Most people equate eating a diet low in cholesterol as a means to lower serum cholesterol levels. However consuming a diet high or low in cholesterol doesn't make as big of a difference in serum cholesterol as once believed.
Nutritional science has come a long way in the last 10 years.
We now know that a diet limiting refined carbohydrates such as bread and cereals is just as effective, if not more effective at lower cholesterol than cutting out fats.
The bottom line is cutting calories lowers serum lipids. It's that simple, but cutting calories is very unpopular. People don't want to hear that.
Lower cholesterol is associated with lower risk for heart attack and stroke in the minds of consumers, however half the heart attacks happen to people with low cholesterol. In the real world, the connection between cholesterol levels and risk for heart disease is foggy at best. But sales and marketing tells us otherwise.
