Top eight digestive biscuits

HEALTHY or not? The wholemeal digestive biscuit suggests some kind of health benefit — an aid to digestion, perhaps, with plenty of decent fibre.

Described and stamped on each one as a sweetmeal biscuit, it was created in 1839 by two Scottish doctors.

The idea was that the sodium bicarbonate would neutralise acids and help with digestion. If that were the case, some breads and cakes should also have the same effect.
