Your Heart Health Story: The Numbers, Tests & Nutrition That Matter Most
Cholesterol is only one piece of your heart-health story.
You get your annual labs back.
You scan the page.
LDL? Check. HDL? Check. Triglycerides? Check.
Then you get the familiar message:
"Everything looks pretty good."
Great! But what if there's more to the story?
Today, we have some pretty incredible tools that can help us understand cardiovascular risk before heart disease announces itself with symptoms.
At RI Nutrition Therapy, we're big believers in prevention. And prevention starts with knowing what your numbers actually mean—and what you can do about them.
So grab your imaginary detective hat.
We're going beyond basic cholesterol.
First Stop: Your Basic Heart-Health Dashboard
Your standard lipid panel is still important.
It usually includes:
LDL cholesterol
Often called "bad" cholesterol, although the biology is a little more complicated than that.
HDL cholesterol
Commonly called "good" cholesterol.
Triglycerides
A type of fat circulating in your bloodstream.
Total cholesterol
A combined measurement of several types of cholesterol.
But here's the important part:
Your cholesterol panel isn't your entire cardiovascular report card.
Depending on your medical history and risk factors, there are other numbers worth discussing with your healthcare provider.
Meet ApoB: The Traffic Counter
Here's an easy way to think about Apolipoprotein B (ApoB).
Imagine your bloodstream is a highway.
LDL cholesterol tells us something about how much cholesterol is being transported.
ApoB gives us information about how many potentially artery-damaging vehicles are on the road.
🚗 🚙 🚕 🚗 🚙 🚕
More vehicles = more opportunities for particles to enter the artery wall and contribute to plaque formation.
That's why two people can have similar LDL cholesterol levels but potentially different cardiovascular risk.
For certain people, ApoB can add useful information beyond the traditional cholesterol panel.
Ask your healthcare provider:
"Would checking my ApoB provide useful information about my cardiovascular risk?"
Lp(a): The Number You May Have Inherited
Next up: Lipoprotein(a), or Lp(a).
This one is particularly interesting because your Lp(a) level is largely determined by genetics.
Translation?
You could eat beautifully, exercise regularly and have a healthy lifestyle—and still have an elevated Lp(a).
That's why knowing your family history matters.
Current cardiovascular guidelines recommend that adults have Lp(a) measured at least once in adulthood.
This may be especially worth discussing if you have a family history of premature heart attack, stroke or cardiovascular disease.
Think of Lp(a) as information—not destiny.
If your Lp(a) is elevated, it doesn't mean you're destined to develop heart disease.
It means you and your healthcare team may want to pay even closer attention to the risk factors you can modify.
hs-CRP: Is There Smoke?
High-sensitivity C-reactive protein (hs-CRP) measures inflammation in the body.
Think of it a little like a smoke detector.
If it goes off, we know something may be creating inflammation—but it doesn't necessarily tell us exactly where the fire is.
Infections, injuries and other medical conditions can raise CRP, so this test needs to be interpreted in context.
But in the right situation, hs-CRP can provide another piece of the cardiovascular-risk puzzle.
Don't Forget Blood Sugar
Heart health and metabolic health are closely connected.
That's why we also pay attention to:
Fasting glucose
Hemoglobin A1c
Blood pressure
Triglycerides
Kidney function
These numbers help us understand much more than cholesterol alone.
Your heart doesn't live in isolation from the rest of your body.
Now for the Really Cool Part: The Coronary Artery Calcium Score
Have you ever wondered:
"Do I actually have plaque in my coronary arteries?"
That's where a coronary artery calcium scan—or CAC scan—may come in.
A CAC scan is a specialized CT scan that looks for calcified plaque in the arteries supplying your heart.
The result is called your:
Coronary Artery Calcium Score
And no—it's not measuring how much calcium you ate.
Calcium in your diet and calcium detected within coronary plaque are very different things.
What Does Your CAC Score Mean?
Here's the simplified version:
CAC = 0
No calcified coronary plaque was detected.
That's reassuring—but it doesn't mean your lifetime cardiovascular risk is zero or that healthy habits no longer matter.
CAC = 1–99
Calcified plaque is present.
Your provider will interpret this number in the context of your age, other risk factors and sometimes your percentile compared with people of similar age and sex.
CAC = 100+
There is a more substantial burden of calcified coronary plaque.
Generally, the higher the CAC score, the greater the amount of calcified plaque and cardiovascular risk.
A CAC score is not a DIY diagnostic test, though.
Whether you should have one—and what to do with the result—is a conversation to have with your physician or other qualified healthcare provider.
Okay, I Know My Numbers. Now What?
This is our favorite part.
Because collecting health data is interesting.
Changing what happens next is the goal.
And nutrition can be incredibly powerful.
A heart-supportive eating pattern doesn't have to mean dry chicken, steamed broccoli and saying goodbye to everything you enjoy.
Think:
🥑 Avocado
🫐 Berries
🫘 Beans and lentils
🥜 Nuts and seeds
🐟 Salmon and other fatty fish
🥦 Plenty of vegetables
🫒 Extra-virgin olive oil
🌾 Whole grains
🍎 Fruit
🥣 Oats and other soluble-fiber-rich foods
In other words:
Eat more plants. Eat more fiber. Choose healthy fats. And make it delicious.
That's a much more sustainable strategy than trying to follow a "perfect" diet.
One Heart-Health Superstar: Fiber
Fiber doesn't get nearly enough attention.
Especially soluble fiber.
Foods like:
Oats • barley • beans • lentils • apples • chia seeds • flax • certain fruits and vegetables
can help support healthy cholesterol levels.
And when food alone isn't getting you there, psyllium fiber may sometimes be helpful.
Your dietitian can help determine an appropriate amount and how to increase fiber gradually—because going from 10 grams of fiber to 30 overnight is an adventure your digestive system probably didn't request.
What About Heart-Health Supplements?
Walk into the supplement aisle and you'd think there's a capsule for everything.
"Cholesterol support!"
"Heart cleanse!"
"Artery health!"
"Cardiovascular miracle mega-ultra formula!"
Okay, we made that last one up.
But you get the idea.
Supplements can have a role—but evidence matters.
Here are a few worth knowing about.
Psyllium
Potential benefit: Helping lower LDL cholesterol.
Psyllium is a concentrated source of soluble fiber and has research supporting its cholesterol-lowering effects when incorporated into an appropriate dietary pattern.
Our philosophy: Start with food. Supplement strategically when appropriate.
Plant Sterols & Stanols
Plant sterols and stanols can reduce cholesterol absorption in the intestine and may modestly lower LDL cholesterol.
They can be found in certain fortified foods and supplements.
Useful tool?
Potentially.
Magic cholesterol eraser?
Nope.
Omega-3s
Omega-3 fatty acids—particularly EPA and DHA—can help lower triglycerides.
Food sources include:
🐟 Salmon
🐟 Sardines
🐟 Trout
🐟 Herring
Here's where things get interesting:
Eating fish and taking a random fish-oil supplement aren't necessarily equivalent.
Research does not support recommending over-the-counter fish oil supplements to everyone simply to prevent heart disease.
Certain prescription omega-3 products, however, have specific medical uses.
So rather than grabbing the biggest bottle at Costco, talk with your healthcare team about whether omega-3 supplementation makes sense for you.
CoQ10
Coenzyme Q10—or CoQ10—often comes up when people experience muscle symptoms while taking statin medications.
Some research suggests it may help certain people.
Other research hasn't found a clear benefit.
Translation:
Promising for some people, but definitely not a universal "everyone on a statin needs this" supplement.
And never stop a prescribed statin because of muscle symptoms without talking with your prescribing provider.
Be Skeptical of the "Artery Cleanse"
Your arteries aren't kitchen pipes.
You can't pour something through them and scrub the plaque away.
So be cautious with supplements claiming to:
❌ "Clean your arteries"
❌ "Melt plaque"
❌ "Replace statins naturally"
❌ "Detox your cardiovascular system"
If the marketing sounds miraculous, that's usually your cue to look more closely at the evidence.
Your Heart-Health Checklist
At your next physical, consider talking with your healthcare team about your overall cardiovascular picture:
Blood pressure
LDL cholesterol
HDL cholesterol
Triglycerides
Non-HDL cholesterol
Hemoglobin A1c / blood glucose
Kidney function
ApoB, when appropriate
Lp(a)—including whether you've ever had it measured
hs-CRP, when clinically appropriate
Family history of premature cardiovascular disease
Whether a coronary artery calcium scan would actually be useful for you
You don't necessarily need every test on this list.
The goal is personalized risk assessment, not ordering every laboratory test available.
Know Your Numbers. Then Know What to Do With Them.
This might be the most important takeaway:
A lab result isn't a nutrition plan.
Knowing that your LDL, ApoB, triglycerides or A1c is elevated doesn't automatically tell you what to eat tomorrow morning.
That's where Medical Nutrition Therapy comes in.
At RI Nutrition Therapy, our registered dietitians can help you connect the dots between your labs, medical history, eating habits and lifestyle.
Instead of simply telling you to "eat healthier," we help answer questions like:
What should I eat to help lower my LDL?
How much fiber should I actually be getting?
Which fats should I eat more—or less—of?
How can I improve my triglycerides?
Do I need a supplement?
What changes will give me the biggest return for my effort?
And perhaps most importantly:
How can I do this without feeling like I'm on a diet for the rest of my life?
Your Heart Works 24/7. Give It Some Love.
You don't need to overhaul your life tomorrow.
Start with one meal.
One walk.
One extra serving of vegetables.
One fiber-rich breakfast.
One conversation with your healthcare provider.
One appointment with your dietitian.
Small choices add up—and prevention is powerful.
