Think the color of your eggs affects their health benefits? Think again—this myth has been cracking under scientific scrutiny for years. You might have strong preferences for brown or white eggs, perhaps believing one is superior to the other. But here’s the truth you’ve been missing: shell color has zero impact on nutrition. Let’s settle the debate once and for all, with insights from top dietitians.
Meet the Experts:
- Vicki Koenig, M.S., R.D., C.D.N., a seasoned registered dietitian at Nutrition-Wise, breaks down the science behind eggshell colors.
- Emer Delaney, R.D., P.T., founder of My Private Dietitian, explains why pricing differences exist—and why they don’t reflect nutritional value.
Brown Eggs vs. White Eggs: What’s the Real Difference?
Contrary to popular belief, the color of an eggshell isn’t a health indicator—it’s a genetic trait of the hen. "It’s all about the breed of the chicken," explains Koenig. "White-feathered hens lay white eggs, while red or brown-feathered hens produce brown eggs." Simple, right? But here’s where it gets controversial: many shoppers assume brown eggs are ‘healthier’ or ‘more natural’ simply because they look rustic. Spoiler: they’re not.
Why Are Brown Eggs More Expensive?
Delaney reveals the surprising reason: "Brown-egg-laying hens are typically larger breeds that require more feed and resources, driving up production costs." For example, Rhode Island Reds (a common brown-egg layer) weigh over 7 pounds, while Leghorns (white-egg layers) are smaller and more efficient. So, you’re paying for the hen’s upkeep—not a nutritional upgrade.
Nutrition Showdown: Is One Color Better?
"Nutritionally, brown and white eggs are identical," Koenig states firmly. Both pack 6 grams of high-quality protein, vitamins A, D, E, K, brain-boosting choline, and inflammation-fighting antioxidants. Even the American Egg Board confirms: farming methods (organic, free-range, etc.) don’t alter core nutrients unless hens are fed fortified diets (like omega-3-enriched feed).
But Wait—There’s a Catch
A 2022 study in Molecules found organic eggs had higher levels of nutrients crucial for child development, while conventional eggs excelled in compounds aiding fat metabolism. Does this mean organic is ‘better’? Not necessarily—both types offered robust nutrition. This subtle nuance sparks debate: Should we prioritize farming practices over shell color?

The Bottom Line
Shell color = hen’s breed. That’s it. "It’s as fun—and as meaningless—as that," laughs Delaney. While brown eggs might look fancier on your brunch table, they’re nutritionally equal to white eggs. So, save your cash or splurge based on preferences—just don’t fall for marketing myths.
