STORY AT-A-GLANCE
- John Warner, cardiologist and president of the American Heart Association (AHA), recently suffered a heart attack in the middle of a health conference at the age of 52
- In all likelihood, Warner followed AHA recommendations, many of which can actually worsen or cause heart disease
- AHA supports ample grain consumption and recommends eating harmful fats such as canola, corn, soybean and sunflower oil, both of which are known to cause and/or contribute to cardiovascular problems
- Good heart health starts with your diet — what you eat and when you eat. A powerful treatment for heart disease is to work your way up to an intermittent fasting schedule where you’re fasting for 20 hours a day
- When you do eat, make sure you eat real food, and consider a cyclical ketogenic diet, high in healthy fats, low in net carbs with moderate protein. Once you’re comfortable with this intermittent fasting schedule, start doing a monthly water only fast, working your way up to multiple days
In the health paradox of the year, 52-year-old cardiologist John Warner, president of the American Heart Association (AHA), recently suffered a heart attack in the middle of a health conference.1,2 In a statement, the association reported Warner was in stable condition after having a stent placed to open a blocked artery. Part of Warner’s speech at the Scientific Sessions conference in Anaheim, California, centered around his own family’s struggle with heart disease.
“After my son was born and we were introducing him to his extended family, I realized something very disturbing: There were no old men on either side of my family. None. All the branches of our family tree cut short by cardiovascular disease,” Warner said in his speech.3
“Together we can make sure old men and old women are regulars at family reunions, that people live long enough and healthy enough to enjoy walks and fishing trips with their grandchildren and maybe even their great-grandchildren. In other words, I look forward to a future where … children grow up surrounded by so many healthy, beloved, elderly relatives that they couldn’t imagine life any other way.”
The AHA’s CEO, Nancy Brown, said in a statement:4 “John wanted to reinforce that this incident underscores the important message that he left us with in his presidential address … that much progress has been made, but much remains to be done.”
Many AHA Recommendations Worsen Heart Health
In all likelihood, Warner followed AHA recommendations, many of which are actually recipes for heart disease disaster. Of the foods scientifically proven to cause heart disease and clogged arteries, excess sugar and industrially processed omega-6 vegetable oils, found in nearly all processed foods, compete for space at the top the list. And what kinds of foods does the AHA recommend to protect your heart?
Not only does it support ample grain consumption, it also recommends eating harmful fats such as canola, corn, soybean and sunflower oil.5 “Blends or combinations of these oils, often sold under the name ‘vegetable oil,’ and cooking sprays made from these oils are also good choices,” the AHA says. Meanwhile, the association still insists saturated fats are to be avoided.
Just this past summer the AHA shocked health experts around the world by sending out a worldwide advisory6 saying saturated fats such as butter and coconut oil should be avoided to cut your risk of heart disease, and that replacing these fats with margarine and vegetable oil might cut your heart disease risk by as much as 30 percent. Overall, the AHA recommends limiting your daily saturated fat intake to 6 percent of daily calories or less.7
This is as backward as it gets, and if Warner was following this long-outdated advice, it’s no wonder he suffered a heart attack. In fact, it is to be expected. As noted by American science writer Gary Taubes in his extensive rebuttal to the AHA’s advisory,8 with this document, the AHA reveals its longstanding prejudice — and the method by which it reaches its flawed conclusions.
In short, the AHA simply excluded any and all contrary evidence. After this methodical cherry-picking, they were left with just four clinical trials published in the 1960s and early ‘70s — the eras when the low-fat myth was born and grew to take hold. The problem is nutritional science has made significant strides since then, and a number of significant studies have firmly disproven the hypothesis that saturated fat causes heart disease, finding no association whatsoever.
In related news, the AHA recently issued new guidelines on blood pressure,9 moving the goal post for heart health yet again. Now you’re considered hypertensive if your blood pressure is above 130 over 80. Previous guidelines started hypertension at 140 over 90. This means an estimated 30 million Americans will qualify for the designation of having high blood pressure, and of those, an estimated 1 in 5 are likely to receive the recommendation to take blood pressure medication.
Flawed Fat Recommendations Have Been Followed With Disastrous Consequences
Since the 1950s, when vegetable oils began being promoted over saturated fats like butter, Americans have dutifully followed this advice, dramatically increasing consumption of vegetable oil. Soybean oil, for example, has risen by 600 percent while butter, tallow and lard consumption has been halved. We’ve also dramatically increased sugar consumption, which has also been implicated as a primary contributor to heart disease and other chronic health problems.10
While following this advice, Americans have gotten fatter and sicker. Heart disease rates have not improved even though people have been following the AHA’s “heart healthy diet.” Common sense tells us if the AHA’s advice hasn’t worked in the last 65 years, it’s not likely to start working now. Modern research is just now starting to reveal what actually happens at the molecular level when you consume vegetable oil and margarine, and it’s not good.
For example, Dr. Sanjoy Ghosh,11 a biologist at the University of British Columbia, has shown your mitochondria cannot easily use polyunsaturated fatty acids (PUFAs) for fuel due to the fats’ unique molecular structure. Other researchers have shown the PUFA linoleic acid hinders mitochondrial function and can even cause cell death.12
PUFAs are also not readily stored in subcutaneous fat. Instead, PUFAs tend to get deposited in your liver, where they contribute to fatty liver disease, and in your arteries, where they contribute to atherosclerosis.
According to Frances Sladek,13 Ph.D., a toxicologist and professor of cell biology at UC Riverside, PUFAs behave like a toxin that builds up in tissues because your body cannot easily rid itself of it. Making matters worse, when vegetable oils like sunflower oil and corn oil are heated, cancer-causing chemicals like cyclic aldehydes are also produced.14
Vegetable Oils Are Anything but Healthy
Other research confirms such findings by linking fried foods to an increased risk of death. For example, eating fried potatoes more than twice a week has been shown to double a person’s risk of death compared to never eating fried potatoes.15 Animal and human research has also found vegetable oils promote:
- Obesity and fatty liver16
- Lethargy and prediabetic symptoms17
- Chronic pain/idiopathic pain syndromes (meaning pain with no discernible cause)18
- Migraines19
- Crohn’s disease and ulcerative colitis20
According to Dr. Cate Shanahan,21 a family physician and author of “Deep Nutrition: Why Your Genes Need Traditional Food,” the idea that PUFAs are healthier than saturated fats falls flat when you enter the field of biochemistry, because it’s “biochemically implausible.” In other words, the molecular structure of PUFA is such that it’s far more prone to react with oxygen, and these reactions disrupt cellular activity and cause inflammation.22 Oxidative stress and inflammation, in turn, are hallmarks not only of heart disease and heart attacks but of most chronic diseases.23,24
[T]he folks at the AHA claim saturated fat is pro-inflammatory and causes arterial plaque and heart attacks — but there is no biochemically plausible explanation for their argument,” she told me in an emailed rebuttal to the AHA advisory. “Saturated fat is very stable, and will not react with oxygen the way PUFA fat does, not until the fundamental laws of the universe are altered. _
Our bodies do need some PUFA fat, but we need it to come from food like walnuts and salmon or gently processed (as in cold pressed, unrefined) oils like flax and artisanal grapeseed, not from vegetable oils because these are refined, bleached and deodorized, and the PUFA fats are molecularly mangled into toxins our body cannot use.”_
