Mediterranean diet and gut microbiome link to neuroprotection under review
A narrative review published in the journal Nutrients suggests that while the Mediterranean diet is linked to slower cognitive decline and reduced dementia risk, direct human evidence connecting these benefits to gut microbiome changes remains limited.
Researchers examined how dietary components interact with the gut microbiome, the blood-brain barrier, and systemic inflammation to influence neurodegeneration in conditions such as Alzheimer’s and Parkinson’s disease. The gut-brain axis serves as a communication pathway involving microbial metabolites, immune mediators, and hormones.
When microbial diversity drops, intestinal permeability can increase, allowing pro-inflammatory components to enter systemic circulation and potentially compromise the blood-brain barrier. The Mediterranean diet, characterized by high intakes of fruits, vegetables, whole grains, legumes, nuts, and extra-virgin olive oil, provides bioactive compounds that may mitigate oxidative stress and neuroinflammation.
