A short conversational YouTube transcript (Ben Greenfield) arguing that for diets to be widely adopted, health foods must taste good and be satisfying; otherwise most people will not maintain restrictive diets. The transcript also critiques the common claim that polyunsaturated fatty acids (PUFAs)/seed oils are heart-healthy, stating that while they lower LDL cholesterol, they promote LDL oxidation and foam cell formation leading to plaque.
One of the hard sells about diets in general to people, whether it's keto or gluten free or carnivore or vegan or whatever, is that the diet doesn't taste good. You know, you have to have extreme amounts of willpower and some amount of, you know, masochism almost in order to maintain yourself in some diet that's unpleasant. Some people can do it, most people won't do it. And so if we want the mass of people to be healthy, their health foods have to also actually taste good and satisfy them.
So when people say things like PUFAs are heart healthy, are they totally off base or are there shreds of truth to where that's coming from? That claim is generally shared because what happens is when you consume these fatty acids, your LDL cholesterol goes down. What's not shared is that your LDL cholesterol gets oxidized, eaten up by like, gives the signal into macrophages, turns into foam cells, and gets deposited in your endothelium as plaque. So that's why your LDL goes down while eating seed oils.
