Eggs are one of the healthiest foods you can include in your diet. They are rich in protein and loaded with important vitamins and minerals like vitamin A, B12, and selenium. Besides being nutritious, eggs are also super versatile and simple to cook, which is why they are a common part of many people’s meals. However, buying eggs can be tricky because of all the different labels on the cartons. It’s essential to know what these labels indicate, as they provide details about the treatment of the hens and the nutritional value of the eggs inside.
The Healthiest Eggs: Pasture-Raised, Organic, Free-Range, or Conventional?
Conventional
Conventional eggs are produced by chickens that are kept in cramped indoor cages, about the size of a piece of paper (67 square inches). These chickens don’t get to interact with each other, stretch their wings, or even walk around, which results in a poorer quality of life and eggs that aren’t as nutritious. Their diet usually consists of grains that are filled with GMOs, harmful pesticides, and antibiotics.
Cage-Free
Honestly, there isn’t much of a difference between regular eggs and cage-free eggs. The chickens that produce cage-free eggs still have their beaks and wings trimmed, and they live in cramped spaces with limited sunlight and no sure access to the outside. The main distinction is that, as the name implies, these chickens aren’t kept in cages.
Free-Range
When you hear the term free-range, do you picture chickens wandering around in green fields all day? If that’s the case, you might want to reconsider. While this label does mean that chickens get some outdoor time, it’s usually just a small part of their lives. Sadly, free-range is a vague term. The time they spend outside and the space they have can differ a lot. You might also come across labels saying antibiotic-free, but remember that very few hens are actually given antibiotics.
Pasture Raised
When discussing egg labels, pasture-raised is considered the best option. These eggs are sourced from chickens that are raised on pasture, meaning they have the freedom to roam outside and enjoy plenty of sunlight. The chickens are fed an organic diet, which includes natural foods like bugs and worms for their nutrition. Additionally, pasture-raised eggs do not contain any hormones or antibiotics.
A study conducted in 2007 revealed that eggs from pasture-raised hens are significantly more nutritious than those from conventional chickens. These pasture-raised eggs have about 67% more vitamin A, double the omega-3 fatty acids, three times the vitamin E, seven times the beta-carotene, and four to six times the vitamin D compared to regular store-bought eggs, even if they are labeled as organic or free-range.
What Are the Hens Fed?
1. Eggs from Hens Fed a Vegetarian Diet
This topic can be quite confusing. Many people assume that vegetarian diets are healthier, but it’s important to remember that chickens are naturally omnivores, meaning they eat both plants and animals. So, just because hens are fed a vegetarian diet doesn’t necessarily make their eggs healthier.
2. Omega-3 Enriched Eggs
These eggs are packed with omega-3 fatty acids, specifically around 400mg of EPA and DHA. This boost comes from the hens being fed a diet that includes extra omega-3s. However, it’s worth noting that the living conditions for these hens are similar to those of conventional or caged hens.
3. Organic Eggs
Hens that lay organic eggs are often kept in conditions similar to conventional hens, but they might have a bit more space to move around. The key point is that these hens are not given antibiotics, and their feed is organic, meaning it doesn’t have any pesticides or fertilizers.
4. Eggs Without Added Hormones
In the US, Europe, and many other regions, no chickens are given extra hormones, so all eggs can be considered hormone-free.
Brown eggs are not healthier than white eggs.
White eggs can be just as nutritious as brown eggs, and vice versa, depending on what the hens eat and how they are raised. The only thing that affects the color of the egg is the type of chicken that laid it.
The Verdict
When it comes to choosing the healthiest eggs, organic, pasture-raised eggs are the top pick. Free-range eggs come in a close second.
