Food Sufficiency
Introduction
This toolkit summarizes content from the Food Sufficiency Evidence Accelerator and the MCHbest database. The peer-reviewed literature supporting this work can be found in the Established Evidence database. Use the resources below as you develop effective evidence-based/informed programs and measures.
From the MCH Block Grant Guidance. In 2021, 12.8% of children lived in food insecure households.1 Food insecurity had been decreasing since the Great Recession, but the number of children in food insecure households increased by 10% in 2020 due to the COVID-19 Pandemic. The percentage sharply declined by 20% in 2021, the lowest prevalence on record since 1998. There were several temporary measures taken as part of the Public Health Emergency response to expand benefits and access to programs such as SNAP, WIC, and the National School Lunch Program plus general economic relief.1,2 Large disparities exist by race/ethnicity, disability status, urbanicity, and family structure.3 Food insecurity among children is associated with poor health status, mental health problems, behavioral and socio-emotional problems, and poor educational performance and academic outcomes.4
Goal. To increase the percent of children whose households are always able to afford to eat good nutritious food.

New. Innovative Strategies to Improve Food Sufficiency in State Title V Programs: A Resource Guide to Enhance Food Access Through Title V. This resource guide lists some strategies that Title V programs in ten states and the District of Columbia are currently using to increase food sufficiency following the Individual plus Policy, System, and Environmental (I+PSE) Conceptual Framework.
Overview: Read a summary of the issue related to Title V
Food sufficiency, or the ability of a household to consistently afford and access nutritious foods,1 is the focus of this NPM, although there are many related concepts.* Food insufficiency and food insecurity both are due to insufficient resources to meet basic needs, but their meanings are different.2 Food insecurity is the limited or uncertain availability of safe and nutritionally adequate foods, or the limited or uncertain ability to acquire acceptable foods in socially acceptable ways (without using emergency food supplies, scavenging, or stealing).3 Low food security is reduced quality, variety, or desirability of diet, but with little or no indication of reduced food intake.3 Food insufficiency is considered a more severe form of food insecurity (“very low food security”) and measures whether a household generally has enough to eat.3
Food insufficiency can manifest in various ways, such as households lacking consistent access to enough food, skipped meals, or reliance on unhealthy food options. Access to sufficient nutritious food is critical for healthy development. Poor nutrition affects every demographic, but historically underserved communities bear the burden of diet-related disease, such as obesity and diabetes.4 Research has established an association between food scarcity and poor child health outcomes and diminished well-being.5 Food insecurity among children is associated with poor health status, mental health concerns, behavioral and socio-emotional issues, and poor educational performance and academic outcomes.6,7,8
Families experiencing food insufficiency may participate in programs such as the Supplemental Nutrition Assistance Program (SNAP) or the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program to aid in making food more affordable. Participation in SNAP and WIC during childhood has long-term benefits helping to improve food security across the life course.9 Increased access to school meal programs among children at risk for food insufficiency can also help ensure adequate nutrition and mitigate health issues.10

This NPM is measured through data collected from the National Survey for Children’s Health (NSCH). In 2022, 69.6% of households with young children aged 0-5 could always afford to eat good nutritious meals while 26.4% of households could always afford enough to eat but not always the kinds of foods that were healthy.11 For households with children aged 6-11, 67.2% could always afford to eat good nutritious meals while 27.4% could always afford enough to eat but not always the kinds of foods that were healthy.11
1. Accelerate with Evidence—Start with the Science
The first step to accelerate effective, evidence-based/informed programs is ensuring that the strategies we implement are meaningful and have high potential to affect desired change.

Key Findings and Emerging Issues: Read more from the literature
The following are key findings emerging from the literature:
- Enhanced WIC and SNAP benefits and services have significantly reduced food insecurity rates by providing increased access to nutritious foods and essential resources for low-income families and individuals.26,27,28
- School meal programs play a vital role in providing nutritious meals to children. Evidence supporting an increase in participation rates, reduction of stigma associated with free and reduced-price meals, and expanding afterschool and summer meal programs have proven effective.29,30,31
- Collaborating with community-based organizations and grassroots initiatives can help reduce food insecurity including food banks, food rescue programs, community kitchens, and initiatives that foster local food production and distribution.32,33,34
- Engaging healthcare providers, such as pediatricians and family doctors, in screening for and addressing food insufficiency is an effective method to help identify at-risk families and connect them to appropriate resources and support.35,36,37
Research. Multiple strategies are emerging as potential approaches to advance this NPM, but haven’t been studied with enough rigor to be included in the evidence-based continuum. Additional research is needed to verify outcomes, but initial studies have shown promise of these strategies in MCH settings:
- Implementing policies that address income inequality, and providing income support, to help reduce household food insecurity.38,39
- Utilizing early childhood programs, such as Head Start, to help families develop increased knowledge and skills to support a healthy lifestyle.40
- Identifying and addressing structural barriers that contribute to food insufficiency, such as lack of affordable housing, transportation challenges, and limited availability of healthy food options in certain neighborhoods, to help create more equitable food environments.41
Research Gaps: Learn where more study is needed
Topical Area Knowledge Gaps. Lack of studies on:
- Evaluating the impact of nutritional education and awareness programs on household food choices and children's dietary intake.
- Exploring the effectiveness of community-based interventions in improving food security for children.
Specific Intervention Research Gaps. Lack of studies on:
- Implementing policies that address income inequality, and providing income support, to help reduce household food insecurity.

2. Think Upstream with Planning Tools—Lead with the Need
The second step in developing effective, evidence-based/informed programs challenges us to plan upstream to ensure that our work addresses issues early and is measurable in “turning the curve” on big issues that face MCH populations. Read more about moving from root causes to responsive programs and then use this section to align your work with the data and needs of your populations.
A. Move from Need to Strategy
Use Root-Cause Analysis (RCA) and Results-Based Accountability (RBA) tools to build upon the science to determine how to address needs.
Planning Tools: Use these tools to move from data to action
B. Align with the Needs of the Population
Consider the following findings related to this performance measure.
The Role of Title V: Get ideas on how to implement strategies
Title V agencies can help improve child food sufficiency by:
- Conducting Needs Assessment and Data Collection to further understand the intersection of food insufficiency, SDOH, and health outcomes, and tailor interventions to address the specific needs of vulnerable populations.7,25
- Supporting Outreach and Education by providing clear, relevant, and culturally appropriate nutrition education materials and making connections to resources for nutritious food to empower families to make informed choices.16,25
- Building Partnerships and Collaborations with organizations and local health departments that utilize food banks, community gardens, healthcare providers, and social service agencies to help mitigate food hardships in communities.25
- Educating Policymakers and Informing Policy Changes that address the SDOH and root causes of food insufficiency, such as poverty, income inequality, lack of education, and limited access to affordable housing.25
SDOH and Health Equity Considerations: Identify ways to advance health for all
Social Determinants of Health (SDOH)
SDOH, such as income, education, employment and community resources, play a major role in influencing a family’s ability to access and afford nutritious food. Healthy food may be hard to find or too expensive to afford. Households with lower incomes often face barriers to obtaining high-quality meals. Employment and income are potentially limiting financial resources that families can allocate towards a healthy diet.12
Strategies to address food sufficiency require an equity-focused, SDOH-based approach including:
- Implementing policies focused on increasing income, such as raising the minimum wage, to directly impact a family’s ability to afford enough nutritious food.13
- Ensuring families have access to safe and affordable housing to free up financial resources to afford enough nutrient-dense food.14
- Promoting nutrition education and health literacy programs, such as SNAP-Ed, to empower families and support healthy eating.15,16
- Ensuring benefits for food assistance programs are adequate to support healthy eating patterns, such as permanent increases to the purchasing power of SNAP benefits.16
Health Equity
Systemic racism in the U.S. significantly contributes to food hardships, disproportionately impacting communities of color.17 For example, Black children are nearly three times more likely to live in a household with low food security than White children.9 Efforts to promote health equity must ensure all who have been historically underserved, marginalized, and/or adversely affected by poverty and inequality achieve food sufficiency.18
Strategies to address food sufficiency and promote an equitable food system include:
- Improving access to programs like SNAP and WIC to ensure broader coverage and support, and reducing barriers to participation by streamlining enrollment practices, having a single application, and expanding online shopping options.16,19
- Expanding the reach of the emergency food network in remote, rural, Tribal, and/or low-income areas to increase access to food.16
- Supporting change in the food environment by reducing the price of healthy products and increasing access to healthy options, such as affordable, local, seasonal produce at farmers’ markets.20
- Providing cultural competency training for healthcare professionals to help address the food needs of children and families from diverse backgrounds while tailoring dietary interventions to the specific cultural and linguistic needs of communities to overcome barriers to access.21
Special Considerations: Tease out ways to zoom in on populations of focus
Children with Special Health Care Needs (CSHCN)
The relationship between food sufficiency and CSHCN is of paramount importance, as proper nutrition plays a critical role in their overall well-being and development. In 2022, data from the NSCH revealed that 69.4% of non-CSHCN families and 58.4% of CSHCN families reported always being able to afford good nutritious meals.22 Ensuring food sufficiency for CSHCN requires a comprehensive approach that considers both the specific nutritional needs associated with their health conditions and the potential financial strains placed on families who may require additional resources to meet these needs.23
3. Work Together with Implementation Tools—Move from Planning to Practice
The third step in developing effective, evidence-based/informed programs calls us to work together to ensure that programs are movable within the realities of Title V programs and lead to health equity for all people. Read more about implementation tools designed for MCH population change and then use this section to develop responsive strategies to bring about change that is responsive to the needs of your populations.
