LATEST RESULTS: New test results show that pastured egg producers are kicking the commercial industry's derriere when it comes to vitamin D! Eggs from hens raised on pasture show 4 to 6 times as much vitamin D as typical supermarket eggs. Learn more: Eggciting News!!!
RESULTS FROM OUR PREVIOUS STUDY: Eggs from hens allowed to peck on pasture are a heck of a lot better than those from chickens raised in cages! Most of the eggs currently sold in supermarkets are nutritionally inferior to eggs produced by hens raised on pasture. Thats 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 in Meet the Real Free-range Eggs (October/November 2007) 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.
Exactly what I was going to mention... farm fresh anything is better than store bought anything... anyday... anytime.
