Canola oil might not be the best choice for the health of your body and brain. A recent study performed on mice revealed that consuming this type of oil might cause you to gain weight, and also contribute to memory decline in Alzheimer’s disease.
Canola oil is advertised as healthy
Canola oil is one of the most widely-used vegetable oils, and is made of rapeseed plant. Many nutritionists regarded it as a healthy dietary choice, and found it better than saturated fats. However, these facts were rather empirical, as researchers lacked any clear evidence of the benefits of the oil. In fact, it is less expensive than other oils, and was advertised as healthy.
Through this study, researchers discovered that canola oil is not that good, and identified some harmful effects it might have on the brain. To test the hypothesis, researchers designed an Alzheimer’s model on mice, and looked at the formation of amyloid plaques on the brain. This contributes to gradual memory loss.
The Alzheimer’s model created on mice closely followed the progression of the disease on a human brain. This wasn’t the first time when they used such a model to determine how good an oil is. In a previous study, they investigated the effects of olive oil, and discovered it reduced the chances of memory loss.
Canola oil accelerated memory loss in Alzheimer’s
To investigate the effects of the oil, they split the mice in two groups. One received a regular diet, while the other received the equivalent of two spoons of canola oil every day. After six months, they noticed how the memory of the second group started declining. One year later, this group had also gained weight.
Researchers looked at the brain of these mice, and discovered how the canola oil reduced the amyloid beta 1-40 deposits. These have a protective effect on the brain, and start degrading at an advanced stage of Alzheimer’s disease. This made the researchers warn people this type of oil might not be that beneficial.
“Based on the evidence from this study, canola oil should not be thought of as being equivalent to oils with proven health benefits.”
