Coconut Oil: Nutrition Profile and Potential Health Effects

Coconut oil is a popular form of cooking oil, but whether it’s a healthy choice tends to be a topic that creates confusion.

This is largely because some people overpraise coconut oil’s heat stability, while others completely dismiss it over its high saturated fat content.

In this article, we’ll assess the potential health effects of coconut oil based on the latest scientific research.

We’ll let you know its potential benefits and drawbacks, while also examining its smoke point, oxidative stability, full nutritional profile, and what it all means for you.

Potential Health Effects

In this section, we’ll look at some of the potential health effects of coconut oil based on recent findings from scientific studies.

Heart Health

Since coconut oil is approximately 83% saturated fat by weight, organizations like the American Heart Association have warned to limit it.

This is because high intakes of saturated fat can raise “bad” LDL cholesterol levels, which are associated with a greater risk of developing cardiovascular disease.

However, findings from studies (and particularly press headlines covering these findings) can be confusing.

Let’s start by looking at some key headline findings from recent studies:

• A 2025 systematic review of 14 randomized trials found that virgin coconut oil “improved” triglyceride and HDL cholesterol levels. However, no significant differences were seen in health markers like LDL cholesterol or blood pressure.
• However, an earlier 2023 systematic review of 8 studies found that coconut oil intake “substantially increased LDL.”

Impact on Weight Management

You may have seen claims that coconut oil can be useful for weight loss, but is there any truth to this?

The truth: No, not really.

This idea comes from coconut oil’s high content of medium-chain triglycerides (MCTs). MCTs are types of fatty acids (fat) found in coconut oil that include caprylic acid.

In contrast to most fats, the digestion of MCTs is rapid and has been described as “5–8 times faster,” allowing their use as a more immediate energy source. Based on this, some have theorized that fats with high MCT content, like coconut oil, are less likely to contribute to fat gain.

However, coconut oil isn’t pure MCT oil and contains a wide range of fatty acids that act in different ways. Furthermore, there is a lot of available research on this topic, and the data doesn’t lie.

A 2025 systematic review investigated the dose-response effect of coconut oil supplementation on body weight. Based on findings from 15 clinical trials involving 620 participants, the review found coconut oil had the following effects on:

• Waist circumference: Coconut oil supplementation led to no significant effect on waist circumference.
• Weight and BMI: While there was a very slight effect on weight and body mass index (BMI), they were not meaningful. For example, the mean weight loss observed was only 0.04 kg (40 grams).

Adding isolated fats to the diet from coconut oil is unlikely to be a helpful choice for weight management.

Smoke Point and Oxidative Stability

Let’s now look at coconut oil’s value for high-heat cooking by assessing its smoke point and oxidative stability.

Smoke point is the temperature where a cooking fat starts breaking down (degrading), at which point it starts to smoke (burn). As this happens, it generates compounds like acrolein that contribute to that “burnt” flavor.

However, just because an oil has a high smoke point doesn’t necessarily mean it has optimal stability at high temperatures.

Oxidative stability is how stable a cooking fat is when exposed to heat, light, and oxygen. Oils with lower oxidative stability generate more oxidation products like polar compounds.

It is thought that these oxidation products may have potentially negative effects on human health. However, there is a lack of conclusive evidence at this stage, and research is ongoing. While intake of deep-fried foods has long been linked to an increased risk of cardiovascular disease, further large, high-quality studies are necessary to confirm this.

How This Relates to Coconut Oil

Firstly, refined coconut oil has a relatively high smoke point of approximately 200°C (392°F). Virgin (first-press) coconut oil, which contains higher levels of polyphenols and other compounds, has a smoke point of around 177°C (350°F).

While these smoke points are not the highest compared to other common oils, they are generally suitable for medium-heat cooking at home – especially in the case of refined coconut oil.

However, oxidative stability is one of coconut oil’s biggest positives:

• A study published in 2023 investigated the oxidative stability of coconut oil, fish oil, palm oil, rice bran oil, and sunflower oil. Coconut oil had a significantly higher oxidative stability and induction time (time until it breaks down) than the other oils tested.
• A 2018 study assessed the oxidative stability of common cooking oils including coconut oil, olive oil, canola oil, soybean oil, and more. They did this by testing how the oil held up to the impact of prolonged, high-heat cooking. Among all the oils, coconut oil had the highest oxidative stability and developed the lowest amount of polar compounds.

As these studies show, coconut oil is likely one of the most heat-stable commercially available cooking oils. Learn more about the best cooking fats for deep-frying here.

Coconut Oil and Brain Health

In conditions like Alzheimer’s disease, the brain’s ability to use glucose is impaired. Due to this, there has been research into the potentially positive effects of MCT oils for cognitive health.

As mentioned earlier, this is because MCT oils are quickly absorbed. This leads to the generation of ketones, a type of molecule formed from dietary fats, similar to how glucose comes from carbohydrates. Ketones are an “alternate fuel source” to glucose and can be used for energy.

Since coconut oil contains MCTs, this research has extended to coconut oil too.

However, at this point, there appears to be a lack of strong evidence to suggest coconut oil has benefits in this area:

For example, a 2024 systematic review assessed the effect of coconut oil on Alzheimer’s disease and broader dementia. While this review found slight improvements in cognitive testing scores, it was based on findings from only four small studies.

Other Recent Research on Coconut Oil

• Appetite: Two recent randomized controlled trials available here and here found that coconut oil led to slightly higher ratings of fullness compared to olive oil. However, these studies were small, including only 10 and 20 people, respectively.
• Blood sugar and insulin sensitivity: A 2022 systematic review of 18 human interventional trials found that long-term coconut fat intake (from oil or coconut products) was associated with increased insulin resistance. Additionally, reduced insulin responses to meals containing coconut fat were observed, resulting in slightly increased blood sugar levels.

Nutritional Profile of Coconut Oil

Now that we know a little more about the potential health effects of coconut oil, let’s review the nutrients it provides.

The following tables show the full nutritional values of coconut oil per 100g and per 13.6g tablespoon serving.

Nutritional data has been sourced from the USDA’s FoodData Central. We have calculated percent daily values (% DV) using this data, and they are based on a 2,000 calorie diet.

Calories and Macronutrients

Nutrient	Per 100g (% DV)	Per 13.6g tablespoon (% DV)
Calories	892 kcal	121 kcal
Carbohydrates	0g (0%)	0g (0%)
Fiber	0g (0%)	0g (0%)
Sugars	0g	0g
Fat	99.1g (127%)	13.5g (17%)
Saturated fat	82.5g (413%)	11.2g (56%)
Monounsaturated fat	6.33g	0.86g
Polyunsaturated fat	1.7g	0.23g
Omega-3	0.02g	0g
Omega-6	1.68g	0.23g
Protein	0g (0%)	0g (0%)
Cholesterol	0g (0%)	0g (0%)

As the table shows, coconut oil is primarily a source of saturated fat. Like all cooking fats, it contains no carbohydrates or protein.

Vitamins and Minerals

According to USDA data, coconut oil contains trace amounts of the following vitamins and minerals:

• Calcium: 1 mg per 100g
• Iron: 0.05 mg per 100g
• Zinc: 0.02 mg per 100g
• Choline: 0.3 mg per 100g
• Vitamin E: 0.11 mg per 100g
• Vitamin K: 0.6 mcg per 100g

However, none of these essential nutrients are present in meaningful amounts. All are below 1% of the daily value per 100 grams, and a typical tablespoon serving would provide almost zero.

Is Coconut Oil a Good Choice?

Now that we know some of the potential benefits and drawbacks, is coconut oil a good choice of cooking oil?

As always, the answer depends on context, dose, and overall diet.

Reasons to Use Coconut Oil

• Flavor: You like the taste.
• Heat stability: You want to use a cooking oil that’s less likely to form significant amounts of oxidation products like polar compounds.
• Smoke point: You want to use a cooking oil that has a relatively high smoke point (note: this applies more to refined coconut oil than virgin oil).

Reasons to Consider Alternatives

• Managing cholesterol levels: Since coconut oil is high in saturated fat, it is more likely to raise LDL cholesterol levels compared to unsaturated oils. Note: Individuals requiring personal health advice on this topic should consult with their healthcare provider before making dietary changes.
• The price: Coconut oil tends to be a little more expensive than more common oils like canola oil.

The Verdict

For those who enjoy using coconut oil, there is no reason why it can’t be part of a health-promoting diet.

However, just be aware that it can potentially raise LDL cholesterol levels compared to other oils.

For this reason, it is important to consider how it fits in with your overall diet and dietary guidelines. Additionally, using a tablespoon of coconut oil in a dish for four people is quite different to one person consuming a tablespoon.

Aside from this, coconut oil offers good stability and is widely recognized as a stable choice for higher-heat cooking.
