Why Dietary Cholesterol Shouldn’t Be Considered a Villain
Studies indicate that dietary cholesterol has minimal effect on blood cholesterol levels. So, what truly influences it?
For many years, cholesterol has been deemed a major culprit in heart disease, leading many to be advised against consuming eggs and animal fats. However, cholesterol is essential for supporting overall health.
This substance stabilizes cell membranes, aids in the synthesis of steroid hormones such as cortisol, testosterone, and estrogen, and plays a role in the body’s natural healing mechanisms. Additionally, cholesterol is vital for the production of vitamin D when the skin is exposed to sunlight, it helps to alleviate inflammation, and it protects nerve cells.
Nonetheless, it may not be solely about the foods we consume but rather how our bodies metabolize and handle cholesterol.
Understanding Cholesterol
“Cholesterol itself is not detrimental; the concern arises when LDL cholesterol oxidizes,” explained Jodi Duval, a naturopathic physician and owner of Revital Health, to The Epoch Times.
LDL (low-density lipoprotein, often referred to as “bad” cholesterol) is synthesized by the liver and sent to body parts requiring repair. It functions as a healing agent and a fundamental component for cell regeneration. However, when LDL undergoes oxidation, it becomes harmful.
This oxidation occurs when cholesterol interacts with oxygen. Reactive oxygen species (ROS), or free radicals, can harm LDL particles, leading to inflammation and plaque formation in arteries, which contributes to atherosclerosis, a major factor in heart disease.
Managing cholesterol levels should primarily take metabolic syndrome, insulin resistance, and other cardiovascular risk factors into account, Duval noted.

It’s important to recognize that cholesterol isn’t just one factor; it exists in various forms, including LDL and high-density lipoprotein (HDL). HDL is commonly referred to as “good” cholesterol because it assists in removing excess cholesterol from the bloodstream and transports it to the liver for processing.
Impact of Diet on Blood Cholesterol
The conversation around dietary cholesterol has been ongoing since the 1960s when experts first advised limiting its intake.
“For the majority of individuals, cholesterol intake has a limited effect on the cholesterol present in the bloodstream,” stated Dr. Garrett Garner, an obstetrician-gynecologist and medical director at SimpleFix, an online pharmacy platform.
The Liver’s Essential Function
Given that diet has a less significant impact on cholesterol management than commonly perceived, it’s critical to focus on the liver’s ability to regulate cholesterol levels.
“If you have issues with cholesterol, it usually pertains to either the liver’s cholesterol production rate or its rate of clearance from the bloodstream,” emphasized Dr. Gabrielle Lyon, a board-certified family physician, to The Epoch Times.
However, various factors, including genetics, diet, lifestyle, and pre-existing health conditions, influence these mechanisms, making cholesterol management a complex matter, Lyon noted.
Instead of concentrating solely on lowering cholesterol levels, addressing the root causes is of utmost importance.
Ingesting cholesterol-rich foods does not lead to significant increases in blood cholesterol levels, as the liver adjusts its production accordingly. Nonetheless, dietary choices remain important, particularly in controlling inflammation. Persistent inflammation can hinder the liver’s capability to regulate cholesterol effectively, which is why an anti-inflammatory diet may aid in restoring balance.
Focus on the Underlying Issues
According to Duval, the following three strategies can significantly aid in addressing cholesterol imbalances.
1. Reduce Inflammation
Elevated inflammation prompts the liver to release additional LDL to repair damaged tissues. To mitigate systemic inflammation, follow an anti-inflammatory diet rich in omega-3 fatty acids (such as fatty fish and flaxseeds) and antioxidants (including berries, turmeric, and green tea), while eliminating foods that promote inflammation like refined sugars, trans fats, and highly processed items.
2. Improve Liver Function
Ensuring optimal liver function will enhance its ability to effectively regulate cholesterol levels.
- Milk thistle aids in liver detoxification and combats oxidative stress.
- Curcumin helps lower liver inflammation and fosters bile flow.
- N-acetylcysteine (NAC) increases glutathione, the liver’s primary antioxidant.
3. Maintain Healthy Lifestyle Habits
Monitoring cholesterol also requires engaging in physical activity and maintaining awareness of other lifestyle behaviors, including:
- Regular exercise to promote liver fat metabolism and boost HDL (good) cholesterol levels.
- Staying well-hydrated to support bile production and cholesterol elimination.
- Managing stress to lower cortisol levels, which can otherwise contribute to inflammation and disrupt cholesterol balance.
- Avoiding smoking to reduce oxidative stress and inflammation, both of which impact cholesterol levels.
- Maintaining an active lifestyle to support overall cardiovascular health and cholesterol management.
- Considering genetic predispositions, as they can influence cholesterol metabolism and necessitate a tailored management approach.
Instead of cutting out eggs and animal fats, a more balanced approach to dietary choices allows the body to naturally manage cholesterol levels. This involves prioritizing nutrient-dense foods while avoiding the excessive consumption of any single food group. Moreover, addressing core factors—such as inflammation and liver health—can enhance the body’s ability to manage cholesterol efficiently.
