The translational implications of applying multiple measures to evaluate the nutrient quality of the food supply: a case study of two food pantries in Montana

Validating a Nutrition Ranking System for Food Pantries Using the Healthy Eating Index-2015

In 2020, charitable food organizations began adopting Healthy Eating Research (HER) nutrition guidelines, which rank individual foods in tiers (e.g., green, yellow, or red) based on each food’s nutrient profile. This study aimed to validate this HER tier-ranked system against the Healthy Eating Index-2015 (HEI) and develop a formula to summarize the percentages of tier-ranked foods in an overall nutritional quality index that correlated with HEI. Using secondary data of foods selected by clients in 16 Minnesota food pantries (n = 503 “client carts”), we generated an HEI score and percentages of green, yellow, and red foods for each cart. As validation, we tested the association between HEI scores and the percentages of tier-ranked foods and compared the means of the tier-ranked variables using quintiles of the HEI scores. HEI scores were positively associated with percentages of green foods and negatively associated with percentages of red foods. Next, we used statistical learning to generate weights to maximize the correlation of the tier-ranked variables and the HEI scores and used these weights to create an index. The index demonstrated a moderate-to-strong correlation with HEI and can be used as a single measure to summarize the overall nutritional quality for sets of tier-ranked foods.

The Influence of the COVID-19 Pandemic on the Food Supply in the Emergency Food System: A Case Study at 2 Food Pantries

BACKGROUND

The onset of the coronavirus disease 2019 (COVID-19) pandemic increased demand for emergency food assistance and has caused operational shifts in the emergency food system.

OBJECTIVE

This research explored how the initial phase of the COVID-19 pandemic influenced the food supply of 2 food pantries.

METHODS

A case study approach was applied to collect data during the initial phase of the COVID-19 pandemic. Food supply data were collected weekly at 2 food pantries in southwest Montana for 17 wk in 2020. Surveys and interviews were conducted with food pantry clients and staff, respectively. Descriptive statistics and inferential statistics were applied to analyze quantitative data. Food supply data were analyzed using the Healthy Eating Index (HEI)-2015, NOVA system, and Unprocessed Pantry Project (UP3) Framework. Thematic analysis was applied to qualitative data.

RESULTS

The food boxes collected between the 2 food pantries (n = 43) had a mean (± SD) total HEI-2015 score of 76.41 ± 7.37 out of a possible score of 100. According to both the NOVA and the UP3 Framework, 23.4% of the total food distributed was ultra-processed food. Of the food distributed, 50.0% and 48.3% was fresh, unprocessed food according to NOVA and UP3 Frameworks, respectively. From staff interviews, 3 themes arose that describe the food pantry operations that experienced change during the COVID-19 pandemic, including food procurement, distribution preparation, and food distribution. Nine supporting subthemes describing the causes and consequences of the operational themes were identified. Staff perceived that the nutrient quality of the food boxes increased from food distributed previously to the COVID-19 pandemic, whereas over one-third (39.4%) of food pantry clients who responded to surveys preferred the food box model.

CONCLUSIONS

The COVID-19 pandemic has caused enormous operational challenges within food pantries. Food pantries overcame these challenges by swiftly and effectively altering operations so as to continue to distribute nutritious food boxes to pantry clients.
