Mite bite: While we don't mind a Marmite sandwich every now and then, we were pretty horrified to read - in the Sun, admittedly - last week of the East London builder who has been living on little else for the last quarter of a century.

George Lambert (35) from Hackney apparently eats the savoury spread at every meal and each month he makes his way through a stack of sandwiches seven feet high.

He's not entirely averse to variety in his diet, however, occasionally adding beetroot, bananas, celery and sardines to his Marmite treats.
