A recent study on the effects of olive oil on dementia and the prevention of Alzheimer’s

Recent research shows that daily use of olive oil can significantly reduce the risk of dying from dementia – by up to one-third. The Mediterranean diet as a whole supports brain health and may slow the development of Alzheimer's disease.
Here are the key findings from the latest studies:

Effect of olive oil on dementia mortality
 - A Harvard University study followed 93,000 people over 28 years.
 - Those who consumed an average of 7 grams of olive oil per day were 33% less likely to die from dementia than those who did not use it at all.
 - The effect was observed regardless of other dietary habits.
 - In particular, replacing margarine or mayonnaise with olive oil was associated with a lower risk.

Mediterranean Diet and Alzheimer's Prevention
 - The Mediterranean diet, which includes plenty of vegetables, fruits, whole grains, fish, and olive oil, has been associated with better cognitive health.
 - As early as 2006, a study suggested that following this diet could reduce the risk of Alzheimer's.
 - A 2018 study, on the other hand, showed that the diet could slow the progression of the disease in those who already have early symptoms. Possible mechanisms of action
 - Olive oil is rich in polyphenols and antioxidants, which may protect brain cells from inflammation and oxidative stress.
 - It also supports cardiovascular health, which is important for brain blood flow and oxygen supply. Daily use of olive oil
 - Daily consumption of olive oil (about ½ tablespoon) can be a simple and effective way to support brain health.
 - The Mediterranean diet as a whole provides versatile protection against cognitive decline.
