Feeding Infants & Toddlers Study (FITS)

The Nestlé Feeding Infants and Toddlers Study (FITS) is the largest and most comprehensive dietary intake survey focused on infants, toddlers and preschoolers in the U.S. Started in 2002 by Gerber and conducted in 2008 and 2016 by the Nestlé Research Center in Lausanne, Switzerland, FITS has surveyed nearly 10,000 parents and caregivers to gain a better understanding of the food and nutrient intakes and related lifestyle behaviors among young children. See below for free access to the over 65 peer-reviewed publications from FITS about the nutrient and dietary intakes of infants and toddlers.
