Olive oil is the better choice for overall health, and the evidence isn’t particularly close. While coconut oil has been marketed as a superfood, the bulk of clinical research favors olive oil for heart health, inflammation, and long-term disease prevention. That said, coconut oil isn’t the villain it’s sometimes made out to be, and the full picture is more nuanced than a simple good-versus-bad comparison.
What’s Actually in Each Oil
The biggest difference between these two oils is their fat composition. Coconut oil is roughly 82% saturated fat, making it one of the most saturated cooking fats available. Olive oil, by contrast, is about 73% monounsaturated fat (primarily oleic acid) with only around 14% saturated fat. This distinction drives most of the differences in how each oil affects your body.
Extra virgin olive oil also contains a class of protective plant compounds that coconut oil simply doesn’t have. These include hydroxytyrosol and oleocanthal, both of which act as antioxidants and reduce inflammation. Oleocanthal works on the same inflammatory pathway as ibuprofen, which is one reason olive oil has such strong ties to cardiovascular protection. The higher the quality of extra virgin olive oil, the more of these compounds it contains.
How Each Oil Affects Your Cholesterol
This is where the debate gets interesting. A well-designed trial published in BMJ Open compared coconut oil, olive oil, and butter head-to-head in healthy adults over four weeks. The result: coconut oil and olive oil produced no significant difference in LDL cholesterol (the “bad” kind). Butter raised LDL substantially compared to both oils. Coconut oil did raise HDL cholesterol (the “good” kind) more than olive oil, by about 6 mg/dL.
However, a larger meta-analysis published in the American Heart Association’s journal Circulation told a less favorable story for coconut oil. When pooling 16 clinical trials, coconut oil raised LDL cholesterol by about 10.5 mg/dL compared to other plant-based oils like olive, soybean, and canola. It also raised HDL by about 4 mg/dL and total cholesterol by nearly 15 mg/dL. So coconut oil boosts both good and bad cholesterol, while olive oil tends to improve the ratio between the two.
The practical takeaway: if you’re replacing butter or lard with coconut oil, your cholesterol profile will likely improve. If you’re replacing olive oil with coconut oil, it will likely get worse.
Heart Disease Prevention
Olive oil has something coconut oil lacks entirely: large-scale evidence showing it prevents heart attacks and strokes. The landmark PREDIMED trial, which followed thousands of people eating a Mediterranean diet supplemented with extra virgin olive oil, found a roughly 30% reduction in cardiovascular events compared to a control diet. No comparable long-term trial exists for coconut oil.
The American Heart Association’s 2026 dietary guidance statement groups coconut oil with animal fats and other tropical oils, recommending that people use nontropical plant oils like olive, canola, and soybean oil in their place. This position is based on coconut oil’s high saturated fat content and the absence of evidence showing cardiovascular benefit.
The protective compounds in olive oil go beyond just fat composition. Its polyphenols inhibit enzymes involved in inflammation and appear to protect blood vessel walls from the kind of damage that leads to plaque buildup. These effects have been documented in both lab studies and human trials, giving olive oil a biological advantage that its fat profile alone doesn’t fully explain.
How Lauric Acid Changes the Picture Slightly
About half the saturated fat in coconut oil is lauric acid, a medium-chain fatty acid that behaves differently from the saturated fats in red meat and butter. In liver cells, lauric acid activates a metabolic pathway that increases fat burning and reduces the secretion of certain cholesterol-carrying particles. This is one reason coconut oil doesn’t raise LDL as dramatically as its saturated fat content would predict.
Oleic acid, the primary fat in olive oil, works through a different mechanism. It tends to increase the secretion of LDL-carrying particles from the liver, but it also shifts the overall balance of blood lipids in a favorable direction by lowering total-to-HDL cholesterol ratios. In practice, the net effect of oleic acid on cardiovascular risk is consistently beneficial, while the net effect of lauric acid is still debated.
Cooking Performance
One common argument for coconut oil is that it’s more stable at high heat. This is partly true: coconut oil’s saturated fat structure makes it resistant to oxidation. But the idea that olive oil can’t handle cooking temperatures is a myth that won’t die.
High-quality extra virgin olive oil has a smoke point around 374 to 405°F, which comfortably covers sautéing, roasting, and most pan-frying. Virgin olive oil reaches about 410°F. Those polyphenols in extra virgin olive oil actually serve as natural antioxidants during cooking, slowing the formation of harmful breakdown compounds. Research shows that olive oils with higher polyphenol content produce fewer polar compounds (a marker of oil degradation) when heated, and they maintain stability longer.
Extended deep frying at 170°C (338°F) does degrade about half of olive oil’s polyphenols over three hours, but typical home cooking involves much shorter exposure times. For anything other than prolonged deep frying, extra virgin olive oil performs well and retains meaningful amounts of its protective compounds.
Coconut oil does have practical advantages in certain recipes. Its solid texture at room temperature makes it useful in baking as a butter substitute, and its mild sweetness works well in curries and certain desserts. These are legitimate reasons to keep it in your kitchen, just not health reasons.
The Bottom Line on Daily Use
If you’re choosing one oil as your everyday cooking fat, olive oil is the stronger choice by a wide margin. It lowers cardiovascular risk, delivers anti-inflammatory compounds, handles heat well, and has decades of large-scale human evidence behind it. Coconut oil isn’t harmful in modest amounts, especially as a replacement for butter or highly processed fats, but it doesn’t offer the same protective benefits. Using coconut oil occasionally for flavor or texture is perfectly reasonable. Building your diet around it instead of olive oil means giving up well-documented health advantages for benefits that remain largely theoretical.
