Incorrect.
Whilst the body might not be able to differentiate, between different Fat sources, I.E you eat some cake then some Flaxseeds, the body is not capable of recognising them as such, exept for your senses like Eyes, Brain, which see and process what you see. You know what you've eaten in that case, as your eyes see the Cake and Flaxseeds, your brain translates that information, and makes you aware in your mind, they are what they are.
The bodies digestive system doesn't react to what those things are, it only really reacts to what's in them, and the weight / molecular density of the food, and even though Flaxseed Fats, and Saturated Cake Fats, are both 9 calories per gram, they are not the same, and have different physiological effects, so having Fats from Cake sources which often contain provessed Flour, saturates, and some Egg Yolk Cholesterol, does have an impact.
Even if you ate 1g of Sature it would almsot certainly store, compared to 1g of Omega Fats, or another healthy Fat source. Whilst 1g of Saturate is not crime of the century, and possibly a tiny amount of Saturate is needed per day, the 1g of something like Omega, will create a different Physiological reaction, because it probably has a different molecular shape, structure, density etc etc, and perhaps different atoms, or configuration / number of atoms.
You could also argue the case, that someone who eat 3,000 cals a day, 2% of which were Saturates, would be better off than someone who ate 2,000 a day, 50% of which were Saturates, making sure of course healthy food is kept to acceptable portions sizes, as excess calories convert to fats, even if they come from things like Egg Whites, Broccoli, Tomato etc etc
