Nutrition Comparison
Brown Eggs vs White Eggs
One of the most common egg questions answered: there is no nutritional difference between brown and white eggs. The color comes from the hen's breed, not the egg's nutrition.
The Short Answer
Brown and white eggs are nutritionally identical.
Shell color is determined by hen breed, not nutrition. The USDA does not distinguish between brown and white eggs in its nutrient database because they share the same nutritional profile.

What Actually Affects Egg Nutrition
While shell color doesn't matter, these factors do affect egg nutrition:
- Hen diet: Hens fed omega-3 enriched diets (containing flaxseed) produce eggs with 2-3x more omega-3 fatty acids. Hens fed carotenoid-rich diets produce eggs with darker, more nutrient-dense yolks.
- Pasture-raised vs caged: Studies show pasture-raised eggs can have up to 2x more vitamin E, 2-3x more omega-3s, and significantly more vitamin D due to sun exposure.
- Organic vs conventional: Research shows modest differences in some micronutrients, but not in macronutrients (protein, fat, calories).
- Egg size: This is the biggest variable — a jumbo egg (63g) has 25% more nutrition than a large egg (50g).
Why Brown Eggs Cost More
Brown eggs are typically 10-25% more expensive than white eggs. This is due to:
- Larger hens: Brown-egg breeds (Rhode Island Reds, Plymouth Rocks) are physically larger than white-egg breeds (White Leghorns) and consume more feed per egg produced.
- Lower production: Brown-egg breeds tend to lay slightly fewer eggs per year.
- Marketing perception: Consumer perception that brown = natural/healthy allows producers to charge a premium.
The price difference reflects production economics, not nutritional superiority.
Frequently Asked Questions
Are brown eggs healthier than white eggs?
No. According to USDA data, brown and white eggs have identical nutritional profiles. The shell color is determined by the breed of hen, not the nutritional content. Both contain the same calories (72 per large egg), protein (6.3g), fat (4.8g), and micronutrients.
Why are brown eggs more expensive?
Brown eggs typically cost more because the hen breeds that lay them (like Rhode Island Reds) are larger and eat more feed. The higher price reflects production costs, not superior nutrition. Marketing has also created a perception that brown eggs are "more natural."
Do brown and white eggs taste different?
When from hens raised in similar conditions and fed the same diet, brown and white eggs taste identical. Any taste differences are due to the hen's diet and living conditions, not shell color. Free-range eggs may taste different from caged eggs regardless of color.
What determines egg shell color?
Shell color is determined by the breed of the hen. White-feathered breeds (like White Leghorns) lay white eggs. Brown-feathered breeds (like Rhode Island Reds, Plymouth Rocks) lay brown eggs. Some breeds lay blue or green eggs (Ameraucanas, Araucanas).
