Arthur T Knackerbracket has found the following story:

Canola oil is one of the most widely consumed vegetable oils in the world, yet surprisingly little is known about its effects on health. Now, a new study published online December 7 in the journal Scientific Reports by researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) associates the consumption of canola oil in the diet with worsened memory, worsened learning ability and weight gain in mice which model Alzheimer's disease. The study is the first to suggest that canola oil is more harmful than healthful for the brain.

"Canola oil is appealing because it is less expensive than other vegetable oils, and it is advertised as being healthy," explained Domenico Praticò, MD, Professor in the Departments of Pharmacology and Microbiology and Director of the Alzheimer's Center at LKSOM, as well as senior investigator on the study. "Very few studies, however, have examined that claim, especially in terms of the brain."

Curious about how canola oil affects brain function, Dr. Praticò and Elisabetta Lauretti, a graduate student in Dr. Pratico's laboratory at LKSOM and co-author on the new study, focused their work on memory impairment and the formation of amyloid plaques and neurofibrillary tangles in an Alzheimer's disease mouse model. Amyloid plaques and phosphorylated tau, which is responsible for the formation of tau neurofibrillary tangles, contribute to neuronal dysfunction and degeneration and memory loss in Alzheimer's disease. The animal model was designed to recapitulate Alzheimer's in humans, progressing from an asymptomatic phase in early life to full-blown disease in aged animals.

Dr. Praticò and Lauretti had previously used the same mouse model in an investigation of olive oil, the results of which were published earlier in 2017. In that study, they found that Alzheimer mice fed a diet enriched with extra-virgin olive oil had reduced levels of amyloid plaques and phosphorylated tau and experienced memory improvement. For their latest work, they wanted to determine whether canola oil is similarly beneficial for the brain.

    Canola is the number two Frankenstein crop, perhaps only surpassed by wheat. The pretext is that nothing is done that nature doesn't do anyway. The reality is that nature does it very slowly and the surrounding ecosystem can adapt in turn. We are eating stuff that we may yet need to adapt to, and we have no idea how many generation it would take - that is if we are willing for any unsuitable offspring's to die of those crop to be properly 'selected' in order to be compatible.

    First re-purposed from lubricant for steam engines, to a diesel replacement and than heavily modified genetically to be edible, it is also a field experiment on humans by Monsanto to explore effects of GMO's on humans and to test their capacity to dominate and take away food production by independent farmers, sometimes under the pretext of rising food prices (a problem which they are part of).
