High β-carotene dietary intake reduces Parkinson's disease among women

Objectives:
Does high-dose dietary intake of vitamin E, β-carotene or vitamin C reduce risk of Parkinson's disease?

Study design:
This review article included 13 observational studies.

Results and conclusions:
The investigators found no significant association between high-dose vitamin C dietary intake and the risk of Parkinson's disease compared with low-dose vitamin C dietary intake [RR = 0.98, 95% CI = 0.89 to 1.08].

The investigators found compared with low-dose dietary intake, high-dose dietary intake of vitamin E significantly reduced risk of Parkinson's disease with 13% [RR = 0.87, 95% CI = 0.77 to 0.99].

The investigators found compared with low-dose dietary intake, high-dose dietary intake of β-carotene significantly reduced risk of Parkinson's disease among women with 22% [RR = 0.78, 95% CI = 0.64 to 0.96].

The investigators concluded both high-dose dietary intake of vitamin E and β-carotene (beta-carotene) reduce risk of Parkinson's disease.
