Lipids are naturally occurring organic compounds that are often associated with raising blood cholesterol, specifically fats, according Michigan State University's Department of Chemistry. There are several types of lipids that contribute to unhealthy cholesterol levels, which leads to health complications like coronary and heart disease. MayoClinic.com recommends routine blood tests to monitor cholesterol, since high levels do not have any symptoms.
Low-density Lipoprotein
There are two forms of cholesterol within the body, high-density lipoprotein and low-density lipoprotein. Low-density lipoprotein is the "bad" cholesterol. LDL is the main source of damaging buildup within the arterial walls, according to the National Heart, Lung and Blood Institute. The more LDL you have in your blood, the higher your risk of heart disease. Generally, LDL levels exceeding 100 mg/dL indicate high blood cholesterol, the National Heart, Lung and Blood Institute says.
Triglycerides
Triglycerides are fat lipids carried throughout the bloodstream after procurement through diet, according to Paul Insel in the book "Nutrition." It consists of three fatty acids attached to a glycerol molecule. Although triglyceride provides a major source of energy to the human body, it is also a main contributing factor in high cholesterol, according to Adrianne Hardman and David Stensel in the book "Physical Activity and Health."
Foods to Avoid
If you are at risk of heart disease and high blood cholesterol, avoiding certain foods is essential in safeguarding your health. Processed meats, such as deli meats, salami and hot dogs, contain an inordinate amount of saturated fat, which is the leading cause of LDL cholesterol, according to the U.S. Department of Health and Human Services. Hydrogenated and partially hydrogenated oils not only raise LDL levels but also lower HDL levels, effectively clogging your arteries, MayoClinic.com says. Avoiding stick margarine, pastries, fast food and commercial baked goods will reduce trans-fat consumption.
