This study investigated the association of fat intake with the risk of Parkinson disease. The study lasted for six years and included 5,289 subjects, (aged 55 years and over), who were free of dementia and Parkinsons at the start of the study.
The study found:
(a) For every 13.2 grams daily increase in fat consumption there was a 31% decreased risk of Parkinsons Disease.
(b) For every 7.2 grams daily increase in saturated fat consumption there was a 18% decreased risk of Parkinsons Disease.
(c) For every 60 mg daily increase in cholesterol consumption there was a 19% decreased risk of Parkinsons Disease.
A higher consumption of saturated fat and cholesterol is associated with a lower risk of Parkinsons Disease.
