American researchers discovered recently that a diet rich in Extra Virgin Olive Oil, a key component of the Mediterranean Diet (EVOO), can help prevent cognitive decline and memory loss. This helps protect the brain from related conditions such as:
- Alzheimer's Disease
- Memory loss
Extra Virgin Olive Oil could be used to treat Alzheimer's disease.
These findings were called "Extra virgin olive oils improve cognition, neurological pathology and neuropathology in 3xTg mice." Autophagy plays a role in this study. Domenico Pratico (a professor in Pharmacology and Center for Translational Medicine) published them.
This study also looked at the effects of extra virgin oil consumption on Alzheimer’s disease incidence.
Recent studies have shown that Extra Virgin Olive Oil has brain protection, phenolic substances, and antioxidant properties.
To demonstrate the main features and symptoms of Alzheimer's Disease, scientists used genetically engineered mice.
- Memory impairment
- Amyloid plaque buildup
- Neurofibrillary Tangles
Amyloid plaque is a protein buildup that occurs in excess in the brain. It can also cause brain cell death.
The mice were split into two groups. The first group was given a standard diet, while the second was given extra virgin olive olive oil from Apulia.
After six months, the mice were tested for cognitive performance.
Researchers found that mice who were fed Extra Virgin Olive Oil rich diets had higher levels of peptides than mice who were fed the baseline diet.
The brains showed decreased tau phosphorylation and neuropathology.
These are all important features of Alzheimer's disease. This study showed that EVOO (Extra Virgin Olive Oil) had a positive effect.
Researchers concluded the study supported the positive longitudinal data and cross-sectional data. Most importantly, the biological reasoning to suggest Extra Virgin Olive Oil as a therapeutic option for Alzheimer's Disease prevention or halting might also be supported by the study
