In common narratives of emergency food assistance, donors likely believe their efforts directly manifest as people consuming their donated food. For example, a person donating canned lima beans during a canned food drive may visualise someone eventually eating those lima beans. However, cultural and socio-economic barriers often exist that prevent people from accessing and consuming the donated food. These barriers are often complex and otherwise well-intentioned donors, volunteers and organisations may not initially consider them.

This commentary article, which draws from existing US emergency food systems literature, uses the imagery of an acorn squash one might find at a US food pantry to conceptualise these barriers in a straightforward way.

Examining emergency food assistance through the lens of the acorn squash problem can help donors, volunteers and organisations better connect with food-insecure people. The lens of the acorn squash problem also allows for deeper critiques of some practices of emergency food systems.

To use cognitive interviewing and pilot testing to develop a survey instrument feasible for administering in the food pantry setting to assess daily intake frequency from several major food groups and dietary correlates (e.g. fruit and vegetable barriers) – the FRESH Foods Survey.

New and existing survey items were adapted and refined following cognitive interviews. After piloting the survey with food pantry users in the USA, preliminary psychometric and construct validity analyses were performed.

Three US food banks and accompanying food pantries in Atlanta, GA, San Diego, CA, and Buffalo, NY.

Food pantry clients (n 246), mostly female (68 %), mean age 54·5 (sd 14·7) years.

Measures of dietary correlates performed well psychometrically: Cronbach’s α range 0·71–0·90, slope (α) parameter range 1·26–6·36, and threshold parameters (β) indicated variability in the ‘difficulty’ of the items. Additionally, all scales had only one eigenvalue above 1·0 (range 2·07–4·71), indicating unidimensionality. Average (median, Q1–Q3) daily intakes (times/d) across six dietary groups were: fruits and vegetables (2·87, 1·87–4·58); junk foods (1·16, 0·58–2·16); fast foods and similar entrées (1·45, 0·58–2·03); whole-grain foods (0·87, 0·58–1·71); sugar-sweetened beverages (0·58, 0·29–1·29); milk and milk alternatives (0·71, 0·29–1·29). Significant correlations between dietary groups and dietary correlates were largely in the directions expected based on the literature, giving initial indication of convergent and discriminant validity.

The FRESH Foods Survey is efficient, tailored to food pantry populations, can be used to monitor dietary behaviours and may be useful to measure intervention impact.
