A friend asked me to look into the benefits of raw egg yolks before she started eating them. My family consumes raw egg yolks in our smoothies
without any adverse effects. The eggs we use are from a small local farmer I
have come to know very well. She has pasture raised, hormone free, antibiotic
free, bug eating, sun loving chickens. The eggs are exceptionally fresh
(literally only a couple of days old at most by the time that I purchase them).
I do not consume eggs from the large health food stores like Whole Foods
because I do not know the conditions in which the chickens were raised, how the
eggs are prepared for sale (including pasteurization), and how old the eggs
are. As for the whites that are unused when I make smoothies, I save them (no
more than two days) and put them into a nut flour recipe, with two whites equaling
one egg (see recipes link for nut flour use and smoothies).
Benefits
Raw egg yolks have high levels of nutrients and are a
healing food. Cooking egg yolks reduces the benefits. There are many, many
internet sources citing the benefits of raw egg yolks, but many of them do not
have the science and depth of knowledge to back them up the way that Sally
Fallon, author of Nourishing Traditions and President of the Weston A.
Price Foundation www.westonaprice.org,
does.
Discussed below are some of the nutrients in and
benefits of consuming eggs, including raw yolks, all excerpted from Nourishing
Traditions. There is much more information in Nourishing Traditions than
what I am excerpting below, and to receive the full benefit of Sally Fallon’s
research, you should read it independently.
Eggs have provided mankind with high-quality protein
and fat-soluble vitamins for millennia. Properly produced eggs are rich in just
about every nutrient we have yet discovered, especially fat-soluble vitamins A
and D. Eggs also provide sulphur-containing proteins, necessary for the
integrity of cell membranes. They are an excellent source of special long-chain
fatty acids call EPA and DHA, which play a vital role in the development of the
nervous system in the infant and the maintenance of mental acuity in the adult –
no wonder Asians value eggs as brain food. Egg yolk is the most concentrated
source known of choline, a B vitamin found in lecithin that is necessary for
keeping cholesterol moving in the blood stream. (p. 436)
Vitamin A also acts as an antioxidant, protecting the
body against pollutants and free radicals, hence against cancer. Vitamin A
stimulates the secretion of gastric juices needed for protein digestion, plays
a vital role in building strong bones and rich blood… Dr. Price discovered that
the diets of healthy isolated peoples contained at least ten times more vitamin A from animal sources than found in the
American diet of his day [early 1900s]. The high vitamin A content of their
diets insured them excellent bone structure, wide handsome faces and plenty of
room for the teeth and ample protection against stress of all types. It is best
to obtain vitamin A from natural sources like yellow butter, egg yolks, organ
meats, fish, shellfish and cold liver oil (p. 37)
Why not Consume Raw Egg Whites?
The advice of Sally Fallon has served my family
exceedingly well, and I will rely on it again. This is what Sally has to say on
the Weston A. Price website:
We agree that it is fine to consume plenty of raw egg
yolks, a custom found in many traditional diets, but consumption of raw egg
whites on a regular basis can lead to digestive problems. The problem is… that
raw egg whites contain enzyme inhibitors that can interfere with protein
digestion. Whole eggs should be cooked--and it is fine to cook them any way you
like them.
What About Raw Egg Yolks
and Salmonella?
Sally Fallon states in Nourishing
Traditions: “The blame for such problems lies squarely on crowded
production methods that require extensive use of antibiotics in feed. Eggs from
pasture-fed hens pose no danger provided they have been properly refrigerated”
(p. 37)
A review of the U.S. Department of Agriculture’s (USDA)
most recent research underscores that the problem is with factory farmed
chickens, because the USDA only studies eggs from undernourished,
overmedicated, never eaten a bug or seen the sun, living in filthy conditions
chickens whose eggs have to be sterilized because of the terrible conditions
under which they are produced http://www.fsis.usda.gov/Science/Risk_Assessments/index.asp#eggs.
How Many Eggs a Week Does My Family Eat?
We eat about three dozen a week. We use them for baking,
smoothies, and a scrambled egg or omelet dinner. We have been eating this many
for almost eight months. When we began, I wondered how all of these eggs would
affect my health. Check out my Cholesterol post: Victory
- Cholesterol. You can also read other posts reporting on how my family is
excelling.
Still Need More Information?
As with any idea about which you are skeptical, do your own
research to ensure that you making the best decision for you.
Salmonella is as natural as it comes. You can find it in the earth and in bugs. That's the same earth and bugs that the backyard chickens scratch in and eat.
It doesn't really matter if you know the chickens intimately. Bacteria is bacteria.

Hi,
I was reading your site and was wondering if you would be open to pasteurized shell eggs if you knew more about the company and where the eggs came from. National Pasteurized Eggs is currently the only patented FDA, USDA, and military approved eggs.
These eggs are pasteurized, the process is explained on their website (safeeggs.com), to remove salmonella bacteria making it safer to consume raw eggs. Fresh eggs may not contain as much bacteria, but are still at risk for bacteria and illnesses since they have not been pasteurized.
National Pasteurized Eggs' brand Davidson's Safest Choice can be found in grocery stores and provide a lot of information on their website. They are sold to many food service institutions and many hospitals and health care facilities choose to serve their eggs.
For more information please feel free to contact me (krhee7@gmail.com) or visit their website.
Thank you

I appreciate the comments sent in earlier today. They result in more research and a great discussion.
I agree, Salmonella is as natural as it comes. Regarding knowing how well the chickens are raised and the eggs collected, I believe that is important because the consumer is taking responsibility for ensuring that the food is the best and safest quality.
When considering every major salmonella outbreak (or other food borne illness outbreak), including the most recent salmonella contaminated peanut butter-related incident that this past month has sickened 600 people and killed 9, mass production and mass treatment of food are most often the culprits. Taking the peanut butter incident one step further, their Texas facility was shut down due to rat feces in the ceiling that was being sucked into the ventilation and spread throughout the food processing area and into the products people were consuming.
Regarding pasteurization and National Pasteurized Eggs, if other local sources of eggs were not available, I would consider those. That said, I try to avoid any kind of factory food. I try to avoid pasteurized eggs for my family, because pasteurization kills some of the beneficial properties of eggs, just as pasteurization kills the beneficial properties of milk (we are raw milk consumers, too).
Bottom line is that natural, unprocessed foods have been consumed by humans and their ancestors for over 250,000 years. Recent processing and denaturing has become necessary in some instances because the natural cycle has been corrupted, making food unfit for consumption. Many processed foods (many of which are fake, anti-nutrient "foods" have also made people more and more ill. Humans have not evolved quickly enough to accommodate all of the unnatural food changes, particularly in the last 150 years or so.
Finally, people who consume unprocessed, healthy, nutrient dense food are less likely to be sickened by salmonella and other diseases.
The simpler the better is a concept my family does our best to live by.
