Egg White vs. Egg Yolk Color: What You Need to Know

Do white or Brown Eggs Offer Better Nutrition? A Scientific look

Shoppers frequently debate whether to choose white eggs or brown eggs, seeking the best option for taste, cooking, and price. Despite common beliefs, scientific data reveals the color of the shell isn’t the primary indicator of quality. The key factor lies in the hen.

Eggshell Color and Genetics

The color of an eggshell is primarily determined by the genetics of the hen. Hens with white plumage and clear earlobes lay white eggs, while hens with reddish-brown plumage and red earlobes lay brown eggs. This visual characteristic provides no information about freshness, quality, or food safety; it is simply a hereditary trait.

According to a 2023 report by the United States Department of Agriculture (USDA), in December 2023, approximately 78% of eggs sold in the United States were white, while 22% were brown. This distribution reflects both consumer preference and the prevalence of white-feathered hens in commercial egg production.

The USDA also notes that eggshell color dose not affect nutritional value. A 2022 study published in the Journal of Agricultural and Food Chemistry compared the nutritional composition of white and brown eggs from various hen breeds. The study found no statistically notable differences in protein content, vitamin levels, or cholesterol levels between the two types of eggs.

Flavor differences, frequently enough attributed to shell color, are also minimal. A blind taste test conducted by Good Housekeeping Institute in november 2023, involving 50 participants, revealed that 68% of participants could not distinguish between the taste of white and brown eggs.

Price variations between white and brown eggs are typically linked to production costs. Brown eggs generally cost more-an average of $0.30 to $0.50 more per dozen as of January 14, 2026, according to data from Statista-because brown-feathered hens require more feed and tend to be smaller, resulting in lower egg production rates.

Regarding environmental impact, a 2021 life cycle assessment by the Poultry Science Association indicated that the production of both white and brown eggs has a comparable carbon footprint, with feed production being the most significant contributor to greenhouse gas emissions in both cases.
