Cholesterol Quiz
• Only adults need to have their cholesterol checked.
Children can’t have high cholesterol?
• All I really need to know about my cholesterol
levels is my total blood cholesterol number?
• If I have high cholesterol the only thing I can do
about it is take medication?
• High cholesterol levels put me at risk for
atherosclerosis?
• Thin people don’t have to worry about high
cholesterol?
Cholesterol
• Approximately 1 in every 6 adults—16.3% of the
U.S. adult population—has high total cholesterol.
The level defined as high total cholesterol is 240
mg/dL and above.
• People with high total cholesterol have
approximately twice the risk of heart disease as
people with optimal levels. A desirable level is
lower than 200 mg/dL.
• For adult Americans, the average level is about
200 mg/dL, which is borderline high risk.
• More women than men have high cholesterol in
the United States.
Cardiovascular Disease (CVD)
• CVD has been the leading cause of death in the
United States for every year since 1900, except 1918
– More than 71 million Americans have at least one form of
CVD (e.g., hypertension, CHD, stroke, or congestive heart
failure)
• Includes deaths from CHD and stroke
– Atherosclerosis most common cause of CHD
• One third of deaths occur before age 65
– Prevalence doubles from 35-44 years to 65-74 years
• Risk reduction; major breakthroughs in prevention
and treatment
Natural Progression of Atherosclerosis
Blood Markers for CHD
• Lipoprotein profile
– Total cholesterol >200 mg/dl
– LDL cholesterol >130 mg/dl
– HDL cholesterol <40 mg/dl
– Triglycerides >150 mg/dl
Lifestyle Risk Factors
• Tobacco use – influences acute coronary events
(thrombus formation, plaque instability and
arrhythmias)
• Physical inactivity – same risk as high blood
cholesterol, HTN or smoking
• Poor diet
• Stress – type A personality shows increased risk
• Alcohol consumption – above moderate
consumption raises BP, TG and HDL
AHA Diet Recommendations for CVD Risk Reduction
• Balance calorie intake and physical activity to achieve or maintain a
healthy body weight.
• Consume a diet rich in vegetables and fruits.
• Choose whole grain, high-fiber foods.
• Consume fish, especially oily fish, at least twice a week.
• Limit intake of saturated fat to <7% of energy, trans-fat to <1% of
energy, and cholesterol to <300 mg/day by:
– Choosing lean meats and vegetable alternatives.
– Selecting fat-free (skim), 1%-fat, and low-fat dairy products.
– Minimizing intake of partially hydrogenated fats.
• Minimize your intake of beverages and foods with added sugars.
• Choose and prepare foods with little or no salt.
• When consuming alcohol, do so in moderation.
• When eating food that is prepared outside of the home, follow the
American Heart Association Diet and Lifestyle Recommendations.

Dietary Factors
• Saturated fatty acids – most potent effect on LDL
chol
• Monounsaturated fatty acids – when used to
replace SFA they lower total chol, LDL & TG; may
increase HDL
• Trans fatty acids – raise LDL chol
• Polyunsaturated fatty acids - when used to replace
SFA they lower LDL & HDL
• Omega-3 fatty acids – decreased CVD risk with fatty
fish 2 times/week
• Amount of dietary fat – low fat diets (<25% of kcals)
raise TG and lower HDL
Dietary Factors–cont’d
• Dietary cholesterol – raise total chol and LDL
• Fiber – soluble fibers (pectins, gums, mucilages)
lower LDL
• Antioxidants – affect oxidative potential of LDL
• Soy protein – large intakes of soy may decrease LDL
• Stanols and sterols – lower total chol and LDL
• Weight loss - improves endothelial function
