Nutrition Security vs. Food Security

  • Food insecurity affects nutrition negatively and increases diet-related disease risk.

  • Traditional food security tools do not adequately measure nutritional quality.

  • Households may be food-secure but still experience nutritional insecurity.

Identify health outcomes related to food insecurity.

Health outcomes related to food insecurity include:

  • Increased risk of nutrition-related diseases such as obesity, diabetes, and heart disease.

  • Higher rates of morbidity and mortality linked to poor diet quality.

  • Greater healthcare costs associated with treating diet-related health issues.

  • Mental health challenges, including anxiety and depression, stemming from the stress of food insecurity.

  • Impact on children’s growth and development, leading to long-term health implications.

What is the limitation of major clinical and public health tools? What (new) tools potentially address this limitation?


Major clinical and public health tools related to food security often do not adequately measure nutritional quality. This limitation means that while a household may be classified as food-secure, it does not necessarily ensure they have access to healthy, nutritious foods.

To address this limitation, new tools are being developed, such as the Nutrition Security Screener. This tool provides complementary insights by assessing challenges related to obtaining healthy foods and enhances the understanding of nutrition security beyond traditional food security measures.

Why is it challenging to assess diet quality?

Assessing diet quality is challenging due to several factors:

  1. Subjective Nature of Dietary Reporting: Individuals may have difficulty accurately recalling their food intake, leading to misreporting.

  2. Variety in Food Choices: The wide variety of foods consumed and their preparation methods complicate standard assessments.

  3. Cultural and Socioeconomic Factors: Different cultural backgrounds and socioeconomic statuses can influence dietary habits, making it hard to apply a one-size-fits-all measure of diet quality.

  4. Limitations of Traditional Tools: Many existing tools measure caloric intake or food security but do not comprehensively evaluate the nutritional quality of foods.

  5. Variability in Nutritional Needs: Nutritional requirements can vary widely based on age, sex, health status, and physical activity levels, adding complexity to assessing diet quality effectively.

Approaches to Achieve Nutrition Security in Health Care Settings

Health impacts of poor nutrition security

Health impacts of poor nutrition security include:

  • Increased risk of nutrition-related diseases such as obesity, diabetes, and heart disease.

  • Higher rates of morbidity and mortality linked to poor diet quality.

  • Greater healthcare costs associated with treating diet-related health issues.

  • Mental health challenges, including anxiety and depression, stemming from the stress of food insecurity.

  • Impact on children’s growth and development, leading to long-term health implications.

Impacts on health systems from addressing nutrition security

Addressing nutrition security can have several impacts on health systems, including:

  1. Reduced Healthcare Costs

    • By preventing nutrition-related diseases like obesity and diabetes, health systems can lower the overall costs associated with medical treatment and management of these conditions.

  2. Improved Patient Outcomes

    • Better nutrition security can lead to healthier populations, which directly improves patient outcomes, reduces morbidity and mortality rates, and enhances the overall effectiveness of healthcare interventions.

  3. Enhanced Healthcare System Efficiency

    • Focusing on nutrition security may lead to more efficient use of healthcare resources by reducing the need for acute care services and hospitalizations associated with diet-related illnesses.

  4. Increased Demand for Nutrition Services

    • As awareness of nutrition security grows, there may be a greater demand for nutrition counseling, education programs, and medically tailored meals, leading to expansion in services offered by health systems.

  5. Collaboration Across Sectors

    • Addressing nutrition security may foster collaboration between health, agriculture, and education sectors, leading to integrated approaches that enhance community health strategies.

  6. Focus on Preventive Care

    • Health systems may shift more towards preventive care measures, recognizing the importance of nutrition in preventing diseases rather than solely focusing on treatment.

Describe the different food security screening tools, what they’re used for, and limitations

Different food security screening tools are used to assess the availability and accessibility of adequate food. These tools include:

  1. USDA Household Food Security Survey Module:

    • Use: Assesses the degree of food insecurity and hunger at the household level in the United States.

    • Limitations: May not fully capture the nutritional quality of food or specific dietary needs, leading to potential underreporting of nutrition insecurity.

  2. Hunger Vital Sign:

    • Use: A two-question screening tool used in healthcare settings to identify food insecurity among patients.

    • Limitations: While quick and efficient, it may overlook nuances of dietary quality and fail to optimize follow-up resources for those in need.

  3. Nutrition Security Screener:

    • Use: Designed to assess challenges related to obtaining healthy foods and goes beyond just food availability.

    • Limitations: Still in development and not widely implemented yet, limiting its usability for larger-scale assessments.

  4. Food Insecurity Experience Scale (FIES):

    • Use: A tool developed by the FAO to measure people's experiences with food insecurity, globally.

    • Limitations: Primarily focuses on food availability and does not provide detailed insights into nutritional quality or access factors.

Overall, the limitations of traditional food security tools often revolve around their lack of comprehensive evaluation of nutritional quality and potential misclassification of households as food-secure when they may be experiencing nutritional insecurity.

Figures in the paper (Exhibit 1 and Exhibit 2) - what are the main takeaways from each and how could you apply them?

  • Exhibit 1 (increasing interest in nutrition security): food sufficiency, food security, and nutrition security all contribute to hunger, diet quality, disease management, and disease prevention + food is available, nutritious food is accessible and affordable, nutritious food is used, nutritious food availability is stable

  • Exhibit 2 (interventions that represent a continuum from preventions): Pyramid (as you move up, it’s more individualized and costly [treating vs. preventing at the bottom)

    • Medically tailored meal programs

    • Medically tailored food packages

    • Produce prescription program

    • Government nutrition security programs (SNAP, WIC, school meals)

    • Population-level healthy food policies and programs → has the most breadth, biggest population focused one
