A Recent research has uncovered damage canola oil consumption triggers in your brain and the effect this may have on your memory and learning ability. The study, published in the journal Nature, also found the consumption of canola oil increased weight gain.

The study was led by researcher Dr. Domenico Praticò from Lewis Katz School of Medicine at Temple University in Philadelphia, Pennsylvania. Praticò commented to the Los Angeles Times that canola oil is perceived by many to be healthy — a widespread misconception.

Researchers used an animal model to evaluate the effect canola oil has on the brains of mice genetically engineered to develop Alzheimer’s disease.5 Canola oil developed a reputation of being healthy when doctors began warning people to reduce their saturated fat intake and consume vegetable oils instead. Canola has the lowest percentage of saturated fat of all commonly used vegetable oilsand is relatively inexpensive, but is actually one of the worst oils for your health.

Canola oil is often used in homes and restaurants for baking, sautéing, frying and other forms of cooking, with consumers being deceived into believing it’s better for them than saturated fats. The mice were split into two groups; one group was fed the usual chow and the second group was fed chow with the human equivalent of 2 teaspoons of canola oil per day.

At the end of the experimental six months, researchers observed that the mice eating chow laced with canola oil were significantly heavier than the mice that did not eat canola oil. Additionally, the mice who had eaten canola oil demonstrated significant declines in working memory together with a decreased level of post-synaptic density protein-94, a marker of synaptic integrity. The researchers found canola oil had a negative effect on health.
