The Mayo recommends limiting saturated fats [1]. So does the American Heart Association [2]. Also the World Health Organization [3]. According to Wikipedia (I haven't checked the links here), Health Canada, the US Department of Health and Human Services, the UK Food Standards Agency, the Food and Drugs Board of Ghana, and 6 other national agencies recommend consuming less saturated fats [4]. I Googled a little bit for articles challenging this consensus, the most scientific seemed be [5]. It cites studies that show no negative effects of saturated fats. However, the only evidence for a positive impact is cross-country comparisons, which have many uncontrolled variables, and mechanistic explanations without epidemiological backing. So, the argument against saturated fats is not unanimous, but I think it's fair to say that it's a consensus. As for a healthy diet being low in unprocessed grains, we'll have to leave that for another day.
