When you accept that the LDL/lipid hypothesis is wrong, the fact that saturated fat consumption is healthy and evolutionarily consistent, and polyunsaturated fat (predominantly linoleic acid) excess is causing chronic disease being to make a whole lot more sense.
For decades we have been told that vegetable oils are "heart-healthy" because they lower LDL, but once we realize that LDL is not the villain in heart disease these recommendations begin to look extremely suspect, and even harmful for us.
Furthermore, data regarding increases in oxLDL and Lp(a) with increased polyunsaturated and decreased saturated fat have largely been ignored because they don't fit the prevailing narrative.
The large amount of interventional data comparing higher saturated fat to higher polyunsaturated fat (PUFA) diets (Minnesota Coronary Study, Sydney Diet Heart, etc.) showing the dangers of PUFA has also been ignored for this same reason.
The very real and tragic fact of the matter is that the mainstream advice to consume vegetable oils over animal fats for the last 70 years has resulted in millions of deaths, yet the AHA will never have to answer for this. Time for this paradigm to be challenged and to change.
