Impacts of Food Insecurity on Physical and Mental Health

Updated: Sep 30, 2023

Food access is the availability and affordability of healthy and nutritious foods. It is a critical issue that affects the well-being of individuals, families, and entire communities. Despite the abundance of food in many parts of the world, millions still lack access to enough food and healthy food options. Food insecurity effects are significant and far-reaching, impacting generations.

In this blog, we will explore the importance of food access and its impact on community health, examine the impact on physical and mental health, and look at immediate actions that can be taken. By better understanding food access, we can create a more equitable and healthy food system for everyone.

Food Insecurity and Community Health

Food access has a significant impact on communities and the health of residents. It is a primary social determinant of health and well-being. Here are some of the ways communities are affected:

  • Health issues: A lack of access to healthy foods can lead to an increased risk of chronic diseases such as obesity, diabetes, and heart disease, impacting healthcare costs. Conversely, access to healthy foods can help prevent and manage these health conditions, leading to improved health outcomes for the community.

  • Economic development: Access to healthy food options can help stimulate economic development in a community. For example, community gardens, farmers' markets, and grocery stores specializing in healthy foods can create jobs and promote local economic growth.

  • Social equity: Access to healthy food options can promote social equity by ensuring all community members can access healthy and nutritious foods, regardless of income or location. Food insecurity among low-income households contributes to health disparities between different populations.

  • Environmental sustainability: Access to healthy food options can also promote environmental sustainability by supporting local food systems and reducing the carbon footprint associated with transporting and storing food.

  • Community engagement: Access to healthy food options can unite a community around shared values and goals. Community gardens, farmers' markets, and other food-related activities can promote community engagement, social connections, public health, and shared purpose.

In addition to these issues, the Economic Research Service (, part of the U.S. Department of Agriculture, reports that the COVID-19 pandemic has worsened the situation. Intervention is needed more than ever.

Food Access and Physical Health

Poor food access can significantly impact physical health, with various negative consequences.

  • Nutrient deficiencies: The effects of food insecurity can lead to nutrient deficiencies that increase the risk of health problems, particularly affecting adolescents' and children's health. For instance, vitamin A, iron, and zinc are essential. A lack of these nutrients can lead to pediatric crises such as a weakened immune system, anemia, and impaired growth and development.

  • Obesity: A lack of access to healthy foods can make it challenging to maintain a healthy weight. Low nutrient processed foods may be the only foods accessible in food deserts, increasing the prevalence of obesity and related health problems.

  • Chronic diseases: Food insecure households run a higher risk of chronic illnesses and need for medical care. When the only foods available are low nutrient, high-calorie foods high in saturated fat, sodium, and sugar is the danger of many health conditions, including the following:

    • Type 2 diabetes

    • Heart disease

    • Hypertension / High Blood Pressure

    • Stroke

  • Anemia: Limited access to healthy foods that contain iron, such as meat, beans, and leafy greens, can lead to anemia, which is a condition where the body does not have enough red blood cells to carry oxygen to tissues and organs.

  • Reduced physical function and quality of life: This is particularly true in older adults who may have difficulty accessing healthy foods and may be at increased risk of chronic diseases.

Food Access and Mental Health

Poor health is not limited to physical conditions. Household food insecurity also affects mental health. Here are some of the mental health issues people may face when they are unable to address food insecurity.

  • Anxiety and Depression: Very low food security is associated with higher rates of anxiety and depression. People who do not have consistent access to food may feel anxious about when they will be able to get their next meal, which can lead to chronic stress and depression.

  • Poor Cognitive Function: When people are food insecure, they may not be getting the proper nutrients that the brain needs to function properly. This can lead to poor cognitive function, making it difficult for people to concentrate, learn new things, or remember information.

  • Gut-brain connection: The gut and the brain are connected, and a healthy diet can support a healthy gut microbiome, which in turn can improve mental health. The gut microbiome is made up of trillions of bacteria that play an important role in digestion, immune function, and mental health. Eating a diet high in fiber, fermented foods, and prebiotics can help promote a healthy gut microbiome. Without food access, this connection is damaged, leading to mood disorders and contributing to conditions such as anxiety and depression.

  • Eating Disorders: Food insecurity can sometimes lead to eating disorders such as binge eating or anorexia. People who do not have consistent access to food may feel a sense of panic when they do have access to food, which can lead to binge eating. On the other hand, people who are unable to access food may feel that they need to restrict their food intake in order to save food for others.

  • Social Isolation: People who are food insecure may feel ashamed or embarrassed about their situation and may avoid social situations as a result. This can lead to social isolation, which can have negative effects on mental health.

Take Action Today

While there is no single solution to address food insecurity, there are actions that each of us can take to help promote access to healthy and nutritious foods. Food programs such as the Supplemental Nutrition Assistance Program (SNAP), WIC, and food stamps can be important interventions, but they have not solved the problem.
