Your Brain on Olive Oil
Hmm... I use a lot of olive oil...
Olive oil modifies how your gut microbiome communicates with your brain. Olive oil’s beneficial effects on the human brain and body are likely related to the presence of the polyphenols hydroxytyrosol (HT) and Oleic acid (OA). HT protects cells that are under oxidative stress. OA is a monounsaturated omega-9 fatty acid that is generally higher in olive oil than vegetable fats. It has beneficial effects on blood cholesterol levels.
In the current study of an animal model of MS, EVOO, as well as OA or HT alone, demonstrated potent anti-inflammatory and antioxidant effects.
So, yes, your brain benefits a lot from adding olive oil to your diet and these benefits originate in response to the changes that olive oil makes to your gut microbiome. Olive oil should become a big part of the diet for anyone with an aging brain.
