Why brown food isn’t always best
This past week has shown that, when discussing the colour of eggshells, we need to walk on them. Sainsbury’s has announced that it is phasing out brown eggs in favour of white because the latter have a 12.7 per cent lower carbon footprint. As suspiciously precise as that figure is, it caused some commentators to rant that net zero madness is just a cover for cost-cutting. White hens lay white eggs and eat less feed, which in turn reduces emissions, so what's everyone getting scrambled up over? However, buried in the original press release is a throwaway admission that Britain only switched to brown eggs in the 1970s because they were ‘perceived as more natural’. Even Queen Elizabeth ‘favour[ed] brown eggs, believing that they taste better’.
