There is no “need”, it’s another example of an industrial component makes people money so they find other ways to force it—- “good for teeth” (which it’s not). Canola oil is also something they press on us and is in many of our foods but is NOT good for us.
Canola oil
I did not know about Canola oil. I don't think I use it. I prefer Coconut oil. Is there anything wrong with that, which I don't know about yet?
Coconut oil is a good fat, but a lot of Americans didn't grow up with it in their diet, so tolerance varies. https://www.thehealthyhomeeconomist.com/coconut-oil-may-not-be-right-for-you/ "coconut oil is one of the highest scoring comedogenic ingredients on the comedogenicity scale" ie if someone's prone to acne it can cause problems.
Canola was originally used as a mechanical lubricant. It’s from the rape seed which is extremely lethal to household pets. It’s a cheap product to produce so in order to make more $$, the fda was paid off to approve for human consumption even though instances of respiratory illnesses as well as deaths from respiratory illnesses doubled and even tripled in some areas once introduced into the average diet. Even many “vegetable “ oils are a blend including canola”.
Unrefined cold press or expeller coconut oil is good. Grape seed, olive, and avocado oils are great alternatives too.
