The first science-based diet that tackles both the poor food eaten by billions of people and averts global environmental catastrophe has been devised. It requires huge cuts in red meat-eating in western countries and radical changes across the world.
The “planetary health diet” was created by an international commissionseeking to draw up guidelines that provide nutritious food to the world’s fast-growing population. At the same time, the diet addresses the major role of farming – especially livestock – in driving climate change, the destruction of wildlife and the pollution of rivers and oceans.
Globally, the diet requires red meat and sugar consumption to be cut by half, while vegetables, fruit, pulses and nuts must double. But in specific places the changes are stark. North Americans need to eat 84% less red meat but six times more beans and lentils. For Europeans, eating 77% less red meat and 15 times more nuts and seeds meets the guidelines.
The diet is a “win-win”, according to the scientists, as it would save at least 11 million people a year from deaths caused by unhealthy food, while preventing the collapse of the natural world that humanity depends upon. With 10 billion people expected to live on Earth by 2050, a continuation of today’s unsustainable diets would inevitably mean even greater health problems and severe global warming. Read more
