The health of the planet and its people face considerable challenges; the climate faces threats of irreversible damage while chronic disease and obesity rates continue to rise. Both issues can be attributed in part to humanity’s poor treatment and attitude towards food. Humans throw away much of the nutritious food available, resulting in unhealthful diets and considerable amounts of food waste, leading to harmful greenhouse gas emissions. The current solutions for improving the separate matters of planetary and human health include tradeoffs between the two, despite their interrelatedness. Paradoxically, current research shows that increased fruit and vegetable intake is associated with increased food waste. Current literature has not emphasized a focus on interventions aimed to improve diet quality and food waste simultaneously.Recent research shows that mindfulness can have impacts on human health, such as in relation to chronic pain, mental wellbeing, and self-awareness. Mindful eating specifically has demonstrated improvements in disordered eating behaviors and relationship with food. Yet, no research has been conducted to explore mindful eating in relation to healthful and efficient relationships with food. Therefore, the present study explores mindfulness as a mechanism to improve diet quality and reduce food waste. The protocol presented in the study, titled Mindful Waste Watchers (MWW), was a 4-week novel virtual program incorporating nutrition education, household food waste reduction education, and mindfulness/mindful eating exercises into each lesson. Entry, exit, and 4-week follow-up surveys, each identical, were distributed to participants to assess diet quality, household food waste habits, mindful eating, mindfulness, and food appreciation, primarily by utilization of validated scales. The two primary outcomes evaluated in the present article were diet quality and household food waste behaviors. It was found that the intervention did not produce significant effects for either parameter, suggesting that the protocol was not feasible. However, a significant positive effect was found for food appreciation, a factor that may show promise in future research. While no significant effects were found for the primary outcomes, the findings of this study can be considered in future research targeted towards discovering effective interventions to improve diet quality and reduce household food waste.
