Food security is defined by the US Department of Agriculture (USDA) as “access by all people at all times to enough food for an active, healthy life.” Conversely, food insecurity is defined as a household level economic and social condition of limited or uncertain access to adequate food and is a key social determinant of health that can negatively impact nutrition and health outcomes. In 2021, the USDA reported that 10.2% of the US population met criteria for food insecurity. Recognition of the impact of food insecurity on the patients and families that we serve as Allergy/Immunology healthcare providers is critical to promote health equity and optimize health outcomes. This review focuses on food insecurity and allergic disease from the perspective of key multi-sector stakeholders within Allergy/Immunology and from the larger healthcare arena, highlighting key resources and initiatives important to patients. Collectively, as specialists in Allergy/Immunology and within the medical field more broadly, we must leverage our unique roles as we interface with patients and families and serve as committed advocates for change. Developing innovative strategies to promote health equity can provide a pathway forward for all children, adults and families to gain access to healthy, nutritious food as part of their routine lifestyle. This is our Call to Action.
