Medscape reports a link between consumption of 3 or more servings of low-fat dairy products a day and Parkinson’s disease.

Over about 25 years of follow-up, the researchers documented more than 1000 cases of PD that were first self-reported and later confirmed by medical record review. They were then able to use these data to estimate the risk for PD according to how much dairy participants consumed.

Total dairy intake was not significantly associated with PD risk. However, intake of low-fat dairy foods was associated with an increased risk for the disease.

After adjustment for smoking, physical activity, coffee intake, body mass index, alcohol intake, and total caloric intake, the hazard ratio (HR) comparing people who consumed at least 3 servings of low-fat dairy per day with those who consumed none was 1.34 (95% confidence interval [CI], 1.01 – 1.79; P trend = .04).
