 The most extensive study on nutrient availability was published in 1996, which concluded that nutrition did not change significantly after the implementation of the NAP program for all beneficiaries, however most improvements were noted for very low-income beneficiaries versus their non-participating equivalents.Although these three studies have been used by the federal government and other entities to understand the impact of the NAP program's benefits, the data used by the authors dates back to the periods between 1977 and 1984, providing limited relevant information for the current program of today.Additionally, subsequent research and analysis have revealed insufficiencies in the methodology applied by the authors of all three publications, thereby casting doubt on whether a definitive conclusion of the program's overall impact has been established.
