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 whos most likely to have it, what types of food can cause
it, and why—sometimes—cholesterol isnt a bad word.
Myth 1: Americans have the highest cholesterol in the world
Myth 1: Americans have the highest cholesterol in the world
One
of the world's enduring stereotypes is the fat American with cholesterol-clogged
arteries who is a Big Mac or two away from a heart attack. As a nation, we
could certainly use some slimming down, but when it comes to cholesterol levels
we are solidly middle-of-the-road.
According
to 2005 World Health Organization statistics, American men rank 83rd in the
world in average total cholesterol, and American women rank 81st; in both
cases, the average number is 197 mg/dL, just below the Borderline-High Risk
category. That is very respectable compared to the top-ranked countries: In
Colombia the average cholesterol among men is a dangerous 244, while the women
in Israel, Libya, Norway, and Uruguay are locked in a four-way tie at 232.
Myth 2: Eggs are evil
Myth 2: 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.
While you don't want to overdo it, eating an egg or two a few times a week isn't dangerous. In fact, eggs are an excellent source of protein and contain unsaturated fat, a so-called good fat.
Myth 3: Kids can't have high cholesterol

Myth 3: Kids can't have high cholesterol
Most
people think high cholesterol is a problem that's strictly for the middle-aged.
But guess what? Research has shown that atherosclerosis—the narrowing of the
arteries that leads to heart attacks—can start as early as age eight. In July
2008, the American Academy of Pediatrics released guidelines on kids and
cholesterol that recommended that children who are overweight, have
hypertension, or have a family history of heart disease have their cholesterol
tested as young as two years of age.
Children with high cholesterol should be on a diet that restricts saturated fat to 7% of calories and no more than 200 mg per day of dietary cholesterol, according to the guidelines. Fiber supplements and more exercise are also recommended.
While the guidelines prompted a bit of an outcry from parents worried that doctors would be pushing cholesterol-lowering drugs for kids, a new study suggests that less than 1% of adolescents aged 12 to 17 would be considered candidates for medication.
Myth 4: Food is heart-healthy if it says "0 mg cholesterol"

Myth 4: 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.
Myth 5: Cholesterol is always a bad thing
Myth 5: Cholesterol is always a bad thing
When
most people hear "cholesterol" they think "bad." Like most
things in life, 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.
That's why your body makes the white, waxy substance (about 75% of the
cholesterol in your blood is made by the liver and cells elsewhere in your
body).
The role of cholesterol in heart disease is often misunderstood. Cholesterol is carried through the bloodstream by low-density and high-density lipoproteins (LDL and HDL). LDL, known as bad cholesterol, and not the cholesterol it carries per se, is responsible for atherosclerosis.
