Pastured vs Omega-3 vs Conventional Eggs — What's the Difference? (2024)

Eggs are one of the most nutritious foods you can find.

But depending on what the hens they came from ate, their nutritional value can differ greatly.

This article looks at the difference between conventional eggs, omega-3-enriched eggs and pastured eggs.

Different Types of Eggs

There are several different types of eggs, and their nutritional contents vary.

This depends on how the hens were raised and what they were fed.

  • Conventional eggs: These are your standard supermarket eggs. The hens that lay these eggs are usually fed grain, supplemented with vitamins and minerals.
  • Organic eggs: The hens were not treated with hormones and received organic feed.
  • Pastured eggs: Chickens are allowed to roam free, eating plants and insects (their natural food) along with some commercial feed.
  • Omega-3-enriched eggs: Basically, they’re like conventional chickens except that their feed is supplemented with an omega-3 source like flax seeds. May have had some access to the outside.

There are other terms that overlap with those mentioned above. These include free-range and cage-free eggs, which may or may not be any better than conventional eggs.

Free-range means that the hens have the option of going outside.

Cage-free simply means that they aren’t raised in a cage. They could still be raised in a smelly, dirty and overstuffed hen house.

Summary

Many different terms are used to describe eggs. These include organic, omega-3-enriched, pastured, free-range and cage-free eggs.

Conventional vs Omega-3 Eggs

A study compared the fatty acid composition of three types of eggs: conventional, organic and omega-3-enriched (1).

  1. Omega-3 eggs had 39% less arachidonic acid, an inflammatory omega-6 fatty acid that most people eat too much of.
  2. Omega-3 eggs had five times as much omega-3 as the conventional eggs.
  3. There was very little difference between organic and conventional eggs.

It was clear that hens fed omega-3-enriched diets laid eggs that were much higher in omega-3s than conventional eggs.

This is important because most people eat too little beneficial omega-3s.

Unfortunately, this study didn’t measure other nutrients, only the fatty acid composition.

Summary

Hens that get omega-3 supplements lay eggs that are much richer in omega-3 fats than conventional eggs. Choose omega-3-enriched eggs if you don’t get enough omega-3s from other sources.

Conventional vs Pastured Eggs

In 2007, Mother Earth News magazine decided to test the nutritional value of pastured eggs from 14 different farms.

They were measured in a lab, then compared to the USDA standard conventional egg.

As you can see, eggs from pastured hens were more nutritious than the conventional eggs you might find at the supermarket.

They were higher in vitamin A, E and omega-3s, as well as lower in cholesterol and saturated fat.

A published study on pastured eggs produced similar results (2).

Another study showed that free-range eggs, which were laid by hens allowed to roam out in the sun, contained three to four times the amount of vitamin D than the eggs of hens that were raised indoors (3).

Summary

Pastured eggs are richer in vitamins A and E, as well as omega-3s. Hens that get to spend time in the sun also lay eggs that contain significantly more vitamin D.

The Bottom Line

At the end of the day, pastured eggs are probably the healthiest type of eggs you can buy. They are more nutritious, and the hens that laid them were allowed free access to the outside and ate a more natural diet.

If you can’t get pastured eggs, omega-3-enriched eggs are your second best choice. If you can’t get either pastured or omega-3 eggs, try to find eggs that are either free-range, cage-free or organic.

Nevertheless, even if that’s not an option, conventional eggs are still among the healthiest and most nutritious foods you can eat.

FAQs

Are pasture-raised eggs better than omega-3? ›

Are pasture-raised eggs better than conventional eggs? ›

Research from Penn State's College of Agricultural Sciences found that compared to eggs from conventionally-raised chickens, eggs from pasture-raised hens had: Double the amount of vitamin E and long-chain omega-3 fats. More than twice the amount of total omega-3 fatty acids.

Is there a difference between omega-3 eggs and regular eggs? ›

Enriching eggs with omega-3 provides another dietary source of this nutrient. Omega-3 eggs contain 0.4 g omega-3 fatty acids compared to 0.04 g omega-3 fatty acids in regular eggs. Omega-3 eggs can also contain up to eight times more vitamin E than regular eggs.

What are the healthiest eggs to eat? ›

Is avocado high in omega-3? ›

Avocados are not a rich source of omega-3 fatty acids. Like other non-animal sources of omega-3 fatty acids, avocados contain the omega-3 fatty acid ALA, which your body does not use as effectively as EPA and DHA. These more beneficial types only come from animal-based sources, such as fatty fish.

Are pasture-raised eggs better than factory farm eggs? ›

In it, researchers found that one pasture-raised egg contains twice as much omega-3 fat, three times more vitamin D, four times more vitamin E and seven times more beta-carotene than eggs from hens raised on traditional feed. From an agricultural standpoint, pasture-raised eggs are often superior too.

What is the best type of egg to buy? ›

Pasture-raised eggs (also known as pastured eggs) are by far the best eggs to buy, but make sure you at least get free range. The grade of eggs refers to the actual quality of an egg's shell, whites, and yolk. From best to worst, the grades are Grade AA, Grade A, and Grade B.

Are brown eggs better than white eggs? ›

The color of the shell does not affect the nutrient content. There is no nutritional difference between a white and a brown egg. The breed of the hen determines the color of her eggs. Chickens such as the Leghorn, White Rock and Cornish, lay white eggs.

Does cooking eggs destroy omega-3? ›

No, research shows both frying and boiling retain 100% of the eggs' omega-3s when cooked properly on medium heat. High heat may damage omega-3s over time.

Does peanut butter have omega-3? ›

Remember, omega-3 fats help reduce inflammation, whereas too many omega-6 fats cause inflammation. Peanut butter is high in omega-6 fats and low on omega-3 fats, so that can cause an imbalanced ratio, especially if its consumed in excess.
