Matt Metzgar and is Butter bad?

Matt Metzgar has been writing about added oils, butter and fatty acids on his website and concludes that butter consumption is either neutral or harmful to health. Broadly, he argues that a high ratio of saturated to unsaturated fat leads to increased risk for CVD via decreases in flow-mediated dilation (I think).

Butter is not magic Why butter is bad Why butter is bad part ii More on unsaturated versus saturated fat

Chris Kresser dismissed his criticism of butter on twitter outright but I'm wondering what Paleohacks thinks. Is there any substance? I have noticed a trend against added fats in general in the Paleosphere of recent noting Mat Lalonde's diet is entirely free of added fats (and quite low fat generally).

Seems to be a rather myopic view of things.

Most of the questions you're asking our available in the study if you read it. Some info about lifestyle in subjects section. Macronutrient composition of the entire diet in table 2. 2 males and 1 female were smokers in the study, when excluded the results didn't change. Butter was described as "regular".

I quickly read his "Why Butter is Bad - Part 1" post.

If I am not mistaken, all he did was look at this study that correlated "that consuming butter everyday for 3 weeks led to lower flow-mediated dilation." IDK, were the lifestyles of the participants looked at too? What else did these people eat? Any smokers vs non-smokers? Was the Butter grass-fed and raw or was it form some industrial-dump-of-a-dairy-farm, in which the product is full of hormones, chemicals, and anti-biotics?

I'm not too worried. Get a clean source of cream/butter, clarify it, and you've got pure, delicious milk-fat that's full of CLA.

Yeah, I had lots of questions about this, especially since I didn't see anything about pastured butter.
