Friday's Last Spoonful: Just a matter of egg coloring

Brown vs. white

Wonder what the big deal is about brown eggs and why they’re usually more expensive than white ones? Brown eggs come from certain breeds, such as Wyandotte or Rhode Island Red chickens. These chickens require more feed per pound since they’re also larger in size compared to the breeds that produce white eggs. Farmers spend more money raising these chickens. Merchants pass along the slight cost hike to consumers. As for content? Comparisons have shown no real difference in nutrition or value. Scientists have identified protoporphyrin as the added chemical agent that causes the brown- colored shells. White eggs lack protoporphyrin.
