There is no shortage of health advice out there, and no shortage of bad advice to go along with it. Some misguided notions are harmless—but others are outright dangerous and can lead you down the road to chronic health problems and may even trim years off your life.
It is critically important to decipher fact from fiction. Many nutrition myths get repeated over and over until they are mistaken for truth, especially when perpetually spread by public health authorities.
But the good news is that slowly, the real truth finally appears to be reaching mainstream audiences, as evidenced by the eagerness of satirists to take a jab at the food industry, as in the clever Coca-Cola parody featured above.
In an article addressing destructive nutrition lies, Kris Gunnars of Authority Nutrition1 is among those admirably trying to bust the dangerous dietary myths that continue being spread by so many nutritionists. I agree with the majority of his points, but have added a few others that I believe to be important. Read on for my own top 10 list, which builds upon his.
Lie #1: Breakfast Is the Healthiest Meal of the Day, and You Should Eat Many Small Meals a Day
How many of you had mothers who would not let you leave the house without breakfast? Mother may have known best about some things—but as it turns out, this wasn’t one of them. There is now a good deal of research supporting the health benefits of intermittent fasting—which is what you were really doing by zipping out of the house without breakfast.
Recent studies suggest that intermittent fasting can provide the same health benefits as constant calorie restriction which many studies have shown to dramatically increase life span in animals. It may also be helpful for those who cannot successfully reduce their everyday calorie intake.
Besides turning you into an efficient fat burner, intermittent fasting can also boost your level of human growth hormone production (aka the “fitness hormone”) by as much as 1,200 percent for women and 2,000 percent for men.
Intermittent fasting and continuous calorie restriction have both been shown to produce weight loss and improve metabolic risk markers. However, intermittent fasting tends to be slightly more effective for reducing insulin resistance.
Other benefits include reducing inflammation, improving blood pressure, and increased lean body mass. Intermittent fasting can also improve your brain function by increasing levels of BDNF, a protein that protects your brain cells from the changes associated with Alzheimer’s and Parkinson’s disease.
There are several types of intermittent fasting to choose from, so I recommend experimenting to see what style works best for you. One of the easiest, however, is to simply skip breakfast, and limit your eating to a narrow window of time each day—say between 11am and 7pm, to start. You can review my more comprehensive article on intermittent fasting for more details.
The advice to “eat six small meals per day” comes from seemingly logical principles (portion control, keeping your energy up, stabilizing blood sugar, etc.), but in reality, eating this way has not been shown to provide these benefits. We seem to need periods of fasting for optimal metabolic function.
And if you think about it, our ancient ancestors never had access to a grocery store 24/7 and they went through regular periods of feast and famine. The problem is that most of us are in 24/7 feast mode. Implementing intermittent fasting is the quickest way I know of to jump start your body into burning fat as its primary fuel again.
Lie #2: Saturated Fat Causes Heart Disease
The dangerous recommendation to avoid saturated fat, which arose from an unproven hypothesisfrom the mid-1950s, has been harming people’s health for about 40 years now. As recently as 2002, the “expert” Food & Nutrition Board issued the following misguided statement, which epitomizes this myth:
“Saturated fats and dietary cholesterol have no known beneficial role in preventing chronic disease and are not required at any level in the diet.”
Similarly, the National Academies’ Institute of Medicine recommends that adults get 45-65 percent of their calories from carbohydrates, 20-35 percent from fat, and 10-35 percent from protein. This is the polar opposite of an ideal fat to carb ratio and virtually guarantees you a heightened risk of disease.
Most people benefit from a diet where 50-85 percent of daily calories are derived from healthful fats. However, you need very few, if any, carbohydrates for optimal health. Although that amount of fat may seem like a lot, fat is very calorie-dense, and will therefore still constitute the smallest amount, in terms of volume, on your plate.
The truth is, saturated fats from animal and vegetable sources provide the building blocks for your cell membranes and a variety of hormones and hormone-like substances, without which your body cannot function optimally.
Fats also serve as carriers for the fat-soluble vitamins A, D, E, and K and are required for converting carotene into vitamin A, absorbing minerals, and a host of other important biological processes. Saturated fat is also the preferred fuel for your heart! Good sources of healthy fats to add to your diet include:
Lie #3: High Omega-6 Seed and Vegetable Oils Are Good for You
Of all the health-destroying foods on the market, those made with highly processed vegetable and seed oils are some of the worst. When consumed in large amounts, as they are by most Americans, they seriously distort your important omega-3 to omega-6 ratio. In a perfect world, this ratio is 1:1—but the average American is getting 20 to 50 times more omega-6 fats than omega-3 fats. Excessive omega-6 fats from processed foods significantly increase your risk for heart disease, cancer, Alzheimer’s, diabetes, rheumatoid arthritis, and many other illnesses.
The cholesterol found in arterial plaque is oxidized, damaged cholesterol, which your immune system identifies as bacteria. In response, your immune system sends out macrophages to attack it, which creates inflammation inside your artery walls. A major factor driving heart disease is this oxidized cholesterol, which you introduce into your body every time you consume vegetable oils, or foods cooked in them.
Many vegetable and seed oils are also genetically engineered, which only compounds their health risk. More than 90 percent of US canola oil is GE. So what’s the best oil to cook with? Of all the available oils, coconut oil is the one of choice for cooking because it’s close to a completely saturated fat—meaning, much less susceptible to heat damage. And coconut oil is one of the most nutritionally beneficial fats. For more information about coconut oil, please see our special report. Olive oil, while certainly a healthful oil, is easily damaged by heat and is best reserved for drizzling cold over salad.
