Saturday March 17, 2012 (foodconsumer.org) -- A new Japanese study published in 2010 in Toxicology suggests that eating canola oil may cause damage to the heart and the  kidney.

Y. Naito of Hatano Research Institute Food and Drug Safety Center in Japan and colleagues found spontaneously hypertensive rats and Wistar Kyoto rats fed a diet with 10% canola oil also known as rapeseed oil for 10 weeks had much higher systolic blood pressure, compared to rats fed soybean oil.

At 26 weeks of the feeding regimen, the researchers found "in the canola oil group the heart and kidney tended to become heavier with sporadically found histologic lesions."

They also found that "the 26-week feeding of canola oil increased plasma lipids and the neutrophil counts, and decreased the platelet counts."  

Canola oil is made from genetically modified rapeseed and used in a wide range of processed foods. It is also used as a cooking oil.
