Olive oil: The secret protection against dementia and Alzheimer's!

A recent study shows that daily consumption of olive oil can provide significant protection against dementia. According to reports from Fulda newspaper and Focus Around 1.8 million people in Germany currently suffer from dementia, with this trend increasing in the coming years. Harvard University conducted an extensive long-term study with over 92,000 participants to examine how olive oil can influence the risk of dying from dementia.

Diet plays a central role in the prevention of dementia. This study found that people who consumed at least seven grams of olive oil (about a teaspoon) daily had a 28 percent lower risk of dying from dementia. In contrast, participants with lower olive oil consumption had higher mortality. In particular, replacing five grams of unhealthy fats such as margarine or mayonnaise with olive oil was able to reduce the risk of dementia by up to 14 percent.

The role of olive oil in the diet

Olive oil is rich in monounsaturated fatty acids, polyphenols and vitamin E, which help promote cardiovascular health and may protect against cognitive decline. The German Society for Nutrition recommends a daily oil consumption of 10 to 15 grams. However, Oekotest points out differences in the quality of olive oils, which can influence the health benefits.

Additionally, a Mediterranean diet rich in fruits, vegetables, fish and vegetable oils has been found to be protective for brain health. Consuming black and green tea is also recommended as these drinks also contain polyphenols that promote blood flow to the brain.

The Harvard study also highlights other risk factors for dementia, including lack of exercise, head injuries, alcohol, high blood pressure and diabetes. According to the German Alzheimer Society, the average lifespan after an Alzheimer's diagnosis is around eight years, with people with advanced dementia being more susceptible to infectious diseases.
