Eggs fit into a healthy, well-balanced diet. One large egg equals 70 calories, 4.5 grams fat (only 1.5g is saturated fat), and 213 milligrams of cholesterol. Egg whites are fat-free and cholesterol free. An egg is one of nature's most nutritious creations. Eggs are protein-rich, low in sodium, and contain a variety of vitamins and minerals. Eggs are inexpensive, delicious, and easy to cook.

Exquisitely simple, yet enormously complex, the egg is one of nature's marvels. Check out the incredible nutritional value of one simple egg.

THE YOLK: A Nutrient Goldmine!!

There's more to eggs than just the whites!  Many individuals aren't aware of the nutrient package the whole egg provides, a majority of which are found in the yolk and play key roles in many aspects of health at all ages, from supporting fetal development in pregnant women to helping protect brain health in older adults.

Egg Composition

A. Shell

  • Outer covering of egg, composed of calcium carbonate
  • May be white or brown depending on breed of chicken
  • Color does not affect quality, cooking characteristics, or nutritional value

B. Air Cell

  • Pocket of air formed at the large end of the egg
  • Caused by contraction of contents
  • Increases in size with age

C. Yolk

  • Yellow portion of egg
  • Color varies with feed of the hen, but doesn't indicate nutritional content. Brown eggs usually have darker colored yolks

D. Vitelline (yolk) Membrane

  • Clean seal which holds egg yolk

E. Shell Membranes

  • Two membranes - inner and outer shell membranes - surround the albumen
  • Provide protective barrier against bacterial penetration
  • Air cell forms between these two membranes

F. Thin Albumen

  • Nearest to the shell
  • Spreads around thick white of high-quality egg

G. Chalaza

  • Twisted, cordlike strands of egg white
  • Anchors yolk in center of egg
  • Prominent chalaza indicates high quality

H. Thick Albumen (white)

  • Excellent source of riboflavin and protein
  • Stands higher and spreads less than thin white in high-quality eggs
  • Thins and becomes indistinguishable from thin white in low-quality eggs
Egg Size & Quality

Eggs are graded for both quality and size; however, quality and size are not related.  Eggs should be selected on the basis of both. Large eggs may be of high or low quality, and high-quality eggs may be of any size.

How long will an egg keep?

Fresh shell eggs can be kept refrigerated in their carton for at least 4-5 weeks beyond the pack date. Quality losses should be insignificant if the eggs are refrigerated as soon as possible after purchase from a refrigerated case.

Hard-cooked eggs should be kept in the refrigerator for up to one week.
