Food composition tables serve as a basic reference for data on nutrients in commercial baby food. Sources of unpublished data include industry, government agencies, and studies under USDA. Data are presented for 217 items. Data are given per 100 grams of food, in terms of two common measures of food for most items, and as the amount in 1 pound. Standard errors in the value are included. Sample means were weighted for each manufacturer by its percentage of the baby food market. Group or type of baby food is in alphabetical arrangement. Data are given for strained, junior, and toddler foods. Values for nutrient content reflect the increased vitamin and mineral content fortification of cereal products and added ascorbic acid in fruit juices and some fruits. Nutrient content is given in proximate components, minerals, vitamins, lipids, and amino acids.
