The Impact

Intake of vitamins A, C, and E was evaluated and age and time trends were assessed on the basis of 3-day weighed dietary records (n = 5121) of 2- to 18-year old boys (n = 417) and girls (n = 425) enrolled in the DONALD Study (Dortmund Nutritional and Anthropometric Longitudinally Designed Study) 1986–2001. Intake of vitamin A remains stable over time, intake of vitamin C increases linearly, and intake of vitamin E follows a nonlinear trend. Age trends of vitamins A and C (per MJ) were nonlinear with a minimum at the beginning adolescence, while intake of vitamin E (per MJ) increased linearly. Girls had higher nutrient densities but lower intakes expressed as percent of reference values. Fortified food in total had a higher impact on time trends of nutrient intake than other single food groups defined here. Our results point to the impact of the food industry on long-term nutrient intake, but also underline the necessity of nutrition education even in young age groups to improve vitamin intake.
