An international research team has determined that consuming olive oil every day is associated with a reduced risk of death from dementia by about 30 percent. The study confirms the enormous health benefits of the Mediterranean diet. Here’s how much to eat to protect yourself from Alzheimer’s and other forms of dementia.
A new study has determined that consuming a spoonful of olive oil a day can knock down almost of 30 percent the risk of death For dementiawhose most common form is the Alzheimer’s disease. This is yet another research to highlight the significant ones benefits of this delicious food at the center of the Mediterranean dietUNESCO’s oral and intangible heritage of humanity since 2010. The advantages for the Health they are linked to the precious substances contained in olive oil, among which they appear antioxidants capable of reducing the risk of chronic diseases, healthy monounsaturated fats And anti-inflammatory compounds. Now we know that dressing a salad with a spoonful of olive oil could help us “distancing” more than just that high cholesterol, type 2 diabetes, cancer And heart diseasebut also the most harmful consequences of dementiaa set of neurodegenerative pathologies associated with cognitive declinemotor difficulties, orientation, language and memory problems.
An international research team led by American scientists from the TH Chan School of Public Health at Harvard University, who collaborated closely, determined that a spoonful of olive oil can reduce the risk of death from dementia by 28 percent. with colleagues from various institutes. Among those involved are the School of Medicine of Zhejiang University (China), the Faculty of Medical and Health Sciences of the University of Copenhagen (Denmark), the Department of Medicine of the Brigham and Women’s Hospital (United States) and others. The researchers, coordinated by Professor Anne-Julie Tessier, professor at the Department of Nutrition at the University of Massachusetts, reached their conclusions after conducting a prospective cohort study conducted on over 90,000 adults followed for almost 30 years. These are healthcare workers involved in the Nurses’ Health Study and Health Professionals Follow-Up Study research projects who at baseline – i.e. at the start of the research – did not have a history of cancer or cardiovascular disease. More than 65 percent of participants were women, and the average age was 56.
They were administered during the investigation period food questionnaires to verify the consumption of certain foods. Professor Tessie and colleagues focused on olive oil, evaluating the frequency of intake and dividing the participants into groups (never, 4.5 grams per day, 7 grams per day, more than 7 grams per day etc etc). In the thirty years under review they occurred 4,700 deaths related to dementia among participants. Through thestatistic analysis scholars have looked for an association between olive oil consumption and death from dementia. Combining all the data, it emerged that daily consumption of at least 7 grams of olive oil (roughly one tablespoon) was associated with a 28% reduced risk of dementia-related death compared to no or rare consumption. This is regardless of the quality of the diet. The researchers also found that participants homozygous for the apolipoprotein ε4 allele (APOE4) were 5 to 9 times more likely to die from dementia. Recent research has determined that the one linked to the APOE4 genetic variant is a specific form of Alzheimer’s.

But how does olive oil protect against dementia? The authors of the new study explained that this food “may exert anti-inflammatory and neuroprotective effects thanks to its high content of monounsaturated fatty acids and other compounds with antioxidant properties such as vitamin E and polyphenols.” It is specified that a previous study on the Mediterranean diet had determined that the greater consumption of olive oil was more effective in protecting against cognitive decline. “In addition to heart health, the findings extend current dietary recommendations on the choice of olive oil and other vegetable oils for cognitive health,” Professor Tessier and colleagues noted in the study abstract. Details of the research “Consumption of Olive Oil and Diet Quality and Risk of Dementia-Related Death” were published in JAMA Network Open.
