Why some eggs are white (and why that’s great for your breakfast)
Short answer: shell colour comes from the hen’s genetics — not the hen’s health or the egg’s nutrition. White-shelled eggs are simply laid by breeds that don’t add brown pigments to the shell. The inside’s the same classic, protein-rich egg you love. Don’t just take our word for it; the USDA and Academy of Nutrition & Dietetics both say nutrition doesn’t depend on shell colour.
So, what paints the shell?
All eggs start out with a white shell. Near the end of the egg’s journey through the shell gland, some breeds deposit natural pigments. Brown hues come from protoporphyrin IX, while blue-green shells (from breeds like Araucanas) come from biliverdin. If a breed doesn’t deposit pigment, the shell stays white — perfectly normal, perfectly delicious.
White vs brown: any real difference?
- Nutrition: No meaningful difference. See the USDA and MSU Extension.
- Taste & yolk colour: Driven more by the hen’s diet and freshness than shell colour. (Pasture and certain feeds can deepen yolk colour.)
- Price: Brown eggs sometimes cost more for marketing or production reasons, not because they’re healthier. See Consumer Reports and USDA grading Q&A.
But don’t people “prefer” brown eggs?
Preferences are mostly cultural and visual. Studies and reviews show shell colour affects perception, not nutrition. See this scholarly overview of cultural preferences and a poultry-science review of eggshell colour. In short: choose what you find beautiful.
Royal(ish) humour
There’s a cheeky myth that Queen Elizabeth II had very specific egg opinions. Some reports say her chefs made luxurious scrambled eggs; others note she often kept breakfasts simple. Whether her eggs were white or brown, we’ll leave to palace lore. Either way, here’s to a long, egg-fuelled life — crown optional.
Ready to crack on?
If you’re after that crisp, clean presentation (and the same great nutrition), white eggs are a brilliant pick. They’re kitchen workhorses that also look gorgeous in bakes and brunch photos.
P.S. Shell colour doesn’t change shell strength in a meaningful way either; that’s more about hen age and nutrition. Curious? Start with the science review.
