Alzheimer's disease is the sixth leading cause of death in the United States, with over 5.4 million people currently living with the disease. This means that over 15 million caregivers have provided over $17 billion in free care. This year, the disease is projected to cost the nation over $200 billion, with healthcare costs expected to rise to over $1 trillion by 2050. Unfortunately, there is currently no cure for the disease, but new breakthroughs are being discovered every day.
Recent research has highlighted the importance of omega-3 fatty acids, DHA and EPA, as well as diet and exercise, in preventing the disease. But now, a new player has entered the ring – olive oil.
Do you know someone, usually an older adult, whose mood changes from day to day or even from moment to moment? Do they find simple tasks difficult, like playing Bridge or balancing a checkbook? Do they often get lost going to the store or to their favorite eatery? Have they lost interest in things that they used to love? Do they commonly misplace items and have no idea where they put them? If you answered "yes" to any of these questions, then chances are they may be experiencing some form of cognitive impairment, dementia, or even the early stages of Alzheimer’s disease.
Research has shown that several nutrients can slow the degeneration of brain cells. Studies have highlighted the benefits of omega-3 fatty acids, cutting back on certain fats (trans-fats), exercise, and berries, as ways to slow the progression. However, a new study has shown that olive oil, the #1 oil used for cooking, may reduce the risk for Alzheimer’s disease due to a specific compound found in it – oleocanthal.
- The study showed that high olive oil intake may be linked to a reduction in risk for Alzheimer’s, but the reason for this reduction was unclear until now. The study revealed that oleocanthal may have the ability to clear beta-amyloid proteins from the brain, thus reducing the risk. Beta-amyloids are proteins that are present in high concentrations in the brains of people with Alzheimer’s and may be the reason for the eventual neurodegenerative processes that destroy brain cells.
- The study found that when oleocanthal was administered to mice brain cells, it activated a specific pathway that increased the expression of major transport proteins in the brain. This resulted in an increased clearance of beta-amyloid proteins from brain cells and an increase in brain efflux index. They also showed that oleocanthal may have the power to break down the beta-amyloid proteins by increasing the activity of beta-amyloid enzymes.
- The study concluded that "these findings provide experimental support that potential reduced risk of AD associated with extra-virgin olive oil could be mediated by enhancement of AB clearance from the brain." This research suggests that olive oil has many potential health benefits, including intestinal health, fat loss, and reducing inflammation, and it should be the preferred choice when it comes to promoting good health. Additionally, olive oil may reduce the risk of Alzheimer’s disease.
In conclusion, Alzheimer’s disease is a prevalent and devastating disease that affects millions of people. Unfortunately, there is currently no cure for the disease. However, new research suggests that olive oil, due to its oleocanthal content, may help reduce the risk of Alzheimer’s disease. Therefore, olive oil should be the preferred choice for cooking, salads, and as a topper, as it provides a multitude of health-promoting benefits.
It's important to note that while the study mentioned above shows promising results, more research is needed to fully understand the potential benefits of olive oil for brain health and Alzheimer's disease prevention. Additionally, it's important to consume olive oil in moderation as it is still a high-calorie food and excessive consumption may lead to weight gain.
With this, taking care of your brain health is crucial, especially as you age. While there is currently no cure for Alzheimer's disease, research shows that there are steps you can take to potentially reduce your risk, including consuming a healthy diet, engaging in regular exercise, and potentially incorporating olive oil into your diet. As always, it's important to consult with your healthcare provider before making any significant changes to your diet or lifestyle.
