A Major British Supermarket Is Ditching Brown Eggs for White Ones — Here’s Why

Sainsbury’s is changing one of the most familiar sights in British shopping baskets: the brown egg. The supermarket is switching its own-brand egg range from brown shells to white shells as part of a wider push to cut emissions across its supply chain.

The move is not about taste, quality, or nutrition. Sainsbury’s says white and brown eggs are the same nutritionally, but white-egg-laying hens can bring environmental and welfare advantages that make the switch important for its net zero plans.
