Walk into any natural grocery store and you’ll see it. Row after row of glass jars filled with that pearly white, semi-solid fat. People swear by it. They put it in their coffee, rub it on their faces, and fry their eggs in it. But then you talk to a cardiologist and they look at you like you’re drinking poison. So, is coconut oil good or is it just the world's most successful marketing campaign?
The answer isn't a simple yes or no. Honestly, it’s complicated.
For years, coconut oil was the darling of the wellness world. Proponents claimed it could kickstart your metabolism and even help with Alzheimer’s. Then, around 2017, the American Heart Association (AHA) dropped a hammer of a report. They basically said it’s high in saturated fat and therefore bad for your heart. Period. Since then, the health community has been split. You have the "keto" crowd on one side and traditional doctors on the other.
The Saturated Fat Debate: Not All Fats are Created Equal
Let’s get technical for a second. Most of the hate directed at coconut oil comes from its saturated fat content. We're talking about 82% to 90% saturated fat. That is higher than butter or lard. But here is where it gets interesting: the type of saturated fat matters.
Coconut oil is loaded with Medium-Chain Triglycerides (MCTs).
Most fats we eat are Long-Chain Triglycerides (LCTs). Your body processes them differently. LCTs go through the lymphatic system and can end up stored in your fat tissues. MCTs, specifically lauric acid, go straight to your liver. Your liver uses them for immediate energy or turns them into ketones. This is why people who follow a ketogenic diet are so obsessed with it. It’s quick fuel.
Dr. Marie-Pierre St-Onge at Columbia University has done some of the most famous research on MCTs. Her studies showed that MCTs can increase the rate at which people burn calories. But—and this is a big "but"—most of the coconut oil you buy in the store isn't 100% MCT oil. Pure MCT oil is a laboratory-refined version. Standard virgin coconut oil is only about 13% to 15% of the "true" weight-loss-inducing MCTs (like caprylic and capric acid).
The rest is lauric acid.

Lauric acid is weird. It acts like a hybrid. It has 12 carbon atoms, which puts it right on the edge of being a long-chain fat. It does raise your HDL (the "good" cholesterol), which sounds great. But it also raises your LDL (the "bad" cholesterol). Most cardiologists will tell you that raising your "good" cholesterol doesn't cancel out the risk of raising the "bad" kind.
Is Coconut Oil Good for Your Heart?
If you ask the AHA, they’ll point to dozens of studies showing that saturated fat increases the risk of cardiovascular disease. They recommend limiting saturated fat to about 5% or 6% of your daily calories. For a standard 2,000-calorie diet, that’s only about 13 grams.
One tablespoon of coconut oil has about 12 grams of saturated fat.
So, if you have one tablespoon, you've basically hit your limit for the day. Does that make it "bad"? Not necessarily. It makes it a "dose-dependent" food.
In places like Sri Lanka or the Philippines, people have eaten massive amounts of coconut for generations. They have historically low rates of heart disease. But researchers like Dr. Frank Sacks from Harvard point out that these populations aren't just eating the oil. They are eating the whole coconut—fiber, minerals, and all. Plus, their overall diets are usually way lower in processed sugar and flour than the typical Western diet. Context is everything.
You can't eat a double cheeseburger and then add a "healthy" tablespoon of coconut oil to your coffee and expect a miracle. That’s just adding more fat to an already inflammatory meal.
Skin, Hair, and the "Glow" Factor
If there is one area where almost everyone agrees is coconut oil good, it’s topical use. You don't have to eat it to get the benefits.

Coconut oil is a fantastic occlusive. That’s just a fancy way of saying it creates a barrier on the skin to lock in moisture. If you have eczema or chronically dry skin, it’s a lifesaver. It contains monolaurin, which has antimicrobial properties. A study published in the journal Dermatitis found that virgin coconut oil was actually more effective than mineral oil in treating atopic dermatitis.
It’s also one of the few oils that can actually penetrate the hair shaft. Most oils just sit on top of your hair and make it look greasy. Coconut oil gets inside. It reduces protein loss during washing. If you have fine hair, though, be careful. It can be too heavy and lead to "protein buildup," making your hair feel brittle rather than soft.
- For skin: Best for body, not face (it can clog pores and cause acne for some).
- For hair: Great as a pre-wash mask.
- For teeth: Oil pulling. People swear it whitens teeth, but the evidence is mostly anecdotal. It does, however, reduce bacteria in the mouth.
The Smoke Point Myth
Chefs often argue about what oil to use for high-heat cooking. You've probably heard that olive oil is bad for frying because it has a low smoke point.
Refined coconut oil has a smoke point of about 400°F (204°C).
Virgin (unrefined) coconut oil is lower, around 350°F (177°C).
It is incredibly stable. Because it is saturated, it doesn't oxidize as easily as polyunsaturated vegetable oils (like soybean or corn oil) when heated. Oxidized oils create free radicals, which are definitely not "good." So, if you are sautéing veggies at a medium temperature, coconut oil is a very safe choice. It won't go rancid in the pan.
Metabolism and Brain Health: The Real Hype
The "bulletproof" coffee craze started because of the claim that coconut oil boosts brain function. This idea stems from research into ketones as an alternative fuel source for the brain.

In people with early-stage Alzheimer’s or mild cognitive impairment, the brain sometimes struggles to use glucose for energy. Ketones can bypass that problem. However, most of the "miracle" stories you read online involve people taking high-dose, pharmaceutical-grade MCT oil, not just a spoonful of the stuff from the grocery store.
Is it a brain booster for a healthy 25-year-old? The evidence is thin. Most of the energy boost people feel is likely just the fat slowing down the absorption of caffeine, which prevents the "jitters" and the "crash."
Choosing the Right Jar
If you're going to use it, you need to know what to buy. The labels are confusing.
- Virgin Coconut Oil: This is the gold standard. It's made from fresh coconut meat. No chemicals used. It smells and tastes like coconut.
- Refined (RBD) Coconut Oil: RBD stands for Refined, Bleached, and Deodorized. It’s made from "copra" (dried coconut). It has no flavor or smell. It’s fine for cooking, but you lose some of the antioxidant polyphenols found in the virgin version.
- Fractionated Coconut Oil: This is coconut oil that has been processed to remove the lauric acid. It stays liquid even in the fridge. This is basically pure MCT oil. Great for skin or supplements, but not really a "whole food" anymore.
Stay away from "hydrogenated" coconut oil. That creates trans fats. Trans fats are universally accepted as terrible for your health. Avoid them at all costs.
Actionable Steps for Using Coconut Oil
Stop looking for a "superfood" miracle. It doesn't exist. Coconut oil is a tool in your kitchen and bathroom, not a magic potion.
If you want to incorporate it properly, do this:
- Swap, don't add. If you want to cook with coconut oil, use it instead of butter or lard, not in addition to them.
- Check your labs. If you decide to start the "keto coffee" routine, get your blood work done after three months. Some people are "hyper-responders" to saturated fat, and their LDL will skyrocket. If that’s you, stop.
- Use it for high-heat sautéing. It’s much more stable than grapeseed or canola oil for quick stir-frys.
- Prioritize virgin versions. You want those polyphenols. They help mitigate some of the inflammatory effects of the fat.
- Keep it on your nightstand. It is one of the cheapest, most effective body moisturizers on the planet.
The bottom line? Coconut oil isn't the villain it was made out to be in 2017, but it’s not the panacea people claimed in 2012. It’s a calorie-dense fat with some unique metabolic properties and excellent topical benefits. Use it sparingly in your food and liberally on your skin.
