Coconut Oil vs. Olive Oil: Which Is Better for Your Heart?

If you are choosing an everyday cooking oil with your heart in mind, olive oil is the better-supported choice. Its predominantly unsaturated fat fits heart-healthy dietary guidance, and extra virgin olive oil has been studied as part of a Mediterranean eating pattern associated with fewer major cardiovascular events. Coconut oil can add a distinctive flavor, but its high saturated-fat content makes it a less suitable default—especially when lowering LDL cholesterol is a priority.

That answer does not require treating coconut oil as a poison or olive oil as a medicine. The meaningful question is what you use regularly, how much you use, and what it replaces. Switching from a saturated-fat-rich cooking fat to an unsaturated oil is different from adding spoonfuls of any oil to an otherwise unchanged diet.

The American Heart Association recommends replacing saturated fats with unsaturated fats, including olive oil. Here is how that recommendation lines up with the research, what the competing claims get wrong, and how to make a practical choice without overcomplicating dinner.

The main difference is the type of fat

Coconut oil and olive oil are both concentrated sources of fat. Neither provides the fiber you would get from beans, oats, vegetables, or whole fruit. Their most important nutritional difference for this comparison is their fatty-acid composition.

According to Harvard’s Nutrition Source overview of coconut oil, roughly 80%–90% of coconut oil’s fat is saturated. One tablespoon supplies about 120 calories, 14 grams of total fat, and 12 grams of saturated fat. Exact label values vary, but this is not a small contribution of saturated fat.

Olive oil, by contrast, is predominantly monounsaturated fat. Extra virgin olive oil also retains plant compounds, including phenolic compounds, that help distinguish it from more refined versions. Mayo Clinic’s explanation of olive oil describes these characteristics and emphasizes using it in meals rather than drinking it as a supplement.

Saturated and unsaturated fats are not interchangeable in their effects on blood cholesterol. A diet high in saturated fat can raise LDL, often called “bad” cholesterol. Higher LDL contributes to cardiovascular risk. Replacing saturated fat with unsaturated options can improve the risk picture; simply replacing it with sugary or highly refined foods is not the same strategy.

One label claim can be particularly misleading: coconut oil contains no cholesterol. That is true, but the cholesterol in food and the LDL cholesterol circulating in your blood are not identical things. A cholesterol-free food can still contain substantial saturated fat and affect your LDL level.

What coconut-oil studies actually show

Most coconut-oil trials have measured blood lipids and other risk markers over relatively short periods. Those studies can help answer whether an oil changes cholesterol. They cannot, by themselves, establish whether using it for years prevents heart attacks or strokes.

The broader evidence raises concerns about LDL

A 2020 meta-analysis brought together 16 clinical trials comparing coconut oil with nontropical vegetable oils. As summarized in Harvard’s review of the analysis, coconut oil increased LDL by about 10 mg/dL on average compared with those oils. It also increased HDL, often called “good” cholesterol.

The comparison matters. The studies grouped several nontropical oils, including olive, canola, and sunflower oils. The result should not be presented as a precise prediction that every person switching specifically from olive oil to coconut oil will experience that LDL change. Individual responses, amounts, background diets, and trial methods differed.

Nevertheless, the overall finding supports caution about making coconut oil your main cooking fat. An earlier review of coconut consumption and cardiovascular risk factors similarly found that coconut oil generally raised LDL more than unsaturated plant oils, although often less than butter. Being better than butter on a particular measure does not automatically make it the best available choice.

One direct comparison did not find an LDL difference

You may have seen headlines about a 2018 randomized trial comparing coconut oil, olive oil, and butter. Participants were assigned 50 grams daily of one of the fats for four weeks. The study did not find a statistically significant difference in LDL change between the coconut-oil and olive-oil groups. Butter increased LDL more than either oil.

That is a real finding, not something to ignore. It also has limits. The trial was small and short, and participants knew which fat they were consuming. It involved adults aged 50–75 without known cardiovascular disease or diabetes who were not taking cholesterol-lowering medication. It did not measure heart attacks or strokes.

A study that fails to detect a difference is not necessarily proof that two oils are equivalent over the long term. The authors themselves stated that their findings did not change general recommendations to reduce saturated fat.

A newer review adds nuance, not proof of heart protection

A 2025 systematic review of virgin coconut oil included 14 randomized trials involving 1,049 adults. Interventions lasted between two and 24 weeks. Its pooled results found higher HDL and lower triglycerides, but no statistically significant overall change in other lipid markers or several other cardiometabolic measures.

This means it would be inaccurate to say every review finds that virgin coconut oil raises LDL under every study condition. It does not mean virgin coconut oil has been proved superior to olive oil, or that the observed HDL and triglyceride changes translate into fewer cardiovascular events. The authors called for larger, longer-term trials.

The practical interpretation is that coconut-oil results are not perfectly uniform, while the evidence still does not establish a reason to prefer it over an unsaturated oil for everyday heart health.

Why a higher HDL number does not settle the question

HDL is often described as “good cholesterol,” which can make any increase sound automatically protective. However, a favorable change in one laboratory marker does not prove that a food reduces heart attacks or cancels out an unfavorable change in another marker.

Coconut oil can raise HDL, as the studies above show. That observation should be reported accurately. But it should not be turned into the claim that its saturated fat no longer matters or that a higher LDL can be ignored.

For a personal decision, your clinician considers the broader lipid profile and cardiovascular risk rather than judging one food by its effect on HDL alone. The National Heart, Lung, and Blood Institute’s cholesterol-treatment guidance recommends an individualized plan that can include dietary changes, physical activity, and medication. An oil swap is one part of that plan, not a substitute for it.

Olive oil has stronger support within a heart-healthy eating pattern

Olive oil’s case rests on more than comparing its saturated-fat content with coconut oil’s. Extra virgin olive oil is a central component of Mediterranean dietary patterns that have been studied for cardiovascular outcomes.

In the corrected 2018 PREDIMED report, 7,447 older adults at high cardiovascular risk were assigned to a Mediterranean diet supplemented with extra virgin olive oil, a Mediterranean diet supplemented with nuts, or a comparison diet with advice to reduce fat. Over a median follow-up of 4.8 years, major cardiovascular events were less frequent in the Mediterranean-diet groups.

There are two important qualifications. First, the intervention was an eating pattern, not an isolated daily dose of olive oil. Participants received dietary education, and the pattern included foods such as vegetables, legumes, nuts, fruit, and fish. The trial was not a direct comparison of olive oil with coconut oil.

Second, the original report was withdrawn after problems with randomization procedures were identified. The corrected report used revised analyses, with broadly similar findings. Harvard’s explanation of the retraction and republication describes why the corrected version, rather than the original report, should inform interpretation.

The reasonable conclusion is that olive oil fits an evidence-supported dietary pattern. It is not reasonable to promise that adding olive oil to any diet will reproduce the trial’s results.

Extra virgin, refined, organic: which labels matter?

Extra virgin olive oil is a sensible first choice

Extra virgin olive oil is less refined and retains more of the olive’s characteristic flavor and plant compounds. Choose it when you enjoy its flavor in vegetables, beans, salads, and other meals. It is also the form supplied in the olive-oil arm of PREDIMED.

However, a more affordable olive oil can still be a useful way to replace saturated fat. You do not need the most expensive bottle to make a worthwhile change. The American Heart Association’s healthy-oil guidance includes olive oil alongside several other unsaturated oils; it does not require a premium specialty product.

“Light” olive oil should not be interpreted as permission to use unlimited amounts. Compare serving sizes and calories on the label rather than assuming that a lighter flavor means a low-calorie product.

Virgin coconut oil is still rich in saturated fat

Virgin coconut oil generally has a more noticeable coconut flavor than refined coconut oil. Processing can influence flavor, aroma, and performance in cooking, but it does not turn coconut oil into a predominantly unsaturated oil.

Likewise, “organic,” “cold-pressed,” and “plant-based” do not erase its saturated-fat content. Harvard’s coconut-oil guide also notes that “virgin” and “extra virgin” labeling for coconut oil does not carry the same regulated distinction as those terms do for olive oil. Read the nutrition panel rather than relying on the front of the jar.

Ordinary coconut oil is not the same as MCT oil

Some coconut-oil marketing borrows findings from research on specially formulated medium-chain triglyceride, or MCT, oils. Those products commonly concentrate particular fatty acids, especially caprylic and capric acids. Ordinary coconut oil has a different composition and contains substantial lauric acid.

As the Nutrition Reviews discussion of coconut oil and MCTs explains, their digestion and metabolism differ. Results from concentrated MCT formulations cannot simply be transferred to the coconut oil on your supermarket shelf. Nor does a claim about rapid energy use establish long-term heart protection.

Can you cook with olive oil?

Yes. Olive oil does not have to be reserved for cold salads. The American Heart Association lists healthy liquid oils as appropriate for cooking, baking, grilling, and roasting.

Use sensible heat management rather than treating smoke-point charts as a ranking of cardiovascular benefits. Different oils and products tolerate heat differently, and the temperature of a pan can rise quickly when it is empty. If an oil starts smoking, stop heating it and do not keep using the smoking oil. Choose an oil suited to the cooking method, and follow the product’s directions.

For routine sautéing and roasting, olive oil is a practical option. If you want a more neutral flavor, another unsaturated oil, such as canola, can also fit heart-healthy guidance. Coconut oil is not necessary simply because dinner involves a hot pan.

Store oils tightly closed in a cool, dark place rather than beside the stove. Buy a container you can reasonably finish, and discard oil that smells rancid. The AHA also advises against reusing cooking oil. Choosing a favorable fat does not make repeated deep-frying a heart-healthy cooking method.

Make the change a replacement, not an addition

The most useful switch is often simple: use an unsaturated oil where you previously used coconut oil, butter, or another saturated-fat-rich cooking fat. There is no need to begin drinking oil or add it to coffee for your heart.

Consider these everyday changes:

• For vegetables: use olive oil as the cooking fat instead of coconut oil, while keeping the vegetables—not the oil—the main component.
• For salads and beans: choose an olive-oil-based dressing instead of a cream-heavy topping, and keep the portion appropriate for the meal.
• For a neutral flavor: try canola or another suitable unsaturated oil rather than assuming coconut oil is the only alternative to butter.
• For baking: choose a preparation designed for liquid oil when possible. Replacing a solid fat can change texture, so a universal one-for-one substitution will not work in every bake.

The amount still matters. Olive oil is an energy-dense food, not a free ingredient. A measured pour helps you understand how much is going into a shared dish and how many portions the dish provides. There is no single tablespoon target that everyone needs to add to their day.

Look beyond the oil bottle as well. Oats, beans, lentils, vegetables, fruit, and whole grains contribute fiber that oils do not provide. A meal built around these foods, with an appropriate amount of unsaturated fat, is more useful than trying to improve an otherwise low-fiber diet with an oil supplement. Keep sodium in mind, too: changing the cooking fat does not reduce the salt in a packaged sauce or seasoning mix.

How much room is there for coconut oil?

You do not have to eliminate a culturally meaningful food or a flavor you enjoy to make olive oil your default. A small amount of coconut oil used occasionally for a particular flavor is different from using it for all cooking or taking it by the spoonful for supposed health benefits.

The relevant limit is your overall saturated-fat intake. The AHA recommends a pattern with less than 6% of calories from saturated fat, describing this as about 13 grams or less in a 2,000-calorie example. That calorie level is an illustration, not a prescription for everyone.

Against that example, the roughly 12 grams of saturated fat in a tablespoon of coconut oil accounts for most of the day’s allowance before considering cheese, meat, dairy, desserts, or other sources. This is why routine use can crowd out flexibility elsewhere in the diet.

If you have high LDL, existing cardiovascular disease, diabetes, or an inherited cholesterol disorder, ask your clinician or registered dietitian how to apply saturated-fat guidance to your situation. Do not stop or reduce a prescribed cholesterol medicine because you changed cooking oils. NHLBI emphasizes combining appropriate lifestyle changes with medication when prescribed.

Questions that often come up

Is coconut oil good for weight loss?

It is not a dependable weight-loss strategy. The 2020 trial meta-analysis summarized by Harvard’s Nutrition Source did not find a significant advantage over other vegetable oils for body weight, waist circumference, or body-fat percentage. Adding it to an unchanged diet also adds energy. Choose an oil for its role in meals, not a promise that it will burn belly fat.

Does a traditional coconut-rich diet prove coconut oil is harmless?

No single ingredient explains an entire population’s health. Traditional coconut-containing diets may also include fish, fruit, vegetables, and minimally processed foods, alongside very different activity and lifestyle patterns. Studies of coconut flesh or cream are not identical to studies of extracted oil. The review of coconut consumption in humans cautions against applying those observations directly to a different dietary setting.

If olive oil is too expensive, is coconut oil the next-best option?

Not necessarily. Canola, soybean, sunflower, and other nontropical liquid oils can provide unsaturated fats. The AHA’s shopping guidance suggests looking for oils with less than 4 grams of saturated fat per tablespoon and no partially hydrogenated oils. Compare local prices and labels; heart-conscious cooking does not require one premium oil.

Should I take olive-oil shots?

There is no need. Use olive oil as part of meals and as a replacement for less favorable fats. Mayo Clinic specifically advises incorporating it into food rather than drinking it as a supplement. More oil is not automatically more benefit.

The better everyday choice

For heart health, choose olive oil—particularly extra virgin when you like the flavor and it fits your budget—as your usual oil. Keep coconut oil as an occasional culinary choice rather than a cholesterol treatment or daily health supplement.

The strongest approach combines that choice with fiber-rich foods, sensible portions, sodium awareness, physical activity, and appropriate medical care. No oil can replace the rest of that pattern, but choosing an unsaturated one is a practical place to start.
