A toxic relationship: ultra-processed foods & plastics.

Background: Among the crises engulfing the world is the symbiotic rise of ultra-processed foods (UPFs) and plastics. Together, this co-dependent duo generates substantial profits for agri-food and petrochemical industries at high costs for people and planet. Cheap, lightweight and highly functional, plastics have ideal properties that enable business models to create demand for low-cost, mass-produced and hyper-palatable UPFs among populations worldwide, hungry, or not.

Can virtual events achieve co-benefits for climate, participation, and satisfaction? Comparative evidence from five international Agriculture, Nutrition and Health Academy Week conferences.

The advancement of science and evidence-based solutions for planetary health increasingly require interdisciplinary and international learning and sharing. Yet aviation travel to academic conferences is carbon-intensive and expensive, thus perpetuating planetary health and equity challenges. Using data from five annual international Agriculture, Nutrition and Health Academy Week conferences from 2016 to 2020, we explore whether moving to virtual conferencing produced co-benefits for climate, participation, attendee interaction, and satisfaction.

Trust and responsibility in food systems transformation. Engaging with Big Food: marriage or mirage?

Concentration of power among transnational 'Big Food' companies has contributed to food systems that are unsustainable, unhealthy and inequitable for people and planet. Given these commercial determinants of health, if 'food systems transformation' is to be authentic-more than a passing narrative-then leveraging Big Food is paramount. To this end, researchers, practitioners and policy-makers are increasingly encouraged to engage with these powerful entities.

A systematic scoping review of environmental, food security and health impacts of food system plastics.

Plastic pollution arising from food systems is driving policies for reduction, removal, reuse and recycling, but literature on plastic uses and outcomes across subsectors is fragmented. We use a systematic scoping review to describe the extent, range and nature of published evidence since 2000 on seven major plastic types used at any point within food systems and their quantifiable effects on the environment, food security and human health. Although the majority of publications focus on agricultural production, relatively fewer consider retail, household and food waste disposal plastics.
