Health Benefits Of Eating Raw Eggs And It Complication
Health Benefits Of Eating Raw Eggs And It Complications
They're super-trendy, but are they worth the risk?
Raw eggs have been longtime staples of quite a few traditional make-at-home recipes, from mayonnaise to Caesar dressing. But lately, more and more of them are being used in unconventional ways.
Weightlifters and athletes with
intense training schedules may crack them into smoothies or oats for a
protein boost, while others may whisk them into cocktails or hot
chocolate just for the heck of it.
But we
were all taught to resist licking the bowl of cake batter as kids (as
tempting and difficult as it is!), making the allure of Team Raw a bit
questionable. What do raw eggs really bring to the table? We asked
nutritionists to weigh in on both the nutritional value and safety of
eating raw eggs. Here's what they had to say:
NUTRITION
You’d
be surprised at how many nutrients are packed into a tiny eggshell.
Just one raw egg contains three grams of protein; vitamins A, B2, B5,
B12 and E; choline, a mineral that’s essential for brain function;
lutein and zeaxanthin, antioxidants that keep our eyes healthy; and so
much more. Heating up a raw egg does ever-so-slightly diminish the
amount of its nutrients, but the nutritional difference between a raw
egg and a cooked one is so small that it’s flat-out insignificant.
“Raw eggs contain an abundance of
protein and great deal of nutrients that can help support brain, immune
and nervous system function,” says Tara Gidus Collingwood, R.D.N., team dietician for the Orlando Magic and nutrition consultant for UCF Athletics. “However, practically none of these nutrients are lost or changed when the egg is cooked.”
So,
as far as nutritional value goes, raw and cooked eggs are pretty much
tied. But cooked eggs do have a leg up on the competition when it comes
to the digestion of those nutrients. One study published in The Journal of Nutrition
revealed that our bodies only absorb 50 percent of an egg’s protein
when we consume it raw, versus 90 percent when we consume it cooked.
“Another concern is with biotin absorption,” says Heather Mangieri, R.D.N., spokesperson for the Academy of Nutrition and Dietetics and author of Fueling Young Athletes. “One
of the egg proteins, avidin, when raw or undercooked, can bind with
biotin, [a B-vitamin], making it unavailable for absorption. The only
way to make sure the biotin in the egg yolk isn’t inhibited is to make
sure the egg is fully cooked.”
In
other words, unprepared eggs are not only less digestible, but they also
cause you to miss out on most of that high protein and vitamin
content—so there’s really no point in dropping them into your smoothie
after all. If you’re looking to build muscle, you’ll get a much bigger
punch out of your meals and drinks if you stir in some high-quality
protein powder rather than raw eggs.
HEALTH RISKS
Here’s
a little lesson in biology: When a chicken lays an egg, the egg exits
the body through the same opening that the chicken’s poop does. So right
off the bat, eggs are prone to being exposed to harmful bacteria, like
salmonella, which can be carried on the surface of the eggshells or
absorbed into the egg itself. Contamination can also be influenced by
factors like how old and how large the chicken flock is, what the
chickens are eating, how much stress the chickens are under, and how
clean the chickens’ environment is, among others.
While
the actual risk of an egg carrying salmonella is fairly low (only one
in 20,000 eggs in the U.S. is contaminated, according to Mangieri), it’s
still not worth taking your chances on—as anyone who has actually
experienced salmonella will tell you. “The main risk of consuming
raw or undercooked eggs is salmonella infection, which causes food
poisoning symptoms such as stomach cramps, diarrhea, nausea, fever and
headache,” says Lauren Antonucci, R.D.N., a
registered dietician and board- certified sports dietician, and
owner/director of Nutrition Energy, a nutrition consulting practice in
New York City. “These symptoms may appear within the first six to 48 hours of consuming raw eggs and can last up to seven days.”
The
United States Department of Agriculture (USDA) clearly advises against
the consumption of any type of raw eggs too—and that includes brown,
white, organic, free-range, and non-GMO. They also explain that people
with underdeveloped or compromised immune systems—such as children, the
elderly, pregnant women, and those suffering from cancer or autoimmune
diseases such as AIDS—are especially susceptible to salmonella infection
and can experience even more dire consequences. For example, the
bacteria can cause uterine cramps and infection in women during
pregnancy, which can lead to premature birth or fetal death.
The only way to ensure the eggs you’re consuming are salmonella-free is to cook them thoroughly: “During the cooking process, heat to a certain temperature will destroy the bacteria, making it less of a threat,” says Lisa Moskovitz, R.D., CEO of The NY Nutrition Group,
a private New York-based nutrition practice. The American Egg Board
says that bringing eggs to an internal temperature of 160 degrees
Farehnheit will kill almost any germs they might be carrying.
Now if you absolutely must
consume raw eggs for one reason or another, despite warnings from the
experts, there is one thing you can do to minimize your risk of
infection: Opt for the pasteurized variety. “Pasteurized eggs are the safest choice when it comes to eating raw eggs,” says Antonucci. “During the pasteurization process, many bacteria and microorganisms commonly found in raw eggs are eliminated.”
That’s because the eggs are pasteurized by being heated to 140 degrees
Fahrenheit for about three and a half minutes, and most bacteria can’t
survive that temperature. Just make sure you keep the eggs refrigerated,
don’t eat any eggs that have passed their expiration date, and toss any
cracked eggs in the trash. But because the heat of the pasteurization
process infinitesimally reduces the amount of nutrients in the egg just
like the cooking process does—and since our bodies don’t fully absorb
the nutrients in raw pasteurized eggs either—then you might as well go
ahead and cook them anyway.
Considering the mounting evidence in the trial of raw vs. cooked, here’s the experts’ final verdict: “There is absolutely nothing magical or superior about raw eggs that would make them a beneficial addition to anyone’s diet,” says Mangieri. “You
can never say with 100-percent certainty that consuming raw eggs is
safe. I advise against the consumption of raw eggs in any form.”
