     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.  

Cagefree?  Organic?  Brown? White? Omega3s? 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 Omega3s? Omega3 eggs come from a hen whose diet has added flaxseed(亚麻籽) ,which

produces an egg containing an average of 225 mg of Omega3 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 Omega3s. Let eggs be eggs.

     ●Does your egg need exercise? Freerange 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.
