　　Canola oil (canola oil) is squeezed from the rapeseed of a Brassica plant. Compared with ordinary rapeseed oil, the level of erucic acid in canola oil is less than 2%, the level of glucosinolates is less than 30 micromolar, and the content of unsaturated fatty acids that are beneficial to health is higher, so it is promoted as "double "Low and high" healthy oil.

　　However, scientific research has questioned this! On December 7, a study published online in the journal Scientific Reports revealed that canola oil can cause memory loss, decline in learning ability, and weight gain in Alzheimer's disease mice. This study shows for the first time that canola oil can damage the brain and do more harm than good.

　　Damage the brain?

　　"Canola oil is very attractive because it is cheaper than other vegetable oils and it is advertised as good for health." Domenico, director of the Alzheimer's Research Center and Professor of Medicine and Microbiology at Temple University Lewis Katz School of Medicine (LKSOM) Praticò said, "However, very few studies have confirmed this claim, especially for the effects on the brain."

　　Professor Domenico Praticò led the laboratory doctoral student Elisabetta Lauretti to study the effects of canola oil on memory, amyloid plaques and neurofibrillary tangles (typical pathological features of AD) using mice with Alzheimer’s disease (AD) as a model The impact of formation.

　　They used the same animal model to study olive oil, and found that feeding Alzheimer's mice with food rich in extra virgin olive oil can reduce amyloid plaques, phosphorylate the level of Tau protein, and improve memory.
