Why is saturated fat bad for heart health?

Dr. Michael Roizen, MD
Internal Medicine
No food element has been more closely linked to arterial aging than saturated fats and their cousins, trans fats. This relationship was confirmed by a twenty-five-year study that evaluated the development of coronary heart disease and the long-term risk of death. Studies have repeatedly found a strong correlation between cardiovascular disease and the consumption of saturated fats.

Apparently, saturated and trans fats increase inflammation of the blood vessels. They turn on certain genes that produce proteins associated with inflammation of blood vessels. Foods high in saturated fats promote plaque buildup along the artery wall, which is the first stage of cardiovascular disease and arterial aging. In addition, saturated fats facilitate the mechanism that increases low-density lipoprotein (LDL) cholesterol in the bloodstream.
