Cholesterol seems to be one of those words that’s in everyone’s vocabulary, but many of my clients
are incredibly confused about what cholesterol is, and how it affects
their health. It also happens to be buzzing in the media at the moment,
thanks to a new report from the Dietary Guidelines Advisory Committee, a group of top nutrition researchers who advise the government about what and how Americans should be eating.

If you’re feeling a little perplexed by all this cholesterol talk, here’s a simple breakdown of what you really need to know.

Cholesterol is only found in animal-based foods

There are two types: dietary cholesterol and blood cholesterol. Dietary
cholesterol is the cholesterol found in foods, and only foods of animal
origin contain it, because animals’ bodies naturally produce this waxy,
fat-like substance. So when you eat an animal-based food (think eggs,
dairy, meat, seafood) you’re ingesting cholesterol that an animal’s body
produced. Plant-based foods do not contain any cholesterol, so if you
see a jar of nut butter marked “cholesterol free” know that they didn’t
remove the cholesterol — it just wasn’t there to begin with.

Cholesterol is essential for your health

Even if you ate zero animal foods, you’d still have cholesterol in your
body. That’s because your liver produces cholesterol and it’s needed for
several key functions, including the making of hormones, vitamin D, and
substances that help you digest food. While cholesterol is vital, it
isn’t considered to be an essential nutrient, meaning something you must
obtain from foods, like vitamin C or potassium. That’s because your
body produces all of the cholesterol it needs.

There are “good” and “bad” types of cholesterol in your blood

The two types of blood cholesterol you hear about most often are HDL
(the “good” kind; think happy cholesterol) and LDL (the “bad” kind;
think lousy cholesterol). HDL and LDL are actually carriers of cholesterol
called lipoproteins. HDL is good because it carries cholesterol away
from arteries and back to the liver, where it can be removed from your
body. LDL “the bad type” has the opposite effect. Too much LDL can lead to
a build-up, which clogs and narrows arteries, and creates inflammation.
This chain of events can lead to a sudden rupture, which sends a clot
into the bloodstream, causing a heart attack and/or stroke.

Dietary cholesterol may not impact blood cholesterol as much as previously thought

The old thinking was that consuming dietary cholesterol added to the
cholesterol that your body naturally produces, thus raising the amount
in your blood. This was perceived to be risky, because too much blood
cholesterol has been shown to up the risk of heart disease, the top
killer of both men and women. One often-cited statistic is that every 1%
increase in total blood cholesterol is tied to a 2% increase in the
risk of heart disease.

For many years, the Dietary Guidelines for Americans recommended that
dietary cholesterol should be limited to no more than 300 mg per day.
To put that in perspective, one egg yolk contains about 185 mg, three
ounces of shrimp contains about 130 mg, two ounces of 85% lean ground
beef about 60 mg, and one tablespoon of butter about 30 mg. The brand
new report eliminated this cap, however, because the committee believes that the research shows no substantial relationship between the consumption of dietary cholesterol and blood cholesterol levels. As such, they concluded, “Cholesterol is not a nutrient of concern for overconsumption.”

The new guidelines aren’t carte blanche to other kinds of animal fat

Nearly every media outlet covered the release of the report from the Dietary Guidelines committee, zeroing in on the omission of cholesterol limits — but
that doesn’t mean it’s now healthy to go out and down cheeseburgers and
pepperoni pizzas. The committee is still concerned about the
relationship between blood cholesterol and saturated fat from foods like cheese.

You may have heard about another recent report, which concluded that a
lower intake of saturated fat wasn’t linked to a lower risk of heart
disease. That’s true, but it’s not the whole story, because the risk
really lies in what you replace the saturated fat-laden foods with. When
people curb saturated fat, but eat more carbohydrates, they lower
protective levels of “good” HDL cholesterol, and drive up triglycerides
(a type of blood fat), a combo that may actually up the risk of heart
disease. But numerous studies have shown that replacing foods like
butter and cheese with plant-based fats like almond butter, avocado, and olive oil can help lower heart disease risk.

Bottom line: the number one message from the new Dietary Guidelines report is that we all need to be eating less sugar and processed foods, and more plants, including vegetables, fruits, whole grains, beans and lentils.
So if you have cholesterol from something like eggs, pair them with
other whole, nutrient-rich plant foods, like veggies and avocado,
combined with some fruit, black beans, sweet potato, or quinoa. That’s
good nutrition.
