Eggs Yolks and Bad Science

You have got to love bad science. And the media.

A couple of years ago, I finally stopped fearing the whole egg. For years I ate nothing but egg whites. My breakfast of champions 10 years ago was 1/2 cup of oatmeal, 1 cup of water, and four egg whites in the microwave for a couple of minutes. Boom. Healthy as an ox. I’ve advised clients to give up their yolks, Or at the very least, do one yolk and whites if they couldn’t do so.

It took me a while to wrap my head around the fact that I can actually eat the whole egg. Wait? It’s healthy for me? The cholesterol in eggs do not cause high cholesterol and plaque buildup? Today, I enjoy fried eggs with no feelings of guilt.

I now advise clients that they can enjoy the delicious whole egg. Some told me that their palates were so used to eating the whites, and they were so stuck in thinking they were forbidden that they’d never go back.

I did though. And I stand by my decision. Egg yolk lovers unite!

This study stating that we should go back to fearing the yolk  has many holes and discrepancies.It also has many people fearing the whole egg again.

I mean, eating eggs is almost as bad as smoking!??? Please!

In my opinion it’s a poorly done study that the media is jumping on for shock value and headlines.

Headline:

“Eggs Yolks Almost as Bad as Smoking”

If you read the study what is ACTUALLY says is:

“May increase carotid plaque build-up.”

If you look at the data the strongest correlation is between plaque buildup and age. Not egg consumption and plaque buildup.

It’s a correlation study. Correlation does not mean causation. Eggs do not “cause” heart disease. This study simply takes a look at the correlation between the two. A study doesn’t just have to show causation, it also has to show that it’s plausible.

There seems to be a huge discrepancy in the data regarding age, amongst other things:

  • No data about overall diet: processed foods, sugar, trans fats, or wheat.
  • How many actual healthy foods (vegetables and fruit) were consumed by participants. How much do they eat?
  • Lifestyle was not a factor: how much do the participants exercise? What are their lifestyles like? Are they active at all? Do they work a desk job? Or do they work on an oil rig?
  • Stress: That goes along with lifestyle, but I thought I’d give it it’s own number. How much stress do these participants have in their lives?
  • How much do they weigh? What is their waist-hip circumference? That plays a huge role in increasing the risk of heart disease

The doctors that performed the study were funded by and receive compensation from multiple Pharmaceutical companies whom manufacture lipid-lowering drugs. They also have a vendetta against eggs. For which they have already been called out for.

This was also a “self-study” Meaning the participants just reported back to the doctors. No controlled environment.

This article debunks the study, and even goes into the science behind how the fat in an egg is digested. It’s far fetched that egg yolks are being injected directly into your arteries.:

“The chain length of fatty acids determines how they are transported out of the digestive system. If a fatty acid has fewer than 12 carbon atoms, it will “probably travel through the portal vein that connects directly to the liver. If the fatty acid is a more typical long-chain variety, it must be reformed into a triglyceride and enter circulation via the lymphatic system.”[i] Egg yolks thus have no short chain fatty acids that may even head off in the portal vein to the liver (not that this should cause concern anyway). The longer chain fats (saturated and unsaturated) are packaged into chylomicrons, released into the lymphatic system and they glide from there into the blood stream to carry the vital nutrients around the body to do their vital work.”

You will find egg lovers and healthy gurus alike clearing the name of our beloved egg.

Have your eggs and eat them too!

Remember to stick with organic, pasture-raised  eggs. The ones where the hens roamed free and ate bugs and seeds…not GMO soy and corn.

Here’s Why:

  • the egg yolk contains all of the nutrition in the egg (healthy fats and vitamins, minerals)
  • you are what you eat…you are what the chicken eats. To get the most of the nutrition in the egg, buy the most nutritious eggs. From your farm if possible!
  • Caged vs. Free-Range. If you saw the condition of the chickens from the cheap commercial grocery store eggs, you’d hopefully think twice and spend and extra buck on organic or make a trip to the farm.
  • In addition to being better from an environmental perspective, free-range eggs are also nutritionally superior, as demonstrated in Mother Earth News’ 2007 egg testing project. Compared to official U.S. Department of Agriculture (USDA) nutrient data for commercial eggs, eggs from hens raised on pasture may contain much more Omega-3 fatty acids, 7x more beta carotene and 2/3 more Vitamin E!

And as far as that junk study goes…do I even need to get into why smoking is bad? It doesn’t even compare.

If you want to take a look an actual controlled study, which was reported by the media, go back and watch this 60 minutes report on how toxic sugar is. They took YOUNG, healthy participants and actually placed them in a controlled environment. They controlled what they ate, their activity levels and regularly collected data from each participant (blood pressure, bloodwork, etc).The data, in these young teenage participants actually showed how sugar and heart disease and other health problems were linked! If there ever was any one food  you should cut out, that “food” would be sugar.

    I have a friend that insists that smoking isn’t bad for you. That all the data is a huge conspiracy. I guess people are going to believe what they’re going to believe. I worry about eggs because of what they feed the chickens, not about cholesterol.

    I sometimes eat egg white items, but in general, I don’t avoid yolks. People sometimes call me out on, “oh, you’ve eaten 2-3 eggs today, watch your cholesterol” when they are chugging lobsters and shrimps. My cholesterol is actually on the lower side of normal, even though a couple of people in my family have/have had high cholesterol issues (I think seafood related because they are super thin). Worse was this story about egg yolks being worse than cigs… uhh yeah, my smoking uncle (RIP) definitely didn’t die of egg yolks.

    Just found your blog – great breakdown of why this research stinks. I raise my own chickens and I can see the beautiful yellow beta-carotenes they get from eating grass in yolks that are deep orange – not yellow.
    After juicer Jack LaLanne pushed the whites I had to do a lot of work convincing my husband. But now he scarfs them up too (great with avocado – another no-no food that’s good for you and weight-loss!)

    I’ve written about why fats and cholesterol are bad is such a big fat myth right here: http://fitfamilytogether.com/is-fat-healthy-big-fat-myth-dispelled

    Funny how one study showed people with high cholesterol lived longer! (Don’t know the details to assess the research, but worth inserting in the discussion!)

    Thanks for posting. I am always on the fence about whole egg vs. only egg whites, but getting the stuff in a container seriously grosses me out, and I feel awful about wasting a whole yoke, also I think it is the most delicious part. Over time i have become a huge advocate of the whole egg, regardless of what people say, nature made eggs and it isn’t like they have been processed to death so really how bad can they be for you!?

    ever since we started eating eggs a year ago we could not wait to eat the yolks!! the yolks are the best part. We have two whole eggs everyday!!! And love it, sometimes we want a third one. We still occasionally have just egg white meals, just because we already had 2 whole eggs and we still don’t do that well with a lot of meat. So eggs are our go-to protein lately.

    We do have a question we get local eggs when we can, but if do get them from the store we get cage free, thoughts? There are organic available but they very expensive. Do you like cage free are okay? Would love to hear your thoughts!

      free-range are definitely better if you can’t go to a farm or get organic. As long as the free-range is not in a coop (just saying free-range because not in cages, but still packed in a small area). I am not 100% sure but as far as I know it’s only a step below organic!

    I just watched the 60 minutes interview you posted. I’m going to watch the doctor’s youtube video. My oncologist told me years ago that he believes cancer tumors feed off of sugar. The docs in this interview agreed.

    I do feel like sugar is addictive like cocaine. It’s proof when I go withdrawals when I limit it. I still need to do a better job.

    I’m always confused on eggs. The studies change every year on this. My thing is nobody eats a crapload of eggs even in a week. A lot of people with digestive problems like IBS find eliminating the yolks are easier on the stomach, but other than that, it goes along with the everything in moderation huh?

      Yes, moderation. Eggs ARE an allergen food, so people with GI issues and allergies, etc can’t eat ton of them. But in regard to it causing heart disease, no. Just no.

      Yes, cancer cells do feed off of sugar. It’s so hard to tell a cancer patient who is nausea and doesn’t like many things that they can’t have their carbs though. It’s a scary thing. That is another reason I am really eliminating sugar. The statistics scare me.

      It is very addictive, and you are doing great. Just keep finding real foods, healthy fats and protein to satisfy you and you will find you eat less and less sugar/starchy carbs

    Great post! I just read that article too, and completely agree with you. Like most studies, it seemed they had a pretty clear agenda. Westerners generally eat way too much protein (which creates a host of problems in you body), but when eaten in moderation with a healthful diet eggs are a great source of Omegas (brain food!) and protein.

    I absolutely agree that sugar is the one to cut out (except for the small amount found naturally in nature in fruit). I know I always feel better on a lower sugar, higher protein and fat diet focused on vegetables and fruit. 🙂 That’s pretty crazy about the study. I’ve found a lot of science experiments prove things in that kind of method — a faulty, not controlled way. The way they did the sugar one that you mentioned is the REAL way to do it.
