title: Premorbid dietetic habits and risk for Parkinson's disease.
abstract: To evaluate the possible role of antioxidant (vitamins A, E, C, beta-carotene, zinc, selenium) or pro-oxidant (iron, copper, manganese) factors present in the diet, in the risk for Parkinson's disease (PD), we conducted a dietetic study (pre- and postmarriage) which included 91 foodstuffs. We interviewed separately 119 PD patients (64 males, 55 females, age 65.3 +/- 8.5 years, age at marriage 27.8 +/- 5.9 years) and their spouses (age 65.0 +/- 9.2 years, age at marriage 27.2 +/- 5.9 years) as the control group (C). Premarriage consumption for each foodstuff was classified into: (1) rarely of annually, (2) monthly, or (3) weekly; and postmarriage consumption (which included the period between age at marruage and age 40 years; only concordant answers were considered to be valid) into: (1) PD > Control, (2) Control > PD, and (3) PD = Control. The premarriage interview showed a trend towards a lower consumption of peas in PD patients as compared to controls. The postmarriage interview in PD patients showed a higher tendency for the consumption of rice, bluefish, liver paté and eggs, and a less consumption of tea than controls. We were unable to find any consistent trend towards a lower consumption of vitamins E and C during adulthood in PD patients, but they seemed to have eaten selenium-rich foodstuffs more frequently than controls. These results differ from those obtained by previous studies, and question the possible role of premorbid dietary habits on the risk for PD.
