Coconut oil is not clearly healthier than butter, and neither is a great choice if heart health is your priority. Both are high in saturated fat, though coconut oil contains roughly 50% more of it per tablespoon. The meaningful differences between them come down to how each one affects your cholesterol and what you’re using them for in the kitchen.
Saturated Fat: Coconut Oil Has More
A tablespoon of coconut oil contains about 11.2 grams of saturated fat. The same amount of butter has 7.2 grams. That’s a significant gap, and it surprises most people who think of coconut oil as the “healthier” option. Almost all of coconut oil’s fat is saturated, leaving very little room for the unsaturated fats your body actually benefits from.
Butter, while still high in saturated fat, has a more varied fat profile. It delivers about 3.3 grams of monounsaturated fat per tablespoon (the type found in olive oil and avocados), compared to less than 1 gram in coconut oil. Neither provides much polyunsaturated fat, the kind found in fish and flaxseed.
How Each One Affects Your Cholesterol
Here’s where things get interesting. Despite having more saturated fat, coconut oil doesn’t perform worse than butter in cholesterol studies. A randomized trial published in BMJ Open found that butter raised LDL (“bad”) cholesterol significantly more than coconut oil did. Coconut oil also raised HDL (“good”) cholesterol more than butter. Overall, butter worsened the ratio of total cholesterol to HDL cholesterol, a key marker for heart disease risk, while coconut oil did not.
That said, coconut oil is no health food by this measure either. A meta-analysis in the American Heart Association journal Circulation, pooling data from 16 clinical trials, found that coconut oil raised LDL cholesterol by about 8.6% and HDL cholesterol by about 7.8% compared to plant oils like olive, canola, and soybean oil. So coconut oil looks better than butter in head-to-head comparisons, but it looks worse than the oils most nutrition experts recommend.
The MCT Claim Is Misleading
Much of coconut oil’s health reputation rests on the idea that it’s rich in medium-chain triglycerides, or MCTs. These are fats that your body processes more quickly than typical dietary fats, using them for energy rather than storing them. Pure MCT oil has shown some metabolic benefits in research.
The problem is that coconut oil isn’t really an MCT oil. About 42% of its fat comes from lauric acid, which is technically classified as a medium-chain fat based on its molecular length. But lauric acid is digested and absorbed much more slowly than true MCTs, behaving more like a long-chain fat in your body. The genuinely fast-metabolizing MCTs in coconut oil (caprylic and capric acid) make up only about 12% of its total fat. So the metabolic advantages people associate with MCT oil don’t translate well to coconut oil as you’d actually use it in cooking.
What Heart Health Guidelines Say
The American Heart Association’s most recent dietary guidance groups coconut oil with butter and other animal fats, not with plant oils. Their recommendation is straightforward: for heart-healthy eating, use nontropical plant oils (olive, canola, soybean) in place of both animal fats and tropical oils like coconut. The evidence that swapping butter for unsaturated plant oils lowers LDL cholesterol is strong, and the same applies to replacing coconut oil with those same plant oils.
This doesn’t mean you need to eliminate either fat entirely. It means that if you’re choosing between coconut oil and butter specifically for health reasons, you’re comparing two options that both fall into the “use sparingly” category. The bigger win is using olive oil or another unsaturated oil when you can.
Where Each One Works in the Kitchen
If you’re choosing based on cooking performance, there are real differences. Refined coconut oil has a smoke point of about 400°F (204°C), making it suitable for sautéing and moderate-heat frying. Virgin (unrefined) coconut oil smokes at a lower 350°F (177°C). Regular butter has a low smoke point of just 302°F (150°C), which is why it burns easily in a hot pan. Clarified butter, or ghee, jumps to around 482°F (250°C) because the milk solids that burn at low temperatures have been removed.
Flavor is the other practical difference. Butter adds richness and a familiar savory quality to baked goods, sauces, and vegetables. Virgin coconut oil has a mild coconut flavor that works well in some baking, curries, and stir-fries but can be unwelcome in savory dishes where you don’t want that sweetness. Refined coconut oil is essentially flavorless.
The Bottom Line on the Swap
Replacing butter with coconut oil gives you a modest improvement in cholesterol ratios based on the available trial data. But it also increases your total saturated fat intake. If your goal is cardiovascular health, the more impactful change is replacing either one with olive oil, avocado oil, or canola oil when the recipe allows it. For the dishes where you genuinely need a solid fat (pie crust, certain baking, spreading on toast), choosing between coconut oil and butter is more about taste and cooking needs than a meaningful health distinction.
