The coronavirus disease 2019 (COVID-19) pandemic has drastically altered food shopping behaviors, and the resulting economic recession has caused a spike in food insecurity. Since food insecurity is associated with poor diet, especially low intake of fruits and vegetables, food-insecure individuals may disproportionately experience negative health impacts related to poor diet during the pandemic. To assess the relationship between food security status and fruit and vegetable intake during the COVID-19 pandemic, we conducted an online survey of adult residents of the US state of Michigan in June of 2020. Among the 484 survey respondents, 36.2% were classified as food-insecure. Food-insecure respondents consumed fruits and vegetables fewer times per day than food-secure respondents and were more likely to report decreasing their consumption of any type of fruits and vegetables (total, fresh, frozen, and canned) since the pandemic started. For those who reduced their purchase of fresh fruit and vegetable, reasons included poor quality, poor availability, high price, reduced store trips, and concerns of contamination. These findings highlight the need for adequate food assistance during the COVID-19 pandemic and in future pandemics, as well as public health messages that promote healthy eating.

The purpose of this study was to explore the perceived dietary impacts of gardening among members of a gardener support program in Detroit, Michigan. Qualitative interviews were conducted with 28 racially diverse members of the program. Participants reported increasing their consumption of vegetables, trying new vegetables, and decreasing their processed food and meat consumption. Gardeners described factors that contributed to these dietary changes, including knowing that their produce was grown without synthetic chemicals, preferring the taste and freshness of the produce they grew and an emotional connection to their vegetables. Gardening was also associated with some aspects of food security, with most interviewees reporting savings on food due to gardening, and many preserving produce to last beyond the growing season. Gardeners demonstrated strong values towards food, including a distrust of the industrial food system and a desire to make food choices that were beneficial to humans and the environment. This study describes how and why gardening can contribute to dietary change.

Gardening has the potential to improve health by providing access to nature, vegetables, and physical activity. However, scarce research exists on the health impacts of gardening on racial and ethnic minority urban populations in the United States. This study used qualitative interviews to examine the perceived physical and mental health effects of gardening in a primarily African American sample of 28 gardeners. Prominent physical health impacts attributed to gardening included providing an enjoyable source of activity, management of chronic diseases, and improved physical functioning. Participants also reported that gardening improved their mood, relieved stress, was an important part of their spirituality, contributed to their personal growth, and provided an opportunity for helping others. These findings suggest that gardening may improve physical and mental health among diverse groups.

Aim: We explored the feasibility of collecting and analyzing human microbiome data in a longitudinal randomized controlled trial of community gardening. Methods & materials: Participants were randomly assigned to gardening (N = 8) or control (N = 8). Participants provided stool, mouth, hand and forehead microbiome samples at six timepoints. Analyses combined mixed models with Qiita output. Results: Participant satisfaction was high, with 75% of participants completing evaluations. While no microbial effects were statistically significant due to small sample size, the analysis pipeline utility was tested. Conclusion: Longitudinal collection and analysis of microbiome data in a community gardening randomized controlled trial is feasible. The analysis pipeline will be useful in larger studies for assessment of the pathway between microbiota, gardening and health outcomes.
