There’s One Factor that determines whether Coconut Oil will Help or Harm Us.

The American Heart Association (AHA) recently released a statement advising against the use of coconut oil, and the internet went bonkers.

And for good reason, I suppose…

After an exhaustive meta-analysis of many different studies on saturated fats and the risk of cardiovascular concerns, the AHA is strongly advising the public to lower their intake of saturated fats, like coconut oil, and replace them with polyunsaturated fatty acids (PUFAs) to lower the incidence of cardiovascular disease.

An Explanation.

The AHA is making suggestions based on what the average American eats and the resultant pitfalls of that diet.

As a result of decades of overeating sugar and processed foods, we have slowly compromised our digestive strength. The epicenter of this digestive demise is the liver and gallbladder. Today, the number one elective abdominal surgery is gallbladder removal surgery. (1)

If we continue to eat the Standard American Diet (SAD)—which is loaded with processed food and sugar and low on fiber—then, yes, adding a saturated fat like butter, ghee, or coconut oil would not be beneficial.

The Dangers of Polyunsaturated Fatty Acids.

The reason processed foods stay “good” for so long is the addition of bleached, boiled, and deodorized vegetable oils, called polyunsaturated fatty acids or PUFAs.

PUFAs are highly indigestible and are linked to a host of health concerns including high blood sugar, belly fat, high blood pressure, and triglyceride and cholesterol-related concerns. (2)

Many of these health concerns have been correlated with a lack of bile production or congestion in the bile ducts or gallbladder. Gallbladder congestion and poor bile flow are also linked to reduced digestive strength and difficulty processing dietary fats like coconut oil.

When one eats a diet high in sugar and low in fiber, the ability to digest saturated fats becomes more difficult. Fiber is required to escort bile and unwanted fat to the toilet. Fiber also maintains a healthy gut microbiome. When we combine a diet high in sugar and processed foods with a diet high in saturated fats, which are another fuel supply for the body, we can easily overshoot the body’s energy needs.

The extra unused fuel will be deposited as fat around the belly, in the arteries, the lymph and the rest of the body. (2)

Coconut Oil’s Effect on Cholesterol.

In their studies, here’s what the AHA found about coconut oil and butter: (8)

The good: Lowered triglyceride levels. This is great, as high triglycerides are an independent risk factor for heart disease. Increased HDL levels—which are considered to be the “good” cholesterol particles.

The okay: Increased overall cholesterol levels. This is not a major concern, as cholesterol was removed as a primary risk factor for heart concerns.

The bad: Increased LDL levels—which are considered the “bad” cholesterol particles. Not good. When LDL levels increase due to oxidation and/or damage from processed foods and excess sugar in the diet, they become damaging to the cardiovascular system. (4,5)

The Shortcomings of the Studies.

In most of these studies, the researchers used safflower oil as the polyunsaturated fatty acid to compare to coconut oil. Safflower oil is well-known to reduce cholesterol levels. (3)

The consumption of highly omega-6, refined polyunsaturated fatty acids has also, however, been linked to increased risk of heart health concerns.

Vegetables oils, such as canola, soy, sunflower, corn, grapeseed, safflower, rice bran, cottonseed oiland, of course, those fake butter spreads like margarine, are all rich in omega-6 polyunsaturated fatty acids.

Our intake of these PUFAs has significantly increased in recent decades. Studies have shown a shift away from the intake of omega-3 (fish oil) fatty acids to the intake of more highly processed omega-6 (vegetable oil) fatty acids.

Historically, humans ate more omega-3s than omega-6s. Since this dramatic shift, there has been an associated increase in obesity, blood sugar, and heart health concerns. (10)

While an exhaustive meta-analysis on the difference between omega-3 (fish oils) and omega-6 (vegetable oils) was inconclusive, omega-6 PUFA vegetable oils have been found to be pro-inflammatory. But, because they lower cholesterol levels, they were quickly adopted as healthy alternatives to saturated fats.

More studies need to be done on the intake of specific kinds of omega-6 fatty acids, as not all PUFAs are created equal. (9)

Suggesting that highly processed polyunsaturated omega-6 fatty acids are somehow better than pure coconut oils or saturated fats seems misleading. (7)

Conclusion: “You cannot have your cake and eat it too.”

There is no doubt it would be a bad idea to add more saturated fat to the diet of someone who has liver and gallbladder congestion from years of processed foods.

But, for healthy people who are not consuming a large amount of processed foods and do not fall into the SAD category, a certain amount of saturated fat can be beneficial.

This has been proven time and time again in cultures in which large amounts of saturated fats and coconut oils are consumed. In those coconut-eating cultures, cardiovascular disease rates are consistently lower than in Western-diet cultures. (3)

When these traditional cultures begin eating more processed food and a Westernized diet, the benefits of coconut oil were quickly reversed. (3)

Unfortunately, as the old saying goes, “You cannot have your cake and eat it too.” We get our energy from either saturated fat or starch.

Eating a diet of sugary and highly processed foods with a resultant congested liver and gallbladder, all with some coconut oil spread on top, is a true recipe for disaster.
