The purpose of this research was to identify the contributions of specific foods to intake of fiber among children and adolescents age 2 to 18 years.

We used the 2005-06 National Health and Nutrition Examination Survey to determine the contribution of specific foods to intake of fiber. The dietary intake data collected in the survey were catalogued according to discrete food codes. For this analysis, food codes representing similar foods -- such as the various types of pasta dishes -- were combined to provide an indication of the contribution of distinct food items to intake of the dietary component being studied. That is, the food codes were sorted into 96 mutually exclusive food categories, termed specific foods.

Note: This approach identifies food sources of a given dietary component for the population which may/may not be the richest sources of the component. For that reason, these data may be most informative when the component is over-, rather than under-consumed. If a component is under-consumed, rich sources -- foods with the greatest amount per 100 gram -- may be more relevant.

There are separate tables for the percentage contribution and mean contribution of various foods, stratified by age group, sex, race/ethnicity, and family income.

Key Findings

Among 2-18 year olds, top sources of fiber intake contributing at least 5% are yeast breads, Mexican mixed dishes, pasta and pasta dishes, pizza, ready-to-eat cereals, grain-based desserts, fried white potatoes, and potato/corn/other chips. The major sources varied somewhat by age, gender, race/ethnicity, and income. For example, apples and pears (6%) and bananas (5%) are major contributors for 2-3 year olds, and beans (8%) and apples and pears (5%) are major contributors for all Mexican-American children and adolescents.
