Seral factors influence the extent of pigment in brown egg-laying hens:
- age and strain of the hen
- how producers house the hens
- if the hen has certain diseases such as infectious bronchitis
- hen stress factors such as fear and being frequently disturbed, particularly when laying eggs
Are brown eggs healthier than white eggs?
Nutrient levels are not significantly different in white and brown shell eggs. Some people claim that blue or green eggs from some chickens contain less cholesterol than other eggs.
The size of an egg does affect its nutrition, regardless of its color. Jumbo” eggs contain 90 calories and 8 grams (g) of protein, while medium eggs contain 60 calories and 6 g of protein.
Another factor that can affect the nutrition and health benefits of eggs is what the hens eat. For example, producers may enrich their chickens’ feed with omega-3 fatty acids, vitamins, or other nutrients.
Additionally, eggs from free-range hens allowed to roam outside have a higher vitamin D content due to exposure to sunlight.
Which tastes better?
No evidence suggests that either white or brown eggs taste better overall. One study suggested that brown eggs are heavier than white eggs and have more shell and albumen (egg white). The research also indicates that brown eggs may also have less yolk.
Because of these factors, an individual might decide they have a personal preference for brown or white eggs.
Do brown eggs cost more?
Brown eggs tend to cost more, this is because the hens that lay brown eggs are larger and eat more food.
This extra food cost is reflected in the price producers set for consumers.
Tips for choosing eggs
People should consider freshness and quality when choosing eggs in retail stores.
Consider the following points when buying eggs:
-only purchase eggs that the retailer is refrigerating
-choose eggs with clean, uncracked shells
-don’t buy out-of-date eggs
-look for the grade shield or mark for quality and size
-choose the most useful and economical size for your purposes
-refrigerate as soon as possible after purchase
In the United States, an inspection of eggs for wholesomeness is mandatory. However, grading for quality is voluntary. Companies choose to pay for the USDA to grade their eggs and authorize a grade shield on the carton.
Certified Egg Facts:
Organic: Certified organic eggs are from uncaged hens that are allowed free range of their houses and have access to outdoor space. Additionally, the hens consume an organic diet.
Cage-free: Cage-free eggs carry the shield. Hens must have access to unlimited food and water and have the freedom to roam their area during the laying cycle. The shield does not require cage-free hens to have access to the outdoors. Cage-free hens do not produce more nutritious eggs.
Free-range: Free-range eggs carry the shield. Hens must be in a cage-free environment and have access to the outdoors during their laying cycle.
Antibiotic-free: Producers raised hens without antibiotics of any type.
Vitamin enhanced: Hens’ diets may include components that make the eggs richer in vitamins and other nutrients.
Omega-3 enriched: Hens diets may include flaxseed, algae, or fish oils to increase the omega-3 fatty acids in their eggs.
