Evidence-based portion sizes for children aged 1-4 years.

: Existing guidelines on how to feed preschool children have left parents and carers unsure about how to offer a diet that will provide their young children with adequate nutrition but prevent excess weight gain. The consequences of malnutrition, such as iron deficiency anaemia and obesity, remain prevalent in this age group and giving parents more specific guidance will help address this. The evidence-based portion sizes from the Infant & Toddler Forum for 1-4-year-old-children have been calculated to meet, but not exceed, their energy requirements and provide all their nutrients, with the exception of vitamin D for which they need a daily supplement. These portion size ranges can be used as serving guides by parents, carers and staff in early years settings. Their use will both reassure parents who worry their preschool children are not eating enough and will help address excess energy intake by toddlers, which is the main cause of obesity.
