['We evaluated how well the diet of Norwegian children and adolescents with type 1 diabetes fulfils the Nordic and European dietary recommendations, focusing on parameters affecting prevention of atherosclerosis. We also compared the diet of this patient group with that of healthy same-age control subjects.', 'A total of 177 children and adolescents with type 1 diabetes (9-10-year-olds, 12-13-year-olds) and 1,809 healthy same-age control subjects recorded their food intake for 4 days in precoded food diaries.', 'In children and adolescents with type 1 diabetes the percentage of energy (E%) from fat (33-35 E%) and saturated fat (14-15 E%) was higher than recommended for that group. Furthermore their intake of fibre was lower (16-19 g/day) than current recommendations. There were no differences in energy intake between diabetic subjects and healthy control subjects. Percentage of energy from fat (mean difference: 3.4 E%, p < 0.001) and saturated fat (mean difference: 1.0 E%, p < 0.001) was significantly higher among diabetic subjects than control subjects. Intake of fruits and vegetables was low (210 g/day) compared with recommendations, both in the diabetic and control subjects.'] Do children and adolescents with type 1 diabetes eat a more atherosclerosis-prone diet than healthy control subjects?
