Other Health Benefits of Extra Virgin Olive Oil
Although mostly studied for its effects on heart health, olive oil consumption has also been associated with a number of other health benefits.
Cancer is a common cause of death, characterized by uncontrolled growth of cells in the body.
Studies have shown that people in the Mediterranean countries have a fairly low risk of cancer and some have speculated that olive oil has something to do with it (27).
Whether olive oil actually helps prevent cancer has yet to be studied in human controlled trials.
Olive Oil and Alzheimer’s Disease
Alzheimer’s disease is the world’s most common neurodegenerative disease and a leading cause of dementia.
One feature of Alzheimer’s is a buildup of protein tangles called beta amyloidplaques, in certain neurons in the brain.
A study in mice showed that a substance in olive oil can help to clear these plaques from the brain (35).
Bottom Line: There is preliminary evidence that olive oil can help fight cancer and Alzheimer’s disease, although this needs to be confirmed in human controlled trials.
