Buying brown or white eggs is the dilemma that many of us face when we are in front of supermarket shelves, writes metrotoday.it.
The debate between brown and white eggs is repeated every time you shop: many people are convinced that brown eggs are healthier, more nutritious, or more "natural" than white eggs.
The reality, according to nutritionists and food scientists, is simpler and has less to do with shell color than with truly important factors such as the chicken's diet, breeding conditions, and the freshness of the product.
Shell color: genetics, not nutrition
The first thing to understand is that shell color is not an indicator of nutritional quality or superior health value. The pigment that determines an egg's color is produced by the hen as the egg passes through her reproductive tract: brown eggs acquire pigments called protoporphyrins, while white eggs come from genetic lines that do not deposit these pigments.
In practice: The color of the eggshell is determined by the breed of chicken. Chickens with white feathers and light-colored earlobes tend to lay white eggs, while chickens with red or brown feathers lay brown eggs.
There is no direct relationship between eggshell color and nutrient content.
Comparative studies have shown that white and brown eggs have very similar nutritional profiles, with the slight differences attributed more to the hen's diet than to shell color.
Factors such as the hen's diet, their breeding environment, and specialized diets (e.g., rich in omega-3) have a much greater impact on egg quality.
Egg Nutrition: What Really Matters
Many consumers believe that brown eggs contain more protein or vitamins, but nutritional data for standard eggs shows that:
Both have about 6-7 grams of protein per egg and less than 80 calories.
They contain vitamins A, D, E and K, minerals such as iron and selenium, and choline, which is important for memory and brain function.
According to reputable nutrition sources, there is no substantial evidence that different schools of thought claim that one egg color is inherently healthier than another; eggs are considered a source of high-quality and nutritious protein in both cases.
So why do brown eggs cost more?
Another frequently asked question has to do with price: why do brown eggs often cost more than white ones?
The basic explanation is economic and related to breeding: Chickens that lay brown eggs tend to be larger and stronger breeds, with higher feeding and handling costs.
Historically, these higher costs have been reflected in the price. Even though production costs have stabilized, the perceived “superior” value of brown eggs keeps their price higher on the shelf.
