　　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？Help！Here are some tips to help you figure out which eggs you should choose：

　　●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 dose of Omega-3s.Let eggs be eggs.

　　●Does your egg need exercise？Free-range eggs are from hens raised without the confines of a cage，though they may or may not have spent much time outdoors.Organic eggs are from hens whose feed must meet organic standards.These hens must be raised humanely，and they must be given time to stay 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 shape and they may or may not be certified (证明) organic；however，they have one quality I prize：I know exactly where my food came from and how it came to be！In some cases I can even ask the farmer when the eggs were laid and what the hens were fed.
