Understanding High Cholesterol: Debunking Myths

About 25 million adults in the U.S. over the age of 20 face high cholesterol levels. If you’re one of them, you’re definitely not alone in seeking ways to lower it. There’s a lot of confusion swirling around the topic. Some folks think dietary cholesterol is the main culprit, while others point to genetics. With so much misinformation, it can be tricky to know what actions to take.

But don’t fret! We’ve connected with dietitians to clarify some common myths surrounding high cholesterol, providing insights backed by experts. Here’s what you really need to know to effectively manage your cholesterol levels and enhance your heart health.

Myth #1: Avoid Dietary Cholesterol

Many people have heard they should ditch foods like eggs after being diagnosed with high cholesterol. The prevailing belief was that dietary cholesterol led to higher cholesterol levels. However, recent studies indicate that dietary cholesterol has a minimal impact on blood cholesterol. Instead, saturated and trans fats play a more significant role in increasing LDL cholesterol levels.

“Instead of cutting out cholesterol-rich foods entirely, I advise my clients to limit saturated fats found in fatty meats and full-fat dairy,” suggests Marissa Beck, a registered dietitian. She also recommends incorporating heart-healthy fats from nuts, seeds, avocados, and fatty fish.

Myth #2: Dietary Changes Can Fix High Cholesterol

Sure, making dietary changes is beneficial for improving cholesterol levels, but they might not be enough on their own. “Cholesterol levels can be affected by various other factors including sleep, stress, and genetics,” emphasizes Patricia Kolesa, another dietitian. She highlights the importance of setting small, achievable goals outside of diet—like improving sleep quality and engaging in regular physical activity.

Myth #3: You Need to Cut Out All Dietary Fats

It’s a common misconception that all fats should be eliminated if you have high cholesterol. While some fats can indeed promote high cholesterol, not all fats are the same. “Certain fats can help reduce the risk of high cholesterol,” says Carly Hart, reinforcing that unsaturated fats can actually increase HDL (the good cholesterol) and lower LDL (the bad kind).

Instead of completely avoiding fats, aim to incorporate more unsaturated fats into your diet, such as those found in avocados, nuts, and fatty fish, while reducing saturated fat intake.

Myth #4: You Can Tell If You Have High Cholesterol By Your Symptoms

Most individuals with high cholesterol don’t exhibit any symptoms, making it difficult to know if you have it without testing. Some might display symptoms like fatty deposits, but these are often linked to severe cases. Regular check-ups are crucial to monitor your cholesterol levels.

Myth #5: You Can Only Have High Cholesterol at a Higher Body Weight

It’s a common belief that only individuals with larger body sizes can face high cholesterol, but that’s not entirely true. “Genetics, family history, and diet are significant factors,” shares Mandy Willig, indicating that everyone, regardless of size, should get regular cholesterol screenings.

Adults over 20 should ideally be checked every five years, or annually if they have diabetes or a family history of heart issues. Keeping an eye on your cholesterol allows for early identification of potential issues.

Myth #6: You Don’t Need to Worry About Cholesterol Until You’re Older

High cholesterol can indeed develop at any age, often starting early, especially if there’s a family history involved. According to Alexandria Hardy, about 7% of children and teens between 6 and 19 years old have high cholesterol. It’s wise to pay attention to eating habits and lifestyle choices early on. Building good habits—like incorporating fiber-rich foods and engaging in regular physical activity—can pay off in the long run.

Other Tips for Lowering Cholesterol

While changes in diet and lifestyle can certainly help, at times, they might not be sufficient, and medication may be necessary. Here are some simple steps you can start today to lower your cholesterol:

• Limit Added Sugars: Be conscious of added sugars, often hidden in packaged foods. The American Heart Association suggests keeping added sugars to less than 6% of daily calories.
• Fill Up on Fiber: A high-fiber diet can aid in reducing LDL and overall cholesterol. Aim to include more fruits, vegetables, whole grains, and legumes.
• Limit Alcohol: Heavy drinking is linked to higher cholesterol. Cutting back on alcohol can significantly influence your cholesterol levels and overall heart health.
• Do Cardiovascular Exercise: Regular exercise can raise HDL cholesterol and lower LDL levels. Aim for activities that elevate your heart rate, like brisk walking or swimming, and try to stay active each day.

The Bottom Line

High cholesterol is a common issue, but understanding the facts can help you manage it effectively. By focusing on boosting your fiber intake, embracing heart-healthy fats, and staying active, you can make a positive difference. Remember, lifestyle changes are important, but regular monitoring and guidance from health professionals are key for long-term success.
