Rye crispbread is a dry, baked cereal product made from rye. The figures here describe plain rye crispbread, based on samples of original and dark varieties. It mainly provides carbohydrate and fibre, with some protein and little fat. Per 100g, it contains 63g carbohydrate, 20g fibre, 8.6g protein and 1.4g fat.

Carbohydrate provides energy, while fibre helps support normal bowel function. Protein is needed for the growth and repair of body tissues. Rye contains gluten, so rye crispbread is not suitable for people with coeliac disease. Salt is also present and is worth noting when monitoring salt intake.
