Higher caffeine and urate levels may be protective against Parkinson’s, new evidence suggests

Caffeine and urate have both been associated with a reduced risk of Parkinson’s disease (PD) in multiple studies. More recently, analysis of data from the Harvard Biomarker Study (HBS) has provided more evidence towards this, with researchers reporting that lower levels of caffeine consumption and lower blood urate levels are inversely associated with PD. The study, published in the Journal of Parkinson’s Disease, investigated whether these reduced risk factors are associated with PD in individuals from the HBS. “Both caffeine and urate possess neuroprotective properties via adenosine receptor antagonist and antioxidant actions, respectively. They both have protective properties in animal...
