Abstract

The study investigated features of life-style and dietary habits early and late in life of patients with idiopathic Parkinson's disease (IPD). Seventy-one patients and 103 controls were interviewed personally with a structured questionnaire. Living in villages during primary school time was significantly more frequent among patients, and in the urban environment patients had lived less frequently in larger-sized towns. Mushroom harvesting during childhood was more frequent among patients. No difference between patients and controls was found in childhood water supply, habits of fishing in the countryside or at the seaside, and eating such fish. Actual food preference in patients was greater for almonds and plums, while no difference was found in the actual intake of mushrooms, peanuts, oil-dressed salad, fish and animal offals. The study did not indicate a higher consumption of foods known to harbour heavy metals and pesticides in IPD patients either long before or during the disease. Reduced consumption of foodstuffs rich in vitamin E, as reported previously for premorbid patients, is no longer observed in patients with overt disease.
