I've read many times that our dietary intake of cholesterol is really not related to our cholesterol levels. In actuality, it is believed that cholesterol levels in the body relate to genetics, and thus that you have a natural cholesterol "set point." Realtive to the amount of cholesterol in food, this level is very high, and dietary cholesterol--even a lot of it--would only make up a small portion of this. The balance of your cholesterol level is supplied by the body itself, which synthesizes its own.
To illustrate, I will use very hypothetical numbers. Suppose your "set point" is 100,000 units of cholesterol. Even if you took in tons of cholesterol, you might get 10,000 units from your food, to give you an idea of the relative proportions. The balance--90,000--would be supplied by your own body. If true, people who strive to eat a low-cholesterol diet are wasting their time and actually hurting their health. My opinion is that the cholestrol scare of today is the same as the anti-fat craze of the 1980-1990s. People are afriad of cholesterol so they avoid whole eggs and gobble down Corn Flakes instead. It makes no sense.
You know, cholesterol seems to be in high amounts in natural foods: whole eggs, whole milk, animal meat, etc. Those are the foods that mother nature wants us to eat. I'd much rather eat a diet of all natural foods (which includes the above mentioned cholesterol-filled foods as well as vegitables, fruits, nuts, etc.) than a bowl of ultra-refined Honey Nut Cheerios.
It seems to me that dietary cholesterol should not be a concern. However, things like trans fats and poor carbohydrates should be a concern. Avoid hydrogenated oils, skip refined grains, avoid sugar, eat fruits and vegetables, etc.
