How far do you think your green beans travelled to get to your plate? And where do all the wonky carrots go? Above all, how do we stop worrying about our food choices and start making decisions that make a difference?

In an effort to make sense of the complex food system we are all part of, Louise Gray decides to track the stories of our five-a-day from farm to fruit bowl, and discover the impact that growing fruits and vegetables has on the planet. Through visits to farms, interviews with scientists and trying to grow her own, she digs up the dirt behind organic potatoes, greenhouse tomatoes and a glut of courgettes.

In each chapter, Louise answers a question about a familiar item in our shopping basket. Is plant protein as good as meat? Is foraged food more nutritious? Could bees be the answer to using fewer chemicals? How do we save genetic diversity in our apples?

Are digital apps the key to reducing food waste? Is gardening good for mental health? And is the symbol of clean eating, the avocado, fuelling the climate crisis?

As pressure grows via social media to post pictures of food that ticks all the boxes in terms of health and the environment, these food stories from the author of the award-winning The Ethical Carnivore are also a personal story of motherhood and the realisation that nothing is ever perfect.
