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.
The eggs had similar levels of fat and cholesterol, but the pastured eggs had three times more omega-3s, three times more vitamin D, 220 percent more vitamin E and 62 percent more vitamin A than eggs from caged hens.
There are several different types of eggs, and their nutritional contents vary and 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 can roam free, eating plants and insects (their natural food) along with some commercial feed. 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.
