Review: Dietary saturated fats have an undeserved bad reputation
The comments in the (mostly cardiologists) discussion at the bottom is very interesting:
Rockville, MD - "The influence of dietary fats on serum cholesterol has been overstated," concludes a review in an American Society for Nutrition publication that, in its words, "calls for a rational reevaluation of existing dietary recommendations that focus on minimizing dietary [saturated fatty acids] SFAs, for which mechanisms for adverse health effects are lacking" .
Indeed, argues the author, Dr Glen D Lawrence (Long Island University, Brooklyn, NY), it is likely other factors, such as oxidized polyunsaturated fatty acids (PUFAs) or preservatives in processed meats, that are also present in high-SFA foods that lead to adverse health effects typically associated with high SFA intake.
"The meager effect that saturated fats have on serum cholesterol levels when modest but adequate amounts of polyunsaturated oils are included in the diet, and the lack of any clear evidence that saturated fats are promoting any of the conditions that can be attributed to PUFA, makes one wonder how saturated fats got such a bad reputation in the health literature," Lawrence writes in the review, published May 1, 2013 in Advances in Nutrition."

Before believing any opinion, even an informed one, it's best to check what the other medical literature is saying.
Here's a link to the National Library of Medicine -- called PubMed -- where you can read the research on the same topic:
re: maria lorraine
I find all my sources on PubMed, as a rule and, I've been reading just about every publication on the topic going decades back.
Gary Taubes has written superb and objective reviews of the science, and his expertise and objectivity in evaluating crap science has come in very handy. His articles, like "The Soft Science of Dietary Fat and "What if Dr. Atkins is Right?." It's so refreshing to have someone with objectivity and a keenly analytical eye do the assiduously researched and exhaustive review like "Good Calories, Bad Calories."
I'd worry a lot more about all fats from feedlot animals and other polluted sources than healthy saturated fats.

This is from the abstract:
"The evidence of ω6 polyunsaturated fatty acids (PUFAs) promoting inflammation and augmenting many diseases continues to grow, whereas ω3 PUFAs seem to counter these adverse effects.
"The replacement of saturated fats in the diet with carbohydrates, especially sugars, has resulted in increased obesity and its associated health complications.
"Well-established mechanisms have been proposed for the adverse health effects of some alternative or replacement nutrients, such as simple carbohydrates and PUFAs.
"The focus on dietary manipulation of serum cholesterol may be moot in view of numerous other factors that increase the risk of heart disease. The adverse health effects that have been associated with saturated fats in the past are most likely due to factors other than SFAs."
