Even if you think you know everything there is to know about cholesterol, there may be a few more surprises in store. Check out these common myths about high cholesterol; find out who’s most likely to have it, what types of food can cause it, and why—sometimes—cholesterol isn’t a bad word.
Americans have the highest cholesterol in the world
As a nation, we could certainly use some slimming down, but when it comes to cholesterol levels we are solidly middle-of-the-road.
Eggs are evil
It's true that eggs have a lot of dietary cholesterol—upwards of 200 mg, which is more than two-thirds of the American Heart Association's recommended limit of 300 mg a day. But dietary cholesterol isn't nearly as dangerous as was once thought. Only some of the cholesterol in food ends up as cholesterol in your bloodstream, and if your dietary cholesterol intake rises, your body compensates by producing less cholesterol of its own.
Kids can't have high cholesterol
Research has shown that atherosclerosis—the narrowing of the arteries that leads to heart attacks—can start as early as age eight. The American Academy of Pediatrics guidelines on kids and cholesterol recommended that children who are overweight, have hypertension, or have a family history of heart disease have their cholesterol tested as young as two.
Food is heart-healthy if it says "0 mg cholesterol"
The Cholesterol portion of the nutritional label refers to dietary cholesterol, which is only one of the things found in food that can cause your cholesterol to go sky-high. (A bigger contributor to elevated cholesterol? A high-fat diet.) It's also believed to be the least important. Saturated fat (found in animal foods and dairy products) and trans fats (found in packaged foods) appear to have a far greater impact on low-density lipoprotein (LDL), the so-called bad cholesterol that causes atherosclerosis, than dietary cholesterol.
Cholesterol is always a bad thing
When most people hear "cholesterol" they think "bad." The reality is more complex. High cholesterol can be dangerous, but cholesterol itself is essential to various bodily processes, from insulating nerve cells in the brain to providing structure for cell membranes.
