The Truth about Heart Disease and Cholesterol

Imagine being told that almost everything you believed about heart disease and cholesterol might not be accurate. Unfortunately, we’ve been fed many misconceptions about these critical health topics.

In this article, we’re diving into a topic that’s close to my heart (pun intended) and probably yours too: heart disease and cholesterol. Let’s set the record straight and dive into the truth about heart disease and cholesterol. It’s time to empower you with knowledge that can truly make a difference in your health.

The Big Lie: Cholesterol as the Main Culprit

Have you ever heard that high cholesterol is the main villain causing heart disease? If so, you’re not alone. For years, we’ve been told that dietary cholesterol—what we eat—directly leads to heart disease. But guess what? That’s not the whole truth. In fact, labeling cholesterol as the enemy might be one of the biggest misunderstandings in modern medicine.

To truly understand how we got here, let’s take a quick trip back to the early 1900s. In those days, heart disease was quite rare in the United States. But fast forward to today, and heart disease is an epidemic. Something changed along the way.

Back then, there wasn’t the same level of processed food and unhealthy lifestyles we often see now. The transition from minimal heart disease to where we are today involves complex factors, but blaming cholesterol alone oversimplifies a more complex issue.

Cholesterol: The Misunderstood Molecule

For decades, we’ve been told that cholesterol, especially the kind we get from our diet, is the big bad wolf when it comes to heart disease. It’s been drilled into our heads that if we want a healthy heart, we need to cut out cholesterol-rich foods and lower our cholesterol levels at all costs. But what if I told you that this widely accepted “fact” might not be the whole truth?

Let’s talk about cholesterol itself. It’s a waxy, fat-like substance found in every cell of your body. Your body needs cholesterol to build cells, produce hormones, and even to make vitamin D. So, it’s not the enemy; rather, it plays vital roles in our health.

The Types of Cholesterol

Not all cholesterol is the same. You’ve probably heard terms like “good cholesterol” and “bad cholesterol.” Let’s break these down:

LDL (Low-Density Lipoprotein): Often called “bad cholesterol,” high levels can lead to plaque buildup in arteries, increasing heart disease risk.

HDL (High-Density Lipoprotein): Known as “good cholesterol,” it helps remove other forms of cholesterol from your bloodstream.

Balance is key. What’s crucial is the ratio between LDL and HDL rather than just the total cholesterol number. Too much LDL and not enough HDL can indeed create problems.

The Great Cholesterol Myth

The idea that cholesterol causes heart disease is based on some pretty shaky science from way back. In the 1950s, a researcher named Ancel Keys conducted a study that seemed to show a link between dietary fat, cholesterol, and heart disease. This study, known as the Seven Countries Study, became the foundation for dietary guidelines that have shaped our eating habits for decades.

But here’s the thing: Keys’ study had some serious flaws. He cherry-picked data from countries that supported his hypothesis and ignored data from countries that didn’t fit his theory. When you look at the full data set, the link between dietary cholesterol and heart disease becomes much less clear.

Heart Disease and Cholesterol

What Really Causes Heart Disease?

So if cholesterol isn’t the main culprit, what is? The truth is, heart disease is complex, and there isn’t just one cause. But research is pointing to some key factors that might surprise you:

  1. Inflammation: This is a big one. Chronic inflammation in your body can damage your blood vessels and lead to the formation of plaques that can cause heart attacks and strokes.
  2. Insulin resistance: When your body becomes resistant to insulin, it can lead to high blood sugar levels, which can damage your blood vessels and increase your risk of heart disease.
  3. Stress: Chronic stress can wreak havoc on your body, including your heart. It can lead to high blood pressure, inflammation, and other risk factors for heart disease.
  4. Poor diet: But not in the way you might think! A diet high in processed foods, refined carbohydrates, and industrial seed oils (like soybean and canola oil) can contribute to inflammation and insulin resistance.
  5. Sedentary Lifestyle: Our increasingly sedentary lives don’t help either. Lack of physical activity is a significant risk factor for heart disease.

What About Statins?

If you’ve been diagnosed with high cholesterol, chances are your doctor has recommended statins. These drugs are designed to lower cholesterol levels, and they’re some of the most prescribed medications in the world.

But here’s the thing: while statins can effectively lower cholesterol levels, their impact on heart disease risk isn’t as clear-cut as you might think. Some studies have shown that statins can reduce the risk of heart attacks in people who already have heart disease, but their benefits for healthy people are less certain.

Moreover, statins come with potential side effects, including muscle pain, increased risk of diabetes, and cognitive issues. It’s important to have an open and honest conversation with your healthcare provider about the potential risks and benefits of statins for your individual situation.

So, What Should You Eat?

If cholesterol isn’t the enemy, does that mean we can eat whatever we want? Not quite. While dietary cholesterol might not be the heart health villain it’s been made out to be, that doesn’t mean all foods are created equal when it comes to heart health.

Here are some tips for a heart-healthy diet:

  1. Embrace whole foods: Focus on foods that are as close to their natural state as possible. This includes plenty of vegetables, fruits, nuts, seeds, and high-quality proteins.
  2. Don’t fear healthy fats: Fats from sources like olive oil, avocados, nuts, and fatty fish can actually be good for your heart.
  3. Limit processed foods: Highly processed foods often contain unhealthy fats, added sugars, and other ingredients that can contribute to inflammation and insulin resistance.
  4. Mind your carbs: While carbohydrates aren’t inherently bad, excessive consumption of refined carbs like white bread, pasta, and sugary snacks can contribute to insulin resistance and inflammation.
  5. Consider your individual needs: Remember, there’s no one-size-fits-all approach to nutrition. What works for one person might not work for another.

Practical Tips for Heart Health

While what you eat is important, it’s not the only factor in heart health. Here are some other lifestyle changes that can make a big difference:

  1. Get moving: Regular physical activity is one of the best things you can do for your heart. Find an activity you enjoy and make it a regular part of your routine.
  2. Manage stress: Chronic stress can take a toll on your heart. Find healthy ways to manage stress, like meditation, yoga, or spending time in nature.
  3. Prioritize sleep: Poor sleep is associated with an increased risk of heart disease. Aim for 7-9 hours of quality sleep each night.
  4. Quit smoking: If you smoke, quitting is one of the best things you can do for your heart (and overall health).
  5. Stay connected: Social connections are important for heart health. Make time for relationships and activities that bring you joy.

The Bottom Line

The truth about heart disease and cholesterol is more complex than we’ve been led to believe. While cholesterol plays a role in heart health, it’s not the whole story. By focusing on reducing inflammation, improving insulin sensitivity, managing stress, and adopting a healthy lifestyle, you can take significant steps towards protecting your heart.

Remember, your health journey is unique to you. What works for someone else might not work for you, and that’s okay. By arming yourself with knowledge and making informed choices, you can take control of your heart health and live your best life. Here’s to your healthy heart!

Hi! I’m Dr. E, The NP with a PHD. Several years ago, my wife was diagnosed with an autoimmune disease and the only options given to us were heavy duty medications.

We KNEW there had to be a better way. After a long search, we discovered functional medicine.

With functional medicine we found alternative ways we were able to manage her disease and get her back to feeling like her old self.

We discovered that this way of life not only helps people with various issues, including autoimmune, chronic issues and “I-don’t-feel-good-itis.”

Functional medicine drastically changed our lives and using it I developed The KNEW Method to help others who are suffering or not feeling optimal.

Let’s work together to get you to feeling like your old self again.
