Institute in Singapore and published in the American Journal of Epidemiology.Tags: health news, Parkinson's disease
Parkinson’s disease is a degenerative disorder that disrupts movement and balance.
Researchers examined the incidence of Parkinson’s disease in 63,257 Chinese women and men, and compared it to their intake of various beverages as determined by in-person questionnaires. The researchers found that higher caffeine intake was associated with a 45 percent lower risk of Parkinson’s disease.
Even after they adjusted for this effect, however, the researchers found that those who drank 23 or more cups of black tea each month (less than one per day) still had a 71 percent lower risk of Parkinson’s disease than those who drank less.
“Black tea, a caffeine-containing beverage, showed an inverse association with Parkinson’s disease risk that was not confounded by total caffeine intake or tobacco smoking,” the authors wrote. “[This suggests that] ingredients of black tea other than caffeine appear to be responsible for the beverage’s inverse association with Parkinson’s disease.”
