Dr. Mark Hyman: So Is Coconut Oil Healthy or Not?

Did you know that 50 percent of media headlines about medical studies are dead wrong? And that many of these headlines don't accurately match the conclusions of the studies they cover? That's from a review published in the New England Journal of Medicine.

It makes me sad and furious at the same time that journalists don't do their homework and create firestorms of confusion because of their negligent work.


That is exactly what happened when USA Today published their article, Coconut Oil Isn't Healthy. It's Never Been Healthy. Shame on you USA Today editors for doing such a sloppy job of journalism.

Why the American Heart Association Has Been and Still Is Wrong

First, there is not a single study showing that coconut oil causes heart disease. Not one. Second, the whole case against coconut oil is founded on a hypothesis that has been proven wrong. It's the diet-heart hypothesis. Saturated fat raises LDL cholesterol. LDL cholesterol causes heart disease. Anything that raises LDL cholesterol is bad. Only problem is that the data does not support this hypothesis.

If you are geeky and want to read more where I cover the science in detail, read my blog Fat: What I Got Wrong, What I Got Right. But just like it took 150 years after Copernicus recognized that the earth revolves around the sun before it was finally accepted, it will take a while for the world to catch up with the false idea that low-fat and low-cholesterol diets won't save us from heart disease. In fact, low-fat diets cause heart disease. I have covered all this in my last book, Eat Fat, Get Thin with hundreds of references.

The USA Today article was based on a review by the American Heart Association (AHA). They published a review of fat and heart disease. The AHA has been at the vanguard of bad advice for decades since they first hooked onto the "fat is bad and will kill you" meme. They told us to eat very low fat, low cholesterol diets and to eat tons of starchy carbs. By the way, the AHA gets huge funding from cereal makers that put the AHA seal of approval on sugary (including cereal makers) cereals because they are "fat free" despite containing 75 percent sugar. Except now the overwhelming amount of research has proved that idea to be dead wrong. In fact, their recommendations have killed millions of people (no joke) from heart disease and diabetes. That's why the very conservative 2015 USDA Dietary Guidelines removed any upper limits on dietary fat and eliminated any restrictions on dietary cholesterol. In fact, after decades of telling us to avoid eggs and shrimp they said, "Cholesterol is not a nutrient of concern for overconsumption."

If you are interested in the corruption of the AHA, its funding is supported by the Pharma industry, industrial food giants (including sugary cereal makers) and industrial vegetable oil manufacturers, then read this recent blog on Medium entitled, Is the American Heart Association a terrorist organization? I'm not calling the AHA a terrorist organization, I just want you to read the article and question who's really pulling the strings.

How could this happen you might wonder? How could the scientists have gotten it so wrong? It all comes down to how we do the research. Most nutrition research is based on what we call observational studies. You follow a group of people for a long time, you ask them once a year what they ate last week and you see if patterns emerged. Good luck if they can remember. And people aren't always honest—if they think butter is bad, then they will underreport consumption. Problem is those types of studies do not prove cause and effect, just correlation. If I did a study on women over 55-years of age who have sex, I could conclude that sex rarely leads to pregnancy. Pretty meaningless. The populations studied that ate saturated fats also were coincidentally smokers, didn't exercise and ate otherwise unhealthy diets. Those who actually ate well, exercised and didn't smoke (i.e. lead healthier lifestyles) also didn't eat saturated fats because they were told not to. Studies prove that it was the well-rounded healthy habits that saved them, not less saturated fats.

Why Saturated Fats Are Not Bad and Are Essential for Health

This is exactly why multiple recent studies have shown no link between saturated fat and heart disease. You can read most of the important ones from the references, below, in my book and in the Fat: What I Got Wrong, What I Got Right article. In fact, there have been very few cause and effect studies in nutrition—they are hard to do, take a long time and cost a lot. But two of the largest ones every published show that fat and saturated fat are not the problem. The first was the PREDIMED study where researchers gave 7,000 participants olive oil (which contains 20 percent saturated fat) or nuts vs. a low-fat diet. PERDIMED had to stop the study because the people who were following the low-fat diet were dying.

The next study was completed more than 40 years ago, but it wasn't published because the results contradicted the prevailing dogma that saturated fat was bad and that LDL cholesterol caused heart disease. This was a study that could not be conducted today because it would be considered unethical. They fed 9,000 people in mental hospitals butter and saturated fats or corn oil (polyunsaturated vegetable oil, which the AHA report says we should eat more of). And, guess what? Those who ate the corn oil had more heart attacks and deaths, despite lowering their LDL cholesterol. Really? Yes, it's true. In fact, for every 30-point drop in LDL the risk of heart attack went up 22 percent. To top it off a recent review of all the science on big bad butter looking at 6.5 million patient years of butter eating, researchers found that butter eaters had no increased risk of heart disease, but they did have decreased risk of type 2 diabetes. You read that right. Butter = lower risk of type 2 diabetes. And if you still need to be convinced, here's a review of 17 meta-analyses (reviews of all the best and relevant research) showing no link between saturated fat and heart disease.

The whole idea that LDL cholesterol causes heart disease is the reason we have a multi-billion dollar statin industry. One study of more than 130,000 people who had heart attacks over 5 years showed that 75 percent had normal LDL and 50 percent had optimal LDL cholesterol. But only 10 percent had normal HDL or the protective cholesterol. Guess what raises HDL? Saturated fat. And coconut oil raises it the most of any saturated fat. And what lowers it? A low-fat, high-starch and high-sugar diet. We need cholesterol and saturated fat for the health of every cell membrane, for your brain cells, your sex hormones and more. Cholesterol is not the cause of heart disease, it is the band-aid that tries to repair the arteries when damage occurs from a low-fat, high-starch, high sugar diet. This causes pre-diabetes and inflammation from a processed food diet, environmental toxins, a bad gut from a low fiber, processed diet or anything that causes inflammation.

Before we get off saturated fats, here's one big warning. They are a problem if you eat them in the context of a high-sugar, high-starch, processed foods diet. It's what I call sweet fat. Stay away. No bagels and butter. No donuts or French fries. Stick with butter and broccoli.

Why We Shouldn't Be Mainlining Omega-6 Vegetable Oils

The other recommendation from the AHA other than dramatically lower saturated fat intake is to increase omega-6 refined vegetable oils. Bad idea. Yes, some studies show a lower risk of heart disease with a higher intake of omega-6 oils (otherwise known as polyunsaturated fats or PUFAs which include soy, corn, safflower, canola oils). Again I cover this in detail in Eat Fat, Get Thin, but the take-home is this: If you eat saturated fat in the context of the typical American diet, it will cause problems and the people in omega-6 studies were eating exactly that. And to make it more confusing, the studies looking at PUFAs included both omega-3 (super protective) and omega-6 fats. The omega-3s made the omega-6 cousins look better. When you look at just the studies of the effects of omega-6 fats, you find actually increase the risk of heart attacks. And it is just common sense and evolutionary sense—our intake of these refined, heat processed, hexane treated, chemically deodorized oils (never consumed before in human history) have increase more than 1,000 times (that's 100,000 percent) in the last 100 years. Saturated fats make your cholesterol molecules stable and less likely to oxidize or go rancid. It is oxidized cholesterol that causes heart attacks. The PUFA's are unstable and easily oxidized so when they are incorporated into cholesterol they make it unstable and go rancid—which is bad for your heart.

Is Coconut Oil Healthy?

We have had a coconut craze. What's the deal? Broccoli is healthy but if that's all you ate you would get sick. Coconut oil is healthy but only as part of an overall healthy diet, not as the main course. Coconut oil has been consumed by populations in the South Pacific for thousands of years without ill effect. It has so many health benefits. You can read more in my article Is Coconut Oil Bad for My Cholesterol. But here's the short list of benefits. It raises HDL, the good cholesterol. It improves the quality and size and type of cholesterol. It lowers the total cholesterol to HDL ratio—a far better predictor of heart disease than LDL. And cultures with 60 percent of their diet as coconut oil have no heart disease. It also contains a unique type of saturated fat called MCT oil that boosts metabolism, reverses insulin resistance, and improves cognitive function. Coconut oil is also anti-fungal and anti-microbial and it contains lauric acid that is great for immune function. The only other good source of lauric acid is breast milk, which contains 24 percent saturated fat—far higher than the 6 percent the AHA recommends.

Who would you trust, nature/God or the American Heart Association? So, I am sorry you have to be buffeted about by bad conclusions from insufficient outdated science and bad journalism. But hopefully reading this helps, and if you are so inclined check out the references below, my other blogs on this topic and my book so you can come to your own conclusions.

Greenland Melting 4x Faster Than in 2013, and From an Unexpected Source

Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.

"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"

Judge Halts Seismic Testing Permits During Shutdown

Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.

The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.

DiCaprio-Funded Study: Staying Below 1.5ºC is Totally Possible

Climate change has been called the biggest challenge of our time. Last year, scientists with the United Nations said we basically have 12 years to limit global warming to 1.5ºC to avoid planetary catastrophe.

Amid a backdrop of rising global carbon emissions, there's a real case for pessimism. However, many scientists are hopeful of a way out.

Climate Change Leading to Fatal Bird Conflicts

By Marlene Cimons

Most Europeans know the great tit as an adorable, likeable yellow-and-black songbird that shows up to their feeders in the winter. But there may be one thing they don't know. That cute, fluffy bird can be a relentless killer.

The great tit's aggression can emerge in gruesome ways when it feels threatened by the pied flycatcher, a bird that spends most of the year in Africa, but migrates to Europe in the spring to breed. When flycatchers arrive at their European breeding grounds, they head for great tit territory, knowing that great tits—being year-round European residents—know the best nesting sites.

Saving the World’s Largest Tropical Wetland

Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.

Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.
