Food rescue programs improve diets but fall short on nutrition, review finds

Food rescue programs are widely celebrated for keeping edible food out of landfills and getting it to people in need, but a new systematic review suggests their nutritional value deserves closer scrutiny. The review, published in npj Science of Food, followed PRISMA guidelines and searched PubMed, Scopus, Web of Science, and gray literature via Google Scholar for English-language, peer-reviewed empirical studies evaluating the nutritional outcomes of food rescue initiatives. Forty-eight studies met the criteria.

The included studies clustered into five thematic domains: nutritional intake, food security, food basket quality, nutritional status, and nutritional behavior and environment. Improved dietary intake was frequently reported across the literature, yet the review found that inadequacies in fiber, vitamins, and minerals persisted even among program recipients. In other words, rescued food helped people eat more, but not always better.

Food security improvements were documented in 11 intervention studies, although the review noted that baseline food insecurity in these populations remained strikingly high, ranging from 46 to 95.3 percent. That gap matters: even where programs measurably reduced food insecurity, many participants continued to face substantial deprivation, suggesting that rescued food alone cannot close the gap.

Audits of the food baskets themselves revealed mixed quality. Limited anthropometric and biochemical assessments pointed to persistent challenges among recipients, including obesity and micronutrient deficiencies, underscoring that quantity of food does not guarantee nutritional adequacy.

Not all models performed equally. The review found that approaches integrating food provision with education, along with client-choice models that let recipients select their own items, showed more promising outcomes.

The authors argue that the field needs standardized, context-sensitive metrics that go beyond calorie counts to capture diet quality and health outcomes. Future initiatives, the review concludes, should adopt multi-component approaches, recipient empowerment strategies, and cross-sector collaborations to maximize health benefits and align with global nutrition and sustainability goals.

As an early-release, open-access article that is citable and carries a permanent DOI but remains subject to further edits before the final version of record, the review offers a timely evidence base for policymakers and charities alike. Its central message is clear: food rescue programs offer environmental and social benefits, but turning rescued calories into rescued nutrition requires deliberate design, better measurement, and a shift toward empowering the people these programs serve.
