The National Academy of Sciences was established in 1863 by an act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.
The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. C. D. Mote, Jr., is president.
The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.
The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) began 40 years ago as a pilot program and has since grown to serve more than 8 million pregnant women, and mothers and their infants and young children. Today the program serves more than a quarter of the pregnant women and half of the infants in the United States, at an annual cost of about $6.2 billion. Through its contribution to the nutritional needs of pregnant, breastfeeding, and postpartum women; infants; and children under 5 years of age, this federally supported nutrition assistance program is integral to meeting national nutrition policy goals for a significant portion of the U.S. population.
To assure the continued success of WIC, Congress mandated that the Food and Nutrition Service of the U.S. Department of Agriculture (USDA) reevaluate the program’s food packages every 10 years to assure they remain aligned with the goals of the Dietary Guidelines for Americans (DGA). In 2014, USDA asked the Institute of Medicine (IOM) to undertake this reevaluation. This complex task included consideration of whether or not WIC participants should be permitted to purchase white potatoes with the cash value voucher (CVV), a part of the benefit package that provides access to vegetables and fruits. In its first of three reports, published early in 2015, the committee recommended that white potatoes be allowed as a WIC-eligible vegetable for purchase with the CVV. The second report of this series, published in 2016, provided a summary of the work of phase I of the study as well as the analytical underpinnings for phase II. This is the third and final report in this series. It provides further data analyses, a regulatory impact analysis, and the committee’s final recommendations.
