A digestive biscuit, sometimes described as a sweet-meal biscuit.
It is a semi-sweet biscuit that originated in the United Kingdom and is popular worldwide.
The digestive was first developed in 1839 by two Scottish doctors to aid digestion.
The term “digestive” is derived from the belief that they had antacid properties due to the use of sodium bicarbonate when they were first developed.
Historically, some producers used diastatic malt extract to “digest” some of the starch that existed in flour prior to baking. (source)
Can guinea pigs eat digestive biscuits?
They can have a nibble of them, but they are generally not the type of food that guinea pigs should eat regularly.
But there is no harm in them nibbling one if presented with it.
