Get Your Fats Straight!

Every week I get dozens of questions like 'what oil should I use for cooking'? 'Should I eat butter or margarine'? 'How much fat should I be eating'? People are just confused about fat and this confusion and misinformation has led to one of the biggest public health cockups in history. This is my take on the problem, and hopefully I can shed a little light on this potentially confusing subject.
