Mars bar and own brand equivalents

Mars bars and own-brand equivalents are chocolate-coated confectionery bars with nougat and caramel centres, described here as sold in standard, snack and fun sizes. They mainly provide carbohydrate, particularly sugars, and fat. Per 100g, they contain 67g of carbohydrate, including 63g of sugars, and 15g of fat, including 7.3g of saturated fat.

Sugars and fat provide energy, and the sugar and saturated fat content is worth noting for people monitoring these in their diet. Frequent consumption of foods containing sugar can contribute to tooth decay. The amount consumed depends on the size of the bar, so these figures are not necessarily the amounts in an individual bar. Full nutrient figures are in the tables below.
