Retail jam tarts are ready-made pastry cases with a jam filling. They mainly provide carbohydrate and fat, with smaller amounts of protein and fibre. Per 100g, they contain 58g of carbohydrate, including 32g of sugars, and 14g of fat, including 5.5g of saturated fat. The figures describe shop-bought jam tarts rather than homemade versions.

Carbohydrate and fat provide energy for the body. The sugar and saturated fat content are relevant for people monitoring these nutrients or their overall energy intake. Sugars contribute to tooth decay, particularly when sugary foods are eaten frequently between meals. Full nutrient figures, including energy, salt, vitamins and minerals, are shown in the tables below.
