Our daily bread

Sir, – Further to John McKenna's "The best thing since sliced bread? Ban the sliced pan" (Health + Family, October 21st), just because white bread is bad for swans, I do not see why the same is true for humans.

I have been eating it for over 60 years and have come to no harm as a result, but, like the swans, I would draw the line at mouldy bread. – Yours, etc,

ANNA GRAHAM,

Balbriggan,
