A new study has confirmed a relationship between consuming large amounts of dairy products and an increase in the rate of Parkinson's disease in men, but the reason for this relationship remains a puzzle.

Researchers found that among more than 130,000 US adults followed for nine years, those who ate the largest amount of dairy foods had an increased risk of developing Parkinson's disease, a disorder in which movement-regulating cells in the brain die or become impaired.
