Eggs are one of the most nutrient-dense foods in existence. This article will discuss the health benefits of eggs, the nutrients they contain and their importance to your body.

Later on, I’ll share a bunch of great low-carb egg-based recipes.

5 Health Benefits of Eggs

In truth, I could list about 50 health benefits of eggs here. But in the interest of keeping this a little shorter in size, here are the top 5.

Health Benefit #1 – Eggs Are Extremely Nutrient-Dense

Eggs are an extremely nutrient-dense food.

One of the biggest problems with the modern diet is that far too many people count calories.

Calories can either be healthy or unhealthy depending on the food. So, counting total calories is meaningless as a determinant of how healthy a diet is.

In reality, we should be focusing on the nutrients we consume. Fortunately, if we count the nutrients in eggs, we see some impressive results.

Overall, eggs truly are nature’s multivitamin. They contain protein, healthy fats, vitamins, minerals and various antioxidants (1).

In fact, one egg provides all the nutrients to support new life for a chick. Eggs are an especially good source of choline, selenium, vitamin D and riboflavin.

All of these nutrients play a significant role in the health of our body.

  • Choline: vital for liver health and essential for our muscular and nervous systems (2).
  • Selenium: has an antioxidant role in the body and protects against free radical damage, involved in DNA production and thyroid function (3, 4).
  • Vitamin D: one of the most critical nutrients for overall health. Essential for an optimal skeletal system, and helps regulate inflammation and protect DNA (5, 6, 7).
  • Riboflavin: otherwise known as vitamin B2, Riboflavin is necessary for energy production, metabolism, and protecting the body against free radicals (8, 9, 10).

Key Point: Eggs are virtually unmatched when it comes to nutrient density. While some foods provide a large amount of a nutrient, eggs provide a moderate amount of almost everything.

Health Benefit #2 – Eggs Help Reduce Heart Disease Risk

Eggs Help Reduce Heart Disease Risk Factors

Another of the health benefits of eggs is that they can help protect against heart disease. In contrast to what you may have heard, this might surprise you.

The way they do this is through lowering several cardiovascular risk factors.

  • Eggs contain several heart-protective nutrients, especially vitamin D and the various B vitamins (11, 12, 13, 14).
  • Eggs help raise high-density lipoprotein levels (HDL) and in many cases decrease triglyceride levels (15, 16).
  • Egg consumption leads to a less atherogenic (heart-disease-promoting) cholesterol profile (17, 18).

Additionally, the modern diet is so low in many nutrients due to widespread deficiencies. As eggs are one of the most nutritious foods we have, a few eggs go a long way to meeting nutrient requirements.

Key Point: Contrary to what you may have heard, eggs have a range of beneficial effects on heart disease risk factors. Consumption of eggs relates to an overall healthier cholesterol profile.

Health Benefit #3 – Eggs Are a Dietary Source of Choline

Eggs contain choline

If you haven’t heard of choline before, then you need to look into it. Choline is a relatively unknown essential nutrient that’s desperately lacking in our modern diet.

In truth, the choline content is one of the most important health benefits of eggs. As an example, not getting enough choline is associated with:

  • Fatty liver disease – studies show that choline deficiency plays a prominent role in the development of fatty liver disease (19).
  • Increased DNA damage – as choline levels lower, DNA damage appears to increase (20)
  • Diabetes – diets low in choline seem to promote weight gain and type 2 diabetes (21).

Why Are We Deficient in Choline?

Specifically, we are deficient in choline because we developed a fear of fat and cholesterol. Regarding choline, the only two dietary sources of any real note are liver and egg yolks.

As a result of dietary guidelines to limit fat and cholesterol, many people started avoiding liver and only eating egg whites. This trend had a disastrous effect on our health as a society.

Instead of eating nutrient-rich foods, the average person instead turned to low-fat refined foods.

Basically, to consume enough choline to have adequate amounts available, it’s essential to eat eggs and/or liver.

As many people find it difficult to eat liver, here are some tips to make it easier.

Key Point: Eggs are one of the only dietary sources of choline. Deficiency of this important nutrient can cause a wide range of health problems including diabetes and even DNA damage.

Health Benefit #4 – Eggs Are Beneficial For Eyesight

Eggs Are Beneficial to Eyesight

Another health benefit of eggs is that they are great for eyesight. And if you’re thinking about vitamin A, then there’s far more to it than that.

But now that I’ve mentioned it – let’s start with vitamin A. Eggs provide a great active source of this nutrient in retinol form.

There are two types of vitamin A:

  • Retinol – this is a bio-available form of vitamin A that can be used directly by your body. We can find it in animal foods; egg yolks, liver and dairy products. Retinol is the best form of vitamin A because no conversion is needed.
  • Provitamin A carotenoids – plant foods contain carotenoids, and the most famous of these is beta-carotene. Provitamin A cannot be used directly by the body and must first metabolize into retinal.

Therefore, one of the biggest health benefits of consuming eggs is that they supply pre-formed vitamin A.

Additionally, eggs also contain a variety of health-promoting antioxidants that help improve eyesight.

Two of these include lutein and zeaxanthin:

  • Lutein helps protect against macular degeneration and cataracts. Unfortunately, macular degeneration is a growing problem in the western world and ultimately leads to blindness (22).
  • Higher plasma concentrations of zeaxanthin also protect against macular degeneration, while lower levels increase risk factors (23, 24).

Key Point: Eggs contain a wide range of beneficial compounds for eyesight. This helps protect against macular degeneration.

Health Benefit #5 – Eggs Are a Good Source of Vitamin D

Eggs Are a Good Source of Vitamin D

In modern times, vitamin D deficiency is rampant, and it’s having a disastrous effect on our health.

If you were unaware, vitamin D deficiency has links to a higher risk of almost all chronic disease. For example; cancer, Alzheimer’s, type 2 diabetes and cardiovascular disease (25, 26, 27, 28, 29).

As you may have heard, sunlight is easily the best way to get vitamin D. This is down to the relative ease and also the fact that sunlight provides many additional health benefits.

However, most people in the world cannot get adequate vitamin D from the sun in long, dark winters. As a result, good food sources of vitamin D are essential for health.

Another of the health benefits of eggs is that they supply a decent amount of vitamin D. One large egg provides around 11% of the recommended intake (30).

In other words, a 4-egg omelet would provide almost 50% of the recommended figure.

Fatty fish such as salmon and mackerel are probably the best sources of vitamin D, but every little helps.

Key Point: Eggs are one of the best dietary sources of vitamin D.

Nutrients in an Egg

What Are the Nutrients in Eggs?

When it comes to nutrition, eggs are loaded with nutrients. As the title of this article says, they truly are nature’s multivitamin.

But there are not many calories in eggs; a large egg contains only 77 calories.

Here are the vitamins and minerals supplied in one large egg.

Macronutrients

Firstly, here are the macronutrients in one large egg:

  • Protein – 6.29g
  • Fat – 5.3g
  • Carbohydrate – 0.56g

Vitamins

Here are the major vitamins in one large egg:

  • Riboflavin (Vitamin B2) – 41% RDA
  • Vitamin B12 – 25% RDA
  • Pantothenic Acid – 19% RDA
  • Vitamin A – 16%
  • Folate – 15%
  • Vitamin B6 – 8%
  • Vitamin E – 7%
  • Thiamin – 6%

Minerals

Here are the major minerals in one large egg:

  • Selenium – 60% RDA
  • Phosphorus – 23% RDA
  • Calcium – 7%

As you can see, eggs are incredibly nutritious. And if you have three or four for breakfast, then you can triple or quadruple those nutrient numbers.

Compared to a box of ultra-processed cereal, eggs are the much healthier choice. Additionally, eggs are great for satiety, so you won’t be craving snacks halfway through the morning (31, 32, 33).

Key Point: Eggs are full of vitamins, minerals and antioxidants. They are one of the most nutrient-dense foods in the human diet.

The Best Type of Eggs

Pastured Eggs Are the Best Type of Egg

Most eggs look similar, but they can be very different in regard to nutritional value. To get the full health benefits of eggs, we need to consider the type of egg we eat.

The lifestyle of the hen that laid the egg is a key determinant of the nutrients present. For example, eggs from pasture-raised chickens have an overall healthier nutrient profile.

In one study, researchers compared the ratio of vitamin A, E, as well as fatty acids in pasture-raised hens compared to caged hens.

The pasture-raised hens were free to forage in grasslands for their own food. On the other hand, the caged hens ate standard commercial feed.

These were the results:

  • Compared to the eggs from caged hens, pasture-raised hen eggs had double the amount of vitamin E.
  • The concentration of vitamin A was 38% higher in the in the pastured hen’s eggs.
  • Eggs from pastured-raised hens had 2.5x the amount of total omega-3 fatty acids.
  • Pasture-laid eggs had less than half the ratio of omega-6:omega-3 fatty acids (34).

It’s clear to see that the health benefits of eggs from pasture-raised hens are much greater. But health shouldn’t be the only consideration.

After all, an animal is a living creature with thoughts and feelings. Do you want to eat eggs from a hen who lived a life stuck in a cage? I know I don’t.

Key Point: Choosing eggs from pasture-raised hens is a much healthier option: both for you and the animal.

Are Eggs High in Cholesterol?

Are Eggs High in Cholesterol?

First of all, the answer is yes – eggs are very high in dietary cholesterol. But it’s important to realize that dietary cholesterol is not harmful.

Despite being demonized for decades, a vast array of evidence shows that dietary cholesterol has very little relation to cholesterol in the blood (35).

In fact, eating dietary cholesterol from eggs appears to be good for you. In a recent study, 28 male participants ate eggs three times per day over 12 weeks.

All in all, the results were very promising. High-density lipoprotein (HDL) raised in each participant, while all metabolic syndrome risk factors decreased (36).

Interestingly, there is also an earlier study back from 1991, but this one is unique and worth mentioning. As part of this study, researchers examined an 88-year-old man who eats 25 eggs per day.

To summarize the results, he had normal cholesterol readings and was virtually free of atherosclerosis (arterial plaque) (37).

I’m not saying to eat 25-egg omelets, but three or four eggs per day are perfectly fine.

To emphasize: don’t throw away the yolk because that’s where most of the nutrients are.

Key Point: Don’t fear dietary cholesterol – the vast majority of studies show that is has very little impact on cholesterol levels. Also, you’ll be missing out on the health benefits of eggs if you only eat the whites. The yolk is the most nutritious part.
