Heart Specialist Calls for Major Repositioning on Saturated Fat, as it’s NOT the Cause of Heart Disease
By Dr. Mercola
For the past 60 years, conventional medical authorities have warned that saturated animal fats cause heart disease and should be severely restricted in a heart-healthy diet.
As of 2010, recommendations from the US Department of Agriculture1 (USDA) call for reducing your saturated fat intake to a mere 10 percent of your total calories or less. This is astounding, considering the fact that many health experts now believe you likely need anywhere from 50 to 70 percent of healthful fats for optimal health!
It’s virtually impossible to estimate how many people have been prematurely killed by the persistent promulgation of this myth, grown from a flawed study published over half a century ago, that has since been soundly debunked by many decades of research subsequently published.
Most recently, an editorial in the British Medical Journal2 titled: From the Heart, Saturated Fat is Not the Major Issue, has garnered much media attention as it sends a contrary message by saying it’s time to bust the myth that saturated fat consumption causes heart disease.
Saturated Fat Does NOT Promote Heart Disease
The avoidance of saturated fat actually promotes poor health in a number of ways, compounding the health risks of following this completely outdated and dangerous advice. As stated by the author, Aseem Malhotra, an interventional cardiology specialist registrar at Croydon University Hospital in London:
“The mantra that saturated fat must be removed to reduce the risk of cardiovascular disease has dominated dietary advice and guidelines for almost four decades. Yet scientific evidence shows that this advice has, paradoxically, increased our cardiovascular risks....
We've long acknowledged that the Western diet is associated with increased rates of obesity, diabetes, heart disease, hypertension, and cancer. Yet the conventional paradigm is extremely reluctant to accept that it is the sugar contentof this diet that is the primary culprit.
Furthermore, it’s been firmly established that it’s the trans fat found in margarine, vegetable shortening, and partially hydrogenated vegetable oils that is the true villain when it comes to heart disease, as they increase your LDL levels, or "bad" cholesterol, while lowering your levels of HDL, known as "good" cholesterol. Trans fats also contribute to type 2 diabetes and other serious health problems.
Carbohydrates/Sugar, Not Fat, is the Root of Heart Disease
Unfortunately, many doctors and health officials alike are still trying to assure you that you can safely indulge in sweet treats, provided it’s in moderation. This line of reasoning completely falls apart however, if you eat a diet consisting primarily of processed foods, because virtually ALL of them are loaded with processed carbohydrates and fructose.
Cutting out a few desserts or restricting the amount of sugar you add to your coffee or sweet tea, for example, will barely make a dent if you're consuming a lot of processed foods and beverages besides pure filtered water.
I've previously written about how various foods and beverages contain far more sugar than a glazed doughnut. Take Vitamin Water, for example. One 20 oz bottle contains 33 grams of sugar, which equates to THREE Krispy Kreme original glazed doughnuts!
One of the reasons for this overabundance of sugar in processed foods is due to the fact that when you remove the fat, the food tends to lose its taste.
Food companies compensate by adding processed fructose, salt, and other proprietary flavorings. Making matters worse, refined sugars are highly addictive, and cause metabolic dysfunction that leads to overeating and stubborn weight gain.
A high-sugar diet dramatically raises your risk for both type 2 diabetes and heart disease by promoting metabolic syndrome, which includes the following cluster of health conditions:
In short, when you reduce saturated fat and increase refined carbohydrates, you end up promoting obesity, diabetes and heart disease. This is a perfect example of how it can take the conventional medical establishment DECADES to catch up to the truth, and I’m pleased to see that this issue is finally gaining some well-deserved press.
Still, I fear it may be many years before the conventional medical wisdom fully appreciates the value of saturated fats...As for the disease-promoting actions of sugar, two brilliant researchers in this area are Dr. Robert Lustig and Dr. Richard Johnson, both of whom I’ve interviewed and featured on a number of occasions. According to Dr. Lustig:3
"The problem with sugar isn't just weight gain ... A growing body of scientific evidence is showing that fructose can trigger processes that lead to liver toxicity and a host of other chronic diseases. A little is not a problem, but a lot kills -- slowly."
Busting the Calorie Myth
Another related myth is that eating fat causes weight gain, and associated health problems. This too has been firmly debunked (see research below). Eating healthful fat does NOT make you fat. Eating refined carbohydrates/sugar, trans fat and highly processed vegetable oils does. And Dr. Johnson’s work shows that while excess sugar in any form is harmful, fructose is the worst of the bunch. So far, scientific studies have linked fructose to about 78 different diseases and health problems.4
Fructose raises your uric acid levels, typically generating uric acid within minutes of ingestion, which in turn can wreak havoc on your blood pressure, insulin production, and kidney function. Increased uric acid also leads to chronic, low-level inflammation, which has far-reaching consequences for your health. For example, chronically inflamed blood vessels lead to heart attacks and strokes.
Another MAJOR part of why fructose is worse than other sugars is because it is “isocaloric but not isometabolic.” This means you can consume the same amount of calories from fructose or glucose, fructose and protein, or fructose and fat, but themetabolic effect on your body will be entirely different despite the identical calorie count. In the featured editorial,5 Dr. Malhotra addresses this as well, saying:
“The notoriety of fat is based on its higher energy content per gram in comparison with protein and carbohydrate. However, work by the biochemist Richard Feinman and nuclear physicist Eugene Fine on thermodynamics and the metabolic advantage of different diet compositions showed that the body did not metabolize different macronutrients in the same way.
You simply MUST pay attention to the source of the calories. Fat is far more filling than carbohydrates, so replacing refined carbs with healthful fats will automatically reduce hunger. Furthermore, as your body shifts from burning carbs and sugars to burning fat as its primary fuel, your food cravings will significantly diminish. Once you’re fully fat adapted, cravings will be a distant memory. You can use this knowledge to assess your individual fat needs. If you’ve reduced your carb intake and replaced it with healthful fat but still struggle with hunger pangs, it’s a sign that you need to add more fat to your diet.
How Government Dietary Guidelines Promote Obesity and Chronic Disease
It’s important to realize that the government’s nutritional guidelines are in large part mirrored by agricultural subsidies. They’re NOT built upon sound nutritional science. In short, the reason you’re told to make grains the cornerstone of your diet is because that’s what farmers are paid to grow in the US. There’s a lot of it, and it’s inexpensive compared to healthier foods like vegetables, for which few subsidies are offered.
The wacky and nutritionally inappropriate 1992 Food Pyramid had grains as the largest bottom block of the pyramid, encouraging you to eat 6-11 servings of bread, cereal, rice and pasta each day. This excess of carbohydrates, most of them refined, is precisely the kind of diet that promotes fat accumulation and drives insulin resistance and related diseases, including diabetes, heart disease and cancer. At the very top of the pyramid was fats and sugar, and while sugar clearly belongs there, fats do not.
As mentioned earlier, most people would benefit from getting anywhere from 50 to 70 percent of their total calories from healthy fats. Saturated fats from animal and vegetable sources provide a number of important health benefits, and your body requiresthem for the proper function of your:
The food pyramid was replaced with “MyPlate” in 2011, which slightly downplayed grains as the most important dietary ingredient, making vegetables the largest “slice.” One of its most glaring problems with MyPlate is that it virtually removed all fatsfrom the equation! In fact, except for a small portion of dairy, which is advised to be fat-free or low-fat, fats are missing entirely.
There is no mention of the importance of dietary fats, even the "politically correct" ones like the monounsaturated fats in olive oil and nuts, such as pecans (canola oil is also in this category, but I advise avoiding it and using coconut oil instead). Even one of the most critical of all fats is absent from the plate, namely animal-based omega-3 fats. Deficiency in this essential fat can cause or contribute to very serious health problems, both mental and physical, and may be a significant underlying factor of up to 96,000 premature deaths each year... For more information about omega-3s and the best sources of this fat, please review this previous article. In an effort to remedy this atrocious situation, I’ve created my own Food Pyramid for Optimal Health, which you can print out and share with your friends and family.
Studies Showing Saturated Fat is Not Associated with Increased Heart Disease Risk
As mentioned earlier, mounting scientific evidence supports saturated fat as a necessary part of a heart healthy diet, and firmly debunks the myth that saturated fat promotes heart disease. For example:
When you replace saturated fat with a higher carbohydrate intake, particularly refined carbohydrate, you exacerbate insulin resistance and obesity, increase triglycerides and small LDL particles, and reduce beneficial HDL cholesterol. The authors state that dietary efforts to improve your cardiovascular disease risk should primarily emphasize the limitation of refined carbohydrate intake, and weight reduction.
How to Regain Your Health and Avoid Heart Disease
Remember, insulin- and leptin resistance are at the root of most chronic diseases, including heart disease. To safely and effectively reverse insulin and leptin resistance, you need to:
Remember, one of the most important fats your body needs for optimal health is animal-based omega-3. Deficiency in this essential fat can cause or contribute to very serious health problems, both mental and physical, and may be a significant underlying factor of up to 96,000 premature deaths each year. For more information about omega-3's and the best sources of this fat, please review this previous article. Besides animal-based omega-3 fats, other sources of healthy fats to add to your diet include:
Healthy Fat Tips to Live By
As reported by Medical News Today:9
“Dr. Malhotra urges doctors to "embrace prevention as well as treatment." Drugs can alleviate symptoms but they can't change the "pathophysiology," he says, and concludes: "It is time to bust the myth of the role of saturated fat in heart disease and wind back the harms of dietary advice that has contributed to obesity."
The most effective prevention strategy you’ll likely ever find is your diet—the foods you do and do not eat every day. Dr. Malhotra recommends a Mediterranean-style diet, which has been shown to be three times more effective than statin drugs at reducing cardiovascular mortality.
A Mediterranean-style diet is basically a whole-food diet. And that is indeed key for any healthy diet. As Dr. Sanjay Gupta accurately points out in the featured video, the answer is to EAT REAL FOOD. This change alone will dramatically reduce the amount of refined sugar and processed fructose in your diet. It will also address the issue of healthful versus harmful fats in your diet. Believe me, you’d be hard-pressed to find a processed food containing healthful fat... Besides eliminating processed foods, the following tips can help ensure you’re eating the right fats for your health:
