It is an interesting story. I write extensively about the history behind the “Low Fat Myth” in Chapter Two (“Fix Your Fats”) of my book The Perfect Metabolism Plan. I also I highly recommend this fascinating must-watch documentary featuring a number of doctors and experts that discusses these “dietary villains” – The Heart of the Matter – this is part 1 (approx. 30 mins long).
The long-standing recommendation to limit the amount of dietary cholesterol has just recently been officially lifted from the nutritional guidelines. This is huge, and has been a long time coming. Despite being told that there was good scientific evidence to back it up – the scientific studies actually did not show a causative link between dietary cholesterol and heart attack! One study looked at 130,000 people and found that nearly 3/4 of patients hospitalized for heart attack had what was considered to be normal cholesterol numbers. In fact, research shows that in the elderly population (over age 81) – lower cholesterol levels actually raised the risk of mortality, and equated to lower memory scores.
Dr. Mark Houston, author of What Your Doctor May Not Tell you About Heart Disease says that “elevated cholesterol is not a sure sign of heart disease, any more than low levels are a sure sign of heart health.” Dr. Houston says in his book that heart disease begins with endothelial damage or dysfunction, which progresses through 7 different pathways (inflammation, oxidative stress, autoimmunity, dyslipidemia, high blood sugar, high blood pressure, and obesity). The good news? Many of the above pathways can be affected by nutritional and lifestyle factors. I highly recommend Dr. Houston’s book if you want to understand how to get control of your heart health naturally.
Experts are also calling into the question the recommendations on saturated fats – because like cholesterol, there is a lack of scientific evidence linking saturated fats to heart disease. But the push to remove the saturated fat limit is still being met with a lot of resistance, so it will likely not be changed in the official nutritional recommendations until the next time they are changed – which is in 5 years. Don’t believe me about saturated fats not being bad for you? Read this Time Magazine piece titled “We Were Wrong About Saturated Fats.” (Notice that is Ancel Keys on the left hand cover).
Another exciting development that happened recently – is the FDA finally took a stronger stand against trans fats. Back in 2013, they removed the GRAS (generally recognized as safe) classification, because of the link between trans fats and coronary artery plaque formation. And just last month they took it a big step further – they banned the use of trans fats in foods entirely. This is great news, but since there is a 3 year grace period for compliance – we all need to be aware of all the places trans fats are hiding in the meantime. Basically – the majority of trans fats in our diets come from “convenience foods.”
Trans fats are liquid fats that have been altered by partially hydrogenation, making them solid/more stable at room temperature. Trans fats extend the shelf-life of a product, so that is why manufacturers love them. An interesting historical note is that Crisco – which is partially hydrogenated vegetable oil – was brought to market in 1911. Check out this Illustrated History of heart disease for other interesting facts and historical notes (from 1825-2015).
Just because a label says “no trans fats” does not mean it doesn’t contain them. That is a label loophole, and just means that there is less than half a gram of trans fats per serving. Just know, if it says “partially hydrogenated oil” on the ingredient list – it has trans fats.
There is a lot of really exciting research that has been happening about the human microbiome (the bacterial cells in and on our bodies). With some new research linking the heart to the microbiome in the gut. Check out these articles to learn more about the connection:
There is emerging research to support a link between autoimmune diseases and heart disease. It is well-known that there is a link between chronic/systemic inflammation and heart disease. So it makes sense that having an autoimmune disease, which leads to chronic and systemic inflammation – could be one potential underlying cause/contributing factor for heart disease. Because of this, it is a good idea for anyone with heart disease to be tested for celiac disease/gluten sensitivity (especially if there are other potential symptoms of autoimmunity – such as psoriosis, eczema, or other skin conditions/rashes, sun sensitivity, thyroid disease, chronic aches & pains/arthritis, stress fractures, slow wound healing, low white blood cell count, etc).
There is a lot of overwhelming evidence pointing to poorly controlled blood SUGAR.
Although not likely the whole picture – excess sugar increases inflammation, and is linked to increased risk of heart attack and death. Chapter One of my book The Perfect Metabolism Plan goes into detail about how sugar impacts our metabolism and health – and all the sneaky ways it is getting into our diet.
AHA Recommends Added Sugar Limits
Because of the link between sugar and heart disease, the American Heart Association recommends limiting sugar intake to less than 9 tsp for men, and 6 tsp for women. But with 75% of all packaged foods containing added sugars – this is not easy to do. Sugar is sneaking into our diets all day long – even in seemingly healthy choices like cereals, yogurts, salad dressings, sauces, snack bars, etc. You do not have to eat one cookie, one spoonful of ice cream, or one soda to get more added sugar than the recommended limit. It is no wonder that the average American gets about 3 times more than the recommended amount every day (and I personally think that number is underestimated).
Skip the Sodas & Sweet Drinks
One of the fastest way to get too much sugar is by drinking it. One 12 oz. soda has about 10 tsp of sugar, and a 9 oz. frappuccino has about 8 tsp. One medium FruiTea (organic green tea from Wendy’s) has 18 tsp!! That drink alone is 3 times the amount a woman should have all day long!! And before you run out to buy diet sodas – know that two or more diet sodas a day has been linked to a 30% increase for a heart attack (read this article to learn more).

One way to stay on top of our heart health is to get some tests run. But which ones? Contrary to popular belief – just knowing your cholesterol levels is not enough – as more than half of all heart attacks happen in people who have what are considered normal cholesterol levels.
The Spectra Cell Cardio Metabolic test is a comprehensive test to help you assess your risk of metabolic syndrome. Learn more about the test here – or ask your family doctor or cardiologist to run these tests for you.
