Food costs for the current and recommended diet of German infants, children and adolescents

Higher food costs of a recommended diet may be a barrier to the improvement of unhealthy dietary habits. For the assessment of food costs for children, age-specific dietary intakes as well as average food prices must be known. This study is based on the measured food intake from a total of 1668 3-day weighed diet records of children aged from 5 months to 18 years and on recommended dietary intakes for these age groups. Based on the food costs related to the energy intake (Deutschmarks per megajoule; DM per MJ), the recommended diet using common food products does not incur higher costs than the current diet in all age groups. For infants, a diet using commercial infant food conforming to the restrictive German pesticide regulations incurs 50–150% higher food costs than the use of home-made meals. For children and adolescents, the nutritionally inferior quality of the current diet can be improved by a price-balanced interchange of foods, mainly by favouring plant foods instead of meat and confectionery.
