Eggs are a delicious approach to get a battery of B vitamins, nutrients and protein. And though there's some controversy regarding their effect on cardiovascular health, most specialists agree that a diet which includes eggs is a healthy one. One study even found that a breakfast of eggs, in comparison to cereal or no breakfast at all, helped individuals reduce cravings for sugary and fatty foods much later in the day. But given how ubiquitous this food actually is, it's astonishing how much we don't understand. So we've put together a listing of some little known facts about poultry eggs. Read on!
EGG YOLKS HELP BRAIN GROWTH
Egg yolks are one of the richest dietary sources of the B-complex vitamin choline, which is associated with better neurological function and reduced inflammation. Also, there's evidence that dietary choline helps with fetal brain growth when pregnant women eat it.
A dit rich in choline is also linked with, well, well-being. As Drew Ramsey, a psychiatrist who specializes in diet told HuffPost Healthy Living earlier this year, choline breaks down into bethane, which is used during the methylation cycle, which consequently helps generate "well-being" hormones (and neurotransmitters) like serotonin, dopamine and norephinephrine.
EGGS ARE A PERFECT PROTEIN
Eggs are the "gold standard" in regards to protein quality. That's because all of the protein found in an egg can be consumed and used by the entire body, Cynthia Sass, R.D., told Healthy Living in March.
THE AGE OF THE CHICKEN MATTERS
As it pertains to some measures of quality, the chicken comes before the egg. A study in Poultry Science (where else?) found that young chickens, age 28 weeks, and old chickens, 97 weeks, were more likely to produce eggs with low solids contents than were middle-aged chickens. "It may be more advantageous for egg producers and processors to make use of young and old fowl for table egg production and birds of intermediate age for liquid egg generation," wrote the researchers.
WHAT EGG YOLK COLOR REALLY MEANS
The deep yellowish or pale colour of your egg yolk doesn't measure healthfulness directly, according to the American Egg Association. Instead, it is indicative of a chicken's feed. Chickens which are fed grains and grasses full of carotenoids (like lutein and zeaxanthin) have more vibrantly yellow yolks, however that does not automatically translate to a more nutritious yolk.
It could measure chicken health, however: As Dr. Hilary Shallo Thesmar of the Egg Nutrition Center told Chow, free range chickens have access to a greater diversity of foods, which in turn makes them more likely to have stronger yellow yolks.
UNCERTAIN VS. CLEAR EGG YOLK
What makes for a muddy or clear egg white? It's the exact age of the egg. Old eggs have clear whites, while fresh eggs can have a milky, opaque look.
BROWN VS. WHITE EGGS: THERE'S NO DIFFERENCE
Shell colour is related to the breed of chicken--it really has nothing related to the healthfulness of the egg or the health of the chicken who laid it.
EGGS ARE GOOD FOR THREE MONTHS
Eggs are usually packaged within a week of laying, though USDA regulations allow them to be up to 30 days from the coop. The sell-by date needs to be within a month of the pack date, making the total shelf life of eggs about two months. But, according to the USDA, eggs might still be good from three to five weeks following the sell-by date passes, reports Yahoo.
