Lamb rump, yolks, beef suet, chicken skin, bacon… Delectable animal foods, all nourishing, and all significant sources of saturated fat. The main premise behind the strong suggestion to “limit one’s intake of meat” is to reduce one’s consumption of saturated fat. According to the American Heart Association’s (AHA) “presidential advisory”, we’ll find great cardiovascular benefits if we replace saturated fat in our diet with polyunsaturated fats . In other words, replace nourishing animal foods with a plethora of nuts, seeds… even seed oils, if we choose. The suggestion to reduce or nearly eliminate saturated fats from our diet is unnatural, yes, and worse, quite shady, for 2 reasons: 1. Contradictory evidence was dismissed. There are two large meta-analyses [2-3] that show no significant association between saturated fat intake and cardiovascular health. 2. The AHA cherry picked 4 “core’ studies [4-7]. 2 of which showed no statistical difference between saturated and unsaturated [4-5]. The 2 that did show statistical differences have been consistently criticized. In , the experimental population changed over time 🤯 In , the relative risk of saturated vs unsaturated was 1.19, which corresponds to odds of 54:46. Not very significant. There’s no surprise that the presidential advisory report was created by members of the AHA, reviewed by an AHA committee, and published in ‘Circulation’, a journal published by AHA.
We’re taught to fear saturated fat and welcome ‘heart healthy’ grains and cereals, loaded with anti-nutrients & even more sugars. Perhaps the health issues we find prevalent today stem from what else we’re eating, not animal foods our ancestors have been eating for centuries, much before the rise of chronic disease.
