Dietary antioxidants and risk of Parkinson's disease in two population-based cohorts.
Mov Disord. 2017 Nov; 32(11):1631-1636.MD

Abstract

BACKGROUND

A neuroprotective effect of dietary antioxidants on Parkinson's disease (PD) risk has been suggested, but epidemiological evidence is limited.

OBJECTIVES

To examine the associations between intake of dietary antioxidant vitamins and total antioxidant capacity and risk of PD.

METHODS

We prospectively assessed the relationships of dietary antioxidant vitamins C and E, β-carotene, and total antioxidant capacity with PD risk in two population-based cohorts (38,937 women and 45,837 men).

RESULTS

During a mean 14.9-year follow-up period, 1,329 PD cases were identified. Dietary intake of β-carotene was associated with a lower risk of PD (hazard ratio: 0.86; 95% confidence interval: 0.78-0.95; Ptrend < 0.01 for women and hazard ratio: 0.91; 95% confidence interval: 0.84-0.99; Ptrend = 0.05 for men). An inverse association between dietary vitamin E and PD risk was found in women (hazard ratio: 0.87; 95% confidence interval: 0.79-0.96; Ptrend = 0.02). Dietary intake of vitamin C was inversely associated with PD risk in women at borderline significance (hazard ratio: 0.91; 95% confidence interval: 0.83-1.00; Ptrend = 0.04). There was no association between dietary total antioxidant capacity and PD risk in either women (hazard ratio: 0.93; 95% confidence interval: 0.84-1.02; Ptrend = 0.35) or men (hazard ratio: 1.00; 95% confidence interval: 0.93-1.07; Ptrend = 0.97).

CONCLUSION

Intake of dietary vitamin E and β-carotene was associated with a lower risk of PD. © 2017 The Authors. Movement Disorders published by Wiley Periodicals, Inc. on behalf of International Parkinson and Movement Disorder Society.
