Consumers often associate color differences with quality, taste, and nutritional value, but the factors that truly influence choice are related to the origin, preservation, and conditions of the product.
Understanding these characteristics helps compare prices and avoids decisions based solely on appearance.
In the comparison between white and brown eggs, the shell color does not determine if the food is more nutritious, tasty, or healthy, as both types have similar composition when they come from birds fed and raised under equivalent conditions.
Even though the brown shell is often associated with a more natural or superior product, this perception has no proven nutritional advantage, according to information from the United States Department of Agriculture on grading, composition, and commercial characteristics of eggs.
When choosing a package, therefore, the consumer can consider price, size, preservation, and information provided by the manufacturer, without paying more for the brown egg just because they believe the external pigment ensures better quality or offers additional health benefits.

Shell color depends on the chicken’s genetics
During egg formation, pigments are deposited on the shell according to the bird’s genetic characteristics, causing certain breeds to produce white eggs, while others lay brown, bluish, or greenish eggs, without significant alteration in the internal content.
Although it is common to associate light-colored chickens with white eggs and reddish birds with dark shells, the appearance of the feathers does not function as an absolute rule, because the chicken’s breed is the factor that determines the external tone of the product.
For this reason, egg white, yolk, proteins, vitamins, and minerals do not become better due to the pigment present in the shell, and products of similar size, coming from comparable systems, do not offer nutritional advantage just because they have a different color.
In the standards adopted by the United States Department of Agriculture, quality evaluation considers the condition of the shell and the internal conditions of the white and yolk, while color serves only to commercially separate white and brown eggs.
Why brown eggs may cost more
In many markets, brown eggs appear at a higher price, but the higher price does not prove a greater amount of proteins, vitamins, or minerals, as the difference is usually related to production costs and the characteristics of the breeds responsible for laying.
This additional cost may occur because some hens that produce brown eggs are larger, consume more feed, and generate higher expenses for the producer, factors that end up reflected in the price charged per dozen or tray at retail.
Furthermore, part of the difference observed on the shelf may involve size, type of packaging, commercial positioning, and production method, elements that need to be analyzed separately, as none of them represent nutritional superiority determined exclusively by the shell color.
Expressions like “cage-free” or “free-range” describe the housing conditions of the birds, while white and brown only identify the external appearance, without indicating, by themselves, the system used in raising the hens.
According to the United States Department of Agriculture, there is no definitive scientific data demonstrating a nutritional difference caused exclusively by caged housing, cage-free raising, or the birds’ access to the external environment.
How to choose eggs at the supermarket
Before placing the package in the cart, the integrity of the product deserves more attention than the shell color, mainly because cracks, excessive dirt, or improper storage can compromise the safety and preservation of the eggs.
Among the recommended precautions is the purchase of units kept refrigerated, with clean and intact shells, reducing the possibility of taking home damaged products or those exposed to inadequate conditions during transport and storage in the establishment.
After purchase, refrigeration should be maintained, as temperature and preservation are directly related to food safety, unlike color, which does not provide a reliable indication of freshness, contamination, or internal conditions of the white and yolk.
Attention should also be given to the packaging, which can inform expiration, preferred consumption, size, and category, allowing for comparison of batches and preventing different products from being evaluated solely by the total price charged for each box, carton, or tray available.
Over time, the membrane surrounding the yolk loses resistance and the white tends to become more watery, which is why the printed dates serve as a reference for the product’s best quality period.
Even so, these indications do not replace the verification of storage conditions, the integrity of the units, and the guidelines provided by the manufacturer, aspects more relevant for the choice than any difference between white or brown shells.
White or Brown Eggs: Which Option to Buy
When two packages present eggs of equivalent size, intact shells, and proper storage, the choice between white and brown can be made based on price or personal preference, without the expectation of receiving a nutritionally superior food due to the color.
Real differences may exist between brands, batches, sizes, production systems, and storage conditions, but none of these should be automatically attributed to the external pigment, as eggs of the same color can also have different origins and quality standards.
Instead of turning a genetic characteristic of the hen into a sign of health benefit, the consumer can compare price per unit, size, expiration date, shell condition, and refrigeration, factors that offer more useful references for evaluating the product.
In the next purchase, will the shell color continue to be the main criterion for choice, or will information such as storage, expiration date, size, integrity, and price per unit weigh more in the decision among the options available at the supermarket?
