Other research suggests that instead of redefining WIC eligibility requirements, policymakers should better advertise how lenient the requirements are. In a study published in 2005, Craig Gundersen, a professor in the Department of Nutritional Science at the University of Illinois at Urbana-Champaign, found that many parents stop using WIC funds to care for their children after their children reach the age of one year. However, over 35% of these children are in families that are below the poverty line. Only one in nine non-participating children nationwide are ineligible for WIC aid. The research suggests that parents are unaware that children up to five years of age are still eligible for WIC services; consequently, their children are not getting necessary nutrition.
