Food insecurity increases the risk of developing diabetes and its complications. In this article, we describe the complex relationship that exists between food insecurity and diabetes and describe potential mechanisms that may underlie this association. We then describe how two different types of interventions, food-is-medicine and federal nutrition assistance programs, may help address both food insecurity and health. Finally, we outline the research, policy, and practice opportunities that exist to address food insecurity and reduce diabetes-related health disparities.

Compared to traditional paper surveys, online surveys offer a convenient, efficient, and socially distant way to conduct human subjects research. The popularity of online research has grown in recent decades. However, without proper precautions, false respondents pose a serious risk to data integrity. In this paper, we describe our research team’s own encounter with survey fraud, steps taken to preserve the integrity of our study, and implications for future public health research.

Food insecurity is associated with increased risk of chronic disease and poor dietary intake. The United States charitable food system, a complex network of food banks, pantries and congregate meal sites, provides food for millions of low-income households each year. Food banks and pantries play a critical role in supporting food security and are an important contributor to dietary intake for its clients. In recent years, there has been an increased focus on sourcing and supplying more nutritious foods within the charitable food system. Despite this, there is a lack of alignment in how the charitable food system defines and tracks the nutritional quality of food.In 2019, Healthy Eating Research convened a panel of nutrition, charitable food system and food policy experts to create a set of evidence-based nutrition standards. Standards were developed based on a review of the literature and existing nutrition ranking systems, while also considering the operational needs and capacity of the charitable food system. The panel provided recommendations for eleven distinct food categories: fruits and vegetables, grains, protein, dairy, non-dairy alternatives, beverages, mixed dishes, processed and packaged snacks, desserts, condiments and cooking staples, and other miscellaneous items. Products are ranked into three tiers, choose often (green), choose sometimes (yellow) or choose rarely (red), based on designated saturated fat, sodium, and added sugar thresholds. This paper outlines the expert panel’s approach and summarizes the barriers and opportunities for implementing these standards across the charitable food system.

Women with low household income and from racial/ethnic minority groups are at elevated risk of food insecurity. Food insecurity during pregnancy is associated with overall less healthy diets, lower intake of the pregnancy-supportive nutrients iron and folate, and significant variations in diet across the course of a month. The goal of this study was to explore the impact of an ongoing $40/month supplement for fruits and vegetables (F&Vs) provided to pregnant people enrolled in the Special Supplemental Nutrition Program for Women and Children (WIC). Our primary outcome was food insecurity using the USDA 6-item survey, and our secondary outcome was dietary intake of F&Vs based on the 10-item Dietary Screener Questionnaire. Participants in intervention and comparison counties completed surveys at enrollment and approximately three months later (n = 609). Mean ± SD food insecurity at baseline was 3.67 ± 2.79 and 3.47 ± 2.73 in the intervention and comparison groups, respectively, and the adjusted between-group change from baseline to follow-up in food insecurity was 0.05 [95% CI: −0.35, 0.44] (p > 0.05). F&V intake (in cup equivalents) was 2.56 ± 0.95 and 2.51 ± 0.89 at baseline in the two groups, and the adjusted mean between-group difference in changes from baseline was −0.06 [−0.23, 0.11] (p > 0.05). Recruitment and data collection for this study coincided with the most intensive of America’s COVID relief efforts. Our results may indicate that small increases in highly targeted food resources make less of a difference in the context of larger, more general resources being provided to individuals and households in need.

Proper nutrition is critical for maternal and neonatal health. In January 2017, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in San Francisco, California, began providing an additional $40 per month in fruit and vegetable (F&V) benefits to pregnant clients with the goal of improving food security and nutrition-related outcomes. We evaluated whether pregnant women on WIC who received this additional F&V benefit exhibited better perinatal and birth outcomes compared with those who received standard WIC benefits. We used 2010–2019 birth certificate data from the National Center for Health Statistics. The intervention group consisted of WIC participants living in San Francisco (SF) County (intervention county) and whose first trimester started after January 2017. We used a quasi-experimental synthetic control method to compare trends between the intervention and control groups (a weighted sample of other California counties that did not distribute additional F&V benefits). Outcomes included low birth weight, preterm birth, small-for-gestational-age, gestational diabetes, and gestational weight gain. No significant differences in maternal and neonatal outcomes among WIC recipients in SF and synthetic control group were observed after the F&V benefits were distributed. Prior studies have shown that additional F&V benefits have positive effects on maternal and infant outcomes, indicating that F&V vouchers are a promising strategy for supporting equitable health outcomes. Our null results suggest that more rigorous research is needed to determine their optimal dose and duration, especially in high-cost-of-living areas, and to examine more upstream and structural interventions.

In June 2019, California expanded Supplemental Nutrition Assistance Program (SNAP) eligibility to Supplemental Security Income (SSI) beneficiaries for the first time. This research assesses the experience and impact of new SNAP enrollment among older adult SSI recipients, a population characterized by social and economic precarity. We conducted semi-structured, in-depth interviews with 20 SNAP participants to explore their experiences with new SNAP benefits. Following initial coding, member-check groups allowed for participants to provide feedback on preliminary data analysis. Findings demonstrate that SNAP enrollment improved participants’ access to nutritious foods of their choice, contributed to overall budgets, eased mental distress resulting from poverty, and reduced labor spent accessing food. For some participants, SNAP benefit amounts were too low to make any noticeable impact. For many participants, SNAP receipt was associated with stigma, which some considered to be a social “cost” of poverty. Increased benefit may be derived from pairing SNAP with other public benefits. Together, the impacts of and barriers to effective use of SNAP benefits gleaned from this study deepen our understanding of individual- and neighborhood-level factors driving health inequities among low-income, disabled people experiencing food insecurity and SNAP recipients.
