Where to start? First of all, there's no evidence that saturated fat has any bearing on cholesterol levels. The factors which most affect cholesterol transport in the blood are genetics, levels of inflammation, insulin sensitivity and liver function. And as TepidCoffee mentioned above, it's questionable whether cholesterol lowering is beneficial.
Then there's the fatty acid composition of fats. Saturated fatty acids are the most stable, unsaturated less stable and polyunsaturated the least stable. These fatty acids are damaged by exposure to heat, light or oxygen. They should only be consumed in their natural states, as processing damages them and it's damaged fats which contribute to cell membrane damage. This means that there's nothing wrong with vegetable oils as long as you consume them in the vegetable! For example, sunflower oil. Fantastic if you're munching on raw sunflower seeds. But I would never buy or use anything containing sunflower oil, as in order to extract the oil from the seeds heat, light and oxygen will all cause damage to the unsaturated fatty acids present in the oil.
And then, briefly, there's the issue of omega 6 overconsumption. Vegetable oils are disproportionately high in omega 6, overconsumption of which increases inflammation, cell membrane damage, and ironically, inability to metabolise cholesterol.
I also second reading Gary Taubes. The Diet Delusion is like the bible of fats.
