The food we eat, the ways we produce it, and the amounts wasted or lost have major impacts on human health and environmental sustainability. Getting it right with food will be an important way for countries to achieve the targets of the UN Sustainable Development Goals and the Paris Agreement on climate change.
A diet that includes more plant-based foods and fewer animal source foods is healthy, sustainable, and good for both people and planet. It is not a question of all or nothing, but rather small changes for a large and positive impact.
The EAT-Lancet Commission has developed a diet which can improve both our health and our world.
