Digestive biscuits were first produced in England and are now a popular product in the US and many other countries. People used to think that they aided digestion because they contain sodium bicarbonate. Sodium bicarbonate is used in the digestive system to increase the alkaline content in the small intestine. This acts as a counter measure to the acid created by the pancreas and creates a Ph neutral environment.
Traditionally, digestive biscuits contain brown wheat flower, which is the main contribution to its semi-sweet flavor. So how many calories are there in a digestive biscuit? It is generally accepted that the average biscuit contains 65-75 kcal. However, with the broad range of available types of biscuits, this can vary quite a lot. For instance, some manufacturers, such as McVities, coat the upper layer of their biscuits with chocolate which increases the amount of calories contained significantly.
McVities is one of the oldest manufacturers of digestive biscuits, and over seventy million of their chocolate covered cookies are eaten every year in the UK alone. So how many calories are there in a McVities? According to the nutritional information on the package, one biscuit contains 92 calories. This means that per 100 grams, McVities supply 489 kcal. One biscuit will also provide 4.5 grams of fat (2.2g saturated fat) and 11.7g of carbohydrates. As you may have guessed, the protein content is low at 1.3g per biscuit. The sodium content is surprisingly low at 100mg per biscuit. So if you enjoy digestive biscuits, it is advisable to purchase them without the chocolate coating, as this renders the biscuit a much less healthy snack.
