nowadays, it's actually high school biology to understand that you're really not what you eat. your body takes everything you eat, breaks it down into small carbon chains and then puts it back together again. blood cholesterol levels are consequently controlled by your liver, not your diet.
an easy understanding is this:
energy consumed - energy burned = energy stored.
if your body is storing too much energy, be it in cholesterol or some other way, what it means is that this equation is not balancing - which in practical terms usually means that not enough energy is being burned. so, the answer is to get the cardio up.
