Food Security



“Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life”. (World Food Summit, 1996)

The Food Security Working Group is comprised of an interdisciplinary team of researchers and leaders committed to raising awareness of and improving nutrition policies and priorities in the hunger safety net through shared research and evaluation. This Working Group is a part of the Centers for Disease Control and Prevention’s (CDC) Nutrition and Obesity Policy Research and Evaluation Network (NOPREN).

The mission of the Food Security Working Group is to build a network of researchers and leaders from academia, non-profit organizations, government, and other funding agencies to increase the amount and quality of research and evaluation in the area of nutrition and obesity prevention in the hunger safety net setting, and to support and facilitate the development and implementation of evidence-informed policies and practices.

Key Activities and Findings

Overall Goal: To inform nutrition policies and practices implemented in the hunger safety net by providing rigorous, policy-relevant research and evaluation.

Short-Term Goals:

  • Build a network of researchers and leaders with expertise in nutrition policy, research, and evaluation as it relates to the hunger safety net.
  • Identify gaps in the hunger safety net knowledge base
  • Increase the linkage between public health infrastructure and the hunger safety net.
  • Develop 2-4 working group subgroups and recruit subgroup leaders.

Long-Term Goals:

  • Build evidence to support changes to policies, environments, and practices that will optimize the hunger safety net and facilitate desirable changes in dietary intake in food insecure populations.
  • Increase funded high-quality research on the impact of the hunger safety net.
  • Effect change in national, state, local, and tribal policies and practices to improve nutrition standards in the hunger safety net.
