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 9 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.
There was a clear pattern seen among men, whose Parkinson's risk increased in tandem with consumption of diary, particularly milk. The results were more ambiguous among women, however.
Men with the highest levels of dairy consumption were 60 percent more likely to develop the disease than those who consumed the least amounts of dairy, the study found.
