You have your annual bloodwork done and receive the familiar message:
“Your cholesterol is high.”  For many people, the next conversation quickly becomes: Do I need to take a statin?

That is an important discussion to have with your physician. But it doesn’t have to be the end of the conversation. An elevated cholesterol result can also be an opportunity to step back and ask:

What does this tell us about my overall cardiovascular health, why might these numbers be elevated, and what else can I do to protect my heart and arteries?

Cholesterol has an important job
Despite its reputation, cholesterol isn’t inherently “bad.” Your body needs cholesterol to build cell membranes and produce steroid hormones (like cortisol, estrogen, progesterone, testosterone), bile acids and vitamin D.
Because cholesterol and other fats can’t travel freely through the bloodstream, they are transported inside particles called lipoproteins.
A standard lipid panel usually measures:

  • Total cholesterol
  • LDL cholesterol (LDL-C)
  • HDL cholesterol (HDL-C)
  • Triglycerides

All of these numbers provide useful information. LDL-C, in particular, is an established cardiovascular risk factor and shouldn’t be dismissed simply because other aspects of someone’s health look good.

But LDL-C is still only one part of cardiovascular risk assessment.
Cholesterol isn’t the same thing as the particle carrying it.  One helpful distinction is the difference between LDL cholesterol and LDL particles. LDL-C tells us how much cholesterol is being transported within LDL particles. It doesn’t directly tell us how many atherogenic particles are circulating.

Why does particle number matter?  Atherogenic particles can enter and enter the arterial wall, starting the processes involved in the development of atherosclerotic plaque. So someone can have an LDL-C value that doesn’t fully reflect the number of potentially atherogenic particles circulating in their blood. Some particles are inflammatory (small/dense), others are not (large/fluffy) so understanding your pattern is important. This is one reason additional markers such as Apolipoprotein B (ApoB) can sometimes add important information. We’ll take a closer look at ApoB and other cardiovascular tests in Part 2 of this series.

The next question: Why is cholesterol elevated?  This is where the conversation can become much more useful. Rather than looking only at how to lower a laboratory value, we can also investigate the factors that may be influencing it.

1. Metabolic health
Insulin resistance, elevated blood sugar, visceral adiposity (fat around organs in the mid-section) and high triglycerides can alter lipid metabolism and increase cardiovascular risk. This is why evaluating glucose, HbA1c and sometimes fasting insulin can provide useful context alongside a cholesterol panel.

2. Thyroid function
Thyroid hormones help regulate cholesterol metabolism and LDL clearance. Inadequate thyroid hormone activity can contribute to elevated LDL cholesterol. For someone with unexplained changes in cholesterol, looking at thyroid function can therefore be an important part of the investigation. It doesn’t always take diagnosed “hypothyroidism” to have an effect, sometimes suboptimal conversion is enough.

3. Menopause and hormonal changes
The transition through menopause can affect LDL, body-fat distribution, insulin sensitivity and vascular health. A cholesterol pattern that changes significantly during midlife deserves to be considered within this larger physiological context rather than viewed as an isolated event.

4. Genetics
Sometimes the explanation is largely genetic. Familial hypercholesterolemia and other inherited differences in lipid metabolism can produce elevated cholesterol even in someone who exercises regularly, maintains a healthy weight and eats an excellent diet. One largely genetic cardiovascular risk factor, Lp(a), isn’t usually included on a standard cholesterol panel.  This is an important reminder that elevated cholesterol isn’t always evidence that someone is “doing something wrong.” However, more often than not people assume the issue is genetic because other family members have had high cholesterol issues – these can be due to many of the other factors listed here and not necessarily “genetic”.

5. Nutrition and lifestyle
Diet still matters but the conversation should extend beyond simply eating less dietary cholesterol which for most is not the problem. Overall dietary pattern, fiber intake, dietary fat composition, plant diversity, highly processed foods, alcohol, physical activity, smoking, sleep, stress, blood pressure and body composition can all contribute to cardiovascular health.The goal is to understand the individual’s pattern, rather than apply exactly the same dietary prescription to everyone with an elevated LDL.

6. And then there is inflammation
Atherosclerosis involves more than lipids circulating through a passive set of pipes. Our arteries are living tissue lined by the vascular endothelium, a metabolically active layer of cells involved in vascular tone, blood clotting, immune signaling and inflammation. Atherogenic lipoproteins are important drivers of atherosclerosis, but the environment in which those particles circulate also matters. High blood pressure, smoking, elevated blood sugar, oxidative stress and chronic inflammatory signaling can all negatively affect vascular health. This gives us another important shift in perspective: Our goal isn’t simply to lower cholesterol. Our goal is to protect the artery.

What about statins?
Statins have substantial evidence demonstrating their ability to lower LDL cholesterol and reduce cardiovascular events in appropriately selected individuals. For some people, particularly those with existing cardiovascular disease, familial hypercholesterolemia, diabetes or significant overall cardiovascular risk, medication may be an important component of prevention or treatment.  For others, the decision may be less straightforward and require a more individualized discussion of overall risk.

However, lowering LDL doesn’t necessarily eliminate cardiovascular risk

This is an important distinction that can get lost in the cholesterol conversation. Statins have been shown to significantly reduce cardiovascular events but risk reduction isn’t the same thing as risk elimination.

Across large randomized statin trials, lowering LDL cholesterol by approximately 39 mg/dL has been associated with about a 22% reduction in major vascular events. In some individual trials and populations, the relative risk reduction has been considerably greater. But cardiovascular events still occur in people whose LDL has been successfully lowered. For example, in the JUPITER trial, rosuvastatin lowered LDL cholesterol by approximately 50% and reduced the primary cardiovascular endpoint by 44% compared with placebo, an impressive benefit yet events weren’t eliminated.

Residual risk becomes even more apparent in people who already have cardiovascular disease. In the IMPROVE-IT trial of patients who had recently experienced an acute coronary syndrome, approximately 35% of those receiving statin therapy experienced another major cardiovascular endpoint over seven years. Even with additional cholesterol-lowering therapy that brought average LDL cholesterol down to approximately 54 mg/dL, cardiovascular events continued to occur.  This remaining vulnerability is often referred to as residual cardiovascular risk.

And it reinforces an important point: Lowering atherogenic cholesterol is one important way to reduce cardiovascular risk, but it doesn’t address every factor that contributes to cardiovascular disease.

Blood pressure, insulin resistance and blood-sugar regulation, smoking, inflammation, body composition, physical activity, sleep, genetics such as elevated Lp(a), and the health of the vascular system itself can all influence someone’s remaining risk.

This is why taking a statin shouldn’t mean that the rest of cardiovascular prevention becomes less important.  Medication can lower an important risk factor. The larger goal is still to protect the entire cardiovascular system. Simply taking a cholesterol lowering medication does not fully protect someone from cardiovascular disease or events. 

A comprehensive approach doesn’t have to be statin versus lifestyle. It can be: What combination of medical treatment (if indicated), nutrition, movement, metabolic support and risk-factor modification gives this individual the best opportunity to maintain healthy arteries over the long term?  These approaches are complementary, not mutually exclusive.

What can you start doing now?
Even before you know exactly what’s contributing to your cholesterol pattern, there are several strategies that support cardiovascular health across a wide range of risk profiles.

Build meals around whole, minimally processed foods. Emphasize vegetables, fruits, legumes as tolerated, nuts and seeds, quality protein sources and other nutrient-dense whole foods while reducing highly processed foods.

Prioritize fiber—especially soluble fiber. Foods such as oats, barley, beans and lentils, chia and flax seeds, fruits and vegetables help support cholesterol metabolism, blood-sugar regulation and the gut microbiome. For many adults, gradually working toward at least 25–30 grams of total fiber per day is a useful starting point, with individual needs sometimes higher.

Consider both the source and amount of dietary fat. Saturated fat can raise LDL cholesterol and ApoB, although individual response varies and the whole food source matters, not all saturated-fat-containing foods appear to have identical cardiovascular effects. Rather than simply pursuing a “low-fat” or rigidly low-saturated-fat diet, look at the overall dietary pattern and where saturated fat is coming from. When LDL-C or ApoB is elevated, replacing some sources of saturated fat with foods rich in mono- and polyunsaturated fats such as extra-virgin olive oil, nuts, seeds, avocado and fatty fish may be beneficial. An individualized dietary trial followed by repeat testing can also help determine how much your lipid profile actually responds to changes in dietary fat.

Move regularly and include resistance training. Cardiovascular exercise supports heart and vascular health, while strength training helps preserve muscle and improve glucose regulation and metabolic health. Both matter.

Don’t overlook blood sugar and blood pressure. Cardiovascular prevention isn’t only about cholesterol. Maintaining healthy glucose regulation and blood pressure reduces stress on the vascular system and should be part of the same conversation.

Protect sleep and avoid tobacco exposure. Consistent restorative sleep supports cardiometabolic health (checking for and managing sleep apnea is critical), while smoking and other tobacco exposure remain major modifiable cardiovascular risk factors.

You don’t need to wait for a perfect testing plan to begin supporting your cardiovascular system. But if your cholesterol is already elevated, generic advice may not be enough.

Where functional nutrition fits
This is one area where working with both your physician and a qualified functional nutrition professional can be particularly valuable. Your physician can assess your medical cardiovascular risk, determine whether additional medical evaluation or imaging is appropriate, diagnose conditions requiring treatment and discuss whether cholesterol-lowering medication is indicated.

A functional nutrition professional can work alongside those recommendations to take a deeper look at the modifiable factors that may be contributing to your individual pattern.
That might include evaluating:

  • dietary composition and fiber intake
  • blood-sugar regulation and insulin resistance
  • thyroid and hormonal considerations to discuss with your medical provider
  • body composition and activity
  • nutrient status
  • gastrointestinal and microbiome health when clinically relevant
  • sleep and stress physiology
  • inflammatory contributors
  • family history and patterns that warrant additional medical testing

The objective isn’t to find an alternative explanation that allows us to ignore high cholesterol. It’s to make sure we’re not missing opportunities to improve the rest of the cardiovascular terrain while appropriately addressing cholesterol itself. 

Want to understand what’s behind your numbers?
When I work with clients with elevated cholesterol or other cardiovascular risk markers, we don’t simply look for a list of foods to remove. We look at the whole pattern.  We can review your existing laboratory results, dietary and lifestyle patterns, health history and potential underlying contributors. When appropriate, I can also help identify additional laboratory markers worth discussing or obtaining such as ApoB, Lp(a), fasting insulin or hs-CRP and help you understand how those findings fit together.  From there, we can build a targeted nutrition, lifestyle and supplement strategy to address the factors we can modify, while you continue to work with your physician on medication, imaging and other medical recommendations when needed.

If you’ve been told your cholesterol is high and you’re ready to understand the bigger picture rather than simply watching the number, this is exactly the type of investigation we can do together.
