Who picked your Fairtrade banana? Where do all the wonky carrots go? And if we’re being encouraged to eat five-a-day, just how much damage are we doing to the world we live in through food miles? We all know that as a nation our mental health is in crisis. But a crucial part of the solution – what we eat – is being ignored. Gray, author of Avocado Anxiety and Other Stories About Where Your Food Comes From, tracks food from farm to fruit bowl, unpacks the dilemmas we face in trying to eat well and ethically, and helps us discover the impact that growing fruits and vegetables has on the planet. Psychologist Wilson, author of Unprocessed: How the Food we eat is Fuelling our Mental Health Crisis, reveals the role of food and nutrients in brain development and mental health. They talk to Hay Festival’s Sustainability Director Andy Fryers.
