The development of food portion sizes suitable for 4-18-year-old children used in a theoretical meal plan meeting energy and nutrient requirements.

BACKGROUND: Healthy eating guidelines for school-aged children are available but without advice on portion sizes. This is a concern because consuming large portions is associated with an increased risk of overweight/obesity. The present study aimed to calculate recommended portion sizes for school-aged children based on weight for age and use them to develop a meal plan to meet nutritional needs within energy requirements. METHODS: Portion size data on foods consumed by school-aged children (4-18 years) were extracted from two sources: (i) British National Diet and Nutrition Survey (1997) and (ii) Avon Longitudinal Study of Parents and Children (1997-2006). Foods were allocated to groups based on the UK Eatwell Guide and the US My Plate Model. Portion sizes were developed for a variety of foods. A meal plan that included portion size guidance and met healthy eating guidelines was developed based on the number of portions of each food group needed to meet dietary requirements. RESULTS: Portion sizes were developed for 131 foods that were commonly eaten by children in age groups 4-6, 7-10, 11-14 and 15-18 years. The meal plan met requirements for energy and nutrients as specified by UK dietary reference values, except for vitamin D for which there are few dietary sources. CONCLUSIONS: Food portion sizes informed by usual intake in UK children can help inform dietary advice for a range of childhood settings and for parents. The meal plan included a wide variety of foods to encourage dietary diversity and meet energy and nutrient needs for school-aged children.

Evidenced-based, practical food portion sizes for preschool children and how they fit into a well balanced, nutritionally adequate diet.

BACKGROUND: Healthy eating guidelines for 1-4-year-old children are available but evidence-based portion sizes have not been specified. Parents and early-years providers are concerned about under- or over-feeding young children. The present study aimed to report detailed information about appropriate average portion size ranges and suggest a practical food plan for feeding preschool children, providing adequate nutrient intakes within energy requirements. METHODS: Two sources of information were used to obtain an appropriate portion size range for the types of foods normally eaten by this age group. Median portions of a variety of foods were combined into a food plan fulfilling healthy eating guidelines regarding the number of servings from each food group. The nutrient and energy content of the plan was assessed and compared with recommended adequate nutrient intakes and percentage energy contributions from macronutrients. UK children, aged 1-4 years, taking part in Avon Longitudinal Study of Parents and Children and National Diet and Nutrition Survey, were used in the present study. RESULTS: Portion size ranges were developed for 164 foods. The theoretical food plan using foods with high to medium nutrient density was shown to provide an adequate intake of all nutrients, except vitamin D, for which there are very few food sources. CONCLUSIONS: These practical food portion size ranges could be used both in early years settings and in advice to parents. The food plan emphasises the need to include a variety of nutrient-dense foods if a balanced diet is to be achieved for preschool children.
