A recent study published in JAMA Network Open has found a potential link between consuming olive oil and a lower risk of death related to dementia. The study, which tracked 92,383 individuals over a 28-year period, found that consuming at least 7 grams of olive oil a day was associated with a 28% lower risk of death from dementia-related causes.
The study, conducted using data from the Nurses’ Health Study and Health Professionals Follow-Up Study, divided olive oil consumption into four categories based on daily intake. The results showed that those who consumed more than 7 grams of olive oil a day had a significantly lower risk of death from dementia-related causes.
Olive oil is known for its high levels of monounsaturated fats, vitamin E, and polyphenols, which are plant-based compounds that have been shown to protect the body from various health issues such as type 2 diabetes, heart disease, and certain cancers. Additionally, these compounds aid in digestion and support brain health.
Registered dietitian nutritionist, Melanie Murphy Richter, explains that the unique structure of olive oil allows it to support cognitive functions by promoting proper communication between brain cells and protecting neurons from inflammation and oxidative stress.
While olive oil is a key component of the Mediterranean diet and has been associated with overall wellness, it is important to choose high-quality varieties. Factors to consider when selecting olive oil include the country of origin, harvest date, type of bottle, and the processing method used. Extra-virgin or cold-pressed organic olive oils are recommended for their higher nutritional profile.
Despite recent price spikes in olive oil due to climate-related supply concerns, experts advise against opting for the cheapest varieties, as they may contain processed elements that diminish the oil's health benefits. Overall, consuming olive oil in moderation as part of a balanced diet may offer potential benefits for brain health and overall well-being.
