According to researchers from Shiga University of Medical Science in Japan, contaminants found in cow's milk may increase the risk of developing Parkinson's disease.

As TIME Magazine reports, lead researcher Robert Abbott and his team of colleagues took advantage of an environmental scandal in Hawaii in the 1980s to investigate the connection between milk consumption and Parkinson's.

Around the same time, there was also a study of heart disease among Japanese-American men being conducted. Over 8,000 men were involved, and they were followed from mid-life to death in the study.

The participants provided detailed information about what they ate, including how much milk they drank. Some even agreed to donate their brains for research upon death.
