Food SourcesFor some nutrients, two types of information are provided about food sources: identification of the foods that are the major contributors of the nutrients to diets in the United States and the foods that contain the highest amounts of the nutrient. The determination of foods that are major contributors depends on both nutrient content of a food and the total consumption of the food (amount and frequency). Therefore, a food that has a relatively low concentration of the nutrient might still be a large contributor to total intake if that food is consumed in relatively large amounts. SUMMARYGeneral methods for examining and interpreting the evidence on requirements for nutrients are presented in this chapter, with special attention given to infants, children, and pregnant and lactating women, methodological problems, and dietary intake data. Relevant detail is provided in the nutrient chapters. REFERENCESAAP (American Academy of Pediatrics). 1997. Breastfeeding and the use of human milk. Pediatrics 100:1035–1039.
