A pesticide found in milk may be associated with signs of Parkinson’s disease, according to a study published in the medical journal of the American Academy of Neurology.
The link between dairy products and Parkinson’s disease has been found in other studies. Our study looked specifically at milk and the signs of Parkinson’s in the brain,” said study author R. D. Abbott, PhD, with the Shiga University of Medical Science in Otsu, Japan.
For that review, 449 Western-American guys by having an average age of 54 who enjoyed in the Honolulu-Japan Aging Research were implemented for over 30 years and until death, after which autopsies were conducted. Assessments checked out whether brain tissues had been lost within the substantia nigra (a part of the brain), which happens in Parkinson’s illness and certainly will start decades before any signs begin. Scientists also tested in 116 brains the amount of deposit of a pesticide named heptachlor epoxide.
The pesticide found in milk was discovered at high quantities in the early 1980s in Hawaii, where it had been used in the pineapple business. It was taken off use within the USA around that point and was used to destroy insects. The pesticide can also be present in well water.
The research discovered that nonsmokers who drank over two glasses of milk per day had 40 percent fewer brain cells than people who consumed significantly less than two glasses of milk daily for the reason that section of the brain. For many who were smokers at any level, there is no relationship between milk consumption and lack of brain tissues. Previous reports show that individuals who smoke have a lower-risk of developing Parkinson’s illness.
Deposits of heptachlor epoxide were within 90-percent of people who drank the most milk, in comparison to 63 percent of these who didn’t drink any milk. Abbott noted that the analysts don’t have proof that the dairy contributors drank comprised heptachlor epoxide. He also stated the study does not present that the dairy or pesticide intake cause Parkinson’s illness; it only shows an association.
There are several possible explanations for the association, including chance. Also, milk consumption was measured only once at the start of the study, and we have to assume that this measurement represented participants’ dietary habits over time,” according to Dr. Honglei Chen, MD, PhD, with the National Institute of Environmental Health Sciences and a member of the American Academy of Neurology, who wrote a corresponding editorial.
Chen noted the research about the pesticide found in milk is an excellent example of how epidemiological studies can contribute to the search for causes of Parkinson’s disease.
