The Feeding Infants and Toddlers Study (FITS) is a dietary intake survey with large, representative, cross-sectional samples of parents or caregivers that provide information on the diet and eating habits of infants, toddlers and preschoolers living in the United States.

The major objective of the FITS is to learn about the nutrient intakes and gaps of the youngest U.S. population group and to understand what foods are being consumed at different ages when the diet of young children is rapidly changing.

Findings from the first FITS conducted in 2002 were published in the Journal of the American Dietetic Association in 2004 with additional findings published in 2006. The second FITS was initiated in 2008 and completed in 2009 using an expanded sample size and age range, 0 to 48 months.
