Web 3, or the decentralized web of networks, is a crucial concept in addressing the unique challenges faced by individuals with food-related aversions, as well as in promoting broader efforts toward food justice. Through the use of web-based technologies, web 3 approaches have enabled the organization, tracking, and analysis of data related to dietary habits, dietary deficiencies, and health outcomes associated with certain types of foods. These technologies have also provided resources and avenues for research and advocacy, enabling individuals to better manage their own diets and creating greater awareness of food justice and food access issues.

In particular, web 3 technologies have had a positive impact on food justice and autism food aversions. Autism is a neurodevelopmental disorder that can cause food aversions, which can adversely impact physical and mental health due to the restricted diets that this condition can cause (Tromp-Lozama et al., 2019). A connected global food system that is both nutritious and accessible to individuals with autism is therefore a key component of fostering a thriving global community. Web 3 technologies have provided a platform for community organizing and activism related to food justice issues, such as food access and food security. These technologies have allowed individuals and organizations to share information, coordinate efforts, and advocate for policy changes through networks and forums. This has been especially useful in the context of food deserts, which are areas where access to fresh and nutritious food is limited or non-existent. Web 3 technologies have also enabled the development of tools and resources that can help individuals locate healthy and affordable food in their communities.

In addition to promoting food justice, web 3 technologies have also played a role in addressing food waste. The United Nations estimates that approximately one-third of all food produced worldwide is lost or wasted, with significant environmental and economic consequences (FAO, 2011). Web 3-based approaches have created platforms and systems that can help reduce food waste by connecting surplus food with those in need, such as through food banks and meal delivery services. These technologies have facilitated the tracking and analysis of food waste data, which can help identify trends and patterns and inform strategies for reducing waste.

The growth of web 3 is creating new opportunities for entrepreneurs to build a connected global food system that is nutritious, sustainable, and accessible for all. However, this requires addressing existing socioeconomic disparities within our current food ecosystems, as well as utilizing new technology like blockchain platforms (Goldman, A. 2020). It is also important to recognize the specific implications of food aversions on individuals with autism.

One potential limitation of web 3 technologies in promoting food justice is the issue of digital divide, or the unequal distribution and access to digital technologies and the internet. This can prevent certain individuals and communities from being able to fully participate in and benefit from web 3-based initiatives related to food access and food justice. To address this issue, it will be essential to ensure that web 3 technologies are developed and implemented in a way that is inclusive and accessible to all.

Another potential challenge is the need for regulatory frameworks and policies to ensure the ethical and responsible use of web 3 technologies in the food industry. For example, there may be concerns around issues such as data privacy and security, particularly in the context of sensitive personal information related to dietary habits and health outcomes. It will be necessary to establish clear guidelines and regulations to ensure that web 3 technologies are used in a manner that protects the rights and interests of individuals and communities.

In conclusion, web 3 technologies have the potential to play a significant role in promoting food justice and addressing food-related challenges, such as food aversions and food deserts. While there may be limitations and challenges to overcome, the use of web 3 approaches can enable the development of a connected global food system that is nutritious, sustainable, and accessible for all.
