Does the Mediterranean diet protect against Parkinson’s disease and dementia with Lewy bodies?

High adherence to the Mediterranean diet was associated with 60–70% lower risk for prodromal Parkinson’s disease and lower incidence of Parkinson’s disease and dementia with Lewy bodies compared to individuals with the lowest adherence.
Each 1 unit increase in the Mediterranean diet score correlated to a 9–10% lower risk for Parkinson’s disease and dementia with Lewy bodies.
The authors concluded that the Mediterranean diet appears to offer some protection against the development of Parkinson’s disease and dementia with Lewy bodies, though further studies are needed to corroborate their findings.
