what are digestive biscuits
From Wikipedia, the free encyclopedia. A digestive biscuit, sometimes described as a sweet-meal biscuit, is a semi-sweet biscuit (usually known in American English as a cookie) 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.
