To demonstrate that octopus isn't high in cholesterol, let's take a look at how it compares with cholesterol lowering foods high in omega-3 fatty acids.

Compared to cholesterol lowering fish, octopus is relatively low in cholesterol. The omega-3 fatty acid content in octopus may seem subpar compared to omega-3 sources such as pacific jack mackerel and herring. However, in terms of omega-3 and saturated fatty acid content, there is no significant difference. All foods presented above have omega-3 content greater than or equal to saturated fat content indicating a correlation between omega-3 and saturated fatty acid content balance.

Saturated fat cutbacks

Despite the boast about how dietary omega-3 fatty acid lowers cholesterol, studies suggest that it doesn't work without lower intake of saturated fats.
"Many studies show that the effects of omega 3 fatty acids on serum lipids depend on the type of patient and whether the amount of saturated fatty acids in the diet is held constant." - Omega-3 fatty acids and cholesterol
So, what does this mean in terms of your diet? - Let's take a look at the recommended daily intake for saturated fats trans fats and cholesterol to see what we are up against.
As long as you daily cholesterol intake is under 750mg you shouldn't have anything to worry about. Note that this is roughly 1kg of Herring. As you can see, the problem isn't keeping down your cholesterol.

Natural inhibitors of cholesterol

Foods with omega-3 fatty acids act as natural cholesterol inhibitors slowing down the rate in which your cholesterol increases.
"Dietary omega-3 fatty acids lower plasma LDL levels in normal human subjects by reducing the rate of synthesis of apoprotein B."- Inhibition of bad cholesterol
Apolipoprotein B (ApoB) is connected to the transport of bad cholesterol. Mutations of the ApoB gene, a particular type of obesity gene is said to be one hereditary cause of high cholesterol.
Octopus is a prime example of a cholesterol inhibiting food. Not only does it have omega-3 that inhibits the increase of bad cholesterol but also contains taurine.
Taurine is the reason why octopus is a cholesterol lowering food. Taurine has been shown to reduce the secretion of ApoB. - Taurine reduces Apolipoprotein secretion
Omega-3s and taurine inhibit Apolipoprotein B or gene expression of the ApoB gene reducing the transport of bad cholesterol throughout your body, thus helping to lower cholesterol.
