As a kid, I can remember going to the supermarket and grabbing eggs off the shelf. I would run them home to my mother because they were usually going into a delicious cake. Times have changed. Cage-free? Organic? Brown? White? Omega-3s(一种脂肪酸)?Help! Here are some tips to help you figure out which eggs you should be eating.

Brown or white? In fact, color is simply a sign of the breed of hen. Find the freshest egg with the most flavor and let color be a secondary concern.

Extra Omega-3s? Omega-3 eggs come from a hen whose diet has added flaxseed (亚麻籽)，which produces an egg containing an average of 225 mg of Omega-3 fatty acids and vitamin E. The countless health benefits for humans make these eggs an attractive purchase. My opinion? Eat a piece of fresh fish and get a pure pill of Omega-3s. Let eggs be eggs.

Does your egg need exercise? Free-range eggs are from hens raised without the limit of a cage, though they may or may not have spent much time outdoors. Organic eggs are from hens whose food must meet organic standards. These hens must be raised humanly, and they must be given time to the outdoors. Hey, happier hens do lay tastier eggs.

Does local make a difference? Nothing is better than local eggs. They may have a feather or two stuck to them or be a little imperfect in shape and may or may not be certified organic; however, they have one quality. I know exactly where my food came from and how it came into being! In some cases I can even ask the farmer when the eggs were laid and what they were fed.
