      abstract = {Currently, the effects of the Food Stamp Program on the  food choices and diet quality of participants are the  subject of much debate. Improved evaluation of the  nutrition and health effects of the program would be of use  to program and policy officials, but most of the existing  research is limited by three key factors: the difficulty in  separating the effect of the program itself from other  factors that may be related to program participation (that  is, selection bias); relative age of the data (which do not  capture current programs or population behaviors); and use  of outdated dietary standards and assessment methods. This  brief describes current ERS activities to address these  problems and improve evaluation.},
