“Cardiovascular disease (CVD) is the leading global cause of death, accounting for 17.3 million deaths per year.” -Presidential Advisory From the American Heart Association, 2017
Claim 1 – “lowering intake of saturated fat and replacing it with unsaturated fats, especially polyunsaturated fats, will lower the incidence of CVD. “
Suggests DASH (Dietary Approaches to Stop Hypertension) and Mediterarian diet, leaning heavily on grains, vegetable oil, soy, etc. (more on this later).
Why This Claim is Important: It is a strong, academic representation of the establishment position of one of the most culturally dominant nations on Earth, the American Heart Associations Presidential Recommendation, the official summary of decades of official health advice. It “[takes] into consideration the totality of the scientific evidence, satisfying rigorous criteria for causality.” It is echoed by the likes of :

“But, for now, I’d use coconut oil sparingly. Most of the research so far has consisted of short-term studies to examine its effect on cholesterol levels. We don’t really know how coconut oil affects heart disease. And I don’t think coconut oil is as healthful as vegetable oils like olive oil and soybean oil, which are mainly unsaturated fat and therefore both lower LDL and increase HDL. Coconut oil’s special HDL-boosting effect may make it “less bad” than the high saturated fat content would indicate, but it’s still probably not the best choice among the many available oils to reduce the risk of heart disease.”

Claim 2 – “Every 30 point reduction in cholesterol came with a 22% increase in mortality. You read that right. The very data used by the AHA in their marketing campaign actually shows that lowering cholesterol can kill you. In one of the AHA’s go-to studies, researchers spell out that the low saturated fat, low cholesterol experimental diet might be toxic since they saw a jump in mortality.” – Dave Asprey (see links bellow)
Why This Claim is Important: The AHA consolidated their position on what constitutes the most relevant evidence of causality, and while a lot of (supposedly) better, recent research is claimed by the opposition to have been overlooked, this summary of the very data that the AHA allegedly used against saturated fat, allegedly undermines their own position. It’s sort of a double blow to be able to test a claim that (if correct) would lend weight to the opposition narrative, while so directly refuting the establishment narrative.

Personal Bias: Bulletproof coffee, clean beef, and vegetables seems to work for me. I don’t trust Bulletproof blindly, nor am I in any sort of total agreement, but I think they’re onto something.
