Oliver oil may be better for brain health than canola oil, although the latter has been popular since it reached the market in 1970, thanks to its health benefits and affordability.
Temple University of Philadelphia recently studied the impact of vegetable oils on the brain of mice.
Dr. Domenico Praticò and colleagues from the Lewis Katz School of Medicine in Temple fed canola oil and olive oil to mice that were bred to develop Alzheimer's disease.
Said canola-fed mice showed impaired memories, decreased learning ability and weight gain. They also experienced an increase in the level of amyloid plaques in the brain.
The opposite was found when similar mice consumed food with extra virgin olive oil. In an investigation published earlier this year, Praticò and co-author Elisabetta Lauretti discovered that mice with the disease showed improved memory and reduced levels of amyloid plaques.
The cause of Alzheimer's disease is the most common form of dementia. unknown. But researchers believe that the accumulation of beta-amyloid protein, or "plaques," is a major contributing factor.
