While some of the nutritional risk standards are clear, Besharov and Germanis further point out that the majority of people on WIC do not clearly exhibit these symptoms or history. They still might have nutritional risk, but they do not meet the definition outlined in the policy. Despite the definition of nutrition risk, the Institute of Medicine's Committee on Scientific Evaluation of WIC Nutrition Risk Criteria pointed out that many states have used "generous" cut-off points and "loosely defined risk criteria." Their research concluded that because the judgment of nutritional risk is left up to the discretion of the doctor, many participants who only partly need WIC's assistance often take the spots of those with greater need.
