title: Critical Dietary Habits in Early Childhood: Principles and Practice.
abstract: The adequacy of a diet is usually evaluated based on nutrient intake. As people eat foods but not nutrients, food-based dietary guidelines (FBDG) are needed. To evaluate dietary habits in infants and young children, the following stepwise approach is suggested: (1) develop country-specific FBDG to identify the potential of common nonfortified foods to ensure adequate nutrient intake and (2) examine potential 'critical' dietary patterns if main food groups are excluded, such as in vegetarian diets or if a family's precarious social status leads to food constraints. The German FBDG for infant and child nutrition demonstrate that a well-designed mixture of common foods results in an adequate supply of nutrients, except for vitamin D, iodine and iron. The following solutions are feasible to address deficiencies in these critical nutrients: routine supplementation (vitamin D), fortified complementary food consumption or supplementation for infants as well as inclusion of table salt in the family diet for children (iodine), and individual pediatric care for infants at risk (iron). In the exclusion of food groups of animal origin from vegetarian diets, several nutrients are at risk of becoming deficient if not substituted. Existing studies characterizing vegetarian children are rare. These were mainly published in the 1980s and 1990s and were biased towards a high social status. Thus, firm conclusions on today's dietary practices and health statuses of European vegetarian children cannot be drawn. A social gradient exists for food patterns and dietary quality in children, but energy intake need not necessarily be affected. Scenarios in Germany suggest that families on unemployment assistance can afford to eat a diet compliant with German FBDG only if they restrict food selection to basic food. Yet, the question of how families cope with financial constraints in everyday life remains. In conclusion, well-designed FBDG provide various opportunities to identify critical nutrients and critical food habits in early childhood and beyond.
