In 2018, Dr. Karin Michels, a Harvard epidemiology professor, stirred a global debate by labeling coconut oil as “poison” in a viral lecture.
Her claims, which positioned coconut oil as worse than lard, shocked many health enthusiasts and professionals alike. But is coconut oil truly harmful, or is it misunderstood? As a nutritionist or dietitian, I aim to clarify the facts about coconut oil and its place in a balanced diet.
What Was Said About Coconut Oil?
Dr. Michels’ claims were centered on three points:
- Coconut oil contains saturated fats that clog arteries.
- It raises LDL (bad cholesterol) without offering health benefits.
- Alternatives like rapeseed, sunflower, and canola oils are healthier options.
While these assertions sound alarming, they overlook nuances that a professional nutritionist or dietitian would consider. Let’s explore the science behind coconut oil.
Coconut Oil’s Composition and Saturated Fats
Coconut oil is approximately 80% saturated fat, primarily in the form of medium-chain triglycerides (MCTs). Unlike long-chain fats found in many other oils, MCTs are metabolized rapidly, providing energy rather than being stored as fat.
The standout MCT in coconut oil is lauric acid, which comprises about 50% of its fatty acids. Lauric acid has antimicrobial and anti-inflammatory properties, making it beneficial for gut health and immunity.
Dietitian Insight: While coconut oil’s saturated fats may seem concerning, modern research suggests that saturated fats, when consumed in moderation, can have a neutral or even positive impact on heart health.
Does Coconut Oil Clog Arteries?
A common criticism of coconut oil is its potential to raise LDL cholesterol. However, it also increases HDL (good cholesterol), which may help balance the lipid profile.
No conclusive evidence directly links moderate consumption of coconut oil to an increased risk of heart disease. Instead, overall diet quality and lifestyle factors play a larger role in cardiovascular health.
Nutritionist Tip: Combine coconut oil with other heart-healthy fats, such as olive oil and fatty fish, to maintain a balanced approach.
Comparing Coconut Oil to Other Cooking Oils
Dr. Michels suggested oils like rapeseed, sunflower, soybean, and canola as superior alternatives. While these oils contain polyunsaturated fats (PUFAs) known for heart health, they are often highly processed, which introduces several concerns:
- Refining Process: Chemical solvents used in refining may leave harmful residues.
- Oxidation Risk: PUFAs are unstable at high heat, leading to the formation of free radicals that promote inflammation.
- Trans Fats: Small amounts of trans fats in some refined oils are linked to heart disease.
Virgin coconut oil, in contrast, is minimally processed, stable at high temperatures, and free of trans fats, making it a reliable option for certain cooking methods.

Coconut Oil vs. Lard
Dr. Michels also compared coconut oil to lard, suggesting the latter as a better option. While lard has a better omega-6 to omega-3 ratio, it is not ideal for high-heat cooking due to its lower smoking point. Coconut oil, with its stability and absence of trans fats, may be preferable for frying and sautéing.
Health Benefits of Coconut Oil
Although coconut oil isn’t a miracle food, it does offer several noteworthy health benefits:
Boosts Metabolism: Coconut oil is thermogenic, helping the body burn calories more efficiently.
Supports Gut Health: Lauric acid’s antimicrobial properties combat harmful bacteria and promote gut microbiota balance.
Increases HDL Cholesterol: Raising good cholesterol may benefit heart health.
Cooking Stability: Its high smoking point makes it ideal for high-heat cooking.
Appetite Regulation: Coconut oil stimulates hormones like leptin, which promote satiety and appetite control.
Is Coconut Oil Really Poison?
Labeling coconut oil as “poison” oversimplifies its role in nutrition. While it is high in saturated fats, its unique composition, including MCTs and lauric acid, provides health benefits when consumed responsibly.
The real focus should be on reducing harmful fats, such as trans fats and hydrogenated oils, which are universally recognized as unhealthy.
A Balanced Approach to Coconut Oil
In nutrition, there are no one-size-fits-all answers. Coconut oil is neither a superfood nor a poison; it’s a versatile cooking oil that can be part of a balanced diet.
Nutritionist Recommendations:
- Use coconut oil for high-heat cooking, such as frying or baking.
- Incorporate other healthy fats, like olive oil, avocado, nuts, seeds, and fatty fish, for a well-rounded diet.
- Consume coconut oil in moderation to avoid excess calorie and fat intake.
Conclusion: What Dietitians Say About Coconut Oil
The controversy surrounding coconut oil underscores the importance of nuanced, evidence-based guidance. While it may not suit everyone, it can be a valuable addition to a healthy lifestyle when used thoughtfully.
As a nutritionist or dietitian, my advice is to focus on overall dietary patterns rather than fixating on a single ingredient. Pairing coconut oil with other nutrient-dense foods ensures a balanced approach to health and wellness.
Misinformation can easily cloud judgment, so always rely on trusted sources and consult professionals for personalized advice. Coconut oil isn’t poison—it’s simply another tool in the toolkit for building a wholesome, balanced diet.
