Vegetable vs Animal oils
That's more like two questions in one.
Paleo followers generally suggest that animal oils should replace vegetable oils in the diet.
As for the reasons, as I currently understand them:
Did I miss much here? What are other reasons to avoid vegetable oils?
Now, let's assume I have 'virgin olive oil' which is supposedly extracted via cold pressing. Would it be ok to use it in cold dishes like salads etc., avoiding the high temperatures?
