Water biscuits are plain, baked crackers made from cereal flour. The figures here cover three brands and describe the biscuits as sold. They mainly provide carbohydrate, with some fat and protein. Per 100g, they contain 76g of carbohydrate, 13g of fat and 11g of protein, with an energy content of 1859 kJ.

Carbohydrate provides energy for the body, while protein supports the maintenance and repair of body tissues. Water biscuits also contain salt, which is worth noting for people monitoring their salt intake. The amount eaten and any toppings or accompaniments affect the overall energy and salt content.

About these figures

Values are per 100g of the food as described (3 brands). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.

These figures come from an older part of the dataset that is no longer updated. Original source: MW3, 1960.
