The Truth About Cholesterol: What You Eat Isn’t the Problem

Cholesterol has been misunderstood for decades. From outdated dietary guidelines to viral social media posts, the myth persists: eating cholesterol-rich foods like eggs will raise your blood cholesterol and increase your risk of heart disease. But the science tells a different story, one that’s far more nuanced and empowering.

WHAT CHOLESTEROL ACTUALLY DOES  

Cholesterol isn’t a villain. It’s a vital substance your body uses to build cell membranes, produce hormones, and support brain function. In fact, your liver produces the majority of the cholesterol in your body, regardless of how much you consume through food. This internal production is tightly regulated. When you eat more cholesterol, your body naturally produces less. When you eat less, it ramps up production to meet physiological needs.

DIETARY CHOLESTEROL VS. BLOOD CHOLESTEROL  

The confusion stems from conflating dietary cholesterol with blood cholesterol. They are not the same. The cholesterol you eat has minimal impact on the cholesterol circulating in your bloodstream. Numerous studies have shown that for most people, consuming cholesterol-rich foods does not significantly raise LDL (the so-called “bad” cholesterol) or lower HDL (the “good” cholesterol). The body’s internal regulation system is far more influential than your breakfast choices.

THE EGG MYTH  

Eggs have been unfairly demonized for years. They’re one of the most nutrient-dense foods available, packed with high-quality protein, vitamins, and yes, cholesterol. But research consistently shows that eggs do not raise blood cholesterol levels in healthy individuals. In fact, they may improve your lipid profile by increasing HDL and supporting metabolic health. The fear around eggs is rooted in outdated science, not current evidence.

THE REAL CULPRITS: PROCESSED FOODS AND SEED OILS  

If we’re going to talk about elevated cholesterol, we need to shift the spotlight. Highly processed foods, especially those loaded with refined sugars, artificial additives, and industrial seed oils, are far more disruptive to metabolic health than dietary cholesterol. These foods promote chronic inflammation, which damages blood vessels and alters lipid metabolism. Inflammation also interferes with insulin signaling, leading to insulin resistance, a key driver of metabolic syndrome and dysregulated cholesterol production.

Excessive consumption of seed oils like soybean, corn, and canola, often found in packaged snacks, fast food, and restaurant meals, introduces an imbalance of omega-6 fatty acids. While omega-6s are essential in moderation, too much can tip the scale toward pro-inflammatory pathways. This chronic low-grade inflammation can elevate LDL levels, reduce HDL, and impair the body’s ability to manage cholesterol effectively.

In short, it’s not the eggs or shrimp that are causing the problem. It’s the ultra-processed food landscape that’s quietly reshaping our metabolic health from the inside out.

CONCLUSION  

It’s time to retire the myth that eating cholesterol-rich foods will wreck your heart health. Your body is smarter than that. It adjusts its own cholesterol production based on what you eat, and for most people, dietary cholesterol has little to no impact on blood levels. Eggs aren’t the enemy. Misinformation is. Focus on whole foods, movement, and metabolic health, and let cholesterol do its job.
