Rich in antioxidants and good fats, olive oil is a staple of the Mediterranean diet. Now new research shows that half a tablespoon of olive oil a day can help reduce the risk of dementia.
In its context A study published in JAMA Network researchers analyzed data from more than 92,000 participants over 28 years. Participants reported their dietary habits and olive oil consumption every four years.
It turned out that those who consumed more than seven grams (about half a tablespoon) of olive oil a day were 28% less likely to die from dementia than those who rarely or never consumed it.
However, it should be noted that this is an observational study that can identify associations but not cause and effect.
In other words, it’s unclear whether olive oil itself directly reduces the risk of dementia-related death, or whether other lifestyle factors play a role.
How does olive oil help cognitive health?
While there is no magic food that will protect us from dementia, including olive oil in your diet can provide many cognitive health benefits.
“We have known for some time that olive oil, like other sources of unsaturated fat, is important for various aspects of cardiovascular health, including lowering cholesterol levels, blood pressure, and the risk of heart disease,” the researchers note.
The link between heart and brain health is also confirmed by scientific research.
For example, The study was published in the Journal of the American Heart Association found that people with a higher risk of heart disease had worse cognitive function than those with a lower risk, suggesting that what’s good for the heart is also good for the brain.
A healthy diet in general is important
Experts emphasize that it is important to focus on our eating habits as a whole rather than relying unilaterally on specific foods. Remember this brain health depends on diet and various factors such as physical activity and sleep.
Start with a healthy diet, because following a heart-shielding nutritional plan can also benefit brain function, reducing the risk of cognitive decline and dementia.
