Mother Earth News recently finished their latest egg-testing project, confirming their 2005 test results that showed true free-range eggs are far more nutritious than commercially raised eggs.
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 dramatically differing nutrient levels are most likely the result of the differences in diet between free-range pastured hens, vs. commercially farmed hens.
Without citing any research of their own, most egg industry advocates hold fast to their claim that commercially farmed eggs are no different from pastured eggs, and that hens’ diets do not alter their eggs nutritional value in any significant way.
Mother Earth News points out the flawed and downright fraudulent definitions of “true free-range.” The United States Department of Agriculture (USDA) defines “free-range” as chickens that have “access to the outside.” However, it does not define their diets, nor whether or not the “outside access” is to a cement courtyard or a field fit for foraging.
