Brain health
Studies show that olive oil enhances cognitive functioning and reduces cognitive decline. Olive oil's benefits for brain health stem from its rich content of monounsaturated fats, particularly oleic acid, which support vascular health and cognitive function, and its potentially high concentrations of antioxidants, including polyphenols like oleocanthal, which combat oxidative stress and inflammation, factors linked to neurodegenerative diseases. Studies indicate that olive oil consumption may lower the risk of Alzheimer's and prevent and treat Parkinson's, enhance brain plasticity, and improve cognitive performance in older adults. One study found that people who consumed half a tablespoon of olive oil daily had a 28% reduced risk of dying from dementia. It also increases serotonin levels in the brain, enhancing mood and lowering anxiety.
