Polenta, hydrated, raw

Polenta is a cereal food made from ground maize. The figures here describe a corn-based product in its hydrated, raw form, rather than dry polenta. It mainly provides carbohydrate, with 15g per 100g, alongside 1.7g of fibre and 1.9g of protein. Its salt content is 1.4g per 100g.

Carbohydrate provides energy for the body, while fibre helps support normal bowel function. Although this polenta contains little fat and only trace amounts of sugar, its salt content is worth noting for people monitoring their salt intake. Salt from ingredients added during preparation also contributes to the total in a meal. Full nutrient figures are provided in the tables below.
