Croissants are baked pastries made from layers of dough and fat. They mainly provide carbohydrate and fat, which supply energy. Per 100g, the croissants described here provide 1563 kJ of energy, 43g of carbohydrate and 20g of fat, including 9.8g of saturated fat. They also contain some protein and fibre.

Carbohydrate is a source of fuel for the body, while fat helps the body absorb fat-soluble vitamins. The saturated fat and energy content are worth noting for people monitoring their intake. Croissants also contain salt, and the amount eaten affects overall intake. Full nutrient figures are provided in the tables below.
