Sainsbury's has become the first supermarket in the UK to announce it will sell white eggs again, marking a significant shift in the nation's egg-buying habits. The move is part of a broader effort by retailers to reduce carbon emissions, as white eggs have a lower environmental footprint than their brown counterparts.
Why White Eggs Are Making a Comeback
White eggs were once the norm in the UK, but brown eggs gained popularity in the 1970s when many shoppers believed they were healthier and more natural. Those claims have since been debunked, yet brown eggs remained the preferred choice. Now, supermarkets are revisiting white eggs as a sustainable alternative.
Key Differences Between White and Brown Eggs
- Appearance: The shell colour is the only visual difference. White eggs come from white hens, while brown eggs come from brown hens.
- Taste and Nutrition: Despite common misconceptions, there is no difference in taste, nutrition, or cooking quality. The egg inside is identical regardless of shell colour.
- Size: Brown eggs are often slightly larger because the hens that lay them tend to be bigger.
- Environmental Impact: Hens that lay white eggs are generally smaller and eat less feed, resulting in a lower carbon footprint.
Welfare Benefits
The return of white eggs is not just about sustainability. Some experts suggest that breeds laying white eggs are less prone to feather pecking and other welfare issues, potentially improving conditions for the hens themselves.
As more UK supermarkets consider following Sainsbury's lead, shoppers may soon see white eggs become a common sight on shelves once again.
