Eggs from pasture raised chickens wins for the best choice. Yes, chickens were created to eat bugs and greens off the land which is partly why roaming free on a pasture makes their eggs higher in key nutrients. Here are two nutrients highlighted: Omega-3 fatty acids are formed in the chloroplast of green leafs so chickens feeding off of the plants in the fields increase the content of that under consumed fatty acid and pass it onto their eggs. Pastured chicken eggs also have ” 3-6 times more Vitamin D then hens raised in confinement.”1 Well that’s because they walk around in the sunshine all day.
One study1 found that when compared to commercial eggs, pastured eggs had:
- 1/3 less cholesterol
- 1/4 less saturated fats
- 2/3 more vitamin A
- 2 times more Omga-3 fatty acids
- 7 times more beta carotene
Here is more on Omega-3 fatty acids: “Omega-3s are called “good fats” because they play a vital role in every cell and system in your body. For example, of all the fats, they are the most heart-friendly. People who have ample amounts of omega-3s in their diet are less likely to have high blood pressure or an irregular heartbeat. Remarkably, they are 50 percent less likely to suffer a heart attack. Omega-3s are essential for your brain as well. People with a diet rich in omega-3s are less likely to suffer from depression, schizophrenia, attention deficit disorder (hyperactivity), or Alzheimer’s disease.”1
I also found this another article that breaks down all the definitions in relation to types of eggs you can buy: pastured raised, cage free, free range, organic, and conventional (click here for article).
One must be aware of “all vegetarian diet”. That does not mean hens were allowed free range on a pasture.
