Meet Real Free-Range Eggs

Posted by in Blog | 0 comments

Most of the eggs currently sold in supermarkets are nutritionally inferior to  eggs produced by hens raised on pasture. That’s the conclusion we have reached  following completion of the 2007 Mother Earth News egg testing project. Our  testing has found that, compared to official U.S. Department of Agriculture  (USDA) nutrient data for commercial eggs, eggs from hens raised on pasture may  contain:

• 1/3 less cholesterol • 1/4 less  saturated fat • 2/3 more vitamin  A • 2 times more omega-3 fatty  acids • 3 times more vitamin E • 7  times more beta carotene

These amazing  results come from 14 flocks around the country that range freely on  pasture or are housed in moveable pens that are rotated frequently to maximize  access to fresh pasture and protect the birds from predators. We had six eggs  from each of the 14 pastured flocks tested by an accredited laboratory in  Portland, Ore. The chart at the end of this article shows the  average nutrient content of the samples, compared with the official egg nutrient  data from the USDA for “conventional” (i.e. from confined hens) eggs. The  chart lists the individual results from each flock.

The 2007 results are similar to those from 2005, when we tested eggs from  four flocks all managed as truly free range. But our tests are not the first to  show that pastured eggs are more nutritious — see “Mounting Evidence” below  for a summary of six studies that all indicated that pastured eggs are richer in  nutrients than typical supermarket eggs.

We think these dramatically differing nutrient levels are most likely the  result of the different diets of birds that produce these two types of eggs.  True free-range birds eat a chicken’s natural diet — all kinds of seeds, green  plants, insects and worms, usually along with grain or laying mash. Factory farm  birds never even see the outdoors, let alone get to forage for their natural  diet. Instead they are fed the cheapest possible mixture of corn, soy and/or  cottonseed meals, with all kinds of additives — see “The Caged Hen’s Diet”  below.

The conventional egg industry wants very much to deny that  free-range/pastured eggs are better than eggs from birds kept in crowded,  inhumane indoor conditions. A statement on the American Egg Board’s Web  site says “True free-range eggs are those produced by hens raised  outdoors or that have daily access to the outdoors.”

Baloney. They’re trying to duck the issue by incorrectly defining “true  free-range.” And the USDA isn’t helping consumers learn the truth, either:  “Allowed access to the outside” is how the USDA defines “free-range.” This  inadequate definition means that producers can, and do, label their eggs as  “free-range” even if all they do is leave little doors open on their giant  sheds, regardless of whether the birds ever learn to go outside, and regardless  of whether there is good pasture or just bare dirt or concrete outside those  doors!
