A diet rich in olive oil reduces the risk of Alzheimer’s. Olive oil, especially extra virgin olive oil, has been shown to have significant benefits for brain health and could help reduce the risk of developing dementia, including Alzheimer’s. Below are some key points on this topic:
Predimed Study: The Predimed study (Prevention with Mediterranean Diet) is one of the most prominent trials that has investigated the effects of olive oil on brain health. Published in the Journal of Neurology, Neurosurgery & Psychiatry, this study demonstrated that a Mediterranean diet enriched with extra virgin olive oil reduced the risk of mild cognitive impairment and dementia.
Antioxidants and Anti-inflammatory Properties: Olive oil contains antioxidants and anti-inflammatory compounds, such as polyphenols, which can have a positive impact on brain health. These compounds protect nerve cells from oxidative stress and inflammation, processes associated with the development of Alzheimer’s.
Monounsaturated Fatty Acids: The monounsaturated fatty acids present in olive oil, especially oleic acid, have also been the subject of studies suggesting benefits for brain health. These fatty acids can improve vascular function and reduce the risk of cardiovascular diseases, which in turn are linked to cognitive decline.
Effects on Tau Protein: Research has shown that olive oil can influence the accumulation of tau protein, a common feature in the brains of people with Alzheimer’s. It is believed that the components of olive oil can help reduce the formation of neurofibrillary tangles associated with the disease.
Regulation of Brain Inflammation: Chronic inflammation in the brain is implicated in Alzheimer’s. Studies have suggested that the compounds in olive oil can modulate brain inflammation, thus contributing to the prevention of neurodegenerative diseases.
In summary, including extra virgin olive oil in the diet could be beneficial for brain health and reduce the risk of dementia.
It is important to remember that a balanced diet and other lifestyle factors also play a crucial role in preventing neurodegenerative diseases. So, don’t hesitate to enjoy a good spoonful of this healthy oil! In the Predimed study, which focuses on prevention with a Mediterranean diet, it is recommended to consume between four and five tablespoons of extra virgin olive oil per day in Spain. This is significantly more than the 7 grams daily considered as high consumption in the U.S. The study showed improved cognitive performance in individuals with a diet rich in olive oil, both in verbal fluency and memory tests. So, don’t hesitate to enjoy this healthy dressing!
