White Eggs Vs Brown Eggs: Which One Is Better For You?

Chicken eggs come in many different colors. The most common types available at your local grocery store are likely white or brown. Some eggshells even come in blue or blue-green shades (via Healthline). 

While some people may prefer one color egg over another, studies suggest all eggs are nutritionally similar regardless of their color, size, or grade. The color of the egg actually depends on the breed of the chicken. White Leghorn chickens, for example, lay white-shelled eggs, while Rhode Island Reds and Plymouth Rock chickens lay eggs that have brown shells. Araucana, Dongxiang, and Lushi are some of the breeds that lay blue or blue-greed eggs. It's the pigment the hen produces that determines the color of the egg. 

While genetics is the main factor that determines eggshell color, other factors can influence shade, as well. For example, the hen's diet, environment, and stress level may affect egg color to some extent. However, these would only influence the shade (making the eggs lighter or darker) and wouldn't affect the color itself.

While the health effects of eggs have been a source of debate in recent years, both brown and white eggs are considered healthy foods in moderation. In fact, the American Heart Association (AHA) suggests one egg (or two egg whites) per day as part of a healthy diet. 

Although the color of the eggshell does not determine how healthy an egg is, nutritional content can be affected by a few other factors. A hen allowed to roam in the sunshine, for example, will produce eggs containing more vitamin D. And hens eating feed rich in omega-3 fatty acids will in turn, lay eggs higher in omega-3 fatty acids. 

The color of eggs also does not affect the taste. However, other factors, such as the hen's diet, will. Hens that are fed a fat-rich diet will produce more flavorful eggs, while hens fed too much fish oil may yield fishy-tasting or "off" eggs. Eggs that are stored for longer periods of time might also lose their flavor. For optimal freshness, store eggs at a stable, low temperature in the refrigerator.
