7 Things You NEVER Knew About Eggs

Have you ever stopped mid-crack to marvel at the humble egg? Probably not. But, if eggs could talk, they'd tell you a lot more than just "I'm breakfast."

You might think you know your way around an omelet or scramble, but so much about eggs remains unexplored. Did you know that most US chickens are still confined to cages? Or that organic egg production is a mere drop in the bucket?

Then there's nutrition - who knew yolks were such nutritional powerhouses with vitamin A and protein packed into their sunny centers? Not forgetting choline either; this unsung hero does wonders for our liver health and brain function.

We're busting the myth that eggs lead to high cholesterol. Plus, let's not forget about vitamin A. As it turns out,

The State of Egg Production in the United States

Let's crack open some surprising facts about egg production. A staggering 65.9% of chickens in the US are mostly caged for their precious eggs.

The Prevalence of Caged Chicken Farming

Farmers often choose cages to maximize space and productivity, which can lead to questions about animal welfare. To get an idea, imagine trying to live your life confined within the boundaries of a sheet of letter-sized paper - that's what it’s like for these birds.

Cage-free farms exist, but they're not as common as you think.

The Minority Status of Organic Egg Production

Organic farming takes things further by using natural methods and avoiding synthetic substances. However, only 5.8% of all chicken and egg production is organic in America. This could be because it requires more resources, such as land and time.

Eggs aren't just breakfast food anymore; they're subjects in debates over ethics, sustainability, nutrition, and economics.

The Nutritional Powerhouse that is the Egg Yolk

Think of egg yolks as nature's multivitamin. They're packed with various essential nutrients, including vitamin A and protein.

The Vitamin A Richness of Egg Yolks

Egg yolks are a remarkable source of vitamin A. According to research, they stand second only to cod liver oil in terms of retinol content - the form your body prefers. So next time you crack an egg open for breakfast, remember it's helping keep your vision sharp.

Protein Content Comparison Between Yolk and White

You might think the white has all the protein, but guess what? The yolk contains more protein per volume. That’s right - if we compare ounce for ounce, yolks take home the gold medal in this race.

The Concentration of Vitamins and Minerals in Egg Yolks

Beyond just vitamin A and protein, egg yolks boast an impressive array of other vitamins and minerals, too. While exceptions like B2 (riboflavin) and B3 (niacin) exist, most others have made their home within that golden center.

Choline - The Underappreciated Nutrient in Eggs

Ever wonder what makes eggs so unique? Beyond their versatility and deliciousness, they pack a punch of essential nutrients. One often overlooked nutrient is choline.

This mighty molecule is abundant in egg yolks, making them the top food source for choline. It's like discovering your favorite cozy sweater also happens to be made from the softest cashmere.

Choline not only plays a critical role in liver health, but it’s also crucial for brain function.

Imagine your body as a bustling city where every organ has a job. Consider Choline, an all-around handyman who helps keep things running smoothly in this scenario.

Specifically, it supports our 'liver department' by promoting normal liver function and preventing fatty liver disease. This study suggests adequate dietary choline intake may help maintain healthy liver function.

In addition to helping at the 'liver department,' it does double duty supporting our ‘brain headquarters.’ A study showed that higher dietary choline intakes were linked with cognitive benefits, including improved memory and processing speed.

Debunking Myths about Eggs and Cholesterol

The egg, a breakfast staple for many, has often been shrouded in controversy. One of the most prevalent myths is that eggs raise cholesterol levels. But let's crack this myth open.

The Lack of Evidence Linking Eggs to High Cholesterol

Many folks are concerned that eating eggs may result in heart issues due to their cholesterol levels. However, research suggests otherwise.

A study published by The American Journal of Clinical Nutrition found no significant link between egg consumption and heart disease or stroke in healthy individuals. This means you can enjoy your sunny-side-up without worry.

Eggs are nutritional powerhouses packed with protein vitamins A & D, among others - not something we should ban from our plates based on outdated beliefs. So go ahead and scramble, poach, or boil away guilt-free.

The Importance of Vitamin A for Health

Vitamin A plays a pivotal role in maintaining our health. Let's dig into why it's vital, especially for vision, immune function, and skin health.

Vision Boost with Vitamin A

Are you aware that vitamin A is essential for excellent eyesight? It helps keep the cornea clear - that’s the outermost layer of your eye. Lack of vitamin A can lead to night blindness.

Bolstering Immune Function

Your body uses vitamin A to produce white blood cells – those handy little warriors fighting off bacteria and viruses. So, more vitamin A equals stronger immunity.

Skin Health & Vitamin A

Ever wondered what keeps your skin smooth and healthy? Yep, it’s also down to vitamin-A-rich foods like eggs or carrots. They help speed healing processes and prevent breakouts by reducing excess oil production.

Remember this golden rule: Ensure you consume adequate vitamin A daily to reap its benefits. Your body will be grateful later on.


Let's return to those surprising facts about eggs we've cracked open. Cage farming still dominates, while organic production is only a tiny player.

The yolk - oh, the yolk! It's not just for color in your morning scramble; it packs a punch with vitamin A and protein. And don't forget choline, an unsung hero who helps our liver and brain.

We also cleared up some misconceptions. Eggs causing high cholesterol? That myth got scrambled today!

Last but certainly not least, remember Vitamin A’s vital role in vision, immune function, and skin health.

Next time you crack open an egg for breakfast or baking – think of all these fascinating truths hiding within its shell!
