Several crucial topics were discussed during the presentation, shedding light on the complexities and challenges of promoting sustainable food practices. The discussion revealed that while behavioural outcomes are still unclear, they are preferred over mere intentions. The concept of "green food" was explored, alongside criticisms of vertical farming for its high energy consumption and questions about its sustainability. This discussion is vital for shaping future policy directions.

Some green foods are perceived as environmentally and socially unfriendly. Issues such as child labor in avocado farming and supply chain failures were highlighted, prompting a debate on the term "green food" and the potential of growing one's own greens as an alternative.

A significant query was raised about the relevance of home-growing sources in pre- and post-surveys for growers. Dr. Dorotic acknowledged the need to use individual before-and-after differences for a more accurate comparison. A robust discussion developed around the trustworthiness of sources promoting the growing of microgreens. The effectiveness and acceptability of these interventions depend on whether the message comes from government, firms, or civil society organizations. Each source has its own challenges regarding trust and implementation reach. 

The attending scholars endorsed the psychological mechanism of closeness to nature driving the effect, rather than improved competence. It was suggested to manipulate both closeness to nature and competence in future studies to align with the IKEA effect assumptions.

The insights gained from the Harvard presentation will undoubtedly inform and refine the ongoing research and interventions of the SmartFood project. The team's commitment to addressing these complex issues is evident, and future studies will incorporate the valuable feedback received.

The SmartFood presentation at Harvard University marked an important moment for the project, reinforcing its innovative approaches and highlighting areas for further investigation. The positive reception and constructive discussions set a promising path for the continued success and impact of the SmartFood initiative.
