Resource | Research and Data | Food/Nutrient Analysis Assessing the Nutritional Quality of the FDPIR Food Package

This analysis helps to estimate the nutritional quality of the 2022 FDPIR food package 'as offered' using the Healthy Eating Index scoring algorithm. This will provide an update to the first HEI estimate of the 2014 FDPIR food package. The project also aims to estimate the HEIs of the food packages 'as delivered' to participants.

Resource | Research and Data | Assessing/Improving Operations Study of Nutrition and Activity in Childcare Settings in USDA’s CACFP

Centers and family daycare homes participating in CACFP play an important role in supporting the health and wellness of the children they serve. The Study of Nutrition and Activity in Childcare Settings  is the first nationally representative, comprehensive assessment of the CACFP. Data were collected in program year 2016–17 from CACFP providers and participating children on nutritional quality of meals served, nutrient intake of participating children, meal costs and revenues, and more. Findings serve as an important baseline for the subsequent updates to the meal pattern and nutrition standards, which were implemented in October 2017.
