Deliberate Actions to Weaken the Federal Nutrition Safety Net
This article shares the critical role of federal nutrition programs.

GW’s Nurturing Opportunity and Understanding Resources to Improve Student Hunger (NOURISH) study
This study found that more than one‑third of students experienced food insecurity during Fall 2024 and that those facing food insecurity reported significantly poorer physical health, high stress, and limited use of available campus food resources. The report concludes that stronger outreach, better‑coordinated support, and evidence‑based interventions are needed to meet students’ unmet food needs.
