Abstract
Multinational conglomerates and other major food corporations dominate food options in the UK. At Bite Back, a youth-led movement, we have extensively documented the ways in which big food businesses target children as part of their market monopoly. These businesses employ tactics such as misleading health claims, advertising incessantly, promoting junk food every chance they get, as well as excluding young people from critical discussions about public health and reflections on their own impact. However, their negligence extends beyond individual wellbeing. Our research uncovered their significant contribution to environmental degradation, with many of these corporations responsible for alarming levels of carbon emissions. This article explores the dangerous liaisons between multinational conglomerates and the health of the public and the planet. This article also aims to show what youth-led activism looks like in a system rigged against young people, particularly in the face of such powerful and influential businesses.
