Olive oil has long been praised for its numerous health benefits, including its potential role in reducing the risk of developing dementia and other age-related cognitive decline. Several studies have suggested that incorporating olive oil into your diet may be associated with a lower risk of dying from dementia.

One study, published in the Annals of Clinical and Translational Neurology, found that older adults who consumed more olive oil had a significantly lower risk of developing dementia compared to those who consumed less. Researchers believe that the high levels of monounsaturated and antioxidants in olive oil may help protect brain damage and inflammation, which are believed to contribute to the development of dementia.

Another study, published in the journal Neurology, found that a Mediterranean-style diet rich in olive oil was associated with a lower risk of cognitive decline and dementia in older adults. The Mediterranean diet, which emphasizes whole grains, fruits, vegetables, fish, and olive oil, is believed to be beneficial for brain health due to its anti-inflammatory and antioxidant properties. Olive Oil is rich in monounsaturated fats and contains compounds with antioxidant activity that may play a protective role for the brain" says Marta Guasch-Ferrè an adjunct professor in nutrition at Harvard T.H. Chan School of Public Health.

In addition to its potential role in reducing the risk of dementia, olive oil has also been linked to numerous other health benefits, including improved heart health, including a reduced risk of dying from heart disease, reduced inflammation, and better weight management. Incorporating olive oil into your diet can be as simple as using it as a salad dressing, replacing mayonnaise with olive oil, cooking with it instead of butter or margarine, or drizzling it over vegetables or grilled meats.

Overall, the evidence suggests that adding olive oil to your diet may have a protective effect against dementia and other age-related cognitive decline. So go ahead and enjoy that delicious drizzle of olive oil – your brain will thank you!
