MIND and Mediterranean diets associated with later onset of Parkinson’s disease

By Stephanie Chow | January 13, 2021

A new study from UBC researchers suggests a strong correlation between following the MIND and Mediterranean diets and later onset of Parkinson’s disease (PD).

While researchers have long known of neuroprotective effects of the MIND diet for diseases like Alzheimer’s and dementia, this study is the first to suggest a link between this diet and brain health for Parkinson’s disease (PD). The MIND diet combines aspects of two very popular diets, the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) diet.

“The study shows individuals with Parkinson’s disease have a significantly later age of onset if their eating pattern closely aligns with the Mediterranean-type diet,” says the study’s senior author Dr. Silke Appel-Cresswell, associate professor in the UBC faculty of medicine’s division of neurology, and member of the Djavad Mowafaghian Centre for Brain Health. “There is a lack of medications to prevent or delay Parkinson’s disease, yet we are optimistic that this new evidence suggests nutrition could potentially delay onset of the disease.”

In a study of 176 participants, researchers looked at adherence to these types of diets, characterized by reduced meat intake and a focus on vegetables, fruits, whole grains and healthy fats, and the age of PD onset.

They found that close adherence to these diets coincided with later onset of PD in women of up to 17.4 years, and 8.4 years in men. The MIND diet showed a more significant impact on women’s health, whereas the Mediterranean diet did for men. The differences in these two diets are subtle, but could serve as clues to the impacts specific foods and micronutrients may have on brain health.

The different effects of diet adherence between sexes are noteworthy as approximately 60 per cent of those diagnosed with Parkinson’s disease are men.

“If we understand the sex differences between the MIND diet and Mediterranean diet then we might better understand the sex differences that drive Parkinson’s disease in the first place,” says lead researcher Avril Metcalfe-Roach, a PhD student at UBC’s Michael Smith Laboratories.

These findings springboard to other research questions that could have significant impacts on the understanding of PD.

“It drives home the connection between the gut and the brain for this disease,” says Dr. Brett Finlay, professor in the departments of biochemistry and molecular biology, and microbiology and immunology at UBC. “It also shows it’s not just one disease that healthy eating can affect, but several of these cognitive diseases.”

The research team plans to further examine the potential connection between the microbiome and its effect on the brain.
