A perfect example of a healthy food that was unfairly demonized in the past is coconut oil.
It has mainly gotten a bad rap because it is very high in saturated fat.
But as we know, saturated fat is not so bad and what we’re left with is a perfectly healthy cooking oil.
Coconut Oil Got a Bad Rap in The Past
Coconut oil is one of the richest sources of saturated fat you can find, with around 90% of calories as saturated fat.
Saturated fat was unfairly demonized a few decades ago by a few biased but highly influential scientists. However, new studies show that there is no association between saturated fat and heart disease (1, 2, 3).
The initial studies on coconut oil that supposedly demonstrated that it was unhealthy used refined and hydrogenated coconut oil that contained trans fats.
These studies have no relevance to the unrefined, organic, virgin coconut oil that is commonly found in health food stores today… which is the subject of this article.
Populations That Eat a LOT of Coconut Are Healthy
If coconut fat were bad for you, then we should see some very sick people in populations that eat a lot of it.
But we don’t. Populations who eat a large percentage of calories from coconuts are MUCH healthier than Western nations.
Bottom Line: Populations that eat a lot of coconut are in excellent health.
Coconut Oil Has a Unique Composition of Fatty Acids
Coconut oil is very different from most other cooking oils and contains a unique composition of fatty acids.
The fatty acids are about 90% saturated.
This makes coconut oil highly resistant to oxidation at high heats. For this reason, it is the perfect oil for high-heat cooking methods like frying (6).
These fatty acids go straight from the digestive tract to the liver, where they are likely to be turned into ketone bodies and provide a quick source of energy.
Bottom Line: Coconut oil is rich in saturated medium chain fatty acids. They are resistant to high heat and can easily turn into ketone bodies in the liver.
Coconut Oil is Rich in Lauric Acid
The most abundant fatty acid in coconut oil is the 12-carbon Lauric Acid, which is broken down into a compound called monolaurin in the body.
Lauric acid and monolaurin are both very interesting due to the fact that they can kill microbes like bacteria, fungi and viruses.
Bottom Line: The main fatty acid in coconut is an efficient killer of pathogens.
Coconut Oil, Blood Lipids and Cardiovascular Disease
Unrefined coconut oil actually improves blood lipid profiles.
In two separate rat studies, virgin coconut oil was compared against copra oil (refined coconut oil) and corn oil.
The virgin coconut oil significantly reduced Total and LDL cholesterol, oxidized LDL, triglycerides and increased HDL (the good) cholesterol (12).
It also had favorable effects on blood coagulation factors and antioxidant status (13).
In a study of women with abdominal obesity, coconut oil increased HDL and lowered the LDL:HDL ratio, while soybean oil increased Total and LDL cholesterol and decreased HDL (14).
Medium chain triglycerides (the fats in coconut oil) have also been shown to reduce blood triglycerides compared to long chain fats (15).
Coconut oil may be protective against heart disease, not the other way around.
Bottom Line: Coconut oil improves blood lipids in both animals and humans.
Coconut Oil Can Help You Lose Weight
There is considerable evidence that coconut oil can help you lose weight.
In a study of 40 women with abdominal obesity, coconut oil reduced waist circumference compared to soybean oil (14) while also improving health markers (see above).
Medium chain triglycerides have also been consistently shown to promote weight loss in both animal and human studies:
- They increase energy expenditure compared to long chain fats (16).
- They lead to greater satiety (17, 18).
- They lead to a greater proportion of the weight lost come from fat, indicating that they may be muscle sparing (19).
Substituting other calorie sources for coconut oil is likely to help you lose weight.
Bottom Line: The fatty acids in coconut oil can increase energy expenditure, improve satiety and help you lose weight.
Coconut Oil Has Other Amazing Health Benefits
Like I mentioned above, coconut oil is likely to turn into ketone bodies in the liver (20).
Ketone bodies can provide energy for the brain. They are particularly useful against epilepsy and may also improve various other disorders.
To top it all off, coconut oil goes with almost any food and tastes awesome.
