Go get the current issue of Tine Magazine[1]. This thinking was never backed up with good science 40 years ago and has been totally debunked in literature in the last decade. Saturated fat is very much a part of a healthy diet.

1. No, I don't consider that the "literature", but it's a good jumping off point to start learning what is true in nutrition versus what is dogma.

Dietary Fat is not bad for you, neither is it the same thing as body fat which is an indicator for excessive energy intake (most often from sugary drinks) and being generally misinformed (99% Fat Free? Awesome! Nevermind that added sugar to cover the lack to flavour we took out). What is bad for you is too much, EXCESS. Except this goes for everything. Such as too much sugar, protein, hormones, almost any drug & water can be a detriment, even lethal to you. I'll only give you that trans-fat is terrible.

The market hasn't and never will teach you that moderation is healthy because it's against their business model of selling excess. See meal portion sizes and how they have increased over the last few decades. I hope you're not taking fish oil supplements as well. Anything with this much marketing behind it should be cautioned with much skepticism.

Edit: I stand behind my criticism of anti-fat culture.

There is no evidence Saturated fat is bad.
