I used canola oil for years, and soy oil, corn oil, and other manufactured oils. Then I read on the westonaprice.org website information with solid scientific documentation from sources like The Lancet, and now I read labels to ensure Im not eating any of those oils.
There are two huge problems with these manufactured oils, of which canola is the worst: in the high pressure and heat of processing, the oils are denatured, turn rancid, and develop all kinds of free radicals. Most of us know of the dangers of free radicals. The other problem is that they have none of the health benefits of traditional oils like ghee, coconut and palm oil, and animal fats. Traditional fats contain vitamins, enzymes that our bodies need, and other factors. For example, the lauric acid in coconut oil was reported by a study done by the United States Center for Disease Control to destroy the lipid coating of 27 different classes of viruses, including influenza, rhinovirus, and varicella (chickenpox and shingles).
And contrary to proper belief, many studies have documented that the heart and kidneys run on saturated fat, and without saturated fat cell membranes become weak.
Really, our ancestors knew what worked. Since Ive returned to eating a more traditional diet that doesnt include many, if any, Western foods, I and my family are much healthier--I and my children have not been sick in two years.
And traditional foods taste better. I cant stand the taste of canola.
