After more than 25 years as a registered dietitian, I’ve learned that one of the hardest parts of ‘heart-healthy’ isn’t fat or carbs – it’s confusion and misinformation. Knowledge evolves, headlines shout absolutes, and advice that was cutting edge a decade ago can feel trite now. That doesn’t mean experts are fickle. It means science refines itself – we get sharper lenses, better measurements, and a clearer picture of what truly protects or harms our heart and vascular wellbeing.
When I started out in the late ’90s, the guidance was all-or-nothing: fat bad, cholesterol bad, low-fat everything, avoid egg yolks, buy skim milk, opt for margarine, and let oatmeal and Cheerios work their magic.
Today, the conversation goes much deeper: inflammation and metabolic health, lipid particle number (ApoB) and genetics (Lp(a)), sleep and stress physiology, resistance training and body composition, and the very real difference between a fried chicken biscuit and an avocado omelet – even if a nutrition app says the saturated fat looks similar. Context matters. Our daily habits matter.
What follows isn’t a list of tips. It’s how I approach heart health now – through the lens of science and experience, including my own.
Beyond LDL: The markers that matter most
Despite an active lifestyle, healthy weight, and a nutrient-dense diet (along with no alcohol and very few ultra-processed foods), my LDL cholesterol crept from comfortably under 120 mg/dL into the mid-160s – and stayed there.
I interviewed Carl “Chip” Lavie, MD, cardiologist at Ochsner for my podcast, and his message was clear: LDL matters, but it’s not the whole story. When LDL is elevated, it’s okay to ask your provider for a deeper look.
Some individuals with elevated LDL are actually at a lower risk than they feared, while others may uncover additional red flags. More data helps us make more precise decisions, including whether to prioritize lifestyle for three to six months or consider medication sooner.
Two additional tests that Dr. Lavie recommends are lipoprotein(a) and a cardiac CT calcium score.
Lipoprotein(a) or Lp(a), is largely genetic and an independent risk factor; the optimal range is less than 30 mg/dL. Elevated levels are associated with an increased risk of plaque buildup in arteries, blood clots, and inflammation – all risk factors for heart attack and stroke.
Cardiac CT calcium score measures calcification in the arteries. A score of zero is ideal, indicating no significant blockage. Higher scores suggest increased risk.
Other key markers to consider when LDL is elevated:
- Apolipoprotein B (ApoB): ApoB directly counts the number of atherogenic (plaque-promoting) particles circulating in the bloodstream. Fewer particles mean less “traffic” capable of penetrating arterial walls and triggering plaque formation.
- LDL particle number and size: Not all LDL behaves the same. Small, dense LDL particles are more likely to infiltrate artery walls and contribute to atherosclerosis, whereas larger, ‘fluffier’ LDL particles are considered less harmful. Knowing particle type and size helps to understand risk.
- High-sensitivity C-reactive protein (hs-CRP): This blood marker reflects systemic inflammation, which plays a major role in plaque instability. Even mildly elevated inflammation levels can increase cardiovascular risk, particularly when paired with abnormal lipids.
Dr. Lavie also recommends the Atherosclerotic Cardiovascular Disease (ASCVD) calculator to estimate 10-year risk of heart attack or stroke. It’s available online and incorporates multiple variables to give a more complete picture of risk.
Red Yeast Rice: A natural alternative
Back to my own challenges with a steadily rising LDL: since the rest of my health profile was reassuring, my physician’s take was that we didn’t need to talk statins until my LDL approached the 190s.
I wasn’t comfortable just watching and waiting, though, especially since it had only continued to rise. With my providers looped in, I started taking red yeast rice, a natural source of monacolin K, which acts similarly to a low-dose statin.
At 600 mg daily, my LDL dropped from 164 to 143 mg/DL in 12 weeks. It hovered there for a few months, so I increased the dose to 1,200 mg – and it dropped to 108 mg/dL.
This isn’t a blanket recommendation. Red yeast rice isn’t risk-free; it can affect liver enzymes and should never be combined with a statin. But it’s an example of a personalized, data-guided approach: test, intervene thoughtfully, re-test, and let your numbers drive decisions.
To be clear, I’m not anti-medication. If risk is severe or urgent, medication can be lifesaving. When it isn’t, I encourage a trial of lifestyle first – improvements in nutrition and movement – with a defined window (12–24 weeks) and follow-up labs. That way, you’ll know what your body can do before layering on a prescription.
It’s not either/or; it’s about strategy and clarity. Progress happens when we use the right tools, in the right order, with the right health providers, for the right person.
And that same principle applies to nutrition. Unfortunately, this is also where we tend to run into outdated or oversimplified guidance (or worse, advice individuals with no formal training on the topic – especially those that stand to make a profit from our wellness choices). So let’s step into the bigger picture: what does a modern, heart-supportive style of eating actually look like today?
Translating the Mediterranean Diet into modern practice
“Follow the Mediterranean Diet” is a common recommendation – and a vague one. The heart-protective version isn’t a prescription of pasta, focaccia and nightly wine. It’s plant-forward plates filled with non-starchy vegetables and herbs; generous amounts of extra-virgin olive oil; seafood often; modest portions of whole grains and legumes. Meat is used sparingly – more as an accent than the main event.
The oatmeal and Cheerios reality check
Soluble fiber does helps lower LDL – but studies have used 5 to 10 grams per day. In practical terms, it would take 3+ cups of cooked oatmeal or 10+ cups of Cheerios to reach the upper end of this range. A more realistic approach is to layer sources:
- Add psyllium husk (about 3 grams soluble fiber per teaspoon) to yogurt or a smoothie.
- Use chia and ground flaxseed liberally.
- Include beans and lentils as part of an overall soluble-fiber-rich pattern.
The bottom line: Oats are great, but a typical bowl isn’t enough on its own to create the LDL drop people expect.
Eggs: bringing the yolk back
It’s true that egg yolks are high in cholesterol. For most of us, though, dietary cholesterol has minimal impact on our blood levels of cholesterol. Eggs are also relatively low in saturated fat and rich in choline, B12, lutein, and zeaxanthin – nutrients that can be hard to find elsewhere, especially all in one package. For healthy adults, an egg a day typically fits just fine (as always, talk with your provider about what’s best for you).
Dairy, reconsidered
The evidence has shifted here as well: moderate dairy intake – reduced-fat or full-fat – appears generally neutral to modestly beneficial for cardiovascular outcomes in healthy people. Fermented dairy, such as plain Greek yogurt or kefir, shows some of the strongest benefit.
For those with elevated LDL, established heart disease, or weight-management goals, reduced-fat options are still a solid fit; my preference is usually reduced-fat rather than fat-free. And of course, watch for added sugars.
Omega-3s: DHA + EPA
Fish oil supplements don’t seem to budge LDL much, but omega-3s (EPA + DHA) can lower triglycerides, reduce inflammation, and support healthy heart rhythm. I typically recommend at least 2-3 servings of omega-3-rich fish per week – think salmon, sardines, or tuna – and omega-3 supplementation if intake is low.
Ultra-processed foods: the overlooked factor
And beyond any single nutrient, one of the strongest patterns emerging in cardiovascular research is centered on how foods are made.
Large-scale studies now link high consumption of ultra-processed foods – those packaged snacks, sugary drinks, and even many ‘diet’ or ‘low-fat’ items – with higher rates of cardiovascular disease and stroke. These foods promote inflammation, raise blood pressure, disrupt the gut microbiome, and contribute to insulin resistance – even when calories and nutritional content look similar on paper.
We don’t have to eliminate all processed foods, but reducing ultra-processed products from our diet – especially packaged snacks and sweetened drinks – just may be one of the most powerful steps we can take for our heart health.
Alcohol: updating an old story
For years, we heard that a nightly glass of red wine was “good for our heart” — a message that has lingered for decades. Much of that early research was based on flawed observational studies: moderate drinkers tended to be healthier overall, and many “non-drinkers” in those studies were actually people who had stopped drinking due to illness. The narrative was further reinforced by the alcohol industry, which helped shape public perception of wine as a heart-healthy staple.
Newer, more rigorous studies paint a clearer picture — one that contradicts alcohol’s so-called “heart-healthy” reputation.
Alcohol & Anxiety: when the fix becomes the problem
We often turn to alcohol to relax – to take the edge off, unwind, and quiet our racing thoughts. And in the moment, it can feel like it works. But when drinking becomes a regular part of our routine, it actually has the opposite effect, priming the body for more anxiety, not less.
Here’s why: alcohol temporarily suppresses the central nervous system, creating a temporary sense of calm. But as it wears off, the brain rebounds by releasing more stress hormones and ramping up neural excitability – essentially over-sensitizing our body’s stress response. That means reacting to small stressors as if they’re major events, leaving us on edge and emotionally overcharged.
It’s an easy cycle to miss because it feels like it’s helping in the short term, yet over time it amplifies the very stress and anxiety we’re trying to manage.
That same rebound effect also interferes with sleep – another key player in mood and cardiovascular health. Alcohol shortens and disrupts the REM cycle, the phase most critical for emotional regulation. So while it might help us fall asleep faster, it robs us of deep, restorative rest – which, in turn, fuels anxiety and inflammation.
Alcohol, cancer and heart disease: The bigger picture
Health organizations now emphasize that there is no safe level of alcohol for cancer risk – with the National Cancer Institute noting that even light drinking increases breast cancer risk – roughly 7–10% higher per alcohol-containing drink per day – with risk rising exponentially at higher intakes.
Cardiovascular issues are clearer too: blood pressure increases even at low levels, and risk of atrial fibrillation increases about 6% for each additional daily drink. The American Heart Association’s current stance is straightforward: if you don’t drink, don’t start for your heart.
For most of us – especially women – any potential benefit is outweighed by the risks, including breast cancer, blood pressure, arrhythmias, sleep disruption, and anxiety. In a city that celebrates most things with a cocktail, this can be a tough truth; but also one that I hope is empowering. If heart health is the goal, alcohol simply isn’t part of the prevention plan – and is actually working against us.
Other pillars to consider
And all of this works even better alongside the basics we too often overlook:
- Sleep: Short or poor-quality sleep keeps cortisol and inflammation elevated – neither are good for cardiovascular wellbeing.
- Stress: Chronic stress shifts blood pressure, blood sugar, and cravings; regular practices like focused breathing or movement help offset daily stressors.
- Movement: Speaking of movement, it doesn’t have to be a structured workout – walking, gardening, or playing with kids or pets all count.
Putting it together — what really matters
Invest in sleep, stress coping skills, regular movement, and strength. Every one of those inputs supports your heart and vascular wellbeing as much as your mindset.
Heart health, at its core, isn’t about eating perfectly or fearing the wrong foods — it’s about making informed choices with clarity instead of anxiety. When we understand the “why” behind our decisions, nutrition stops feeling restrictive and becomes a way of living that supports a strong, steady rhythm for years to come.
