15. Linked fact checks
- Natural fats such as baladi ghee and butter are not a cause of clogged arteries (contrary to the previously dominant view); 'good fats do not stick'. – Studies contradicting or limiting the claim
- Olive oil is an allowed fat in the system. – Studies supporting the claim
- Olive oil (and flaxseed oil) should be avoided because it is adulterated ('it is all fake') and has a problem with its acidity; instead a little corn oil and sunflower oil should be used for frying. – Studies with mixed or unclear results
