10 Things You Didn't Know About Cholesterol
By Madeline Vann, MPH | Medically reviewed by Niya Jones, MD, MPH
Do you live in fear of cholesterol? You might be surprised to know how essential cholesterol is to the body — you probably couldn't think or have sex without it.
While high cholesterol is a growing health risk among Americans, cholesterol itself gets a bad rap. Our bodies actually make cholesterol and need it to produce cell membranes and sex hormones like estrogen and testosterone. But if the body produces too much cholesterol, it can be a serious risk for heart disease. There may be a lot you don’t know about cholesterol. Read on to smarten up.
10 Fast Facts About Cholesterol
1. Your body has a built-in cholesterol factory. It’s called your liver. The human body needs cholesterol to function properly, but your liver can make all the cholesterol you need, even if you consume no dietary cholesterol at all. Problems start when you eat too much saturated fat and your body makes too much of the LDL, or “bad,” cholesterol, which can then turn into the plaque that lines (and eventually clogs) your arteries. “The body turns over more cholesterol than you eat,” said cardiologist Gerald Berenson, MD, a clinical professor of medicine in the cardiology section at the Tulane University School of Medicine in New Orleans. “When it can’t be handled properly, then it does damage.”
2. Cholesterol fuels your sex drive. That’s no myth — you have cholesterol to thank for making the sex hormones testosterone, estrogen, and progesterone. You wouldn’t want to live without it! In fact, you couldn’t live without it, as cholesterol is also a vital component of cell membranes — think of it as one of your body’s building blocks — and it also plays a role in digestion by helping your liver make the acids needed to digest fat.
3. Pregnant women have naturally high cholesterol levels. During pregnancy, a woman’s total cholesterol and LDL cholesterol reach high levels. This is an important part of making a baby, so it’s not a concern unless cholesterol remains high after giving birth, said Marla Mendelson, MD, medical director of the Center for Women's Cardiovascular Health at Northwestern Memorial Hospital in Chicago. According to research published in the Journal of Brain Development comparing imaging tests of babies born early to those born on time, the good form of cholesterol, HDL or high-density lipoprotein, appears to play a leading role in helping babies form healthy brains. Other research shows that breast milk, which is naturally rich in cholesterol, may offer heart health security later in life. Studies have found that breastfed babies may have lower cholesterol levels as adults, reducing the risk of cardiovascular disease.
4. Infant formula has added cholesterol. To better mimic breast milk, baby formula includes a variety of vitamins, minerals, and, yes, fats, some of which contain cholesterol. Some studies, however, show that the more important additions to formula are the fatty acids in breast milk, like DHA. However, there are currently no government guidelines for how much should be added.
5. Children can have high cholesterol. If you thought high cholesterol could only be a problem for middle-aged adults, you’re wrong. Even children’s cholesterol can reach unhealthy levels. The American Academy of Pediatrics now recommends cholesterol screening at about 9 years of age for all children. “What is hard to believe is that people have heart disease risk factors in childhood — 40 years before they have a heart attack,” noted Dr. Berenson, principal investigator of the Bogalusa Heart Study, a community-based study that has tracked the development of heart disease risk factors from elementary school years into middle adulthood.
Along with a healthy diet, proper weight, and exercise, children who have a family history of early fatal heart attacks (meaning before age 40) may benefit from cholesterol and blood pressure medication to appropriately manage high cholesterol and other risk factors, Berenson says.
6. The average American has a cholesterol level that’s already borderline high. According to the U.S. Centers of Disease Control and Prevention (CDC), the average cholesterol level among adult Americans is 200 mg/dL, considered borderline high by the by the American Heart Association (AHA). It’s an alarming statistic, but the idea that everyone should strive for the same number is a cholesterol myth. Everyone is different, so talk so to your doctor about setting your goal cholesterol levels.
The 2013 cholesterol guidelines from the AHA recommend statin therapy — a medication that lowers cholesterol levels in the blood — for 4 groups of people:
Patients who have heart disease
Patients who have LDL cholesterol levels at 190 mg/dL or higher
Patients who are between 40 and 75 years old and have type 2 diabetes
And people between ages 40 and 75 who have a high risk of heart disease
7. You can see cholesterol in your eyes. White rims around the cornea of the eyes are a sign of cholesterol buildup, though they don’t necessarily indicate a heart problem. However, visible fatty lumps of cholesterol under the skin on the eyelids (known as xanthelasma) may predict future heart issues, according to a study published in the British journal BMJ. Researchers looked at 12,745 adults in Denmark and found a strong link between these lumps and heart disease or a heart attack five years later.
8. Cholesterol looks a lot like fat. Though we tend to think of high blood cholesterol as just a number from a blood test, Berenson said that when cholesterol lines your arteries, these deposits tend to be yellow with a white covering, much like fat.
9. Cholesterol may protect your skin. Early skin treatment research indicates that cholesterol added as an ingredient in moisturizers could help protect skin from UV damage. Other lipid, or fatty, ingredients don't provide the same protection, according to research published in the Journal of Dermatological Science.
10. One of your friends needs a cholesterol check. The National Cholesterol Education Program recommends cholesterol screenings every five years after age 20. About one in four people have never had a cholesterol check. Chances are one of your friends, or you, needs to schedule one.
