Virgin Olive Oil May Be Better for Cognitive Function Than Refined Olive Oil

Over the last few years, researchers have come to understand that what we eat can have a large impact on our brain health. Known as the gut-brain axis , this collection of nerves that connect to the digestive system and brain plays a role in regulating mood and behavior , stress levels , and cognitive function .

In addition to the nerves, the gut microbiome is also involved in the wellness of the gut-brain axis. Previous research has linked a dysregulation of the gut-brain axis to irritable bowel syndrome (IBS) , gastroesophageal reflux disease (GERD) , inflammatory bowel disease (IBD) , chronic fatigue syndrome , multiple sclerosis (MS) , Alzheimer’s disease , Parkinson’s disease , and metabolic disorders .

Past studies have found that certain foods can help support the gut-brain axis, such as fermented foods , high-fiber foods , leafy greens , lean proteins , and healthy fats , such as extra-virgin olive oil (EVOO) .
