Is eating egg yolks as bad as smoking?

A new study suggests eating egg yolks can accelerate heart disease almost as much as smoking.

The study published online in the journal Atherosclerosis found eating egg yolks regularly increases plaque buildup about two-thirds as much as smoking does. Specifically, patients who ate three or more yolks a week showed significantly more plaque than those who ate two or less yolks per week.

It may seem harsh to compare smoking with eating egg yolks, but lead study author Dr. David Spence says researchers needed a way to put it into perspective since both eating cholesterol and smoking increase cardiovascular risks - but the general public believes smoking is far worse for your health.

The issue is with the yolk, not the egg, says Spence, who is also a professor of neurology at the University of Western Ontario's Schulich School of Medicine & Dentistry. "One jumbo chicken egg yolk has about 237 milligrams of cholesterol."

Keeping a diet low in cholesterol is key, says Spence.  Even if you are young and healthy, eating egg yolks can increase the risk of cardiovascular diseases later.

"Just because you are 20 doesn't mean egg yolks aren't going to cause any trouble down the line," he says.

Study: Egg yolk nearly as bad as smoking

For those patients with increased coronary risk, such as diabetics, eating an egg yolk a day can increase coronary risk by two to five-fold, he adds.

Atherosclerosis, also called coronary artery disease, occurs when plaque builds up in the blood vessels leading to the heart, specifically the inner arterial wall, and limits the amount of blood that can pass through.

Doctors write a prescription for fresh produce

In the study, researchers looked at 1,231 patients of the vascular prevention clinics at London Health Sciences Centre's University Hospital, with a mean age of 61.5. Each patient had already experienced a small stroke or  had high blood pressure, hypertension or a family history of cardiovascular disease. Spence says researchers chose to use patients with a higher likelihood of cardiovascular issues because it would have been harder to get visible results using the general population with a lower risk.

Patients were asked to fill out questionnaires about their diet, lifestyle and medications, including how much they smoked and the number of egg yolks they ate.  An ultrasound was performed to examine their plaque buildup. Researchers took into account sex, cholesterol, blood pressure, smoking, body mass index and diabetes.

In addition to relying completely on the recollection of patients as to what they ate, the study did not account for waist circumference and it did not account for a patient's exercise program.  And perhaps most notably, it only looked at patients with existing cardiovascular issues.

The study confirms what doctors already know about eating cholesterol and cardiovascular disease, says Dr, Gordon Tomaselli, chief of cardiology at John Hopkins University School of Medicine and the former president of the American Heart Association.

"Cholesterol intake should be limited to 300 milligrams a day, particularly in people who do not have underlying heart disease," he says.

However, people with high LDL blood cholesterol levels or those taking a blood cholesterol-lowering medication should eat less than 200 mg of cholesterol per day.

So what can you do to keep your heart healthy?

Talk to your doctor if you have a history of heart disease and consider a change in lifestyle – things like eating better, watching your cholesterol, stopping smoking, and exercising.

    If the person takes enough time out of their today to seperate EGG WHITES., Chances are that person doesn't eat FAST FOOD REGULARLY HAS TIME TO EXCERCISE. How about doing this research. Do people who remove egg whites for NUTRITIONAL REASONS AND NOT HEALTH REASON have more time to EXCERCISE?

      It takes all of 10 seconds to separate an egg. This idea that we have no time to do trivial tasks is a crutch used by lazy people (and I include myself in that group).

      The article says that they asked questions about the subjects' diet (including, but not limited to whether they ate egg yolks). This study does have limited generalizability, but I suspect that they correctly controlled for the other foods people ate. They also asked about "lifestyle", which I would also expect to include daily exercise. I take greater issue with the sensationalist headline, rather than this study, which does point out a significant finding regarding a single inportant outcome: coronary disease.

      There is zero excuse for not having time to exercise, even if for five minutes. You can do it while watching tv. It takes zero effort. Amazing how everyone has time to check facebook every hour, but god forbid they lift dumbells while watching American Idol, or while blabbing/texting about NOTHING on their phones. People are busy...being inefficient and then whining about it after they're done trying to appear more busy than they are.

      Does this include pasture-raised eggs? Eggs raised in feedlots / CAFO situation are much higher in cholesterol and lower in vitamins and minerals than their pasture-raised counterparts. "You are what they eat." I'd rather eat an egg out of the pasture in my backyard than conventionally grown GMO soy beans.

      I have had two eggs and toast for breakfast almost every day of my adult life. I am now 64. I recently had my carotid arteries scanned and they were totally clear. Serum cholesterol is primarily manufactured by the liver. The American Heart Association diet can only reduce serum cholesterol by about 10%, or 20 points. To say that eating eggs is equivalent to smoking discredits the study, in my opinion. Eggs yolks contain some vital nutrients, including methionine and vitamin A. Methionine helps with brain function. Try eating pancakes for breakfast and see how alert you are.

      Give me a break. Bodybuilders are no worse off eating 12 egg yolks a day than those who eat fast food 3 or 4 times a week. This study does not take into account how much meat they ate, how much fatty food they ate, etc. Or at least they forget to mention that small tidbit in this lame article. Plus this study is pretty unreliable since there were no controls on what else these people were eating and it relies on the participants memory on what they eat. So someone posts a story on this study and now no one should eat egg yolks? How about actually doing a real controlled study then publish the results. My grandfather raised chickens and ate eggs everyday of his life. He is 84 and has no signs of heart disease. Trust me he would never seperate the yolk from the white.

    It's great to see so many people with their feet on the ground in the face of such a lopsided "study"! I have a typical allergic reaction to most commercially produced eggs, but it's not the eggs. It's what they are feeding the chickens. When I stick to organic there is absolutely no allergic reaction whatsoever and I'm talking a couple of boiled eggs a day. (my cholesterol, BP, etc are fine, by the way). We wouldn't know unless a formal study with responsible reporting were done, but I firmly believe that the chemicals we are now unable to avoid in the food supply are at the bottom of many of the health problems we now face. Some cases of obesity, autoimmune disorders, digestive problems, can all be traced to these agricultural, processing and packaging chemicals. Just because something doesn't give you cancer within 6 months or cause a visit to the ER doesn't make it safe, it might just be underlying your misery.

    The weaknesses of this study include the fact that it is retrospective and based on survey data, which is notoriously inaccurate. Further, it is an observational study and therefore there are many confounding factors that are not controlled for. Perhaps people who eat more egg yolks also eat more bacon, or have a generally poorer diet, or don’t exercise as much.

    Apparently what the authors have shown (which is consistent with previous data) is that eating lots of eggs does not increase total cholesterol or bad cholesterol (LDL) nor does it decrease good cholesterol (HDL). In my mind this leaves the authors completely without a mechanism to explain a causal relationship between egg consumption and carotid plaque. This strongly suggests the association is not causal but is incidental or spurious – unless an alternate mechanism can be proposed and supported by evidence.

    A HAP sponsored nutritionist told me recently that the cholesterol in egg yolks is not absorbed unless it is eaten with a saturated fat, i.e. it isn't the eggs but the bacon'n'eggs.

      Everything is "genetically modified" if it has DNA. You, me, the lettuce in my fridge, and everything else you eat short of Twinkies. Vegetables were selectively bred over hundreds of years. Even your "heirloom" veggies. Chickens were selectively bred from Indian jungle fowl. Any time something is bred for certain qualities, it is being genetically modified. It's just evolution. Doing it in a lab only speeds the process up. Not to mention GMO crops have already saved millions from starving across the globe. Unless you do your grocery shopping in a time machine and eat the earliest of amoebas, you're eating genetically modified food.

    The fact that they used subjects already showing some signs kind of makes the experiment flawed. I understand they want to see results faster, but there could already be a common factor causing it unrelated to eggs in the subjects they chose. I can't believe they didn't account for exercise though.

    I eat several eggs or more a day. And have done that for years. My cholesterol actually comes up low (both LDL and HDL). I wonder what sort of curve that throws into their study?

    Actually I think the study seems very flawed. You're making the assumption that these are typical results. The article states that they only choose people at high risk because they didn't feel they would be hard to show any visible results. It would seem that they already had a bias as to a desired outcome and were skewing the test to produce the data to tailor fit the anticipated data.

    You could just as easily take a group of the same people and pick some common trait and attribute that to causing higher cholesterol levels. Maybe a better article would be that higher cholesterol intake among people with higher risks of elevated cholesterol levels leads to increased plaque build up, but no real correlation has been found in people who are not at higher risk. That I might buy into.

    Just the other day I read another 'in depth scientific' study that found no correlation between eating several eggs per day and elevated cholesterol. It was more due to insulin resistance and the amount of free glucose in the blood stream, stored in the liver and muscle cells.

    Maybe the two groups need to get together and hash that out before articles appear implying that smoking is healthier than eggs. Rubbish.

    Would whoever extrapolated the results of the study to the general population explain why they think no bias was introduced in the process? Do they claim that the observed sample is in fact representative of the general population? Or did CNN introduce that spin?

It also surveyed people with a history of heart disease and didn't take into account important variables such as diet, exercise, and general lifestyle habits.

    I have a lot of issues with this article. First and foremost is controlling for eggs consumed from free range chickens and those from conventionally raised chickens who live in cages pretty much their entire lives. Almost a completely different food and the study should have accounted for that. Also the median age for the control group was 61.5 and so a lot of their findings are based on participants stating how many eggs they've consumed on average for the last 20 years or so. I don't know about you, but I don't eat eggs by themselves and usually have them with some wheat toast, pancakes, sausage or bacon. That's just me. But I'm sure the researchers thought of that. So to isolate egg yolk as the culprit for increased arterial plaque seems presumptive. Eat real food in moderation and you'll be fine....and I don't need a study to tell me that.

    Its a shame that the medical community can continue to push anti-cholesterol and anti-saturated fat garbage that has no basis in fact. You want to know how people started to think that cholesterol was bad? They gave it to rabbits and they died. A rabbit is an herbivore! Of course rabbits were not meant to ingest cholesterol.

    Pastured raised eggs are one of the most nutritious foods with plenty of omega 3s and other vitamins and minerals contained in the yolk. I'm sure eating your every day supermarket egg would likely not be that good for you, but it is not like the medical community actually cares about teaching people to be healthy.

    This article is ridiculous. They find a linear relationship and try to forge some bogus causation relationship that has no basis in fact and is simply misleading.

    Even ignoring all the issues with a retrospective study, which others have already pointed out, the premise of this article is still bull.

    Even if they are right (and I'm not saying they are) and eggs are as bad for your cardiovascular heath as smoking, eggs still wouldn't be nearly as bad for you as smoking.

    What's the first negative health consequence you think of for smoking? Lung cancer. Next? Emphysema. Next? Throat cancer, various other cancers, a ton of respiratory issue... It's a long list and most of it does not fall under the banner of cardiovascular health.

    Until and unless they link eggs to the rest of all that too, no way you can compare eggs to smoking.

    if this was legit, i would certainly take it to hear and adjust accordingly. but this is weak. provide the data, or at worst the results from the abstract. diffrenence in plaque area was marginal between those who consumed eggs versus those who didn't. not to mention that the margin of error was greater than the measurement in TPA itself, so as to render the results almost meaningless.

    furthermore, about a little info about the other pieces of their diet........ this is probably someone doing a study on heart disease and smoking and came to some other conclusion from the data. 100% of those polled in here are smokers. we won't know, though, because CNN chose to not do any actual reporting here. why do you insist on chasing headlines without looking at research? this does the entire population a diservice

    A few years ago, there was another stidy that came out saying that eggs were founf to have 1/4 of the cholesterol than we originally thought. they keep going back and forth. You just can't trust these studies. The results vary depending on who is conducting (or paying for) the study. They are usually just trying to promote their own product or service. So these studies often yield results that are favorable to the organization conducting or financing the study.

    All foods are good to eat. Smoking is not so bad either. The problem that we have created for ourselves is simply all the additives that we put into our foods (or into the animals that give us our food) to keep color, freshness, shape or whatever. Those chemicals are what is killing us by causing cancer and countless other maladies. Smoking (and second hand smoke, which has never been definitively proven to cause cancer) is singled out as the big bad monster for a simple reason. Just imagine what will happen to society if it were revealed that the foods we eat (and pretty well any product we use) cause cancers at such an alarming rate.

    This "new study" is a load of hooey. I'm 43 years old, and I've eaten egg yolks my entire life. I recently had a Coronary Calcium Scan performed on my heart, and my score came back a "1" on a range of 0 (No evidence of CAD) to 100 (Extensive evidence of CAD).

    This "new study" is just some MD student's thesis, as he is trying to graduate. What a load of crap!

      The point is that they followed over a thousand people. Your single experience says nothing about what anyone else might experience given the same behavior. But looking at thousands of poeple does show the odds of certain events happening. That's how research works.

      @raindeer - READ the STUDY. actually, just the abstact, because why would public research (which probably used gov money) be free to read???

      no one was 'followed'. this was, hey, tell me what you ate for the last 20 years. huge, ginormous difference.

      also, look at the margin of error, which is larger than the actual measurement.....

    This study was reviewed by the skeptical blog sciencebasedmedicine.org who found some serious problems with it...not sure how this ended up on CNN. link to the article here: http://www.sciencebasedmedicine.org/index.php/eggs-and-atherosclerosis/

    It is totally flawed to say this study shows that egg yokes are as bad as smoking because, for one thing, 'plaque buildup' is not the principal risk associated with smoking, and the biggest risks of smoking are other things like lung cancer. That's kind of like saying that cats are as almost as dangerous as cobras by comparing the size of their bites, without considering that cobras are poisonous and cats are not.

    This past year we got our own chickens and I have eaten more eggs than I ever did in my entire life. Eggs fried. Eggs scrambled. Eggs in quiche. Eggs benedict for brunch. You name the dish, we've eaten it. Dozens and dozens of eggs this year. Last year my cholesterol levels was 238, with my LDL at 143 and the HDL in the 40s. I just had it tested, and the cholesterol level is 181, LDL is 101, and HDL is 57. Was it the eggs?? You decide.

    It's one study. They looked at a thousand people, which isn't that many to draw a conclusion from.. They didn't look at what else the subjects were eating with their eggs. I'll wait for another study or two that will hopefully be more complete and conclusive than this.
    This happens all the time. Someone with a grant publishes premature findings from one small study in order to get a continuation of their grant money, so they don't have to go to work at a job outside their field. Six months later we read that another study has been done that found opposite results. An example among many was when we were warned that egg yolks were terrible for one's cholesterol. Then later another several studies came along that said, oops, actually eating a reasonable amount of eggs aren't bad for your cholesterol at all.

    Poorly designed study with no control group and using subjects already showing heart disease. Call me when a properly done study surfaces.

    But really, we're all going to die anyway, why deny oneself the joy of a nice omelet?

      I bet the only s*xual contact you've ever had has been with your little sister, against her will, pinned against a barn door where all the white trash lives. If you want to be the racst sack of dog filth you are, can you at least leave a bigoted comment on a story that has something to do with race? It may not make you look smarter, but it will certainly be more relevant you pathetic excuse for a human being.

    Cholesterol and saturated fat are precursors to the production of testosterone. NO wonder we have so many girlie men nowadays, they are told to avoid eating these things.

    Eggs are Embryonic...if you could care less, you might eat embryos...if you respect life, you might not eat embryos and dead meat, after you realize that it's not the right thing to do...change is good...focus on doing the right thing for yourself and creatures around you...

    I don't believe it. Folks have been eating yolks for ages. Only recently has this become an issue. Maybe it is due to all the garbage they feed to the chickens. Eat organic, range free, hormone free.

    The amount of cholesterol that has been reported in egg whites over the past few decades is now heavily disputed. And on top of that, there's not even any evidence that dietary cholesterol correlates to cholesterol in the blood. That's how it works with fat- guess who's gonna be fatter between someone who eats a few servings of olive oil everyday but limits sugar intake, vs. someone who eats next to no fat but drinks 3 sodas a day? So why is it so bad when someone eats something that's high in cholesterol but otherwise has a lot of nutrition?
