Which beverage decreases the risk of Parkinson's disease?

New research unveils a significant correlation between caffeine consumption and a lowered risk of Parkinson's Disease (PD) for individuals with Asian gene variants linked to the disorder.

Up to 10% of Singapore's population carries one of the two known Asian gene variants associated with a 1.5 to 2 times higher PD risk.

The study involving 4,488 subjects disclosed that regular consumption of tea or coffee curtailed the risk of developing PD by four to eight times compared to non-caffeine drinkers who have the gene. Furthermore, the protective benefits appeared to escalate with higher caffeine doses, though even modest consumption below 200mg per day was beneficial.

The findings spotlight caffeine's potential in mitigating neuroinflammation and cell death, though the exact interaction with Asian PD gene variants remains to be explored.
